The value of validation: How your capacity plan earns its credibility

Validation is the discipline of testing whether your capacity planning model reflects operational reality. Without it, errors can persist unnoticed, leading to overstaffing or understaffing by 10% or more, costing organisations in unnecessary spend or lost revenue. In a year where many teams are resetting and redefining how they plan, forecast and allocate resources, validation becomes more than a technical check. It is how confidence in decisionmaking is built and sustained. In this article, I explain what validation is, how to perform it effectively and why embedding it into your planning process is essential to keeping capacity plans credible and fit for purpose.
