Clients may succeed in communicating with business clients and partners, but when it comes to developing websites or software, they lack the background to explain the details of what they want. If a client allows the developers to take the reins, in most cases the final result may disappoint and not be exactly what the client wants. This way, each interaction is reviewed by the team of developers and the client. The aim is to keep the client     

Nowadays the most modern designers work with Sketch. Because of its ability to draw in the interface interaction and its tiny weight.

• “what features were delivered to week/month ago”,
• “what features are planned to be released this/next week”,
• “what was the last release structure (how many new features, bug fixing, UI or UX improvements, etc)”.
