TL;DR
Cost management estimates, budgets, and controls project spending to keep work financially viable.
Definition
Cost management includes estimating costs, creating a budget baseline, and tracking actual spend. It also defines reserves and rules for approvals so financial surprises are minimized. Effective cost management aligns spending with scope and schedule, enabling informed decisions when tradeoffs or changes arise.
Decision impact
- It sets the budget baseline and funding approvals for the project.
- It determines when corrective action is needed as spending deviates.
- It influences scope decisions by showing the cost of changes.
Key takeaways
- Estimate costs at the work-package level for accuracy.
- Include contingency reserves for known risks.
- Track actuals against the baseline to spot variance early.
- Use change control to evaluate budget impact before approval.
- Communicate cost status with clear, shared metrics.
Misconceptions
- Cost management is not just recording expenses after the fact.
- Being under budget is not always success if scope or quality suffers.
- Approved budgets still require monitoring and adjustment.
Worked example
An IT upgrade project creates estimates for hardware, labor, and vendor services, then sets a baseline budget with a contingency reserve. Midway, vendor costs rise due to supply delays, so the team uses the reserve and revises the forecast. A change request for new features is evaluated against remaining budget and rejected to protect the delivery commitments.
