12 Steps to Useful Software Metrics – Data to Information to Knowledge

In my last blog, Measurement Defined, I talked about Norman Fenton’s definition of measurement as “the process by which numbers or symbols are assigned to attributes of entities in the real world in such a way as to describe them according to clearly defined rules."  Once we perform the measurement process, we have one or more numbers or symbols, these are data items.  Data items are simply “facts” that have been collected in some storable, transferable, or expressible format.

I have been part of the Software Engineering, Software Quality and Software Project Management profession for over thirty-five years now.  I have written many papers and articles, presented at many conferences and even written the book The Certified Software Quality Engineer Handbook.  So I thought it was about time that I stepped into the 21st century and started blogging. 

Software Quality Engineering – Quality Defined

Since this is a blog about software quality engineering, it seems appropriate to start with a definition of quality.  However, the industry has not, and may never, come to a single definition of the term quality.  For example, the ISO/IEC Systems and Software Engineering—Vocabulary has the following set of definitions for quality:

1. The degree to which a system, component, or process meets specified requirements
