1.9 Quality Management

Management of software quality is increasingly important because the safety, security, and welfare of the
general public are increasingly dependent on software.

Each of the deliverable work products should have acceptable quality, as determined by the needs of the users
and other stakeholders. Management of quality assurance, quality control, verification, and validation are important
elements of managing software projects.

Software quality attributes that are important to users and other stakeholders include, but are not limited to
attributes such as:
s Safety,

s Security,
s Reliability,

s Resilience,
s Dependability,

s Scalability,
s Performance,
s Ease of learning,

s Ease of use (usability),
s Interpretation of error messages,

s Availability,
s Accessibility,

s Efficiency,
s Flexibility,
s Interoperability, and

s Robustness.
Software quality attributes that are important to software developers include, but are not limited to:

s Testability,
s Maintainability,

s Portability,
s Extensibility, and

s Reusability.
