Define the system and unit of analysis
Specify process, population, product, time window, boundaries and aggregation level. Without a defined unit of analysis, measures and comparisons may represent different phenomena.
Positions people by performance and potential, making criteria explicit for development, succession, mobility and talent decisions.
Before opening a form, define the question that must be answered. A management tool is useful when it reduces ambiguity, exposes assumptions and makes clear which decision will be made from the evidence produced.
PES-01How can performance and potential be discussed with explicit criteria and longitudinal evidence without turning a simple matrix into a definitive talent diagnosis?
People tools should make criteria explicit without turning managerial judgment into false precision. Observable evidence, context and dialogue remain essential to interpret any score or matrix.
Use them for development, alignment, culture, communication and talent decisions, always with transparent criteria and human review.
A matrix turns criteria into a comparable structure. Before scoring, define scales and the meaning of each axis; otherwise different numbers may represent different interpretations across evaluators.
Specify process, population, product, time window, boundaries and aggregation level. Without a defined unit of analysis, measures and comparisons may represent different phenomena.
Translate abstract concepts into operational definitions, scales, classification rules and data sources. Criteria should exist before the result to reduce retrospective interpretation.
Link each conclusion to data, observations, assumptions and owners. When a score is used, retain its components; when a hypothesis is used, record how it will be tested.
Calibrate when there are multiple evaluators, retain the evidence behind each score and treat the result as decision support — not an automatic replacement for judgment.
An employee has performance 4/5 supported by delivered objectives and potential 3/5 based on learning, complexity and mobility. Placement is calibrated with concrete evidence and is not treated as a permanent label or psychological test.
The example is intentionally specific. Numbers illustrate the reasoning and are not universal benchmarks: limits, scales and targets must be defined for the process being analyzed.Measures should serve reasoning. Whenever possible combine outcome, process and contextual evidence. For time series, look for patterns and variation rather than only point-in-time before/after comparisons.
Ask whether another person, using the same definitions and evidence, would reach a similar interpretation. If the answer depends heavily on individual judgment, refine the operational definition, scale or data source.
Widely used management heuristic. Useful for structuring decisions, but not by itself a causal model or scientifically validated scale.
9 Box is a talent-portfolio tool, not a validated psychometric instrument. Vague criteria amplify halo, similarity and recency bias.
Define an owner, review frequency, official data source and condition for reopening the decision. Link actions to deadlines and indicators, hypotheses to tests, and risks to treatment and follow-up.
