MAN 4583 EXAM 2 QUESTIONS AND VERIFIED
ANSWERS
WBS breaks down into ____ rather than ___ - Answers - deliverables; activities
when defining work activities it is essential to involve - Answers - the people who will
actually be performing the project work
how do you define a work activity - Answers - give activity a name; short & starts with a
verb
Sequencing work activities - Answers - put work activities in a logical order
you should sequence activities so that they are done - Answers - ASAP
Who should create estimates for activity durations - Answers - those who will be
performing the activities
overestimate time necessary to complete an activity = - Answers - slows down project
under estimate time necessary to complete an activity = - Answers - fall behind
schedule & disappoint customers/sponsors
what else should you include when estimating activity duration - Answers - assumptions
& degree of certainty & activity attributes
Node - Answers - each activity has a name, abbreviation, & estimated duration
outside 4 corners represent - Answers - ES, EF
LS, LF
float / slack - Answers - amnt of flexibility a particular activity has in the schedule ;
length of time the activity can be delayed from its ES w/o delaying project
Activities on the critical path have a float of - Answers - 0 (can't be delayed w/o delaying
the project)
First pass (forward) - Answers - shows how SOON each activity could finish (EF)
Second Pass (backwards) - Answers - shows how LATE each activity could finish &
then how late it could start
critical path - Answers - longest series of activities in the project
, float formula - Answers - LS - ES
Gantt charts are not the best way of - Answers - communicating the schedule
Mark critical path in - Answers - red/bold
mark noncritical activities in - Answers - blue/not bold
for agile projects, a person creates their schedule - Answers - one sprint at a time
RACI Chart (stands for) - Answers - responsible, accountable, consult, inform
RACI charts help to - Answers - assign activities to workers
what is the most important task in order to accurately define the duration for each
activity - Answers - developing a project schedule
3 tools to estimate activity durations - Answers - 1. analogous
2. parametric
3. 3 point estimates
Analogous Estimating (top down) - Answers - (analogies) find completed similar projects
& compare it to yours & use expert judgment to fix approximate time duration for your
current project
-quick, but not accurate
analogous estimates is useful when - Answers - there is little info available for the
project & you have to estimate ASAP
analogous estimates accuracy depends on - Answers - the degree of similarities
Parametric Estimating - Answers - uses past records to compute the duration estimate
(historical data & other parameters)
3 Point Estimates - Answers - (uses PERT)
1. most likely (Tm)
2. Optimistic (To)
3. Pessimistic (Tp)
3 Point Estimates-
Most Likely (Tm) - Answers - time taken by an activity to finish it in most cases
3 Point Estimates-
