What is Project Time Management?

• Project Time Management
• - focuses on the constrains and overall project
  objectives associated with developing schedule.
• - one of knowledge areas including the processes
  required to ensure timely completion of the
  project.

3
Process Groups Time Mgmt Activities
4
1. Activity Definition
- identifying the specific activities that must
be performed to produce the various project
deliverables.
5
2. Activity Sequencing
- identifying and documenting interactivity
dependencies.
6
3. Activity Duration Estimating
- estimating the number of work periods that will
be needed to complete individual activities.
7
4. Schedule Development
- analyzing activity sequences, activity
durations, and resource requirements to create
the project schedule.
8
5. Schedule Control
- controlling changes to the project schedule.

Task Dependency Types
10
Precedence Diagramming Method (PDM)

• Activities are represented by boxes
• Arrows show relationships between activities
• More popular than ADM method as used by PM
  software
• Better at showing different types of dependencies
• In PDM, finish-to-start is the most common
  relationship

11
Activity Diagramming Method (ADM)

• Uses arrows to represent activities
• Connects activities with nodes
• Uses only finish-to-start dependencies
• May require dummy activities to define
  relationships

12
Schedule Development

• Fast Tracking
• Performing critical path tasks in parallel and
  riskier than crashing
• Eg,.Design is half finished and start coding
• Crashing
• Analyze cost and schedule trade-offs
• Determine most compression for least cost
• Crash the tasks that cost the least first,
  focusing on minimizing project cost

13
Schedule Development

• CPM (Critical Path Method)
• Calculates deterministic early and late start
  and finish date
• Single estimate
• Focus of CPM is on calculating float
• Slack (Float)
• The amount of time a task can be delayed
  without delaying the project
• LF-EF or LS-ES , EFESDuration,
  LSLF-Duration
• Activity A LF 15, EF 5
• LF EF 15 5 10

14
Schedule Development

• PERT (Program Evaluation and Review Technique)
• PERT differs from CPM in that it uses the
  distributions mean instead of the most likely
  estimate used in CPM
• Expected mean value P4(L)O/ 6
• PERT is seldom used today, but very popular for
  cost estimating obtaining MEAN and standard
  deviation
• Critical Path
• Tasks with zero floats, path with longest duration

• Q2. You are the project manager for a new project
  and have figured out the following dependencies
• Task 1 can start immediately and has an estimated
  duration of 3 weeks
• Task 2 can start after Task1 is completed and has
  an estimated duration of 3 weeks
• Task 3 can start after Task 1 is completed and
  has an estimated duration of 6 weeks
• Task 4 can start after Task 2 is completed and
  has an estimated duration of 8 weeks
• Task 5 can start after task 4 is completed and
  after Task 3 is completed . This task takes 4
  weeks.
• What is the duration of the critical path?
• A. 18.5 weeks
• B. 19 weeks
• C. 20 weeks
• D. 18 weeks

Q4. You are taking over a project and determine
the following Task B has an early finish of day
3, a late finish of day 6, and an early start of
day 2. Task L is being done by a hard-to-get
resource. The CPI is 1.1 and the SPI is 0.8.
Based on the information above, what would you be
most concerned about? A. Float B. Resources C.
Cost D. Schedule
