Purpose of phase is to:

  1. Identify Candidate Technical Solutions
  2. Analyse Candidate Solutions for feasibility
  3. Recommend Candidate System as target solution to be designed


5.1 Identify Candidate Solutions

5.2 Analyse Candidate Solutions

5.3 Compare Candidate Solutions

5.4 Update the Project Plan

5.5 Recommend a system solution


  • Candidate Systems Matrix
  • TELCOS feasibility

Feasibility Checkpoint: GO or NO-GO?


  • System Users
  • System Designers (System Builders)
  • System Analysts
  • System Owners


  • System Proposal (or Request for System Proposal)
