2 ■ Optimize Quality for Business Outcomes
 Any person on the manufacturing floor can stop the
entire manufacturing process if they notice something is
not right.
 Everybody on the assembly line is a quality checker.
 When a problem is spotted early, it’s a lot cheaper to fix
at that point, instead of cranking out a bunch of flawed
cars and later having to rework the design, or possibly
even do a recall.
The HP Quality Model was born out of the question, “How can
we save IT costs for testing and quality management?”
To find the answer, we followed the approach made popular
by Taiichi Ohno, inventor of the Toyota Quality System, and
others. The 5-Why method asks five questions that help lead us
down the right path.
First, we asked: Why is IT so expensive, when hardware costs
are dropping and development technologies have improved
developer productivity?
We found that despite the advancements in IT process and
technology, IT projects are becoming more complex and they
almost always run out of time. When time is short, people tend
to sacrifice the quality of the product.
The Standish Report over the past 15 years shows the rate of
successful projects (that is, under budget and on time) is below
30 percent (Figure 1). The advancements haven’t lowered the
cost. On the contrary, with more complexity, the need for
proper planning and project management is greater.
When budget and time constraints dictate the project parame-
ters, functionality and quality get the short end of the stick.
