Software Development Project Worksheet Assignments | College Homework Help

1.

The problems for this week are 11.1, 11.2 and 11.3. This assignment must be in Excel QM (network diagrams can be in Excel or hand drawn and scanned) and submitted through the Assignment.

11.1) Consider the project with the following estimates for activity times and precedence relationships:

Activity Optimistic

Time

Most

Likely Time

Pessimistic

Time

Immediate

Predecessor(s)

A 3 4 5
B 5 7 9
C 2 3 10 A
D 2 5 8 B
E 1 7 7 B
F 3 5 7 C, D
G 7 8 9 D, E
H 2 6 10 F

(a) What is the expected duration of the project?

(b) What is the project variance?

(c) If the deadline of the project is 25 days, what is the probability of finishing the project on time?

11.2) A small software development project has five major activities. The times are estimated and provided in the table below.

Activity Immediate

Predecessor

a m b
A 2 5 8
B 10 10 10
C A 4 7 10
D B 2 5 14
E C 3 3 3

(a) What is the expected completion time for this project?

(b) What variance would be used in finding probabilities of finishing by a certain time?

(c) Draw a network diagram for the project.

11.3) Given (Time in weeks):

Activity Optimistic Most Likely Pessimistic
A 3 4 5
B 6 7 14
C 2 3 10
D 6 9 12
E 4 5 12
F 1 3 11
G 1 2 9
H 2 5 8
I 1 4 7

Review the network diagram (see attached) to answer this question.

Determine:

(a) the critical path.

(b) the probability that the project will be completed in 22 weeks.
