Stage 2: Analysis

20 Feb

The second phase of SDLC is Analysis.

There are three steps in the Analysis stage:

  1. Understanding the old/current system(collect facts from existing users)
  2. Identifying how the old/current system can be improved (approach users and use different data gathering techniques)
  3. Developing specifications for the new system (what are possible solutions)


Data Gathering Techniques include:

  1. Traditional Methods [Interviews, Surveys, Observation and Studying Business Documents]
  2. Modern Methods [Joint Application Design, Prototyping and Group Decision Support Systems]
  3. Radical Methods [Business Process Re-engineering]


Key Deliverables:

  1. Business Requirements Document
  2. Data Flow Diagram of Current System
  3. Entity Relationship Diagram of Current System


  • The analysis phase addresses what can be done for the new system.
  • The design phase will set out how it can be done in my next post.
