This case study examines how user-developer interaction evolved with a new three-level User Requirements Specification. The focus was on the impact of coarse granularity in operational requirements.

Area of Science:

  • Software Engineering
  • Human-Computer Interaction

Background:

  • Effective user-developer interaction is crucial for software development success.
  • Traditional requirements specifications can lead to communication gaps.
  • A structured approach to requirements can improve collaboration.

Purpose of the Study:

  • To investigate the impact of a three-level User Requirements Specification (URS) on user-developer interaction.
  • To analyze how varying granularity in operational requirements affects communication and collaboration.

Main Methods:

  • A case study methodology was employed.
  • Introduction of a novel three-level URS with coarse granularity at the operational level.
  • Observation and analysis of user-developer interactions during the requirements phase.

Main Results:

  • The three-level URS influenced the nature of user-developer interactions.
  • Coarse granularity in operational requirements led to specific changes in communication patterns.
  • Observed shifts in understanding and negotiation between users and developers.

Conclusions:

  • The proposed URS structure impacts user-developer dynamics.
  • Granularity of requirements specification is a key factor in effective collaboration.
  • Further research is needed to optimize URS for diverse development contexts.
