PRIMAVERA QUESTIONS
Q1:What are the difference between free float, total float and what is different
between Float and Slack? - Answer- Free Float : amount of time , an activity can be
delayed without delaying the successor activity
Total Float : amount of time , an activity can be delayed without delaying the project
finish date
Float and slack are the two different words for the same meaning.
Q2:What is a constraint in primavera? - Answer- Constrains in primavera is to fix the
early or late start or finish date of an activity as per following options:
1) Project Must Finish by
2) Mandatory Start / Mandatory Finish
3) Start / Finish On or After
4) Start / Finish On or Before
5) Start / Finish On
6) Expected Finish
Q3:How can you define the Critical Path in primavera? - Answer- The sequence of
activities which describe the longest path from the data date to the end of the project.
In a schedule without any constraints, this will be all activities with zero total float.
(if you have constrains which force negative float, simply filtering on total float equal
to or less than zero can bring up activities which are not on the critical path)
Q4:What is WBS? - Answer- WBS means Work Breakdown Structure. it represents a
hierarchical breakdown of a Project into elements and deliverables.
Q5:What is an open end activity in primavera? - Answer- The open end activity is the
activity that does not have any successor. Normally open end activity is not accepted
in schedule because the total float will be calculate from the end of the project and
these entire activities late dates gather at the end of the project and can not be
prepare a logical late start plan.
Q6:What is the difference between Retained Logic & Override Logic in progress
update? - Answer- If a project is generally running according to plan and activities
are not progressed out of sequence then there will be virtually no difference between
the two methods. BIG differences come when activities are progressed out of
sequence.
,I believe in retained logic. Invariably that will produce the longest critical path but if
activities have been progressed out of sequence, there could be some resulting
illogical dependencies remaining, in particular resulting from dependencies with
durations.
Progress override invariably produces a shorter critical path and again there could
be some illogical lack of dependencies resulting from activities having been
progressed out of sequence.
Q7:How do u measure & compare the progress using primavera? - Answer-
Progress is measured primarily against the baseline. If the baseline has been loaded
with cost and/or resources, earned value management can be used for this purpose.
If not, progress is measured as variance to baseline dates.
Budget at Completion (BAC)
Planned Value (PV) = budget at Completion (BAC) x Planned % Complete
Earned Value (EV) = budget at Completion (BAC) x Actual% Complete
Actual Cost (AC) = No formula What you've actually spent on the project
Schedule Performance Index (SPl) =Earned Value (EV) / Planned Value (PV)
Schedule Variance (SV) =Earned Value (EV) - Planned Value (PV)
Cost Performance Index (CPI) =Earned Value (EV) / Actual Cost (AC)
To Complete Performance Index (TCPI) =(Budget at Completion (BAC) - Earned
Value (EV) ) / (Budget at Completion (BAC) -Actual Cost (AC) )
Cost Variance (CV) = Earned Value (EV) -Actual Cost (AC)
Q8:What is resource allocation and resource leveling? - Answer- Resource allocation
is assigning resources to activities,determine the amount of labor, equipment and
money required for any activity.
Resource leveling is Resource requirements of all scheduled activities are compared
to the maximum quantity available at the time of leveling.An activity is delayed if too
few resources are available at any time during the activity's duration.The maximum
quantity for a resource is determined through the Max units/time for a particular
resource in the Resources Tab.
Q9:What is an S - Curve and how to create S Curve in primavera? - Answer- An S-
curve is a graph showing cumulative cost or value (measured in terms of money or
manhours) against time. On a typical project, these graphs follow an "S" shape,
hence the name. Typical data to be plotted on an S-Curve includes:
Actual Cost (ACWP)
Planned Value (BCWS) -Early dates
Planned Value (BCWS) -Late dates
Earned Value (BCWP)
Forecast Value -Early dates
Forecast value -Late dates
Forecast Cost -Early dates
, Forecast cost -Late dates
Q10:What are the difference between flag and milestone activity in primavera? -
Answer- Mile stone & flags both are events rather then activities. Some client likes to
use flags rather than mile stone due the following differences.
1- With the use of flags the logic of main event can be easily tracked as these can
not be created without predecessor as stand alone allocating the constraint.Where
as mile stone can.
2- Flags can not update manually as Primavera automatically update the status
where as milestone can be update manually.
3- Flags can not be constraint only driven by predecessor where as milestone can.
Q. What is an S - Curve and how to create S Curve in PRIMAVERA? - Answer- An
S-curve is the cumulative cost function plotted on a histogram, which can vaguely
resemble the letter S. BCWS, BCWP, and ACWP are frequently plotted and
compared on a histogram as separate and "shadowing" S-curves.
Use the Activity Usage Profile to view cost or unit values for activities in the open
project over time according to a timescale you specify. The Activity Usage Profile
displays resource allocations for all activities or for the activities you select in the
Activity Table, Activity Usage Spreadsheet, Gantt Chart, or the Activity Network.
Q. What are the early warning signs you look for when reviewing progress against a
schedule? - Answer- Despite many efforts a schedule can quickly spiral out of
control and this will determine if they have a plan to minimize avoidable gaps and
delays.
Q. What is a good use of lag on a project? - Answer- Find out if your potential
scheduler knows proven best practices in planning and scheduling. Proven best
practices across construction discourage any use of LAG OR LEAD TIME on
projects.
Q. If given someone else's schedule, how would you go about analyzing it? -
Answer- You'll discover how your candidate breaks large tasks into manageable
pieces and how they deal with abiguity. Are they confident enough to ask for help on
the pieces that fall outside their expertise? Do they have a system to follow for
analyzing outside schedules? WE DO.
Q. How do you communicate the monthly schedule analysis? - Answer-
