Value-Driven Delivery

Question 1

Present Value

Answer 1

Future Value/ (1 + i)^n
i = interest rate
n = number of years

450000/(1.06)^3
for 6% interest rate

Question 2

Future Value

Answer 2

Known Value * (1 + i)^n

Known Value - what will it take to complete the project
i = interest rate
n = number of years

Question 3

Net Present Value

Answer 3

Present value of a revenue stream over a period of time

Sum of cash flows / (1 + i)^n

Question 4

Internal Rate of Return (IRR)

Answer 4

NPV of the project >= NPV of the benefits of the project

Question 5

Cost Varience

Answer 5

Earned Value - Actual Cost

Question 6

Earned Value

Answer 6

Earned Value is the amount of the task that is actually completed.

%Completed * Project total budget

Question 7

Schedule Varience

Answer 7

Earned Value - Planned Value

Question 8

Cost Performance Index (CPI)

Answer 8

Earned Value/ Actual Value

EV / AV

Question 9

Schedule Performance Index (SPI)

Answer 9

Earned Value/ Planned Value

EV / PV

Question 10

Estimate AT completion (EAC)

Answer 10

Budget at completion/ Cost Performance Index

EAC = BAC/ CPI

Question 11

Estimate TO completion

Answer 11

Estimate at completion - Actual cost

Question 12

To-Complete Performance Index

Answer 12

Effeciency needed to meet Budget At Completion (BAC)

(BAC - EV) / (BAC - AC)

Effeciency needed to meet Estimate AT completion (EAC)

(BAC - EV) / (EAC - AC)

> 1 - Hard to accomplish
= 1 - Same level of effeciency
<1 - Easy to accomplish

Question 13

EVM Rules

Answer 13

Compute Earned Value

Variance means subtract
-ve means bad variance

Index means division
< 1 bad index

Question 14

Key Performance Indicators (KPI) of Agile

Answer 14

Rate of Progress
Remaining Work
Likely completion date
Likely cost remaining

In Agile its all about getting this done
