Allowing to analyze very early in a project the pros and cons and to realize its feasibility, the Proof of Concept is increasingly used. Find out what it is, how it differs from other tools and methods, and how to successfully complete your Proof of Concept.
The definition of Proof of Concept
The PoC, Proof of Concept, is a method that makes it possible to evaluate the feasibility of a project.
It is part of the project framework and is particularly widely used in Agile methods.
It can be used for the creation of a new product or software, or on the occasion of a reorganization or the launch of a service.
The goal is to answer two big questions: is there a need for this product or service, and is it feasible? The feasibility and performance of the concept concerned are studied from several points of view: marketing, technical and economic.
For example, it may involve launching a study, analyzing data, or launching a minimal prototype that will allow you to see what the concept should look like, its main functionalities, etc.
What is the difference between PoC and MVP?
Do not confuse Proof of Concept and Minimum Viable Product (MVP).
Indeed, the Minimum Viable Product is a version of the product intended to be marketed to be tested by the end customer. It is in working order, even if it is not yet the final version: it may for example be missing features that are not yet ready.
The MVP comes later in the project, it is one of the last steps before the final launch of the product or service.
What is the difference between a Proof of Concept and a prototype?
For its part, the prototype arrives after the Proof of Concept but before the MVP. This is a version that allows you to get an idea of the product, but it is not intended to be marketed.
Proof of Concept is essential if you are launching a new service or product that does not yet exist on the market. You will need to go through this step in order to verify that the project is feasible, especially from an economic point of view.
If, on the other hand, you launch something that already exists, for example, your own version of the software or a product already marketed by one of your competitors or a new version of one of your own products, you can go straight to the prototype, since the concept has already been proven to work.
What are the benefits of Proof of Concept?
Checking the feasibility of a project through a Proof of Concept has several advantages:
- Make a decision from the start of the project, on its launch or not.
- Identify potential problems early on and start discussing solutions.
- Evaluate and anticipate customer reactions long before the product or service hits the market.
- It’s a time saver: no need to embark on a multi-year project if it is proven that it is destined to fail.
- This avoids financial losses: a project launched without certainty of success is expensive, and the PoC makes it possible to reduce this risk.
What are the disadvantages of Proof of Concept?
The Proof of Concept also has some drawbacks, which are generally more related to the way to go about it than to the process itself. Indeed, many companies neglect this phase by devoting neither the time nor the necessary budget to it.
The disadvantages of Proof of Concept can lead to unfortunate consequences:
- Lack of relevant data that could help reach a decision and therefore a waste of time.
- Risk of abandoning a project that could have proved viable by looking into the question in more detail.
- Bad evaluation of scalability: it is not because the project works in theory on a small scale that its deployment for commercialization will necessarily be a success.
What methodology should be followed to launch a PoC?
To succeed in your PoC, five main phases must be respected:
- Initiation: This phase makes it possible to analyze the objectives of the PoC: what is its purpose, what are the expected results, who must be convinced?
- Definition of the scope: Who are the targets of the PoC, which tools to adopt (prototype, study, questionnaire, etc.), which data to collect, how long will it take?
- Realization: It’s time to take action and launch the PoC!
- Analysis of results: The information collected must be analyzed to answer the main question of the PoC: is the project feasible?
- Conclusion: This last phase is the time to make a decision: will the product or service be launched, and if so, what are the next steps?
