Project Time Management

Includes the processes required to

accomplish timely completion of the project;

involved 7 processes used to in developing

time schedule

The schedule can have any format.

4

6.1 Plan Schedule Management

Establishing the policies, procedures, and

documentation for planning, developing,

managing, executing, and controlling the project

schedule.

The key benefit is to provide guidance and

direction on how the project schedule will be

managed.

and connected with

arrows (Activity on

Node). 18

5. Reserve Analysis

34

Estimate Activity Duration: T & T (2)

6. Three-point Estimate

35

Program Evaluation & Review Technique (PERT)

Uses a weighted average duration estimate to calculate

activity durations.

36

Gantt Chart

Bar charts are relatively easy to read, and are

frequently used in management presentations.

37

38

estimates of the likely duration of each

activity as well as the range of possible

results ( 10 ± 2 day )

sequence, durations, resource

requirements, & schedule constraints to

Resource Leveling & Smoothing

Duration Compression

Duration compression is a special case of

mathematical analysis to shorten the project schedule

without changing the project scope

Crashing : cost & schedule tradeoffs are analyzed

to determine how to obtain the greatest amount of

compression for the least incremental cost.

Fast-tracking: doing activities in parallel that would

normally be done in sequence. Fast tracking often

results in rework and usually increases risk.

Float

• Total float (Slack): the amount of time an activity

can be delayed without delaying the project end

date or/and intermediary milestone.

• Free Float (Slack): the amount of time an activity

can be delayed without delaying the start of its

successor.

• Project Float: the amount of time a project can be

delayed without delaying the externally imposed

project completion date.
