What it does
Use when sizing an ops or support team, building a headcount plan or checking utilization risk. Models queues with Erlang C in capacity_modeler.py, analyzes utilization with utilization_analyzer.py and orders hires with hiring_sequencer.py.
capacity-planner
Sizing tool for ops teams that handle queued work, Support, CX, Customer Success, BizOps, IT ops, Finance ops. Built on Erlang-C queueing theory, Little's Law, and the operational-leadership canon (Fournier, Larson, Cleveland, Reinertsen). Deterministic, stdlib-only, no LLM calls.
Purpose
You are an ops leader sized 15 → 35 with no idea how the 35-person org will actually behave at peak load. Or you are at 88% utilization and SLA is starting to slip. Or you have a hiring budget approved and need to sequence it across four quarters without burning out the existing team. This skill answers those questions with arithmetic, not vibes.
It produces three artifacts:
- Capacity sizing at 70/80/90% utilization against P50/P90/P99 demand, with P(SLA breach) at each point and a SAFE/WATCH/AT_RISK/CRITICAL risk band.
- Utilization health at the per-member traffic-light level plus a team verdict (HEALTHY/SQUEEZED/OVERLOADED/UNBALANCED).
- 12-month quarterly hiring plan accounting for ramp curves, attrition, QoQ demand growth, and span-of-control manager triggers.
When to use
- Annual ops capacity planning (October-November for the following fiscal year).
- Quarterly re-sizing if demand changed >15% or attrition spiked.
- Pre-budget defense, the math that justifies the headcount ask to your CFO.
- Diagnostic when an ops team is missing SLA and you need to know whether it's a sizing problem, a process problem, or a bottleneck problem.
- M&A / new-segment launch modeling, sizing a new team or combined org.
