When to Use a Proof of Concept and When to Use a Prototype: Making the Right Choice

Can bringing the concept behind your app to life begin just with a basic idea, or does it require careful planning and a targeted understanding of the needs and expectations of your target market?

The latter is the case, which means you’re also likely already aware of the two vital tools that can make app development significantly more successful – the Proof of Concept (POC) and the Prototype. But how do you know which one you need and when to use them?

Read the full blog post Proof of Concept or Prototype – Which one do you need? And learn more about how to make the most of these essential software/app development tools.

In this blog post, we’ll first understand what a POC is, how it differs from a prototype, and when you should utilize each during the development of your app.

Unveiling the Purpose of a Proof of Concept (POC)

  • Defining the Purpose: A Proof of Concept (POC) is an experimental, scaled-down version of your idea to answer the question, “Can it be built?” It’s typically focused on validating the technical feasibility of your app idea before you spend extensive time and resources.
  • Prototype Demystified: Discover how companies are using prototypes to reduce the likelihood they’ll have to overhaul parts of their app. Prototypes can also serve as the initial iteration of your beta, as you can choose the features you want from the app and incorporate them into the prototype.
  • Unveil What Your App Brings to the Table: You can begin conversations with potential partners and customers to secure additional support or data by developing a prototype and having early users play around with it. The excitement you generate lets you float new features and applications that don’t exist today.

Ecosystem Expansion

  • Understanding Your Ecosystem: From Google to Amazon to Facebook, nearly every tech giant now has software they make available to developers. Developers can build on their open platforms. You download the software, build previews, and use it in a broad consumer context.
  • Leverage, Leverage, Leverage: Are you launching your app in a professional setting or to consumers? Do you know all you need to about a new platform, or do you have no idea why or how it’s exploding? The only way to navigate the complexities of a platform is to leverage the experience someone else has accumulated.
  • Win/Win Ecosystem Expansion: A no-code, flexible development tool allows the team to prototype and test an app with other internal users or external customers before you launch. Not only have you developed an app that can be deployed immediately after your announcement, you’ve also gained insight into what users need and have optimized the product accordingly.
  • Importance of User Feedback: Discover how prototyping aids in gathering user feedback, ensuring that you are building an app that meets the needs and expectations of your target audience. Prototyping allows you to advance through the stages of development with lower overhead, and the user gets to see the concept and offer feedback on the idea, as well as the usability of the app. With prototypes, changes can be made to refine the features and design of the end product, and it provides validation and momentum to your development project.
  • Showcasing Potential: Learn how prototypes generate excitement among stakeholders, investors, and potential users by presenting a tangible vision of the final product. A prototype provides a living, breathing snapshot of your application’s potential. This can wow potential investors and stakeholders and give you the leverage you need to secure more investment or that group of users to become the most prominent advocates of your app.

Making the Right Choice: Factors to Consider

App Complexity

Analyze the complexity of your app idea and determine if a POC is necessary to overcome any technical hurdles before proceeding to prototype development. If your app concept involves complex integrations and non-standard technologies, you may want to consider building a POC to test feasibility.

Market Validation

Evaluate the need for market validation to determine if a POC or prototype is more suitable for testing user demand and potential profitability. A POC can be a good bet if the app concept is geared toward new markets or technologies. However, if you are targeting an existing market and looking for the best presentation to present to potential users, a prototype will be a better option.

Available Resources

Consider the availability of resources such as time, budget, and expertise when deciding between a POC and a prototype. A POC is less expensive and can give you an idea of the feasibility of the concept. In contrast, at a more substantial initial cost, a prototype can test assumptions on characteristics such as usability and functionality.

Best Practices for Successful Implementation

Focused Scope and Key Objectives: Define a narrow scope for your POC/ or prototype so that you test and validate core functionalities efficiently; if your scope ends up being too high level, you may lose your focus and not have a clear direction. The solution is to have multiple narrow and more targeted POC/prototypes to explore specific aspects of your idea.

Leveraging Prototyping Tools and Techniques: Research and experiment with various rapid prototyping tools and techniques to streamline your process and gain meaningful insights. Recently, there has been an influx of tools expressly set up to enhance and speed up your prototyping. This helps save you time and resources and the costly cycle of going back to modifying models from the production line.

 Iterative Feedback Loops: Establish a well-oiled feedback loop with key stakeholders to tackle challenges, refine concepts, and make informed decisions. Ensure that potential users and testers continuously give input from the moment – heck even before – you start prototyping, all the way to when you “go live”. This helps ensure that every iteration of your solution puts something more valuable out.


The Proof of Concept vs. prototype decision is an integral step in the journey for your app idea. When you understand the background and benefits of both paths, you can make an educated decision for your particular project needs. A well-executed POC can save you from potential risks, and a prototype can guide you to a place where you’re building an app that users and investors will love. Recognizing the power of these tools and knowing when to employ them will be the difference between your app and your competitors.

Picking the proper development strategy in a field that changes as rapidly as mobile apps is essential for success. When you leverage the potential of a Proof of Concept and weigh the advantages of a Prototype, you’ll have an understanding that gives you the insight to create apps that innovate, engage, and perform.

Remember that you can use both POCs and prototypes in the same development cycle (this can help refine the overall functionality and performance of your app) – so explore the best balance between prototyping and POCs.
