To track KPIs, most companies use a Balanced Scorecard. This is a tool that has long been used in strategic business management and is designed to provide a framework to manage resources to achieve strategic objectives
most managers only measure outputs, not inputs, which is like telling a Little League team to score more runs, rather than actually explaining how to swing a bat and make contact with the ball. Similarly, most companies measure traffic, revenue or earnings, without considering how to improve the company at an atomic level: how to make a meeting better, or an engineer more productive.
Everyone is held accountable to the chain of command, starting with those at the top. If you own the company, you need to define your role in the chain of command and follow the protocols that you set.
