A proof of concept is a crucial tool to test the feasibility of an idea, product, or technology in an early stage. It’s a strategic way to reduce risks, justify investments, and convince stakeholders.
A proof of concept (POC) is a small-scale implementation of an idea or technology aimed at proving its technical and/or functional feasibility. Unlike a full product or prototype, the focus is on answering the question: can this work?
You typically use a POC to remove uncertainties before committing time and money to further development. Think of new features, integrations, technologies, or even entire business models.
A POC is especially useful when:
You’re dealing with technical uncertainties.
There’s no internal buy-in yet from the team or stakeholders.
You want quick feedback from experts or users without building something large.
You want to prove that your solution actually solves a problem.
This means no months-long development tracks based on assumptions, but short, focused testing to validate your direction early on.
A proof of concept is often confused with terms like prototype, pilot, or MVP. While they’re all part of product development, each serves a different purpose. It’s important to understand these differences so you can apply the right method at the right time.
A POC focuses on feasibility. The main question is: can this technically or functionally work? It’s usually internal, small-scale, and not intended for end-users.
Example: you want to test whether integration with an external API is possible. You create a simple setup that only validates that specific part.
A prototype is a visual or functional representation of the product. The goal here is to evaluate user experience and design, not the technical feasibility. A prototype is typically used to gather feedback on UI and interaction flow.
Example: you build a clickable design in Figma or a front-end without a working backend to demonstrate the idea to stakeholders.
A pilot is a limited real-world rollout, frequently involving actual users. The purpose is to test the product in a real environment before a full-scale launch.
Example: a small group of customers uses an early version of your software to identify bugs, usage patterns, and reactions.
An MVP is a basic first version of your product that already delivers value to real users. It includes only the core features needed to gather feedback and learn from real market behavior.
Example: a working app with only the essential function to test demand.
Setting up a proof of concept requires a structured approach. Below is a clear step-by-step guide to help you make the right decisions and guide your team efficiently.
Clearly formulate the problem your POC aims to address. Focus on one specific question, such as:
Is this technology compatible with our existing infrastructure?
Or: Can we build this functionality within our current architecture?
A sharp problem definition prevents your POC from becoming too broad or vague.
Describe what is in scope and out of scope. Focus solely on the part you want to validate. Limit the number of variables so your results are easy to interpret.
Scope example: We’re only testing if the AI model can auto-tag raw text – the user interface is out of scope.
What people, tools, data, and time do you need? Define who should be involved: developers, data scientists, security specialists, etc. Also consider technical conditions such as test environments and API access.
What defines a successful outcome? Set objective criteria in advance, such as:
Response time < 500 ms
95% accuracy in output
Successful API connection without errors
Make sure all stakeholders are aligned on these criteria.
Don’t make it too tight, but don’t overplan either. A POC is not a long-term project. Keep it short: typically, 1 to 3 weeks is enough. Identify important review moments as well.
Create the simplest possible implementation that can test your hypothesis. It doesn’t need to look good, but it must functionally prove whether the idea works. Document how the demo works and what you're observing.
Share your demo internally with key stakeholders: developers, security, management, business owners. Ask for their input based on the success criteria. Collect both technical and business-related feedback.
Compare results against your predefined criteria. What worked? What didn’t? Is further development justified, or should the idea be adjusted?
A well-executed POC enables data-driven decision-making, even if the outcome is negative.
If the POC is successful, work with your team to define the logical next step: a prototype, MVP, or full implementation. Turn your findings into a clear roadmap, including risks and dependencies.
A proof of concept is used across various industries to minimize risk and validate innovation. For product owners and development teams, it’s especially valuable to test technical assumptions before investing significant development time. Below are some common use cases.
In software projects, a proof of concept is typically used to test technical feasibility. Examples include:
Integrating a new technology (such as an AI model or external API).
Connecting systems with different architectures.
Estimating performance or scalability.
It’s the ideal way to back technical decisions with evidence. It helps ensure the team doesn’t build based on assumptions or guesswork.
A POC helps validate new business models or product ideas in practice. Here, the focus is not only on technology but also on market validation:
Would customers actually use this?
Do internal stakeholders see the value?
Can this save costs or streamline operations?
You might, for example, run an internal POC for a new customer portal or an automated reporting system.
In security, a POC can show whether a specific solution meets the organization’s security standards. For instance:
Testing encryption methods
Using identity providers like OAuth or SSO
Evaluating data leak prevention or authorization controls
A successful POC in a security context is often essential for building trust and gaining compliance approval.
For physical products or embedded systems, a POC often checks if a design is technically feasible. Think of:
A sensor that collects data and transmits wirelessly
Combining hardware and software in IoT solutions
While this is a bit further removed from software development, the principles remain the same: you want to know if something can work.
A proof of concept isn’t just a nice-to-have, it’s a critical tool in the early stages of product development. It offers strategic benefits from both a technical and business perspective.
A POC helps identify risks early on. It prevents you from spending months working on something that turns out to be unfeasible. Think of integrations that aren’t possible, technical limitations you initially overlooked, or assumptions that don’t hold up.
By uncovering these kinds of roadblocks early, you save time and money eventually.
When working with innovative ideas or proposing major changes, convincing stakeholders can be a challenge. A well-executed POC helps eliminate doubts and build support.
A working demo often says more than a pitch deck. It indicates that the idea isn’t just ambitious, it’s actually feasible.
A POC requires relatively few resources and little time, but it helps avoid expensive mistakes later in the process. It gives you clarity up front, instead of discovering critical issues halfway through development.
This is especially valuable for teams with limited budgets or tight deadlines.
A POC answers the technical questions that are crucial for moving forward. Does this API work as expected? Is our current infrastructure compatible? How does the system handle pressure?
Without a POC, it’s guesswork. With a POC, you have evidence.
A proof of concept can deliver great value, but only when executed properly. In practice, many POCs fail due to incorrect assumptions or poor planning. Below are the most common pitfalls, and how you can avoid them.
One of the most common mistakes is trying to prove too much at once. This often leads to unclear goals and wasted effort on irrelevant details. Keep the scope narrow and focused on one central question. Anything that doesn’t directly contribute to testing that question should be left out.
If you don’t define what success looks like upfront, your team won’t know what to aim for. It also makes it harder to evaluate outcomes objectively. Set measurable and realistic success criteria. Make sure all stakeholders agree on them before you begin.
A proof of concept is not a final goal. Yet often, the results end up sitting in a drawer. Nothing is done with the findings, and the POC is never followed by a prototype or MVP. Always plan what you’ll do with the results before you start the POC.
Sometimes stakeholders expect a POC to look like a finished product or be tested by end users. This leads to unrealistic expectations and unnecessary pressure on the development team. Make sure everyone understands what a POC is and what it isn’t.
A proof of concept isn’t a luxury, it’s a smart first step for any development team looking to minimize risk before making serious investments. By validating the feasibility of your idea early on, you avoid costly mistakes, build internal support faster, and move forward with confidence.
A proof of concept includes a clear problem definition, a defined scope, required resources, measurable success criteria, a functional demo, and an evaluation plan with next steps.
A POC tests whether an idea is technically or functionally feasible through a limited, controlled implementation that is evaluated against predefined success criteria.
A POC (proof of concept) tests feasibility within a specific context. A POP (proof of principle) demonstrates that a technical idea can work in theory, often without considering practical application or integration.
