AI-generated summary
Different methods for software development include structured method, object-oriented method, service-oriented method, and prototype method. Each method has its own strengths and weaknesses in terms of planning, adaptability, and clarity of requirements. Additionally, formal methods involve mathematical modeling for verification and proof rather than testing.

Main Methods#

Structured Method - Top-down planning, poor adaptability

Object-oriented Method - Bottom-up unclear stage boundaries, strong adaptability

Service-oriented Method - Upgrade of object-oriented coarse-grained, loosely coupled, standardized, componentized

Prototype Method - For unclear requirements
