3. Question A paper (≤ 2 pages) briefly describing how a software development methodology impacts the team’s GQM definitions. Reporting of actual individual effort log data to Director by team, along with brief analysis

4. Answer 1. COMPARE TWO METHODOLOGIES: TRADITIONAL VS AGILE 2. COMPARE MEASUREMENT IN TWO METHODOLOGIES: TRADITIONAL VS AGILE 3. SOFTWARE DEVELOPMENT METHODOLOGY IMPACTS THE TEAM’S GQM DEFINITIONS.

5. 1. COMPARE TWO METHODOLOGIES: TRADITIONAL VS AGILE TraditionalAgile  Assume that requirements can be known  at the start of the project  Product Owner/User involvement with development team is minimal after requirements are approved  Schedule, budget, architecture and design for entire project can be created “up front” given requirements  Change managed formally. Rework is bad  Lots of documentation  At the end project, Customer will be see product following their requirement.  Assume that requirements will emerge  Product Owner/User works closely with development team on a daily basis  Schedule, budget, architecture and design for project evolve as requirements emerge  Change is managed informally, Rework (refactoring) is good  A few Document  Product built so you always have a working system and can “release” at any time.

6. 2. COMPARE MEASUREMENT IN TWO METHODOLOGIES: TRADITIONAL VS AGILE

7. 3. SOFTWARE DEVELOPMENT METHODOLOGY IMPACTS THE TEAM’S GQM DEFINITIONS. TraditionalAgile Schedul e Description In traditional, Schedule will be upfront and we will consider actual schedule in schedule Plan. Schedule following user stories, when customer gives more stories, then Schedule will longer. They’re proportional. Goal Measureme nt Big plan up front & earned value Burn Down Charts Question - How much Budgeted Cost of Work Scheduled is there? - How much Budgeted Cost of Work Performance is there? - How much is the estimate schedule of each sprint? - How much is the actual schedule of each sprint? What is the estimated versus the actual schedule for each release? Metric - Schedule Variance SPI Schedule Variance in each sprint

8. 3. SOFTWARE DEVELOPMENT METHODOLOGY IMPACTS THE TEAM’S GQM DEFINITIONS. Cost Description Scope (requirements - features) is well understood and can be fully defined at the start of a project. Therefore, we measure cost for all activities in traditional project. In Agile project, we start the project by ambiguous scope. So members have to discover requirements throughout the project. Therefore, we cannot understand fully activity in the agile project. We can only measure based on features that we understand in agile project. Goal Measureme nt Big plan up front & earned valueBurn up Charts Question - How much is the estimate cost of each activity? - How much is the estimate cost of each release? - How much is the actual cost for each activity? - How much is the actual cost of each release? - What is the estimated versus the actual cost for each activity? - How much is the estimate cost of each sprint? - How much is the actual cost of each sprint? - How much is the budget planned of the release? - How much is the actual cost of the release? What is the estimated versus the actual cost for each release? Metric - Cost Variance CPI - Cost Variance in each sprint. - Cost Variance in each release.

9. 3. SOFTWARE DEVELOPMENT METHODOLOGY IMPACTS THE TEAM’S GQM DEFINITIONS. Require ment Explain In traditional natural, Requirement is the first phase in life cycle, and output of this phase is input of that phase, if this phase is not clearly, you will spend expensive cost to rework. So Requirement phase very important and be carefully. Agile only base on stories of customer and do product in sprint and consider with customer. Agile is not care requirement clearly. Goal Measure ment Managing requirement clearly Feedback customer after Each sprint Questio n - How many requirements is the project? - How many requirement is the project‘s customer acceptance. - How many requirements change is the project? Frequency of each change? - How many requirements are there traced? - How many Stories acceptant are there in project? How many Stories are there in project? Metric - % requirements change. - % requirements acceptance of customer. - # Change of each requirement change. % number Requirements traced. % stories acceptant of customer.
