Sample text

Numbers talk! Similarly, software engineering practitioners often like to see a study that supports the benefits of a new practice before they change the way they engineer systems. Those of you familiar with music will understand the concept of an etude. An etude is a musical composition written solely to improve technique. At the XP Universe conference in 2001, Kent Beck, the originator of Extreme Programming (XP) [3] likened learning software best practices to etudes in music. When he was learning to play a musical instrument, he was given etudes – short scores of music – to play over and over and over again.

3. Software requirements change is inevitable. However, the requirements of some software are not so volatile. Give three examples of such software. What are the characteristics of this kind of software? 4. For a commercial shrink-wrapped software product, what are the important goals the software developers seek to achieve? List at least 5 items, and rank them in order. 5. Search the web, and find three software process models. Give some description for each model. 6. Based on Baber’s definition about engineering and your personal experience, do you think software is engineering?

At 8 hours/defect, each person can only remove 5 defects per 40 hour week). In 12 weeks, this team could only remove: (12 weeks)(10 people)(5 defects/week) = 600 defects This means that 2,500 – 600 defects = 1,900 defects would escape to the customer. Scenario Two: Solo Programming with Inspection or Pair Programming without Inspection These cases are shown in the top and bottom diagrams of Figure 1. For the sake of this example, we will assume that pair programmers produce code of equal quality to reviewed code, though there are no research results to back up this claim.
