Proof of concepts are used during various stages of software development. They can be used as part of requirements gathering or they may also form a key element of the project itself.
In this article we will explore all three types of proofs of concept, from their importance to when exactly they should be created. We'll look at some best practices which should help you on your way!
The term "proof of concept" (POC) has been around since 1980s but its meaning was different then. It was mainly associated with prototypes, where people would build something that could show off the features of a new technology but usually without any real functionality. This type of prototype still exists today and is sometimes called a "functional mockup". However, over time the word began to take on more specific meanings. In the context of software development, a POC can mean anything ranging from a simple test application to full blown user interface. The main use case for such work is to ensure that everything works correctly before proceeding further into actual development.
This approach is quite common within agile methodologies like Scrum and XP, where teams have short sprint cycles that require constant iteration throughout the process. A POC allows developers to quickly verify whether the solution meets the client's needs while reducing risk by providing early feedback. While creating a POC does not guarantee success, it does provide valuable input and helps reduce the amount of wasted effort later down the line.
A good place to start if you want to try out POC techniques is with Microsoft Project. You can find many templates online for building functional mockups and even complete applications. These include tools like Visual Studio Code and Power Automate, both of which allow users to perform automated tasks via APIs.
As well as being useful for internal projects, a POC can also act as a demo for clients who might consider hiring your services. If you're aiming to secure funding, a POC will give them a better understanding of what your final product looks like.
When working on products, one of the most important things you need to get right is the overall design. Your customers will only buy your product if they believe it solves their problem - so making sure it feels intuitively designed is vital. Proof of concept offers another option to validate your ideas prior to starting production.
Instead of spending money developing a fully-fledged version of your product, you can instead put together a quick demonstration using existing technologies and frameworks. You don't necessarily need to stick to the same tech stack as your final product, either. For instance, you could demonstrate your idea using React components alongside HTML/CSS for styling.
Once you've built up enough confidence about the basic structure of your app, you can begin putting together a demo that showcases all of its capabilities. Not only will it let potential investors see what the finished product will look like, but it will also give you the opportunity to collect feedback from anyone interested in helping develop your product.

It doesn't matter what kind of product you're trying to develop, there will always be some sort of proofing stage that precedes release. One of those steps involves creating a POC, often referred to as "a minimum viable product" (MVP).
An MVP is just a small sample of your intended output, ideally consisting of core functions that show the value of your idea. Instead of attempting to implement every aspect of your product, you focus on delivering a minimal set of features that prove your idea is worth pursuing.
You can use a variety of methods to determine which parts of your POC are necessary. Some companies will run usability tests with potential users, while others rely on market research conducted through surveys. Whatever methodology you choose, make sure you involve stakeholders in order to avoid wasting resources on unnecessary features.
However, remember that an MVP isn't meant to represent your final product. Don’t expect to ship your MVP to your beta testers straight away - just because you think it works now doesn't mean everyone else agrees. Even though your goal is to deliver a stable, usable product, you should keep iterating until you reach that point.
To learn more about MVP, read our guide to building an MVP. There you'll find advice on defining your target audience, deciding which metrics to track, and choosing how long it takes to launch your MVP. Finally, we cover why you shouldn't rush your MVP into production and how to handle bugs once your team starts working on your next feature.
While proof of concept is commonly applied to IT development, it can also apply to other industries. Often businesses must go through several iterations of testing before reaching a final product. During each phase, they must come up with ways to evaluate whether changes made to their product improve performance.
For example, let's say a company wants to sell their wares online. When launching their website, they'll likely conduct multiple rounds of testing to gauge visitor behaviour and identify areas for improvement. At no point should they stop improving based on these results alone. So rather than focusing on the end result, they must constantly assess progress towards achieving their goals.
By applying the same principles to their product development, companies can make steady improvements that lead to higher revenues. This means having a clear vision of what their ultimate product should look like, along with a plan on how to achieve it.

Here you'll discover how to define your purpose, scope your objectives, and decide how much data to gather. Once you've got a solid grasp of the basics, you can move onto planning the rest of your strategy.
Software testing plays a crucial role in verifying that your developed code behaves properly. But it goes beyond simply checking that individual lines of code compile successfully. To truly ensure quality, you must thoroughly investigate the entire system.
That's where a proof of concept comes in. Rather than relying solely on unit tests, you can use a POC to simulate realistic scenarios involving multiple users accessing the site simultaneously. By doing this, you can gain insight into how your web page performs under heavy load conditions.
During this exercise, you'll observe how visitors interact with your site and how fast they navigate between pages. From here, you can adjust your coding accordingly to prevent bottlenecks or slowdowns. And by simulating real traffic patterns, you'll save yourself hours of manual regression testing.
Because writing a proper POC requires careful consideration, it's essential to enlist the help of someone experienced in performing these kinds of exercises. Otherwise, you won't know what to measure, nor how to interpret the results. Also, consider outsourcing your POC to a specialist firm like WebTesters. They offer a wide range of services including UI automation, browser compatibility checks, and stress testing.

Plus, you'll receive expert guidance on how to automate repetitive tasks and streamline workflow management.
UX stands for User Experience, and encompasses the entirety of a person's interaction with a digital device. That means it includes the interface, navigation, content, and interactions among all elements. Therefore, UX designers play a major role in ensuring your website is accessible and intuitive.
But a great deal of your job remains invisible. After all, how easy is it for a user to understand a piece of text, when the font size is too large or the color scheme is hard to distinguish? All of this makes up the foundation of your user experience, and it's difficult to test unless you actually have someone interacting with your website.
So what's the alternative? Well, proof of concept is perfect for proving your designs are effective across platforms. For instance, you can use a POC to test out a range of layouts and colours. Then you can compare the resulting statistics against the baseline values determined by your analytics tool.
This allows you to spot discrepancies between the two and determine whether your design choices were correct. Of course, you don't need to limit yourself to websites. Any digital platform can benefit from a POC, including mobile apps, desktop programs, social media profiles, eCommerce sites, and so forth.

When starting up any new project or developing an existing product there are many things that need to be done before the initial stages can begin. These include design, architecture, documentation, requirements gathering, usability analysis etc. However, if one area needs more attention than others then this is where Proof Of Concept (POC) comes into play.
A Proof Of Concept (POC) is used by developers when they want to test their ideas out on a small scale with limited resources. It’s also commonly known as a prototype because it looks like a real version of something but isn't quite finished yet. This way, both the developer and the client can see whether the software works well enough to move forward.
So how does one go about creating a POC? What should they look at while doing so? And why would someone bother anyway? Let's find out!
The best place to start when looking at a POC is from within a company. A good example here could be Microsoft itself which has had several POCs over the years including WordPerfect 6.0 Beta 1, Word 97, Excel 95 and Outlook Express 2.0. In fact, back in 1996, Bill Gates himself was using Office 4.5 Beta 3 internally and even went as far as writing emails in his own personal email account.
While we may not have seen a fully fledged version of Windows Vista until 2008, its predecessor XP saw a lot of use during its early days – especially due to the release of Internet Explorer 7.0 beta. So, while these aren’t exactly major releases, they did show off Microsoft’s ability to deliver products quickly and efficiently through internal tests.
These types of POCs have been shown time after time to work extremely effectively and allow companies to get ahead of competitors. As such, it seems only logical that other businesses will try similar methods. After all, who doesn’t love getting ahead of the competition?
Now let's take a look at some ways that a POC can help make sure a project gets started successfully and with little effort wasted.
1. The Client Is Involved From Day One
There are two main benefits of involving clients from day one. Firstly, it ensures that everyone knows what is going on. There is no ambiguity between them since they know exactly what is being worked on. Secondly, it allows them to provide feedback along the way which helps improve the project and keep it moving in the right direction.
2. Scope Is Set Early On
One thing that often happens during a POC is scope creep. Developers tend to add features to a project without checking whether they actually fit the brief. By setting clear expectations from the outset, this problem is prevented entirely. Instead, the project starts off with everything needed to complete the task already included.
3. Test Cases Are Written Before Code Starts To Be Created
This point ties into the previous one as part of making sure that nothing slips through the cracks is by having written down all possible scenarios beforehand. Not only does this ensure that bugs don’t arise once code begins to be developed, but it also prevents anything else from happening either.
4. Time Frame Is Short Enough For All Tests To Run
Another benefit of working with a short timeline is that there is less risk involved. If a POC takes longer than expected then there is always the chance that the whole process ends up being scrapped. However, if it runs much shorter then there is still plenty of time to fix issues found later on.
Of course, the opposite is true too. Too long of a timeframe means that problems might never surface at all. While this isn't necessarily bad, it could mean that important information is missed. Again, however, this can easily be fixed if necessary.
5. Everything Checks Out With Other Teams Working Together
Working together with multiple teams throughout the entire process is another great benefit of a POC. Even though each team focuses on different aspects of the project, they all meet and talk regularly to ensure that progress is made smoothly. Each person feels valued and appreciated for their contribution.
6. Feedback Meets Expectations Quickly
If a POC turns out badly, it can cause a lot of stress among those involved. However, by keeping communication open, the chances of this occurring are greatly reduced. Furthermore, if problems come to light, they can be addressed immediately rather than allowing them to build up.
7. Development Costs Are Low
Lastly, low-cost development is achieved through outsourcing certain tasks. Since most people have experience in just one specific field, they can offer expertise in areas they are familiar with which saves money overall. Also, as mentioned above, POCs are usually very quick to develop compared to full versions of software.
8. A Good Idea Prevents Bad Ideas
Since a POC is built around a single purpose, it forces developers to focus on delivering quality results instead of trying to achieve too much at once. Therefore, it provides a level playing ground for everyone involved to compete against one another.
9. No Money Has Been Spent Yet
As stated earlier, a POC requires minimal investment from everyone involved. Thus, while there may be costs associated with hiring extra staff, these won't be incurred straight away. Even better, the cost of rework caused by mistakes will be avoided completely thanks to a lack of commitment.
10. New Features Can Be Added Later Down The Line
Finally, a POC gives the opportunity to introduce new features later on. Although this sounds obvious, it is worth mentioning again as it shows how valuable POCs are. Often times, they prove to be invaluable when deciding whether additional functionality should be added to a product.
11. Everyone Knows Exactly Where They Stand
In conclusion, a POC is beneficial for anyone working on a project as it allows everyone to understand how their role fits into the bigger picture. Additionally, it keeps everyone accountable towards achieving the desired goals. Finally, since it is easy to implement, everyone involved can contribute meaningfully.
12. Results Are Seen Immediately
Although this is probably self-explanatory, a POC can also save hours of frustration when dealing with stakeholders. When showing a completed result to someone, it is easier to explain what is taking place without needing to spend ages explaining every detail.
13. Quality Assurance Tasks Aren't Forgotten
With a POC, QA tasks are handled effortlessly. Instead of spending countless hours searching for defects, they simply run through the steps required to verify the final product.
14. Little Risk Is Taken
Perhaps the biggest reason why a POC is useful is that it reduces the amount of risk taken. Because it is relatively simple to put together, it minimizes the number of potential flaws that could occur.
15. POCs Help Keep Projects Moving Forward
By providing a method for developers to test their ideas, a POC proves effective in helping keep a project moving forwards. Without it, there is a high likelihood that it wouldn’t ever reach completion.
16. Communication During Testing Ensures That Nothing Goes Wrong
Communication is vital during POCs. Both parties must communicate clearly and openly so that misunderstandings are kept to a minimum. This can prevent problems arising further down the line.
17. POCs Save Time & Money
Not only does a POC reduce the amount of time spent on testing, it also saves money. Unlike full versions of software, POCs are generally cheaper to produce.
18. POCs Allow Clients To See Things At An Earlier Stage
Because POCs require a smaller budget to produce, they give customers access to prototypes that haven’t been released yet. This allows them to check out the interface and user experience before committing to a purchase decision.
19. A Single Purpose Means That Every Team Member Focuses On Their Particular Area
It stands to reason that if a project involves various departments, it becomes harder to manage. However, with a POC, the workload is split across all members giving them a sense of accomplishment.
20. All Parties Benefit From Being Open About Progress
Thanks to a POC, everyone involved can share updates regarding the status of the project. This means that everyone stays informed and there is no confusion as to what is taking place.
21. A POC Helps Establish Who Will Be Responsible For Various Parts Of The Project
By dividing responsibilities amongst various groups, a POC allows everyone to feel comfortable knowing what they will be responsible for. This makes everyone accountable for their particular section and encourages collaboration.
22. A POC Allows Different Areas Of Expertise To Coexist
For instance, if a software engineer is assigned to handle front end coding and UI/UX design, he or she can collaborate freely with designers and UX specialists respectively.
23. POCs Eliminate Redundancy
Due to a lack of funding, it is likely that a few roles will overlap. Rather than duplicating efforts, a POC removes redundancy and increases efficiency.
Proof of concepts (Pocs) can be used when developing new ideas or products by creating an early prototype that demonstrates some features or functions of the product/service. A basic definition of a proof of concept is “a preliminary test”, although this term has been adopted more broadly. The best way to define a proof of concept is as "an experiment designed to evaluate whether a project will succeed". A proof of concept can also be defined as a short-term activity which helps determine if a larger project should go ahead. It provides a method to demonstrate the feasibility of a proposed solution before spending money on a full scale implementation.
The purpose of a Proof of Concept (POC) is to provide enough evidence of viability, so that the potential investor feels comfortable with the investment decision. So why not just skip the hassle of writing up a formal document and get straight down to doing something useful. Well, because a lot depends upon the outcome of the POC itself. If the result is positive, then there's no point going through all the rigmarole of getting approval from investors etc., but if the results aren't promising, then the POC could end up costing time, effort and potentially lots of cash!
So how does one go about deciding what type of POC to undertake? There are many factors to consider, such as who might need to see it, where it needs to take place, what resources may be required, how much work can be involved, how long would it take, and what is expected to happen at each stage? These questions alone can seem like an impossible task to answer - but they're really quite simple once you have a clear understanding of what exactly you want to achieve. You'll find that most people start off with a rough outline of their idea, and try to fill in the gaps later. This is usually done using notes taken during brainstorming sessions, emails sent between team members, and other informal conversations.
There are various types of proofs of concept out there, including white papers, prototypes and mockups. Each of these different methods have their own benefits and drawbacks, depending on the nature of the project. For instance, a white paper is great for demonstrating the value proposition behind a service, whereas a prototype allows users to interact with the system in real life scenarios. Mockup designs allow developers to visually showcase how their application works, while still being able to change certain aspects easily. Ultimately though, it comes down to personal preference, or perhaps even convenience - whatever suits you best.
If you'd rather avoid any risk, and make sure everything goes according to plan, then you can always opt for a fully tested POC. In fact, if you've already got funding lined up, then it makes sense to use this option instead of trying to convince someone else to invest - especially since the POC will show them what you intend to deliver. However, you must remember that even the smallest details matter, and sometimes this can mean taking extra care over the documentation process. As well as providing a comprehensive record of the steps taken, it's important to include screenshots and video footage too. Don't forget to keep track of progress throughout the whole thing too, along with details about every meeting held, and every person present. Not only will this help you prove the worthiness of your proposal, it will also give you a good insight into how others perceive your idea.
But what happens after the POC is complete? How do you know if it was successful? And how do you decide whether you should continue working on it further? What we call 'the next phase' often involves refining the original POC, or creating additional ones based on feedback received from those who saw the previous version(s). Sometimes the final product will simply be a polished up reworking of the initial design, whilst at other times it will involve completely redesigning the entire product. Whichever route you choose, it's essential to ensure that you follow proper procedures and protocols. This means making sure everyone knows exactly what tasks need to be carried out, and when. Then, there's the question of what happens afterwards. Will the POC lead directly into production? Or is it meant to serve as a foundation for future developments? Whatever the case, having a solid strategy in place beforehand will save you both time and frustration.
Finally, don't forget to celebrate your success! Whether you had a big budget allocated to your project, or were lucky enough to hit the jackpot with the perfect client, it doesn't necessarily mean that you should stop here. Remember, the goal of a POC isn't to validate the value of your idea. Instead, it aims to demonstrate its worthiness to your peers and superiors, thereby helping you secure funding, gain support, or win over critics. But if you feel that you've achieved what you set out to do, then surely you ought to enjoy yourself? After all, you deserve a little bit of fun now and again...
There are many different types of proofs of concept but most fall into one of two categories – functional prototypes or technical demonstrations.
Functional Prototypes - These are usually created for evaluation purposes. They may not even have any user interface elements at all. Instead they focus purely on functionality with no aim of being production ready. This type of proof of concept aims to show how well a particular feature works.
Technical Demonstrations - These are created with the intention of showing off the capabilities of a piece of technology. For instance, a company might want to create a demonstration video using their latest 3D graphics program instead of actually building it themselves to show customers what it would look like.
In both cases there are benefits and drawbacks from choosing one over another depending on the situation. In general however, it's better to choose something that focuses solely on function rather than design so that later changes to the application won't require rework. If possible, it's often useful to try to keep these proofs of concept separate from your regular code base so that bugs don't become embedded within the main app.
Benefits of Functional Prototypes
Creating a functional prototype gives developers a chance to see exactly how users interact with the system without having to worry about usability issues. By doing so, they'll find out quickly if the core parts work properly and if the overall experience meets expectations.
One benefit of a functional prototype is that it allows you to make very rapid progress with development since you're only working on the core functionality, leaving the design decisions until much further down the line. Another advantage of a functional prototype is that it makes sure that the end result looks good enough to be able to sell the idea to potential investors.
