Analysis

Intro

• Requirements Analysis is building models of requirements that can be evaluated.
• It is also about identifying conflicts between requirements.
• Formally modeling natural language requirements is hard ! also, requirements also conflict with multiple stakeholders.
• Techniques used are: UML and SCR tables.

Analysis using UML

• UML modeling can be used to analyse requirements.
• Use cases (Are these part of UML ?) - to define functional requirements.
• Static Structure Diagrams - To model object and relationships. [TODO : Isnt this stepping into design ?]
• Dynamic behavior diagrams - to model interaction and sequencing.
• There are also UML analysis patterns which help reuse existing models. These are usually domain specific.
  • Note: this is different from a design pattern.
