BSA385 Intro to Software Engineering

Week 1 Discussion

DQ1 Software Development Phases

As you read in Ch. 4, "Software Process Models," of Essentials of Software Engineering, there are several models used in software development. The phases of requirements, design, implementation, test, and maintenance are executed differently in the Waterfall versus a multiple-components incremental model.

Describe how the phases are executed differently in these two models, and discuss an advantage you see in using one over the other if you were a software engineer designing a mobile application.

DQ2 “Functional” and “Non-Functional” Requirements

In Ch. 1, "Creating a Program," of Essentials of Software Engineering, you examined how program requirements statements that define and qualify the program are essential to the software development process. How would you explain what the word "requirements" means to someone trying to make decisions about what they truly need from a program?

Explain, in non-technical terms, what the differences are between "functional" and "non-functional" requirements.
