A working day is Monday, Tuesday, Wednesday, Thursday and Friday (8am - 4pm).? Staff works Mondays through Friday.? Project start date is 1st April, 2016.? The last Friday of every month is a sports day for the company. No work is done on this day.? The following holidays are observed in a year.o January 1 - Another Wacky Year Dayo Second Monday in January, March, May, June, August, October, December is Eat-All-You-Can dayo April 10 - Plagiarism Dayo May 24 - National Panic Dayo June 18 - Love Your Neighbor Dayo August 15 - National Rocky Road Day o December 20th - Blame Someone Else Dayo If a holiday falls on a Saturday then Friday will be given as an extra day off, and if it falls on a Sunday then Monday will be given as a day off.Given the information provided in Table 1 and key notes, answer the following.
Required:
i. Using an appropriate approach to building a Work Breakdown Structure (WBS), develop a graphical WBS for this project.
ii. Using the 3-point technique, calculate the activity durations (round to nearest whole number).
iii. You are tasked to draw using appropriate software an AOA PERT chart for the above project; assuming a finish-start (FS) relationship between activities. (The length of the arrows must be indicative of the duration).
iv. How long will this project take? What is the completion date?
v. List all the distinct paths in the project along with their durations.
vi. Which tasks are on the critical path of the PERT chart above?
vii. Identify all Activities in the above project that have a slack and the amount of slack.
viii. You have discovered that the competing accounting package (with significant improvements) is scheduled for delivery in approximately 144 days. Based on your original schedule above, would you beat this delivery time? If not, what actions would you take?
ix. One of your two critical systems analysts might be leaving the firm sighting critical family reasons. What actions would you take to ensure the original delivery time is still met?
x. The person working on activity 15 informs you he can't start work until two days after the scheduled starting date. What impact would this have on the completion date of the project?
xi. By how many days can activity 17 be delayed before it becomes critical?
xii. If activity 19 is delayed by 4 days what will be the new project duration? If there is no effect, state ‘No change in duration'.
xiii. Convert the above AOA Chart to an AON Chart (also known as Project Network Diagram) clearly stating the ES, EF, LS, and LF for each of the activities. Use the following node style for your AON diagram. Consider the SS relation between activities 21 and 24.
xiv. Create a Gantt chart for the above network schedule using project management software.
xv. Complicating the issue is the concern about the project meeting the promised delivery dates. How could the project manager convince their clients that they should wait for this product rather than jump to a package provided by a new entrant in the business?
