What is a proof of concept: Definition, examples, and template

What Is A Proof Of Concept Definition Examples Template

Building a product is never easy — there are so many ways to do it that it may become overwhelming even to start outlining your idea. Should you start with a prototype, MVP, or a minimum lovable product? The answer is always in your goals, resources, and stage of maturity, of course.

This article aims to guide you through the challenges of developing a product, and decluttering the path to a proof of concept (PoC) while considering limited resources, conflicting priorities, unclear goals, and unanticipated issues.

What does proof of concept (PoC) mean?

A PoC is literally the evidence that your idea is feasible and is based on an experiment or pilot to demonstrate that your idea works — it can be a report document or a literal piece of software. No matter if it’s a design or business proposal, a new stack for an existing product, a feature, or an innovative wearable to be built, the PoC can even be the smallest increment you can think of.

A PoC is meant for when you plan to build a solution and you are not sure of how feasible, expensive, or scalable it is. So, you just build a small component of it to help you understand what it takes to transform this idea into reality — before investing A LOT of money in the real solution.

Proof of concept vs. prototype vs. minimum viable product (MVP)

The PoC is a small part of your project that exists just to see if it works. Once you learn the conditions under which your idea can be implemented, the best next thing to do is to create a prototype.

A prototype is the first design of your actual product. It can be static, like a wireframe, to outline the layout of your entire product and all the flows. Or it can be dynamic, where you design every screen and add some clickable components.

The prototype will help you experience the solution so you can better see how it looks and feels from a visual and/or functional perspective.

The minimum viable product (MVP) is the first version of your product. It’s developed so you can get a first reaction from your users before going big.

In summary, a PoC may help you identify the right technology, the prototype gives you the direction, and the MVP gives you the market reaction before developing a more advanced version.

Ok, explain like I’m five!

Say you want to build a boat for four people stranded on an island. The PoC could be checking what type of boat material will float best near your island (considering the saltiness, currents, and all), the prototype can be an actual raft, and the MVP can be a small, one-person boat for someone to test around:

The end product (the boat) will be a scaled version of the MVP — with some improvements from the person or people who tested the one-person boat, most likely.

Benefits of creating a PoC and best practices to keep in mind

Unsurprisingly, there are several reasons why creating a PoC is helpful.

Saves money and time

PoCs help you identify the right solution to move forward with. No matter if you build a functional, visual, or experimental PoC, the effort will be low. In return, you will know the necessary resources to build the entire solution, you’ll uncover uncertainties, and it’ll help you focus on your goals.

Helps you shape your forward-thinking into reality

PoCs will make you consider logistics ahead of time, so you can streamline your work and advance more efficiently to the next step.

PoCs give you a strong start with investors. If an idea is too big for the world to grasp easily and you need the public or your investors’ trust, use a PoC to showcase an overview of the risks and rewards you can foresee. The chances of success will be far higher than going in front of them with a simple pitch deck.

Identify and mitigate roadblocks

Sometimes, a PoC will demonstrate that your idea is feasible but super expensive. Or extremely difficult to put in place. It can be a matter of scaled manufacturing, rare technology, or any other logistic problem. A PoC will help you prepare for the challenges ahead or pivot your idea (and build another PoC).

On the other hand, PoCs are not meant to be re-used or exposed to customers, and it is definitely not scalable. Once you build a PoC, its goal is achieved.

6 steps to writing a proof of concept

A successful proof of concept should always have the following elements: clear goals, defined metrics, realistic assumptions, and an appropriate scope.

And before going through the steps of developing (ideation, defining requirements, building a prototype, testing, and validation), you first have to write the proof of concept.

1. Problem definition and target audience identification

It is crucial to define the problem you want to find the solution for and the audience (end-user, influencer, and decision-makers). This will define if your PoC will be functional, visual, or experimental.

2. Identify necessary stakeholders

Ensure that everyone’s interests and needs are considered and outline all the contributors needed for the creation process.

3. List available resources

Jot down all the available resources you have. This includes your team and capabilities, production materials or partners, budget limitations, and the plan for the PoC.

4. Define success

To evaluate the PoC effectiveness, you need to define the exact use case you want to cover and specific metrics to look at. The metrics will help you figure out if your idea is meeting the idea of the use case. A few examples of metrics to look at are:

  • Return on investment (ROI) or cost-effectiveness: this metric help you determine whether the PoC is financially viable. Will it cost too much money to scale up? Should it be discontinued? Is it cost-effective to develop and implement? To measure cost-effectiveness, you should consider all development costs, operational costs, and potential savings that your new solution can provide
  • Functionality and integration: these metrics work through user feedback, testing the features, and demonstrating the feasibility of integrating the solution with existing systems (in terms of compatibility, amount of time needed, and resources)
  • Business impact: this can be measured by assessing the potential benefits that the solution can provide while considering the impact on business processes, operations, and competitive advantage5.

5. Write down the PoC scope

People tend to start with a PoC, and soon enough it becomes a prototype or an MVP. Write down your scope to ensure that the outcome will be achievable and, most importantly, relevant to the problem being addressed.

6. Create a timeline and next steps

Finally, record a realistic timeline and the context of the PoC, including the start date, process, and next steps based on the outcome. For example, write down if the idea is not feasible if it is feasible but if you lack certain resources, if the idea is feasible and within the success definition, etc.

Proof of concept template

To make things easy, I created a PoC template, aka a creation canvas, for you to download off of Google Sheets. The template comes with an example as well.

With this template, you can easily organize your PoC goals and information to ensure an impactful outcome.

Conclusion and key takeaways

Proofs of concepts (PoCs) exist to help you know if an idea or solution is feasible in certain conditions. Do not forget that it’s never meant to be used for user-facing interactions, nor to build on top of — PoCs are very unstable, very much like an experiment.

Building the PoC will guide you forward, and you can better plan your time, resources, risk mitigation assessments, and a competitive advantage for the next iterations.

Writing a PoC helps you stay focused on what you want to achieve. It frames the problem, scope and expectation, audience, stakeholders, resources, success definition, and timeline.
