• This is a great method to get started, but make sure you are answering a relevant question. It may not always be "What do you use to measure how your business is doing?". If you're working with a CIO and the CIO wants to improve change management processes, the question might be something like "What runs where?". In that case, you would dig through the spreadsheets to find which applications run on which servers and so on. Being able to easily answer a relevant question is what makes the DW valuable to management.
