(4) Right, designing for ease of maintenance is a consideration. Hardware
engineers will be most concerned with the reliability of the system and its
Life-cycle costing will be the primary concern of the
industrial engineers and accounting staff. However, you may be involved in
all these processes as a team member.
In this demonstration and validation phase you need to be especially
concerned with features of the equipment which will result in ease of
maintenance and, most especially, with performance requirements and how they
interact with ease of maintenance.
So what if it can be beautifully
maintained but, because of low human performance reliability, it seldom
works? Can you recall what some of these features are? Think about it for
a few seconds and see if you can name at least three.
accessibility, ease of replacement, work space configuration, packaging, and
These are all aspects of maintenance which need to be
incorporated into the original design plans. Concern for these features at
this early stage may result in fewer problems over the life cycle of the
Okay, before you finish thinking about the acquisition process, let's
recall the final two stages in this process. These stages are:
(1) Task analysis and human engineering requirements. Turn to Page 37.
(2) Full scale development and production and deployment. Turn to Page 4.
(3) Simulation production and evaluation. Turn to Page 82.
