I have been doing this work for (gasp) over 25 years. I know you know. And I know you know I keep saying the number out loud (and gasping, each time) because I need help believing it's real as, truth be told, it feels like both longer and a lot shorter than that. Because so much has changed and yet so much has stayed doggedly the same. And if I had to identify the greatest (and most frustrating) consistency of the last quarter century, it would be how decisions are made inside big organisations.
