Responsibility Assignment Matrix (RAM)

A tabular chart that links each work package to the specific people or teams assigned to carry out the work.

Key Points

  • Cross-references the WBS with roles or organizational units to show who does what.
  • Clarifies responsibility and ownership; can be expanded using RACI (Responsible, Accountable, Consulted, Informed).
  • Prevents gaps, overlaps, and confusion about task assignments and handoffs.
  • Created during resource planning and updated as staffing or scope changes.

Example

A project manager builds a RAM that lists WBS work packages down the left and project roles across the top (e.g., Business Analyst, Developer, Tester). For the work package "WP-3: Build Login Module," the RAM shows the Developer as responsible, the Tech Lead as accountable, the Security Analyst as consulted, and the QA Tester as informed. This makes it clear who will do the work and who must be engaged.
