Although there are many textbooks available on quality improvement, it is still surprising to see the gap between theory and practice. Most literature on software quality is quite comprehensive, however, it often lacks the goal-driven nature of business. Business is not just looking for ultimate quality, but for the best quality to be given to other goals, such as timeliness, product features, complexity, or cost.
The Goal/Question/Metric method (GQM) supports such a business driven quality improvement approach very well, however, this method is merely published in scientific journals. This motivated us to write a practical GQM guide. We hope this book will inspire you during your quality improvement work in practice or coursework, and sincerely hope the practical material in this book prevents you making some of the mistakes we did.
