Product definition
is an artifact, is quantifiable, and can be either an end item in itself or a component item. Additional words for products are materials and goods.
Triangular & Beta distribution
Used to calculate activity duration, use three estimates. Expected Duration = (O + M + P)/3
1) Optimistic Estimate
2) Pessimistic Estimate
3) Most Likely Estimate
PERT
Program Evaluation and Review Technique
Most likely estimate by giving weightage
Expected Duration = (O +4M + P)/6
Low standard deviation and High standard deviation
Low: data points are close to the mean of the data set (average)
High: data points are spread out across the board
Standard deviation equation
SD= (Pessimistic Value - Optimistic value)/6
Variance equation
SD^2
standard deviation squared
Critical Path
Longest path duration
Has zero float so activities on it will also have zero float
Total Float
The amount of time the tasks on the non-critical path can be delayed without affecting the project schedule ; also known as float or slack
Late finish - early finish
Free Float
the amount of time that an activity is delayed by without affecting the early start of the next activity
Free Float of Activity X = Early start of next activity - early finish of activity x - 1
Early Start
the earliest time when an activity can be started
Early Finish
The earliest time when an activity can be completed
Late Start
The latest time when an activity can be started
Late Finish
The latest time when an activity can be completed
Activity Duration & equation
the amount of time taken by an activity on a network diagram to complete itself
Duration = early finish - early start + 1
OR
Duration = late finish - late start + 1
The precedence diagram activities have four types of dependencies, what are they?
Start to Finish - The second activity cannot be finished until the first activity starts (least common)
Finish to Start - The next activity cannot be started until the first completes (most common)
Start to Start - the second activity cannot start until the first activity starts, both start simultaneously
Finish to Finish - the second activity cannot finish until the first activity finishes, both finish simultaneous
Schedule Variance
tells you whether you are ahead or behind of schedule.
SV = Earned Value - Planned Value
If a schedule variance is positive you are…
ahead of schedule
If a schedule variance is negative you are
behind schedule
If a schedule variance is 1 you are _ When a project is completed the schedule variance becomes _
on schedule
zero
Cost Variance
tells you whether you are under budget or over budget
CV = Earned Value - Actual Cost
If a cost variance is positive you are
over budget
If a cost variance is negative you are
under budget
If a cost variance is zero you are
on budget
Schedule Performance Index
Tells you how efficiently you are progressing compared to planned progress
SPI = Earned Value/ Planned Value
