Functional analysisNeeds for a technical system (why is it developed?)
To whom is the system useful?
On what is the system acting?
Team/ University Fake Fruits and vegetables
What is the goal of the product or service?To harvest as much as possible of fruits and vegetables in 90s
System: Autonomous robot

Functional analysisIn the functional/logical viewpoint:
A requirement can be functional or non-functional?
A function can be seen as an INTERFACE between two elements of the environment. In the representation popularized by Pahl and Beitz, a function is an interface between two types of flows.
