Answer 5

Soft Systems Methodology (SSM) – Understands complex problems from multiple viewpoints

Usability Engineering Lifecycle – Structured approach to usability from start to end

Star Lifecycle – Emphasizes iteration and constant evaluation

Participatory Design – Direct user involvement at all stages

Question 6
