Performance Capacity Planning

Performance Capacity Planning

Overview

Use this skill to build capacity plans that keep services reliable under growth and peak demand.

Scope Boundaries

• Use this skill when the task matches the trigger condition described in description.
• Do not use this skill when the primary task falls outside this skill's domain.

Shared References

• Capacity forecast rules:
  • references/capacity-forecast-rules.md

Templates And Assets

• Capacity model template:
  • assets/capacity-model-template.md
• Headroom policy template:
  • assets/headroom-policy-template.md

Inputs To Gather

• Current workload profile and growth assumptions.
• SLO/error-budget and availability constraints.
• Scaling mechanics and provisioning lead times.
• Peak-event and failure-mode scenarios.

Deliverables

• Capacity model with risk-based thresholds.
• Headroom policy by service tier.
• Forecast-driven scaling and escalation plan.

Workflow

1. Build model in assets/capacity-model-template.md.
2. Apply growth/headroom policy via references/capacity-forecast-rules.md.
3. Define thresholds and escalation points.
4. Validate against plausible growth and burst scenarios.
5. Publish ownership and review cadence.

Quality Standard

• Forecast assumptions are explicit and testable.
• Headroom policy aligns with reliability objectives.
• Saturation thresholds trigger actionable responses.

Failure Conditions

• Stop when plan cannot support forecasted demand.
• Stop when thresholds are non-actionable.
• Escalate when capacity risk exceeds policy tolerance.
