Quality attributes are of the utmost importance to software architects because they affect architectural decisions. In this chapter, we will begin by explaining what quality attributes are, and why it is important to consider them throughout the software development life cycle. Some quality attributes can be difficult to test, so we'll explore what it takes to test them.
We will go into detail on some more common software quality attributes, such as maintainability, usability, availability, portability, interoperability, and testability. After reading this chapter, you will know the considerations that need to be taken into account for a software system to meet these quality attributes.
In this chapter, we will cover the following topics:
- Quality attributes
- Maintainability
- Usability
- Availability
- Portability
- Interoperability
- Testability
