What this is

Performix is a protected-feedback diagnostic that finds the single condition blocking a team's performance — grounded in CAMS: capable people don't produce performance unless Alignment, Motivation, and Support are also present. It is psychometric-first: the diagnostic engine is measurement (IRT, MaxDiff, Monte Carlo / EVPI–EVSI, Wilson intervals), precomputed from real psychometrics — not generated on demand by a language model. AI is a first-class consumer of the substrate (schema mapping, evidence extraction, item-candidate generation, ETL), never the engine.

The diagnostic mindset: refuse the laundry list of "best practices." Identify which of {Capability, Alignment, Motivation, Support} is the binding constraint right now for this team — and apply resource only there.

Who it's for

Leaders and people-analytics teams diagnosing why a specific team isn't performing; executives wanting a measured readout, not a dashboard of generic metrics.

How it relates to the portfolio

Performix is a reference implementation of the seven-capability doctrine and a consumer of services owned by other repos — it composes, it does not re-implement. The CAMS diagnostic runs real psychometrics against the toolbox reincarnation spoke; the Executive Readout consumes Principia measurement methods. Algorithms never live here — vendor contracts only.
