[Maham]

tell me kya mera sawal thk ja rha hy 

[Syed Awais Ali Shah Kazmi]

The following formulas will be used for the following examples.

PV = Planned Completion (%) * BAC

EV = Actual Completion (%) * BAC

CPI = EV/AC

SPI = EV/PV

Earned Value Analysis Example 1

Suppose you have a budgeted cost of a project at $900,000. The project is to be completed in 9 months. After a month, you have completed 10 percent of the project at a total expense of $100,000. The planned completion should have been 15 percent.

Now, let’s see how healthy the project is by computing the CPI and SPI.

From the scenario, you can extract the following:

• BAC = $900,000
• AC = $100,000

The Planned Value (PV) and Earned Value (EV) can then be computed as follows:

• Planned Value = Planned Completion (%) * BAC = 15% * $ 900,000 = $ 135,000
• Earned Value = Actual Completion (%) * BAC = 10% * $ 900,000 = $ 90,000

Compute the earned value variances:

• Cost Performance Index (CPI) = EV / AC = $90,000 / $100,000 = 0.90. This means for every $1 spent, the project is producing only 90 cents in work.
• Schedule Performance Index (SPI) = EV / PV = $90,000 / $135,000 = 0.67. This means for every estimated hour of work, the project team is completing only 0.67 hours (approximately 40 minutes).

Interpretation: Since both Cost Performance Index (CPI index) and Schedule Performance Index (SPI index) are less than 1, it means that the project is over budget and behind schedule. This example project is in major trouble and corrective action needs to be taken. Risks management needs to kick-in.

Earned Value Analysis – Example 2

Suppose you are managing a software development project. The project is expected to be completed in 8 months at a cost of $10,000 per month. After 2 months, you realize that the project is 30 percent completed at a cost of $40,000. You need to determine whether the project is on-time and on-budget after 2 months.

Step 1: Calculate the Planned Value (PV) and Earned Value (EV)

From the scenario,

• Budget at Completion (BAC) = $10,000 * 8 = $80,000
• Actual Cost (AC) = $40,000
• Planned Completion = 2/8 = 25%
• Actual Completion = 30%

Therefore,

• Planned Value = Planned Completion (%) * BAC = 25% * $ 80,000 = $ 20,000
• Earned Value = Actual Completion (%) * BAC = 30% * $ 80,000 = $ 24,000

Step 2: Compute the Cost Performance Index (CPI) and Schedule Performance Index (SPI)

• Cost Performance Index (CPI) = EV / AC = $24,000 / $40,000 = 0.6
• Schedule Performance Index (SPI) = EV / PV = $24,000 / $20,000 = 1.2

In dono example me Actual cost question me hi dedi gai hai.
Assignment k question me actual cost nahi di gai 

[Sajid]

nabeel ur right ya AC dia he ni tu find kasy karian gay 

[иαвєєℓ αнмє∂]

ji han lekin ab humny kar liya hai find Jazak Allah Khair. Eid Mubarak

[иαвєєℓ αнмє∂]

Question # 02
Answer
EV = 150000 * 15 / 100 = 22500
PV = 150000 * 20 / 100 = 30000
AC = 150000 * 15 / 100 = 22500
Note AC and EV are same
SPI = EV / PV = 22500 / 30000 = 0.75 If the SPI is less than 1, it means the project is behind schedule.Handouts page # 41  

CPI = EV / AC = 22500 / 22500 = 1 If the CPI is equal to 1, it means the project is as per the planned budget. Handouts page # 41  
Note: This is idea solution

[Waheed Munawar shah]

Asslam u Alikum.Koi Allah ka bnda ya bndi solution share kr de plzzz

[BS SE 5th smstr]

Nabeel bhae ye solution done h?

[иαвєєℓ αнмє∂]

ji done hai lekin yeh idea hai baki aap net par search karen "if actual value and earned value same" 

[Amjad Shahzad]

koi complate he solution send kar do

[KHALIL UR REHMAN]

SPI = EV / PV = 22,500 / 30,000 = 1.333
Hnadouts page # 41 
If the SPI is greater than 1, it means the project is ahead of schedule.

CPI = EV / AC = 22,500 / 22,500 = 0
Hnadouts page # 41
If the CPI is less than 1, it means the project is over budget.

 

ye dono answer wrong lag ry ha han. use calculator and see?
