time can be reduced to as little as four hours by improving the process. The
process improvement objective can be stated this way: “High-pressure air
compressor fourth stage seals are repaired in four hours or less, with no increase in
the mean time between failures for the repaired parts.”
If the way firefighters check for explosive gases in a compartment during a fire drill
is described simply as “unsatisfactory,” few people will know how to state the
process improvement objective. But, if the nature of the problem is clearly stated as
“50 percent of the firefighters do not know how to operate the Explosivemeter,” the
objective can be stated this way: “At least 95 percent of our firefighters can operate
the Explosivemeter in a satisfactory manner.”
A team formulating a process improvement objective may find it helpful to proceed in this
way:
Write a description of the process, starting, “The process by which we...”
Specify the objective of the process improvement effort.
Operationally define the objective in writing. (See Module 1 of the Basic Tools for
Process Improvement.)
Use numerical specification limits for process improvement objectives whenever
possible. (See the discussion of process capability in Step 7.)
A final note: Without a stated improvement objective, the team may conduct meetings but
achieve little improvement in the effectiveness, efficiency, or safety of their process. A
clearly stated process improvement objective keeps the team’s efforts focused on results.
The tools the team needs to select the process to work on and establish the process
improvement objective are described in the following modules of the Basic Tools for
Process Improvement:
Module 1:
Operational Definitions
Module 2:
Brainstorming
Module 3:
Decision-Making Tools
Module 8:
