a. tuckman’s ladder
b. parkinson’s law
c. progressive elaboration
d. enterprise environmental factors

Answer 1

c. progressive elaboration

Question 2

The lowest level of decomposition in the WBS is called

a. a task
b. an activity
c. a deliverable
d. a work package

Answer 2

d. a work package

Question 3

in precedence diagram method, a lag refers to

a. a fixed delay imposed on a predecessor
b. a conditional delay caused by uncertainty
c. the amount of time a successor can be initiated in advance
d. a slow moving resource

Answer 3

a. a fixed delay imposed on a predecessor

Question 4

match the following
finish to start
start to start
finish to finish
start to finish

1. predecessor may not finish until the successor starts
2. successor may not finish until the predecessor is complete
3. successor may not start until the predecessor is complete
4. successor may not start until the predecessor starts

Answer 4

finish to start - 3
start to start - 4
finish to finish - 2
start to finish - 1

Question 5

what is cost variance?

Answer 5

earned value - actual cost

CV = EV - AC

Question 6

which is NOT among the tools and techniques of the estimate costs process?

a. alternative analysis
b. reserve analysis
c. cost of quality
d. funding limit reconciliation

Answer 6

d. funding limit reconciliation

Question 7

a project has a budge of $20K. the planned value is currently $6K. the project is 25% complete and $6K has been spent. which statement is correct

a. the project is behind schedule
b. the project is ahead of schedule
c. the project is on schedule
d. the project is under budget

Answer 7

a. the project is behind schedule

planned value (PV) = $6k
earned value (EV) = $20K x 25% = $5K
schedule variance (SV) = EV - PV = $5K - $6k = -$1K
SV < 0 means behind schedule

Question 8

outputs of the control costs process include

a. work performance information, cost forecasts, and change requests
b. work performance data, cost estimates and project funding requirements
c. work packages, cost baseline and reserve analysis
d. work breakdown structure, cost aggregation and funding limit reconciliation

Answer 8

a. work performance information, cost forecasts, and change requests

Question 9

Given the following factors
earned value = $14K
planned value = $15K
actual costs = $12K
what is cost variance?

a. $0
b. $1K
c. $2K
d. $3K

Answer 9

c. $2K

cost variance (CV) - EV - AC = $14k - $12k = $2k

flow chart
checksheets
pareto chart
histogram

scatter diagram

1. record measurements relative to upper and lower control limits
2. perform root cause analysis
3. data representation of statistical distribution
4. identify the most common causes
5. determine the correlation of 2 variables
6. record variables and attributes during inspection
7. illustrate how various elements interrelate

Answer 10

fishbone diagram - 2
flow chart - 7
checksheets - 6
pareto chart - 4
histogram - 3
control chart - 1
scatter diagram - 5
