Response time is an excellent internal measurement, but it won't get you a place at the executive table. Broaden your focus to include how IT can contribute to the bottom line. Measurements focus inward rather than outward. Stop thinking of IT as a technology wunderkind. Making a process 20 percent faster is immaterial if the business users don't think speed is relevant.
Measurements lack the context of business drivers.
Technology is an enabler, not a driver of success. If you don't know what drives a business unit's success, you can't offer a solution to address those processes that make it happen. Measurements are couched in technojargon. Avoid a tower of Babel. Cast your metrics in a language consistent with the one your audience is comfortable with.
