HKSM

A structured reference that, for each WBS element, records its deliverables, the work to be performed, and related schedule details.

Key Points

• Expands the WBS by adding descriptive details for each component or work package.
• Typically includes scope description, deliverables, activities, acceptance criteria, owner, milestones, estimates, and schedule info.
• Reduces ambiguity and supports planning, estimating, risk analysis, and control.
• Each entry maps to a unique WBS code and can be tailored to the needed level of detail.

Example

On a CRM implementation project, WBS element 3.2 "Data Migration" has a dictionary entry listing the deliverable (customer data migrated to the new system), key activities (extract, transform, load; data validation), acceptance criteria (99.5% accuracy; no critical data loss), responsible owner (Data Lead), dependencies (environment ready, source data freeze), and a schedule window (weeks 8-10).
