SOME QUERIES RELATED TO GQM

The objective is to identify how you can save $3000 in one year. This will allow you to purchase a personal computer. However, it is not possible to earn additional money. Your income will be exactly the same as last year. You will have to find cost savings. Sources of data are, for example, your agenda, bank notes and salary receipts.

1. Define the GQM goal for this measurement program according to the GQM goal template.

          To save $3000 within one year for purchasing a new personal computer will be the goal of the Goal-Question Metric.

2. Define a set of GQM questions related to the measurement goal.

Q1	What was the salary amount?
Q2	What are the expenditures done with the received salary?
Q3	After the expenditure done, what will be the left amount with me?
Q4	What was the amount to be saved?

3. Check and improve these questions according to the criteria of good GQM questions given in step 4.

Q1	What will be the amount used for regular personal needs?
Q2	What will be the amount left (saved) with me after all the expenditures done?

4. Refine your GQM Questions into metrics. Make a distinction between direct and indirect metrics.

Q1. What will be the amount used for regular personal needs?

          M1: Total salary credited

          M2: After spending for all the important expenditures, the left amount

Q2. What will be the amount left (saved) with me after all the expenditures done?

          M1: The savings money.

          M2: The amount going to be spend on buying personal computer.

DIRECT METRICS	INDIRECT METRICS
Totally $3000 is going to be saved this year.	Amount of money saved per month. (Amount saved per year / 12)
Total amount of money spend on grocery.	Expenses spend per month. (Expenses per year /  12)
Total money spend for my personal use.	Savings done per month. (Saving spend year / 12)

5. If possible list your hypotheses regarding your questions (or metrics) and carry out some trial measurements from historical data to test the GQM tree you have established.

Hypothesis:

	Yearly	Monthly
Total salary	$60000	$5000
Expenses on grocery	$18000	$1500
Daily expenses	$6000	$500
Expenses on health	$1200	$100
Expenses on fuel	$12000	$1000
Other expenses	$3000	$250
Personal expenses	$16800	$1400
Money saved	$3000	$250
