Development Process
Methodology
After the initial requirements analysis but before software design The first architecture is also a communication basis with the customer Inputs for the development of the architecture:
1 2
Requirements Context (technical, organizational, business, ...)

Requirements
Analysis
At the beginning there is always a customer who wants a specific software system Customer “wishes” are always informal Interviews, some documents, some Excel tables, ... We need to analyze such informal records and structure it Requirements engineering is a huge field but we just illustrate here one possibility

Analysis
The results of the requirements analysis:
1 2
Functional requirements Non-functional requirements
(a) Runtime qualities (b) Non-runtime qualities
3
Contextual requirements
