For this unit topic, find one of the "requirements engineering" activities described in the book, and research it online. You should be able to answer the following:

• How this activity helps me reach my class goal? For example, if your goal is to learn about mobile software engineering, answer how is your chosen activity applied in mobile technology. Is there something special done for mobile, as opposed to Web software?
• What do we do as part of such activity?
• Why is such activity necessary?
• Is it always required, across all different software process models (Waterfall, Agile, Spiral, etc.), or can we bypass it depending on the scenario?

Again, summarize your findings, and don't forget to add your external reference(s) link so I can all read it.
