Thinker of the Day | James E. Kelley Jr.

Contribution – Co-developed Critical Path Method (CPM) with Morgan R. Walker at DuPont in the late 1950s.

• Kelley and Walker introduced CPM to identify the sequence of activities that determines the minimum completion time of a project.

The central concept
A delay in a critical activity can delay the entire project.

1. Critical Path – Longest-duration sequence of dependent activities determining project completion time.

2. Activity & Dependency – Projects are broken into activities with defined relationships.

3. Float/Slack – Non-critical activities may have some flexibility without affecting the overall project deadline.

4. Time Cost Trade off – CPM allows managers to consider “crashing” activities reducing completion time by allocating additional resources at additional cost.

for e.g. In a highway project land acquisition → tendering → construction → quality inspection → commissioning form interconnected activities. Delay in a critical activity can postpone the entire project.

CPM converts project management from mere scheduling into strategic identification of activities whose delay has system-wide consequences.

Keyword of the Day | Administrative Sclerosis

It refers to the gradual hardening of administrative structures, procedures and routines, making an organisation rigid, resistant to innovation and less responsive to changing circumstances. The administration continues to follow established procedures even when those procedures no longer serve their original purpose.

for e.g. A citizen administrative request may pass through multiple hierarchical levels, repeated noting, signatures and physical verification, even when the information may be already available digitally.
