Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Top 10 Primavera Interview questions and Model Answers:

the most common questions for primavera interview and what is the model  answer to all of them

Q1:What are the difference between free float, total float and what is different between Float and Slack?

Float and slack are the two different words for the same meaning.

Top 10 Primavera Interview questions and Model Answers

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.

Q2:What is a constraint in primavera?

Constrains in primavera is to fix the start or finish date 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?
Its the longest path through the project with the least amount of float,Filter the activities with total float equal to or less than 0

Q4:What is WBS?
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?
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?
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?
progress can be measured using EVM earned value management as per the following terms:
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)
For more information see this article:EVM earned value management

Q8:What is resource allocation and resource leveling?
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?
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.

Q10:What are the difference between flag and milestone activity in primavera?
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.

Answer no:-3 critical path activity has a minimum duration of time, in critical activity float will be zero(0) means we cant delay date of that activity because float is zero(0) mean there will not any flexibility.thats why called a Critical path activity.

Q2:What is a constraint in primavera?

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

7) ALAP

 

Q3:How can you define the Critical Path in primavera?

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)

 

Q7:How do u measure & compare the progress using primavera?

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.

Other progress measurement techniques also exist –for example Earned Schedule.

 

Q9:What is an S – Curve and how to create S Curve in primavera?

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

 

(it’s not a histogram. –A histogram is a bar graph of the in-period values. the S-curve is the line-graph of the cumulative values)
