To better understand the benefits, costs, and risks associated with this investment, Forrester interviewed six decision-makers across four organizations with experience using SmartBear’s API Solutions. For the purposes of this study, Forrester aggregated the experiences of the interviewees and combined the results into a single composite organization, which is a global organization with a geographically distributed workforce of 10,000 employees; 200 developers, designers, QA testers, and product owners have a license to use SmartBear’s API solutions.

Interviewees said that prior to using SmartBear’s API solutions, their organizations designed APIs with code-first practices and lacked a standardized and collaborative way to test and document APIs. Developers were often unsure what APIs existed within their own environment, and API consumers had challenging onboarding experiences. These time-consuming processes often led to redundant work and inefficiencies across the API development lifecycle.

After the investment in SmartBear’s API solutions, the interviewees’ organizations developed their APIs using a design-first mindset. This enhanced collaboration across developers, architects, and product teams and led to faster design, test, and documentation workflows. Developers began to reuse existing APIs for different use cases as discoverability improved, and API consumers gained a clearer understanding of how to onboard APIs efficiently.

Key Findings

Quantified benefits. Three-year, risk-adjusted present value (PV) quantified benefits for the composite organization include:

  • API development efficiencies. The composite organization develops new APIs each year: 75 in Year 1, 100 in Year 2, and 125 in Year 3. In shifting to an API design-first mindset using SmartBear’s API solutions, the composite organization’s developers improve communication with one another, spend less time in meetings documenting APIs, and identify potential challenges sooner. The developers design, document, and test APIs faster, gaining 50% efficiency in their development workflows. Over three years, this is worth $699,000 in time savings.

  • API reusability improvement. API discoverability improves across the composite organization as it documents APIs consistently and accurately. This allows the composite organization’s developers to reuse existing APIs for additional use cases rather than recreating similar APIs on their own. By Year 3, 30% of the APIs available in the catalog are reused. Over three years, this is worth $672,000 in time savings.

  • API consumer support efficiencies. The composite organization’s developers spend less time addressing questions from API consumers because of improvements in contract testing as well as accurate and up-to-date documentation in its portal. API consumers gain the ability to serve themselves rather than meeting directly with the API providers. The developers gain efficiencies of 70% on consumer support tasks as a result of using SmartBear’s API solutions. Over three years, this is worth $151,000 in time savings.

Unquantified benefits. Benefits that provide value for the composite organization but are not quantified for this study include:

  • Developer satisfaction. The composite organization’s developers use SmartBear’s API solution tools to improve their own day-to-day development workflows as well as workflows that require input from colleagues across time zones. This improves developer satisfaction and unlocks their capacity to focus on other initiatives.

  • Cross-functional collaboration. The composite organization’s developers also streamline their communication with other departments, such as information security, that need access to API documentation by pointing these colleagues to the existing catalog within SmartBear’s API solutions.

  • The creation of API quality standards. As the composite organization shifts to an API design-first mindset, it places greater emphasis on API standardization and quality. It uses the centralized repository provided by SmartBear’s API solutions to standardize and track quality-related metrics for recently developed APIs.

  • Process standardization, which influences best practices across teams. The composite organization creates structured and repeatable processes for its API development lifecycle, which leads to operational efficiencies for its developers. This success influences other teams across the composite organization to explore how to standardize their own workflows using technology.

Costs. Three-year, risk-adjusted PV costs for the composite organization include:

  • SmartBear fees. The composite organization pays an annual fee per user, which grants all 200 users access to Design, Portal, Contract Testing, and Test. The composite organization also sets up single-sign-on (SSO) access. Over three years, the composite pays $338,000 in fees.

  • Implementation and ongoing management. The composite organization dedicates 480 hours to the initial implementation effort. Each user receives 3 hours of training to gain familiarity with the solutions before use. On an ongoing basis, the composite organization dedicates 120 hours annually to solution management and administration. Over three years, this costs $127,000 in labor.

The financial analysis that is based on the interviews found that a composite organization experiences benefits of $1.5 million over three years versus costs of $466,000, adding up to a net present value (NPV) of $1.1 million and an ROI of 227%.

“Having a central repository and the ability to have asynchronous communication — everybody working off the same sheet of music — has enabled our API-first mindset and strategy. It has made us a lot more efficient. I think anybody you ask is excited.”

Director, enterprise architecture, retail

“I would tell [a prospect] that the developer experience can be enhanced. We are truly investing time to unlock engineering capacity, and we’ve seen this in improving the way of working for engineers. It’s really clear cut and, ultimately, engineers will fall in love with this because it helps them know exactly what they get. [It can lead to] something very significant in terms of the whole dev cycle in lifecycle management.”

Product owner, financial services

“We’re really looking at enforcing adherence to standards to keep APIs usable, consistent, versionable products using SmartBear’s tools to help align that process.”

Key Challenges

Prior to adopting SmartBear’s API solutions, the interviewees explained that their organizations struggled with siloed API operations, poor API documentation practices, and time-consuming onboarding processes for API consumers. Their development teams designed their APIs using code and subsequently worked with product teams to document APIs after design. API consumers would frequently reach out to the developers providing the APIs, asking for support and better information to help them understand the APIs. Interviewees noted how their organizations struggled with common challenges, including:

  • A lack of enterprise standardization for API development. Interviewees explained that their organizations’ development teams were dispersed across many working time zones. As such, different teams adopted their own processes for developing APIs, which led to inconsistent API quality and extra manual work. The director of enterprise architecture at a retail organization said: “Like any global organization, we face the challenges of time zones and working hours. We have a large contingent in Arizona and in India, which are complete opposite ends of the globe. We struggle with that.” The global enterprise architect at a retail organization said, “Before, we didn’t have one common way for developers and architects to test or document an API.”

  • Inaccessible or nonexistent documentation. Interviewees shared that their organizations struggled to maintain a repository of well-documented APIs, which often meant developers were unaware of which APIs existed within their own environment. Developers also faced manual, time-consuming processes when updating existing documentation; because of this, developers sometimes chose not to make the necessary changes. This led to out-of-date documentation. Turnover within the development team, and especially with third-party contractor resources, also meant APIs went undocumented.
    The director of enterprise architecture at a retail organization said: “There was little to no documentation around APIs. There was really no API catalog, so teams that are relatively close in area or geography weren’t even clear among themselves what APIs existed, how to leverage them, and what capabilities they provided.”
    The product architect at a software organization said: “Whenever we wanted to make changes to the documentation, we had version control [issues]. If three or more developers wanted to make changes, one had to pull the changes and do the code review. Even if there were small textual changes, they needed to do the pull request and submit it for the review. Once it was done, along with all other code changes, we would release the prior total documentation into the servers.”

  • Poor consumer onboarding experiences. Interviewees explained that inconsistent API development and poor documentation practices within their organizations led to challenging interactions with API consumers. The API consumers lacked a clear understanding of API implementations and would demand extra time from the developers to gain clarity. The VP of platform and infrastructure at an IT organization said: “The documentation was just flat PDF files, not live, up-to-date documentation. Our members would go into our intranet, which we call our community, and they’d have to search for the API, download the PDFs, and then go try to use those. There was no ‘try it out’ functionality like SmartBear has. They’d have to use their favorite tool to try that out.”

“Prior to adopting an API-first and standardization model, there was no pre-design. We designed in code, and the developers worked with the product teams to then document it. That creates challenges, right? There was no enterprise standardization for our APIs. Pockets of teams were doing things differently.”

VP of platform and infrastructure, IT

Investment Objectives

The interviewees searched for a solution that could:

  • Enable an API design-first mindset.

  • Unify a global team around consistent and standardized processes.

  • Free up developer capacity.

  • Modernize developers’ toolset.

  • Ensure APIs are reusable and adhere to quality standards.

After a request for proposal and business case process that evaluated multiple vendors, the interviewees’ organizations chose SmartBear’s API solutions and began deployment.

  • The product architect at a software organization said: “I was working with another company that used [SmartBear’s] Swagger where I experienced the benefits of the solution. When I joined my current company seven years ago, I proposed that we needed to incorporate the Swagger solution for its benefit around documentation as [our strategy was to] break down to the microservices.”3

  • The VP of platform and infrastructure at an IT organization said: “About 18 months ago, we started an internal task force to get our hands around our APIs, our documentation, both internally and externally. The goals were to provide our members with more contemporary access to consume and search documentation. SmartBear and Swagger seemed like a really good fit for us to document our APIs and also have the portals for our members to sign in.”

  • The director of enterprise architecture at a retail organization said: “At the time this started, it was under a global dev team and it was budgeted under a set of development tools. We were going through a transformation in our global development space to modernize, and a couple of new leaders joined.”

  • The product owner at a financial services organization said: “A few years back, contract testing was mentioned as part of a standardization opportunity for our templates, which could contribute to the global success of API management. API providers were excited because they said, ‘I’m providing data or access to something, and I want to make sure that someone who’s consuming my service is doing it in the appropriate way.’”

  • The product architect at a software organization said: “We had a reorganization, and our engineering department got an investment to redesign our framework and redesign our APIs. I brought back the Swagger API benefits, and our director of engineering was also aligned with Swagger API. The director presented to the senior leadership, and they agreed to the solution.”

“The adoption within our global dev internal resources was quick and well understood. A lot of those resources are located in Poland and are a good community of folks that share knowledge pretty rapidly. It grew organically more than any major marketing campaign or push from anyone in the organization.”

Director, enterprise architecture, retail

“We are on a level where Swagger is implemented [just as] you use a cup when you drink a coffee. It is not a discussion because the developers and architects can see the benefits. This is the way we start API-first.”

API Development Efficiencies

Evidence and data. According to Forrester, API design is one of the most important aspects of API strategy: It will make or break adoption.4 Using SmartBear’s API solutions, interviewees reported efficiencies across their organizations’ API development lifecycle: from design to document to test. With the shift to an API design-first mindset, interviewees explained how communication across their development and product teams improved. Teams gained the ability to communicate asynchronously, cutting down on time spent answering questions and in meetings documenting APIs together. Interviewees also shared that developers and architects gained the ability to test APIs earlier in their development cycles and identify potential challenges sooner.

  • The product architect at a software organization explained how their software team realized time savings of 15% to 20% in the design phase of their API development lifecycle. They said: “The benefit of Swagger API is the ability to provide the API design-first approach. We first design the APIs without the real code in the backend. By using the linting feature as a shift-left concept, wherein you can test and validate the application without the real implementation, it improves developers’ efficiency.”

  • The product owner at a financial services organization said, “It used to take 20 hours for an API provider to create a template and integrate that with contract testing — and now it’s an hour.”

  • The director of enterprise architecture at a retail organization said: “Swagger has been a big help to make sure that we’re all working off the same sheet of music and we’re able to collaborate. Teams can post comments and updates, and then other teams can leverage them in a different part of the world during their working hours. That’s been a big success of Swagger for us.”
    The same interviewee continued: “[Now] we’re starting to get more adoption [around being API-first]. We have successful stories where we’re able to develop more in parallel and have contracts at least drafted and mutually agreed to before we go out and build or modify the component that’s going to deliver that API or consume that API. This goes back to the efficiency piece. It has allowed us to identify and have those conversations more upfront, where historically we probably would have built the component and the last thing we would have focused on was the integration to the ecosystem around it. Which is where we would discover, ‘Oh, I didn’t account for that attribute,’ or ‘I didn’t realize the consuming system needed to know that, and I’m not handling that in a way that I can share it easily.’ This enables us to discover opportunities or potential challenges sooner in the process.”

  • The senior software engineer project lead at an IT organization said: “First we did an internal pilot with one team that was already under very active API development. They started making a lot of use of the features and, right off the bat, they started using the commenting features when reviewing documents. One person writing the document and other team members jumping on comments, making suggestions for changes, and standardizing processes — all before anybody has invested any time in a line of code. … We saw that immediate efficiency come through.”
    The same interviewee continued: “Our quality engineering team saw efficiencies from first being able to see these designs before any code is released, as they could start creating test cases. Then when they did have code available, they would use the ‘try it out’ functionality within [the] API Hub design to start to test out some of those APIs before doing their automated testing.” The interviewee estimated that testing times were 25% faster for the quality engineering team.

  • The VP of platform and infrastructure at an IT organization explained that their developers save at least an hour of time per API due to eliminating a meeting with their product team for documentation discussion.

“I heard one anecdote from a team lead on the quality side saying this is revolutionary. It was the phrase she used when she was able to start working directly through the ‘try it out’ interface to hit the APIs before they started developing their cases.”

Senior software engineer project lead, IT

“If I look back over the last five years or so, our global development efficiency has improved significantly. Swagger has played a role.”

Modeling and assumptions. Based on the interviews, Forrester assumes the following about the composite organization:

  • The composite organization develops 75 APIs in Year 1, 100 in Year 2, and 125 in Year 3.

  • It takes 160 hours to develop an API in the prior environment.

  • With SmartBear, the composite organization gains efficiencies of 50% in the time to develop an API.

  • The fully burdened hourly rate for a developer is $84. The average fully burdened annual salary for a developer is $175,000.

  • Only 50% of the recaptured work is spent on productive activities.

Risks. The value of this benefit may vary among organizations depending on:

  • The number of APIs developed annually and their design complexity.

  • The time it takes to design, create, and test APIs in their prior environment.

  • Developers’ salaries.

Results. To account for these risks, Forrester adjusted this benefit downward by 15%, yielding a three-year, risk-adjusted total PV (discounted at 10%) of $699,000.

API Reusability Improvement

Evidence and data. Interviewees explained that improved documentation meant API discoverability across their organizations increased. Developers gained a better understanding of which APIs existed and how they could reuse these APIs for additional use cases. Interviewees explained how their developers saved time by leveraging the design-first mindset and templates available in SmartBear’s API solutions and reusing content for other services rather than creating a new API.

  • The product architect at a software organization estimated around 30% to 40% of their APIs are now reused or adapted from existing designs. They said: “The legacy approach involved an [API] customer asking for some attributes and us delivering because one customer asked for it. What we want to do is provide a reusable solution or a scalable solution. [Now, we ask] if the API is following industry standards as well as whether we are adding this attribute only for the benefit of this customer or any other customer.”

  • While not yet fully realized, the global enterprise architect at a retail organization said, “Best case is more than 50% of our APIs can be reusable [as part of our ongoing strategy].”

  • The director of enterprise architecture at a retail organization said: “We are trying to push hard on the reusability piece. I think we’ve been pretty successful in doing so. As a specific example, I was involved in being able to manage the task sequence of a customer enrolling in loyalty, whether that be in the store or on a mobile app or on the web. We had a single standard onboarding flow and then we were able to leverage that same onboarding flow when other programs came up — subscription programs or a ‘pay by your license plate’ experience on the mobile app. Historically, those would have been unique projects handled in their own silo. As a practice and in the use of the tool, we’re able to showcase, ‘Hey, this is what this API already does. I think it meets your use case as well. Let’s talk through it. Showcase it.’ Or ‘We had to make this one tweak because there’s an additional attribute we need to capture in the onboarding flow.’”

Modeling and assumptions. Based on the interviews, Forrester assumes the following about the composite organization:

  • The composite organization develops 75 APIs in Year 1, 100 in Year 2, and 125 in Year 3. Cumulatively, this equates to 75 APIs in Year 1, 175 APIs in Year 2, and 300 APIs in Year 3.

  • In Year 1, 20% of the APIs can be reused. This increases to 25% in Year 2 and 30% in Year 3.

  • It takes 160 hours to develop an API in the prior environment.

  • The fully burdened hourly rate for a developer is $84. The average fully burdened annual salary for a developer is $175,000.

  • Only 50% of the recaptured work is spent on productive activities.

Risks. The value of this benefit may vary among organizations depending on:

  • The number of APIs developed annually and their design complexity.

  • The time it takes to design, create, and test APIs in their prior environment.

  • The extent to which APIs can be reused across use cases.

  • Developers’ salaries.

Results. To account for these risks, Forrester adjusted this benefit downward by 15%, yielding a three-year, risk-adjusted total PV (discounted at 10%) of $672,000.

API Consumer Support Efficiencies

Evidence and data. According to Forrester’s research, internal developers seek to access and provision resources without opening a ticket to a central shared services team. For external developers, the portal isn’t just an API directory: It is a means of improving developer engagement.5 In addition to development efficiencies, interviewees reported that their organizations spent less time addressing API consumers’ needs after implementing SmartBear’s solutions. Interviewees shared that their use of Portal through SmartBear’s API solutions allowed their organizations to customize a branded portal so that external consumers could easily navigate their API catalog. With access to accurate and up-to-date documentation and improvements to contract testing, consumers onboarded APIs quicker. This resulted in less back and forth with the development team.

  • The product architect at a software organization estimated a 30% to 40% reduction in time spent managing API-related questions and onboarding support. They said: “If we want to showcase the Swagger API or our portal documentation to some customers, we go to [domain name]. It is easier for customers to see how the API looks before the implementation. That is super efficiency from our point of view. Previously, we either needed to send some JSON sample requests and responses or emails or [provide] some demos, but now, it’s self-explanatory.”
    The same interviewee continued: “In Swagger, there is an option to generate code using different languages. Once we create our API, if we want to sell to a customer and they want to use our code on their user interface (UI), they can simply go to our Swagger URL and download the software development kit (SDK) in Java or Python and develop their UI application easily. Previously, that was not possible. This is additional value for our customers.”

  • The global enterprise architect at a retail organization said: “We have so many users and a huge enterprise architecture with a lot of systems that have a dependency to each other. If we send out an API that has an incorrect contract, even in the worst case, it can block our business. That’s why it’s so important to have this contract checking so early.”

  • The product owner at a financial services organization said: “Because of several standard templates, onboarding for both consumers and providers used to last a day, which included a bit of time waiting. Now, that has moved to 18 seconds [for some APIs].”

“Consumers ask a number of questions about fields, request forms, and responses when they start consuming our APIs. It was a hand-holding exercise. We needed to set up a number of calls with our lead developers. Now, with Swagger, we don’t do the hand-holding.”

Product architect, software

“Contract testing in the bank is driven by quality. [By] having contract testing as an investment for our squad, we could allow consumers to realize more time savings.”

Product owner, financial services

Modeling and assumptions. Based on the interviews, Forrester assumes the following about the composite organization:

  • Cumulatively, 75 APIs are available in Year 1, 175 in Year 2, and 300 in Year 3.

  • Fifteen APIs are reused in Year 1, 44 are reused in Year 2 and 90 are reused in Year 3.

  • In the prior environment, it takes 10 hours per API to support consumers’ activities.

  • With SmartBear, the composite organization gains efficiencies of 70% in API consumer support activities.

  • The fully burdened hourly rate for a developer is $84. The average fully burdened annual salary for a developer is $175,000.

  • Only 50% of the recaptured work is spent on productive activities.

Risks. The value of this benefit may vary among organizations depending on:

  • The number of APIs developed annually.

  • The extent and complexity of API consumer support provided.

  • Developers’ salaries.

Results. To account for these risks, Forrester adjusted this benefit downward by 15%, yielding a three-year, risk-adjusted total PV (discounted at 10%) of $151,000.

Unquantified Benefits

Interviewees mentioned the following additional benefits that their organizations experienced but were not able to quantify:

  • Developer satisfaction. Interviewees shared how SmartBear’s API solutions unlocked developer capacity, improved their day-to-day workflows, and eased ways of working with other developers and architects. The global enterprise architect at a retail organization said: “We have a huge number of developers who need access to documentation and the ability to test APIs. This is something they can do in Swagger. They say, ‘Wow, that is exactly what we need.’”

  • Cross-functional collaboration. Interviewees emphasized that SmartBear’s API solutions improved visibility into the API development lifecycle, which streamlined collaboration with various teams across their organizations. The director of enterprise architecture at a retail organization shared an example: “As an organization, we have not done a great job documenting a lot of things. Our security team [recently] said, ‘Hey, we’re taking a deep-dive focus on API security. Is there a catalog of APIs?’ And I said, ‘Yes.’ They were so impressed because it’s just that type of thing doesn’t exist in a lot of other areas of our organization, and it made their job really easy.”

  • The creation of API quality standards. According to Forrester’s research, API programs need a strategy for versioning APIs and for governing their compliance with design and security standards.6 Each of the interviewees’ organizations was at a different point in defining and applying API quality standards practices across their development lifecycle. Interviewees explained that ensuring quality was a collaborative initiative and shared how SmartBear’s API solutions provided their organizations with a centralized repository to track these standards.
    The product owner at a financial services organization said: “I became a work group lead for the vision of quality for the bank, leveraging the quality maturity model, which is in development. When a squad starts engineering work — whether they have a product they’re releasing or a feature change — at the point of code to release, they should know their product risks are all solved and taken care of. It’s at that critical moment that we can discuss knowledge gaps.”
    The senior software engineer project lead at an IT organization said: “We are starting to define standards that we want our APIs to adhere to, whether they’re internal or externally exposed. As much as possible, we’re codifying those standards within the API hub.”
    The product architect at a software organization said: “I am not alone in making the decisions of writing the schemas. I ensure that once the design is completed, I exchange notations with other product architects and [get] thorough reviews by other colleagues.”

  • Process standardization, which influences best practices across teams. Interviewees explained that SmartBear’s API solutions afforded their teams the ability to design and centralize structured and repeatable processes. As these processes created operational efficiencies, interviewees shared that their teams used this way of working as a model to drive further standardization in other areas of their organizations. The product owner at a financial services organization said: “By using contract testing as an example of what a good standardization opportunity is, we were able to also inspire others around the story and help them leverage the way that we created a managed standardized service, [which had] far-reaching inspirational impacts. This became a blueprint for someone who wanted to create a managed standardized service with monitoring for our provider squad [to show] how our production and pipeline is doing and a health monitor of what is happening for our consumers.”

Flexibility

The value of flexibility is unique to each customer. There are multiple scenarios in which a customer might implement SmartBear’s API solutions and later realize additional uses and business opportunities, including:

  • Improving the time to market for revenue-generating APIs. Forrester’s research shows that those using APIs to deliver new products or push the business in new directions will use a commercial financial model with a direct or indirect monetization strategy.7 Interviewees anticipated releasing revenue-generating APIs to consumers more quickly as their organizations continue to gain API development lifecycle efficiencies. The VP of platform and infrastructure at an IT organization said: “With our quality engineering group being able to start testing that before the code is written and having an understanding of what that API is going to look like, I think our turnaround time on pull requests is going to go down. Our time to market will speed up for those APIs.”

  • Expanding to additional users. Interviewees expressed excitement at offering SmartBear’s API solutions to their full development teams over time to continue to drive the API-first mindset and standardize practices. The product architect at a software organization said: “We wanted to start small and showcase the benefits to our enterprise leadership team. Soon, we are planning to increase the [number of] team members.”

  • Exploring additional functionality. Some interviewees discussed adding additional integrations, while others mentioned specific testing functionality requests like bidirectional testing or AI features. The VP of platform and infrastructure at an IT organization shared: “I expect developers to use HaloAI as a primary path going forward. I would expect it to be used during the design and development of OpenAPI documents.”

  • Providing a consistent platform experience. Interviewees spoke about the benefit of accessing a consistent platform experience for managing multiple SmartBear API solutions. They shared an expectation that a unified platform would drive efficiencies, such as managing user licenses. The director of enterprise architecture at a retail organization said: “I’m excited to see [SmartBear] bring it together as a more consistent platform experience. … I think that it will create value for us as we adopt it more and are able to leverage more of that single platform than a collection of different tools that are loosely connected.”

“There are untapped areas of our organization that we still need to work on. There are still some APIs out there that people didn’t maybe call an API, but that’s what they are. We need to get them into Swagger.”

Flexibility would also be quantified when evaluated as part of a specific project (described in more detail in Total Economic Impact Approach).

  Total costs (risk-adjusted) $99,792 $147,168 $147,168 $147,168 $541,296 $465,777
SmartBear Fees

Evidence and data. Interviewees explained that pricing depended on the number of users and the particular set of SmartBear solutions used. Pricing may vary. Contact SmartBear for additional details.

Modeling and assumptions. For the financial analysis as applied to the composite organization, Forrester assumes:

  • The composite organization has 200 users.

  • The annual Enterprise-tier fee per user is $648. This includes access to Design, Portal, Contract Testing, and Test for all users as well as SSO configuration.

Risks. This cost may vary among organizations depending on:

  • The number of users.

  • The API solutions purchased from SmartBear.

  • Any negotiated discounts.

Results. To account for these risks, Forrester adjusted this cost upward by 5%, yielding a three-year, risk-adjusted total PV (discounted at 10%) of $338,000.

Implementation And Ongoing Management

Evidence and data. Interviewees explained that implementation included uploading design templates, configuring user access and integrations, and training users. They also discussed ongoing management, including managing user permissions, testing out new features and functionalities, and meeting with SmartBear engineers.

  • The director of enterprise architecture at a retail organization said, “We have others outside of that global development team — from architects to business analysts to SMEs and applications or infrastructure or security — that also have access to leverage that single repository for all the documentation.”
    The same interviewee continued said: “We’re probably spending a couple hours a month working through administrative tasks on a product. I think it comes in spikes. We’ve got some opportunity to really clean up our tool access controls. We’re trying to figure out what’s the right level. We want it to be broadly shared and distributed, but we don’t want it to be broadly edited. We’re trying to work through that a little bit and make sure we have the right controls and the right teams set to the right APIs.”

  • The global enterprise architect at a retail organization estimated spending 8 to 10 hours per month on activities related to platform management and administration.

  • The product architect at a software organization said: “Initially, I had the calls with [SmartBear’s] team two times in two weeks. After that, I was familiar with the tool, and I raised a few support tickets for some inquiries. Recently, I had a call with the Swagger team to discuss product enhancements. They are very alert.”

  • The product owner at a financial services organization said: “Because of how easy it is to gain access to the support of SmartBear, [implementation] wouldn’t have been very long. We were tied at the hip with our account person in the beginning. There are so many docs in the SmartBear Academy that we leverage as well.”

  • The VP of platform and infrastructure at an IT organization said, “We use single sign-on and then an integration for pushing the documents out of API Hub into our repositories.”

  • The senior software engineer project lead at an IT organization estimated needing three months of work upfront during implementation to set up the platform for developers.

Modeling and assumptions. For the financial analysis as applied to the composite organization, Forrester assumes:

  • It takes 480 hours for to implement and configure the solution initially.

  • All 200 users receive 3 hours of training.

  • After the initial configuration, the composite dedicates 120 hours annually to ongoing solution management efforts.

  • The fully burdened hourly rate for a developer is $84. The average fully burdened annual salary for a developer is $175,000.

Risks. This cost may vary among organizations depending on:

  • The effort necessary to implement, configure, and manage SmartBear’s API solutions.

  • The amount of training required per user.

Results. To account for these risks, Forrester adjusted this cost upward by 10%, yielding a three-year, risk-adjusted total PV (discounted at 10%) of $127,000.

 Please Note

The financial results calculated in the Benefits and Costs sections can be used to determine the ROI, NPV, and payback period for the composite organization’s investment. Forrester assumes a yearly discount rate of 10% for this analysis.

These risk-adjusted ROI, NPV, and payback period values are determined by applying risk-adjustment factors to the unadjusted results in each Benefit and Cost section.

The initial investment column contains costs incurred at “time 0” or at the beginning of Year 1 that are not discounted. All other cash flows are discounted using the discount rate at the end of the year. PV calculations are calculated for each total cost and benefit estimate. NPV calculations in the summary tables are the sum of the initial investment and the discounted cash flows in each year. Sums and present value calculations of the Total Benefits, Total Costs, and Cash Flow tables may not exactly add up, as some rounding may occur.

From the information provided in the interviews, Forrester constructed a Total Economic Impact™ framework for those organizations considering an investment in SmartBear’s API solutions.

The objective of the framework is to identify the cost, benefit, flexibility, and risk factors that affect the investment decision. Forrester took a multistep approach to evaluate the impact that SmartBear’s API solutions can have on an organization.

Due Diligence

Interviewed SmartBear stakeholders and Forrester analysts to gather data relative to SmartBear’s API solutions.

Interviews

Interviewed six decision-makers at four organizations using SmartBear’s API solutions to obtain data about costs, benefits, and risks.

Composite Organization

Designed a composite organization based on characteristics of the interviewees’ organizations.

Financial Model Framework

Constructed a financial model representative of the interviews using the TEI methodology and risk-adjusted the financial model based on issues and concerns of the interviewees.

Case Study

Employed four fundamental elements of TEI in modeling the investment impact: benefits, costs, flexibility, and risks. Given the increasing sophistication of ROI analyses related to IT investments, Forrester’s TEI methodology provides a complete picture of the total economic impact of purchase decisions. Please see Appendix A for additional information on the TEI methodology.

Total Economic Impact Approach
Benefits

Benefits represent the value the solution delivers to the business. The TEI methodology places equal weight on the measure of benefits and costs, allowing for a full examination of the solution’s effect on the entire organization.

Costs

Costs comprise all expenses necessary to deliver the proposed value, or benefits, of the solution. The methodology captures implementation and ongoing costs associated with the solution.

Flexibility

Flexibility represents the strategic value that can be obtained for some future additional investment building on top of the initial investment already made. The ability to capture that benefit has a PV that can be estimated.

Risks

Risks measure the uncertainty of benefit and cost estimates given: 1) the likelihood that estimates will meet original projections and 2) the likelihood that estimates will be tracked over time. TEI risk factors are based on “triangular distribution.”

Financial Terminology
Present value (PV)

The present or current value of (discounted) cost and benefit estimates given at an interest rate (the discount rate). The PV of costs and benefits feeds into the total NPV of cash flows.

Net present value (NPV)

The present or current value of (discounted) future net cash flows given an interest rate (the discount rate). A positive project NPV normally indicates that the investment should be made unless other projects have higher NPVs.

Return on investment (ROI)

A project’s expected return in percentage terms. ROI is calculated by dividing net benefits (benefits less costs) by costs.

Discount rate

The interest rate used in cash flow analysis to take into account the time value of money. Organizations typically use discount rates between 8% and 16%.

Payback

The breakeven point for an investment. This is the point in time at which net benefits (benefits minus costs) equal initial investment or cost.
