Cost contingency (MS Excel, @Risk & Predict!)
Schedule contingency (MS Project, Primavera, Predict!)
PPP rollup of contingency & Management Reserve
The Contract Budget Baseline (Deltek Cobra)

Baseline budget
Generally calculated during bidding process
Only re-calculated if project is re-baselined
Contract established
Responsibility lies with budget holder (Control Account
Manager)
Managed via variance analysis (Earned Value process)

Known risk budget
Project MR is residual risk
Mitigation actions are included in baseline budget
MR held at project level
Authority to drawdown against known risks only
Used for (additional) mitigation and recovery actions
Re-assessed at regular intervals throughout project
Tools manage permissions at PPP levels

Schedule reserve (sMR)
Review individual milestones as well as whole project
Baseline (working) milestones should not include sMR
Contractual milestones should include sMR buffer
Schedule buffers should be managed by project
Drawdown (schedule and budget) against known risks only
Used for (additional) mitigation and recovery actions
Managed via Risk Management process
