バジェット

A budget is a planned allocation and limit of resources or costs.

Updated: 04/27/2026
What it means

A budget estimates required costs, sets spending limits, and allocates resources to guide cost control.It links objectives, scope, resources, and time, serving as a baseline for alignment and change control.It supports decisions to protect quality and schedule.

When it helps

Clear scope and objectives align priorities and reduce rework in decisions. Visible dependencies make schedule adjustments and resource trade-offs faster. Change and risk impacts can be assessed early, improving alignment.

  • Clear scope and objectives align priorities and reduce rework in decisions.
  • Visible dependencies make schedule adjustments and resource trade-offs faster.
  • Change and risk impacts can be assessed early, improving alignment.
How to use it
  • Define deliverables and acceptance criteria to prevent scope drift.
  • Record assumptions, constraints, and exclusions for shared expectations.
  • Link dependencies to owners and dates to ease coordination.
  • Review progress against the baseline, not just activity.
  • Log changes with reasons and impacts to maintain transparency.
Example

Example: Separate labor, vendor, and contingency costs, then review variances each month.When change requests arise, assess impact and renegotiate priorities with stakeholders.Review progress weekly and agree on mitigation if delays appear.Document major changes and approvals for traceability.

Common mistakes
  • Plans are not immutable; controlled changes are expected.
  • More detail is not always better if it raises maintenance cost.
  • Documentation alone does not deliver results without execution.
