PERT Chart and CPM: Table 2.1 Activity List and Duration Table

The document discusses PERT charts and the critical path method for project scheduling. A PERT chart uses nodes and vectors to provide a graphical representation of a project's timeline, tasks, dependencies and critical path. It allows managers to estimate project duration and assess risks. The example shows a PERT chart and activity list for a construction project, with a network diagram mapping the dependencies between tasks. Calculating the critical path reveals the minimum time of 32 days to complete the project.

PERT Chart and CPM

A PERT (Program Evaluation Review Technique) chart, sometimes called a PERT diagram, is
a project management tool used to schedule, organize and coordinate tasks within a project. It
provides a graphical representation of a project's timeline that allows project managers to break
down each individual task in the project for analysis. The PERT chart template uses nodes -- drawn
as rectangles or circles -- to represent events and milestones throughout the project. The nodes are
connected by vectors -- drawn as lines -- which represent the various tasks that need to be
completed.
PERT charts provide project managers with an estimation of the minimum amount of time
needed to complete a project. Managers can also analyse the work breakdown and task connections
as well as assess the risk associated with the project. The breakdown structure makes it easy to
organize a complex project with a variety of moving parts by visualizing the dependencies between
each step of the process.

Critical Path Method

Path 1 = A-B-D-F-H-J-L-N
= 8+1+3+2+4+6+2+1
= 27 days

Path 2 = A-B-E-G-I-K-M-N
=8+1+5+4+4+6+2+1
= 31 days

Path 3 =A-C-E-G-I-K-M-N
=8+2+5+4+4+6+2+1
= 32 days

Path 4 =A-C-D-F-H-J-L-N
=8+2+3+2+4+6+2+1
= 28 days

Project Duration for completion = 32 Days
