Question 4- Determine the critical pat associated with the following project network diagram a. ADG b. BEG C. There is no critical path 3 F 10 7 D 11 a. 1 b, 2 C. 3 Question 5. How many days can task B be delayed without delaying completion of the project 5 G 3 C E 6 10

Solution

1.Padding is extra time added to a schedule that you don’t really think you need but that you add just to feel confident in the estimate.

pessimistic (P) estimate which is the amount of work the task might take if the negative factors they identified do occur.

Single point estimates don’t accurately represent the natural variation in a task. A range estimate of low and high is a good first step to improve accuracy. With a little definition and some simple math, range estimates can be used to much more accurately and responsibly estimate a project.

answer: range of values.

2.

Task deifinition: a task is an activity that needs to be accomplished within adefined period of time or by a deadline . A task can be broken down into assignments which should also have a defined start and end date or a deadline for completion.

Task sequencing: act of sequencing tasks and creating a logical relationship between them.

schedule estimation:Estimating start and stop date of activities(tasks)

answer : schedule estimation must be done at last
