You can't manage what you can't measure. This often cited quote by Peter Drucker lies at the heart of many things: change management, quality management, staff diversity, environmental footprint, CO2 output … you know it. This is why many millions of dollars, and countless hours, have been invested in creating suitable measurement tools. It's just that: Measurement ≠ Data ≠ Information ≠ Knowledge ≠ Action.
Knowledge and data are two interesting entities: essential for decisions at any one time. And yet evolving with time. And with that, decisions taken some time ago, possibly decades earlier, may prove flawed – in hindsight.
But what if years down the road these insights are resurfaced and either proven to be partially or fully inaccurate? What if the nuggets are suddenly being used in a context that has shifted significantly since? What if our best intended and best-possible informed statements of the past are called out years, decades later?
A few thoughts on this dilemma.
