Critical Path Analysis
(complete and submit individually)
Critical path analysis, or “CPA” is a project management tool widely used by project managers to handle
complex and time-sensitive operations. CPA aids managers in identifying the relationships/dependencies
between project activities, the duration of each activity, and the earliest and latest start/finish times for
each activity (in order to stay on-track for completion). Through this analysis, project managers can
determine the most efficient way of completing projects.
Consider the following series of activities in a business planning to launch a new product:
Activity
A – Conduct consumer research
B – Design consumer research presentation
C – Design product concept
D – Design and test product prototype
E – Develop and test production tooling
F – Notify suppliers of requirements
G – Commence production
H – Conduct launch promotion

Step 1: write in each activity letter (A, B, etc.) and the duration underneath it
Step 2: calculate the early start and early finish for each (early start + duration = early finish) = if
two activities feed into another one (precede it) go with the larger number, because the activity
can’t begin until both are complete
Step 3: use the backward pass to find the late start and late finish for each activity (late finish –
duration = late start). Bring your final activity’s late start number into the late finish box for the
activity that precedes it and continue on all the way backwards to the first activity. *If two
activities feed from another one, the smaller number wins
Step 4: to identify the Critical Path, identify which activities have the same numbers for their
early finish and late finish
Step 5: to identify float/slack time for an activity, calculate the difference between the early
start and late start for that activity
What is the planned duration of the project?
What is the critical path for this project? Remember, the critical path is the sequence of
project activities which add up to the longest overall duration. It determines the shortest
time possible to complete the project.
What would happen if you delayed any one of the activities on the critical path?
How many months could activity E be delayed (i.e., “floated” or “slacked”) before it began to
affect the end date on the project?
