Requirements engineering (the elicitation, documentation and validation of requirements) is a fundamental aspect of software development. Unfortunately, and to the detriment of everyone involved, requirements engineering efforts are often shortchanged or even completely forgone in order to expedite the code writing process. Engage in problem solving and write a paper that includes the following: 1. An evaluation of requirement patterns for a problem associated with software associated with the mobile phone. 2. An assessment of which problem solving techniques were of the most effect. 3. A display of a visual taxonomy with a descriptive explanation of the patterns. 4. An explanation of how these patterns that were identified are related to each other. References: 5 or more.
