I’d highly recommend PuMP. Most companies jump straight to trying to come up with ways to measure performance without understanding why they are doing it. PuMP takes you through a process that creates the foundations for determining how measurement should be developed and how to get the right buy-in across an organisation. I wonder how many times measurement fails because it has no basis for existing - lots in my experience. PuMP will help you land it first time!
