<p>Need some help with a PERT/CPM problem. I have a table and the Given/Task scenario I attached a link to get the files, it would not fit into the question box due to charactor length. Table 1.1 in the attached worksheet “PERT/CPM Tables” shows three estimates of the time it will take Company A to complete each of the activities and project tasks in the customer-feedback system project (optimistic, probable, pessimistic).</p><p>2 ATTACHEMENTS: <a href="http://www.mediafire.com/file/2niwg5rkx1d/Task%2520309.3.2-01-06.pdf">http://www.mediafire.com/file/2niwg5rkx1d/Task%2520309.3.2-01-06.pdf</a></p><p>http://www.mediafire.com/file/cuzdwttztjk/309_3_2-01-06_PERT_CPM_Tables_TSRPF_(2)(1).xls</p>

Doing Chartered Accountancy
Please revise? Calculations are a little off, below are the problems with the problem, but I can't figure out what the error is.
A2. PERT Chart
The PERT is correct. However, the critical path is not shown.
A4. Probability of Completing on Time
The work shown thus far is correct, but this is not the final result. Please reconsider final step(s).
C1. Activities to Be Crashed
Two of the tasks listed in this response are correct. Which two?
C2. Number of Weeks to Crash
Please revise based on the corrections to C1.
D. Least Increase in Cost
Though the response of 8834 is technically correct, the work shown does not support this response. Please revise once C1 and C2 are corrected and place close attention to units of measure.

<p>VERY close, everything else factors correctly, but there is one minor detail that needs correction in the Probability of Completing on Time section, I got this feedback:</p><p>"The .0793 or 7.93% achieved is correct. However, this must be added to something else to achieve the correct probability. Please reconsider."</p><p>I am not sure exactly what they are referring to, was hoping you might know. Not sure if it is a terminology thing or what. </p><p> </p><p>Thank you SO much for helping me with this! I will gladly pay for another full amount when complete. I could never have figured this one out without you.</p>
I am sure that the 0.5 to be used, but not sure whether to add or subtract .0793 from 0.5.
My mentor gave me an example. He said the .0793 or 7.93% is correct, it is something else.....
QAT1 Task 4
Calculating probability of completion by week Y
Consider a project that has a critical path of A, F, H, K and an expected time, E(T) = 20 weeks.
The variances for each activity are: 12ÏƒA2=1.5;ÏƒF2=2.25;ÏƒH2=1.25;ÏƒK2=4' type="#_x0000_t75">.
Your boss wants you to calculate the probability the project will be complete in Y = 24 weeks.
I am lost, was hoping it might make sense to you.
It means that we should add .5 to .0793 to make it .5793 it means that probability is around 58%
Wondering if you might be willing to look at this problem and let me know if you could do it for me. I was thinking $100.00?
I didn't want to post it for just anyone and was hoping it might be something you would do. Let me know if you are interested and if so, do I need to post it or do it through here or............
I appreciate your confidence in me. But I am really sorry that I will not be able to do the question, It is better you list so other expert may help you. However in future you may ask me and I will try to help you out. Take care.
