Product Validation

Product validation is the process of ensuring that a product idea solves a real pain point for a specific group of users
The purpose is to help avoid wasting time, money, and effort of investing heavily in building and launching a product no one needs or is willing to pay for
Product validation includes both validating the problem and the solution
Product validation is most helpful when done before building the product but can also be done afterwards

Customers Research - the most important thing is to validate the problem that was identified during the research and that it’s worth solving (it is an important problem for the target audience) and has a big enough market
Product Discovery - the next most important thing is to validate that the solution (the defined product) indeed solves the problem in an efficient and effective manner (this is especially important in case this is a new solution in the market)
Roadmap planning - it is also important to validate the specific features planned in the upcoming roadmap and validate it is indeed needed and indeed solves a problem within the scope of the product
Build - it is possible to build part of the product (or even part of a feature) and perform validation on that part alone
Go To Market - it is possible to expose the product (or feature) to only a part of the users and perform validation on that group first, or, expose more than one option of the feature in order to validate which version is better
