We have an idea to build up a messenger like WhatsApp. We have to list down all the product requirements as detailed as possible. There are different types of product requirements: business, functional and non-functional. Business requirements typically answer how the product will address the needs of your company and its users. They also reveal the business model of the app and what problems it can solve. Functional requirements are about the functionalities that will be implemented in the app. Non-functional requirements describe how these functionalities will be implemented. So a good product requires not only to describe the core features but also to have properly written requirements. Collecting and analyzing product requirements is very important before developing an app.
Functional requirements provide the information needed by designers, developers, quality assurance specialists, and project managers. We use WhatsApp as a product example. Key features and their definition will be shown in mindmaps.
