In any product, I believe that users play one of the important roles. Who will try and give feedback to the product if there are no end user involve?
In this chapter, it is said that “Treating your users as co-developers is your least-hassle route to rapid code improvement and effective debugging.”
Users are the one who tells you what the problems of your product are. What are the certain features that are needed for you product, etc. Treating the users as your co-developers may save you a lot of time, effort and money. It is said that it is effective. Since users often leave feedbacks and comments to the product, these feedbacks may help you to improve your product.
