Questions and Correct Answers |
New Update
Schedule Development - 🧠 ANSWER ✔✔Use results of the other time
management processes (activity definition, sequencing, estimating) to
determine the start and end date of the project
Determines the planned start and completion dates for each activity listed
on the WBS
,Schedule Development deliverable - 🧠 ANSWER ✔✔project schedule
Tools used for schedule development - 🧠 ANSWER ✔✔o PERT
o Critical Path Method (CPM)
o Critical Chain Method (CCM)
o Resource Leveling
Schedule Benefits - 🧠 ANSWER ✔✔· Creates a consistent framework
which can be followed from project to project and during the execution of
the project
· Illustrates the interdependencies of each activity on the WBS
· Facilitates communication within the project team and between the team
and stakeholders
· Aides in the identification of "Critical" activities
· Aides the project manager to evaluate all alternatives and their impact
when making scheduling changes during the project
· Reduces the amount of resource scheduling conflicts
· Provides visibility to those tasks that can or must be run in parallel to keep
the project on track
,· Facilitates "what if" analysis (Mandatory/discretionary activities)
The Program Evaluation and Review Technique (PERT) - 🧠 ANSWER ✔✔·
Developed by the U.S. Navy in cooperation with the consulting firm Booz-
Allen Hamilton for the Polaris missile/submarine project in 1958 to help
organize the activities of 11,000+ contractors
· Uses a weighted average approach or beta probability distribution to
capture the three-point estimates discussed in previous lecture (optimistic,
most likely, and pessimistic) for activity duration
· The weighted averages for each activity are added to the network
diagram to show the start dates and finish dates for each and the final
project end date
Critical Path Method (CPM) - 🧠 ANSWER ✔✔· Uses the sequence and
duration of activities to determine the total project duration
· A critical path for a project is the series of activities that determines the
earliest time by which the project can be completed
· Produces two key pieces of information:
1) the amount of slack or also referred to as float for each activity in the
schedule and

3
, 2) the longest path through the schedule or said another way - the shortest
time the project can be completed
Slack - 🧠 ANSWER ✔✔· The difference between the earliest time an
activity can begin and the latest time an activity can begin without changing
the completion date of the project
· In most projects of any size, there is typically one critical path which
means that all of the other paths have tasks with slack but,
o Theoretically a project can have multiple critical paths
Free Slack - 🧠 ANSWER ✔✔The difference between the earliest time an
activity can begin and the latest time an activity can begin without changing
the completion date of any successor task
2 Method to Finding the Critical Path - 🧠 ANSWER ✔✔1. Calculate slack for
each activity on the WBS using a network diagram, or
2. Find the longest path through the network diagram
Calculating ES, EF, LS, LF - 🧠 ANSWER ✔✔· The calculation is performed
for each activity in two passes through the entire network diagram for each
path
