UML Diagrams - In Various Development Phases

Hi,

Here we’ll see what diagrams are required to sketch in the various phases of s/w development.

• Not all diagrams are compulsory.
• The minimum diagrams according to software life cycle phases are :-

• Requirement phase: - Use Case Diagrams
• Design Phase: - Component diagrams, Class diagrams
• Implementation phase: - All diagrams derived from pervious phases specially class diagram for reverse engineering.
• Testing phase: - All diagrams derived from requirement and design phases for verification and preparing test plans.
• Roll out and close over phase: - All document derived from Design phase and requirement phases.

Below is a sample figure which shows all the documents in relevant phases.

Thanks & Regards,
