السلام عليكم ورحمة الله وبركاته

الاخوان الكرام ممكن نتعاون في حل الاسئلة وان شاء الله يكون اسهل علينا نعدل على الحل من البحث عن الحل

وشكرا لكم جميعا

Q 1: Using Gantt chart you created for “Hospital Management Project ", Add at least four milestones and enter dependencies between tasks using Microsoft Project.

Q 2 : Assume you have completed three months of the project. The budget at completion (BAC) was $200,000 for this six month project. Also assume the following:
Planned value (PV) =$120,000
Earned value (EV) =$100,000
Actual cost (AC) = $90,000
a) What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?

b). How is the project doing? Is it ahead of schedule or behind schedule? Is it under budget or over budget?

c). Use the cost performance (CPI) to calculate the estimate at completion (EAC) for this project. Is the project performing better or worse than planned?

Q3. Consider the following tasks shown in table below :
Task Predecessors Expected Time
A - 5
B - 4
C A 6
D A 3
E B 3
F B 6
G E 2
H F 5
I C, D 8
J G, H, I 5

A- Draw project Network to represent the above table ?

B- What is the critical path ?

C- Show for each task ?

حل السؤال الثاني:

a- Cost variance (CV) = Earned Value (EV) – Actual Cost (AC)
CV = $100,000 - $ 90,000 = $ 10,000
CV = $10,000

Schedule variance (SC) = Earned Value (EV) – Planned Value (PV)
SC = $100,000 - $120,000
SC = - $20,000

Cost performance index (CPI) = EV – Actual cost (AC)
CPI = $100,000 - $90,000
CPI = 1.11

Schedule performance index (SPI) = EV % PV
SPI = 100,000 % 120,000
SPI = 0.83

b- As the cost variance (CV) is a positive number $10,000 therefore it is under budget and it means that performing the work cost less than planned. Schedule variance (SV) is a negative number – $ 200,000 it means that it took longer time than planned to perform work. So the project is behind the schedule. The project is behind schedule and the budget is costing less than planned till this stage of the project.

c- The Budge at completion (BAC) was = $200,000
Estimate to complete (ETC) = (BAC – EV) / CPI
= (200,000 – 100,000) / 1.11
= $ 90,090
EAC = AC + ETC
= 90,000 + 90, 90
= $180,090
As the EAC under budget at $19,910, the project will be completed under the budget.
