I'm an organizational psychologist who has also been the executive making the decisions I wished we had data to inform. Every company has systems for how people get hired, developed, promoted, and paid. Often they were never designed. They just accumulated. For 20 years I've built them on purpose, with evidence instead of habit. I've done it as consultant cross every sector, inside the federal government, inside a company that scaled from under $4M to over $260M, and inside my own firm. The through-line: most things we call "people problems" are design problems with a human face. Design them better and behavior change becomes the more likely outcome.
