Requirements collection

All projects starts with a high level scope definition and before starting the real work we need to know the detailed requirements. You may start your housing project with a one line requirement like ‘We need a three bed room, living room, dining and kitchen house’. That is perfectly fine during the very early stages of the project, but before getting into definitive estimates and planning one need to understand the exact requirements in the form of detailed drawings for each room. Before doing that one need to collect the detailed requirements from the key stakeholders of the project.

The key tools and techniques used for requirements collection are;

  • Expert judgment
  • Brainstorming
  • Interviews
  • Focus groups
  • Questionnaires and surveys
  • Bench-marking
  • Document analysis
  • Voting
  • Multi-criteria decision analysis
  • Affinity diagrams
  • Mind mapping
  • Nominal group techniques
  • Observation/Conversation
  • Facilitation
  • Context diagrams
  • Prototypes
