A proof of concept (POC) is a realization of a certain method or idea in order to demonstrate its feasibility and verify that a concept or theory has practical potential. In other words, a proof of concept is a way to validate if a product, feature, or idea is viable and warrants further investment and development.
A POC is focused on testing a discrete concept, feature or application. It is a small experimental project that is developed quickly with minimal resources to provide evidence that the idea can work. It allows you to test theories and assumptions made during the planning phase of product development.
A proof of concept is different from a prototype in that the POC focuses on a very narrow piece rather than the entire product. It may only include core features rather than every planned capability. The goal is to efficiently evaluate feasibility, not create a scaled down version of the end product.
A proof of concept also differs from a minimum viable product (MVP). While an MVP represents a version of the final product with just enough features to be usable by early customers, a POC has no consideration of the user experience. The POC is not intended to be released to real customers, just to prove the concept works.
So in summary, a proof of concept demonstrates the feasibility of an idea, a prototype models the end product, and an MVP represents a commercially viable product. POCs help validate assumptions and approaches before significant development resources are committed.
A proof of concept serves several important purposes in the product development process. Here are some of the main reasons organizations develop proof of concepts:
One of the primary reasons to create a proof of concept is to validate the capabilities and functionality of a proposed product or technology. By building an early version, teams can test and demonstrate that the key features are possible to develop. This validation gives stakeholders confidence that the product idea is feasible before committing more resources to the project.
In addition to validating the product itself, a proof of concept allows organizations to test assumptions about the business model. This includes things like target customers, pricing models, distribution channels, and value propositions. Teams can use the proof of concept to get early feedback on business assumptions before finalizing plans.
Developing a proof of concept is a way to assess the feasibility of a product idea. There may be technical challenges or resource constraints that make an idea infeasible. Building an early prototype can uncover these potential issues to determine if the idea is viable or needs adjustment. Demonstrating feasibility can also help secure buy-in from stakeholders.
For startups and new product ideas, a proof of concept can be instrumental in securing funding from investors. Rather than investing in an unproven idea, investors want to see evidence that the product will work as envisioned. An impressive proof of concept can demonstrate this potential and give investors more confidence in providing funding.
A proof of concept offers several key benefits for product teams and organizations:
One of the most valuable aspects of a proof of concept is that it allows you to validate whether there is product-market fit between your proposed solution and target users. By putting an early version in front of real users, you can understand if it solves their needs and pain points. The feedback from testing a POC provides concrete data on whether the product concept resonates.
Creating a proof of concept forces product teams to translate an idea into something tangible. This helps align stakeholders on what the product is and how it will work. A POC serves as a demonstration of the vision and strategy. The exercise of building it often uncovers assumptions, unknowns, and differences in understanding that can then be addressed.
Proofs of concept minimize risk by validating concepts before committing significant time and money to full development. Building the minimum version first acts as an experiment that generates data and learning. This evidence then informs the decision of whether to proceed with the product or pivot the concept. POCs allow validation without overinvesting upfront.
Launching a proof of concept gets direct user feedback at the earliest possible stage. By putting it in front of target users, teams can understand reactions, pain points, and desires. This insight is far more useful when integrated at the beginning rather than after already launching the product. POCs enable user research, feedback, and collaboration at the start of the development process.
A proof of concept, prototype, and minimum viable product (MVP) are similar in that they are early stage versions of a product, but they differ in their purpose, level of detail, and functionality.
A proof of concept aims to demonstrate the feasibility and validity of an idea or theory. It is focused on answering questions around "can this work?" and "should we proceed with this idea?". In contrast, a prototype is intended to test functionality, usability, and design. An MVP is a rudimentary version of the product that can be tested for market viability.
A proof of concept provides a basic representation of the core idea, with minimal features and design elements. It is not concerned with aesthetics or user experience. Prototypes exhibit moderate design details, enough to demonstrate product workflow and simulate user interactions. MVPs contain the minimal set of features that can fulfill the product's core purpose and function.
The functionality in a proof of concept is limited to proving technical capabilities and possibilities. A prototype offers partial functionality that conveys the essence of the product experience. An MVP provides complete, albeit basic, functioning that solves a core customer problem.
A proof of concept makes sense in the very early ideation stages, before significant time and resources have been invested in full development. Building a prototype is appropriate after initial market validation, when the priority becomes fine-tuning the user experience. An MVP should be pursued when there is confidence in the product direction and sufficient feedback to proceed to a basic functioning version.
A proof of concept should demonstrate the key features, capabilities, design and basic analytics tracking of your proposed product or service. Here are some of the main elements to include:
The POC should have just enough of these elements to demonstrate the viability and benefits of the overall idea or technology. Keep it focused on a limited scope proving essential functionality.
The proof of concept document is a detailed plan that outlines how you will build and test the proof of concept. Here are the key sections to include:
The executive summary provides a high-level overview of the key points covered in the document. It should briefly explain:
Keep this section short, around 1-2 paragraphs. Focus on piquing interest in your idea.
The product description provides details on the product, technology, or idea you want to prove. Explain:
Make sure to outline the scope of what will be covered in the proof of concept.
This section forms the bulk of the document. Provide a step-by-step explanation of how you will build and test the proof of concept. Cover:
Go deep into the technical specifics here. Document all requirements for replicating your work.
Define what success looks like. Provide quantifiable targets that determine whether the proof of concept achieves its goals, such as:
Establishing clear success criteria is crucial for validating the viability of your idea.
The proof of concept document provides a blueprint for executing your plan. Being comprehensive and detailed will ensure alignment and reduce surprises during implementation.
The actual building of the proof of concept involves assembling the right team and resources to design, develop, and test it. Here are some key steps:
Identify the key roles needed to build the POC such as product manager, developers, designers, testers, etc. Include both technical and business experts who understand the goals and can determine if the POC achieves them. Keep the core team small and focused.
Clearly define the boundaries of the POC such as the specific features, user stories, or use cases to be tested. Determine the minimum viable product that proves the concept. Avoid scope creep by aligning on the exact problem to be solved.
Give the team a tight timeline, usually 2-3 weeks up to 3 months max. Constrain the budget as well to keep the team focused on rapidly validating the core concept without getting distracted by extras.
Select the fastest and most appropriate technology to build the POC whether that's coding languages like Python or JavaScript, low-code platforms, or other tools. Balance speed with demonstrating the production-ready technology.
With the defined scope, timeline, and technology, the team can start building the proof of concept. Use agile development methods for rapid iteration and feedback. The end result should be a working prototype that demonstrates the core functionality and technology viability.
Once you've built your proof of concept, the next step is to test and validate it. This involves clearly defining metrics for success, conducting user testing, gathering feedback, and critically assessing overall viability.
First, determine what metrics you'll use to evaluate whether your proof of concept achieves its goals. These will vary based on your specific project, but common metrics include:
Set specific, measurable targets for each metric that indicate success.
Next, test your proof of concept with real users. Recruit a small set of people from your target audience to interact with the concept and observe their experience. Ask them to complete realistic tasks and note where they succeed or struggle.
User testing reveals pain points and flaws you can address before expending more resources on full development. It also gives insight into required revisions to make the concept truly usable and valuable.
Collect qualitative feedback by having testers complete surveys, interviews, or focus groups about their experience. Gather opinions on the concept's usefulness, convenience, likability, and more.
Listen closely to the language users employ to describe the concept. Their word choices often indicate underlying perceptions.
Finally, compile all your test results and feedback. Analyze whether your proof of concept realistically achieves its goals and merits investing in further development.
If it falls short, determine what specifically makes it inadequate. Then decide whether those weaknesses necessitate scrapping the concept or if targeted changes could sufficiently improve its viability.
Use the lessons from your proof of concept testing to inform smarter product decisions. Validated successes demonstrate customers want what you're building.
After completing the proof of concept, the next step is to decide whether to move forward with developing the full product or service, or to pivot and change directions. The proof of concept provides key insights and learnings to inform this decision.
Analyze the results from testing the proof of concept. Did it validate the assumptions and feasibility of the idea? Was the target audience receptive and enthusiastic? Did it uncover any major issues or risks? Weigh the overall benefits against the costs and effort required for further development. Determine if it's worthwhile to proceed to the next phase or if it's better to go back to the drawing board.
If deciding to move forward, outline a development roadmap and project plan. Break down the product/service into distinct components and milestones. Estimate the resources, budget, and timeline required to complete each stage. Define specific goals, deliverables, and success metrics. Planning out the full lifecycle early on will help keep the project on track.
Based on the project plan, determine what skills and personnel will be needed to execute each phase of development. This may require hiring more developers, designers, project managers, etc. Onboard new team members early so they can provide input on the plan.
Additional funding may be necessary to take the concept to full production. Determine how much is needed to complete development and launch. Identify potential investors or funding sources and pitch to them based on the promising proof of concept results. The proof of concept provides evidence of feasibility that can help secure further financial backing.
The proof of concept provides the foundation to determine next steps. Carefully evaluate whether to proceed further, change direction, or integrate lessons learned into future projects. By outlining detailed plans and bringing on resources before building the complete product, teams can capitalize on the momentum from the proof of concept.
A proof of concept document should contain the key information needed to evaluate the feasibility of an idea. Here are the key sections to include:

Below is an abbreviated example of a proof of concept document:
This proof of concept aims to test the feasibility of developing an automated inventory tracking system using RFID technology to track inventory levels in real time. The goal is to demonstrate that RFID can accurately track inventory movement and provide real-time visibility into inventory counts across our warehouse locations.
The automated system is expected to reduce the time spent on manual counts by 80% while improving accuracy of inventory tracking. If successful, this concept would provide the capability needed to optimize our inventory management across locations.
This POC will focus solely on the automated tracking of inventory movement in and out of the warehouse using RFID. Specific functionality includes:
The web app dashboard will be built using Django and PostgreSQL. RFID hardware will be set up in a simulated warehouse environment to test tracking of sample products tagged with RFID labels.
Success is defined as tracking inventory movement with 95%+ accuracy. RFID tracking accuracy will be measured by comparing system counts vs. manual counts after various simulated workflows:
If successful with 95%+ accuracy, we recommend moving forward with developing an MVP inventory management system leveraging RFID technology. Next steps would be to refine requirements, evaluate compatible RFID hardware, and assess needs for integration with existing warehouse systems.
If accuracy is below 95%, we will re-evaluate technical approach and suitability of RFID for this application. Alternative technologies like barcodes and weight sensors may be more viable.
