Encyclopedia — Letter R
12 entries in Project Management & Project Controls beginning with R.
RACI Matrix
A responsibility assignment chart that clarifies, for each task or decision, who is Responsible, Accountable, Consulted and Informed — eliminating the diffuse-ownership ambiguity that kills projects.
Rebar Bending Schedule
The dimensioned list that tells the steel-fixing crew — and the fabricator — every diameter, length, shape code and quantity of reinforcement needed for a concrete element.
Refactoring
The disciplined practice of changing the internal structure of code without changing its external behaviour — improving design, reducing complexity, and paying down technical debt without altering functionality.
Release Notes Discipline
The habit of writing honest, useful, timely release notes for every change that reaches users — the smallest engineering practice with the largest and most under-appreciated effect on trust, support cost and adoption.
Release Train
A cadence-based delivery pattern — most closely associated with SAFe's Agile Release Train — that coordinates multiple agile teams to plan, build, and release on a shared, predictable rhythm.
Resource Leveling
A scheduling technique that adjusts activity timing to resolve resource over-allocations, smoothing demand against available capacity.
Retainage
A percentage of progress payments withheld from contractors until defined performance milestones — usually substantial completion and final acceptance — are met.
RFI Management
The disciplined tracking of Requests for Information — the formal channel through which contractors ask designers to clarify, correct, or resolve ambiguities in the construction documents.
Risk Management
The structured identification, analysis, response planning, and ongoing monitoring of uncertain events that could affect project objectives.
Rollback Plan
The pre-agreed, tested sequence for reverting a change if it fails in production — the difference between a five-minute recovery and a five-hour outage.
Rolling Wave Planning
A planning technique that details near-term work to a fine grain while keeping later work at a higher level, then progressively refines as the project proceeds.
Runbook
A written, step-by-step operational procedure that tells an on-call engineer exactly how to detect, diagnose and remediate a specific class of incident on a specific system.
