How to measure

Starting with measurement is not as easy as it first seems. So you should involve someone with experience. We are very proud that Kobi Vider, one of the world’s most respected professionals regarding advanced statistical approaches and quantitative management, will be acting as our partner. The following article is much inspired from his experience.
Business Goals
Do you know what’s funny about how to measure? Don’t start with the measurements! Start with your business goals. What are the market requirements? What do your customers expect? What does your management require? Uttermost quality? Optimal cost efficiency? Short time to market? Look at your company’s vision statements. Look at the business scorecard. There you will find what your executive management considers to be important for your business. And this in turn will enable to to get senior management attention and involvement.
Information Needs
Break the business goals into information needs. Which kinds of information do you need to find out if you follow your business goals or not. What are the real quality indicators that you need to follow? Defect rates? Or customer satisfaction? Is it neccessary to strictly meet the deadlines? Then focus on milestone trends. Or is it more important to deliver ultimate quality? Then focus on defect rates.
Measure
When you made your information needs clear, then think about measurements. Do not measure what’s easy to measure. Measure what you need to know. Measure output products and measure process performance. Process management tools will help you there. Our Stages process management system contains these kind of measurement features.
Act upon your Measures
Your measurements should be followed by actions. Improve the processes that are out of control or perform out of bounds. If the product quality is not sufficient, analyze why. Missing requirements? Bad design? Poor implementation? And, oh yes, you should have processes before measuring them. Otherwise, you would try to measure chaos.
Added Business Value
Finally, always make clear what’s the added business value of your measurements and the following actions. Let’s say, you measured too many defects and added peer reviews to your requirement analysis and early design stages. Did the defect rate really drop? How much? What does that mean for your business? In Dollars, Yen or Euro. How much did the customer satisfaction increase? Prove the ROI of your efforts. Your management will ask you about it.
