Software and Systems Measurement
It is inherently difficult to manage
what cannot be measured
objectively.
- Walker Royce1
Over the past twenty years, measurement
has evolved from something that was a
"check-in-the-box" process into a
management best practice. Numerous
case studies of essful projects and
organizations have shown the value of
measurement. It is now a key
management discipline, as evidenced by
its inclusion in various process standards,
models, and guidelines such as the
ISO/IEC 15939 standard, Software
Measurement Process, and the Software
Engineering Institute's Capability Maturity
Model® IntegrationSM (CMMISM).
Although it is now widely accepted that measurement is a key best practice in
software development, implementing a essful measurement program is still a
challenge. Many projects anizations still try either to build their
measurement programs around the "ten best measures" or to measure so much
that the program es a maintenance burden and fails.
There is much more to implementing a essful measurement program than just
the measures themselves. The Practical Software and Systems Measurement (PSM)
Initiative and the Rational Unified Process,® or RUP,® are two existing process
frameworks that explain the measurement process. The PSM initiative team
included government, industry, and academic representatives to bring together and
promote the best practices of software and system measurement. RUP contains a
process framework of best practices for iterative, incremental, software and
systems development. This article will show how PSM and RUP can work together
to provide a coherent measurement process. We will in
