In theory, the WBS tasks should have technical objectives. In practice, this is not often well
defined. In some cases, the specification requirements are referenced, but may not actually be
what is expected at the point in the program where an early design is analyzed or prototype tested.
The use of TPMs can provide a better linkage as will be described in the following paragraphs.
Critical Path
Basic. The path in a network schedule with the least (or most negative) schedule slack is the
critical path. This concept has long been used for managing the highest risk schedule events on a
project. A project may have more than one equally critical path or management may decide to
track more than just the most critical path. Tracking the three most critical paths addresses the risk
that a problem may appear on a path that is close to critical and overtake the original path without
warning. Figure 2 is from a project where the critical path analysis identified multiple parallel
critical paths leading to fixed events. After identification of this situation, action was taken to
address this significant project risk. In this instance, multiple paths had to be monitored
throughout the program.
Figure 2. Critical Path Analysis Example
Technical Critical Path
Limited References. The term was introduced to this paper by Dr. Yeo of the Nanyang
Technological University during discussions about TPMs, February 19, 2009. It can be found in
various references where it addresses the series of technology developments that are necessary for
a development to be successful. One example is a briefing on planning for advancement in solar
energy by the U.S. Department of Energy (2006), Figure 3.
