possible mechanisms to reduce
project delays:
3
4
5
Which of the following is the
emphasis of the CCPM in a
project duration:
Which of the following statements
best describes the project buffer:

Which of the following statements
best describes the feeding buffer:

Critical Chain Project
Management builds schedules
using which of the following:
Correct Answer
Improve critical
chain stability and
increase the
probability of
achieving a
promised project
duration
The theory of
constraints
Don’t allow
multitasking and
resources
interruptions
Resource
behavior
A .safety margin
that acts as a
protection of the
project due date
Extra times placed
whenever a non
critical activity
joins the critical
chain
The size of the
project buffer can
depend on the
desired probability
for completing the
project schedule
Finished to start
(FS)
Distractor 1
Improve the
product quality
Distractor 2
Trade off between
risks and benefits
Distractor 3
Ensure cost
,quality and
schedule were
met as expected

Extra times put in
the critical path
Increase of project
duration by 10%
Increase of project
budget by 10%
2
Extra times put in
the beginning of
each task
Extra times placed
in every critical
task
Extra times placed
at the beginning of
the execution
phase
2
The size of the
project buffer
should be
adequately
determined based
on the scope
complexity
Start to finish (SF)
The size of the
project buffer can
depend on the
time to market
requirement
The size of the
project buffer can
never be
determined
because of too
many uncertainty
