Software Quality Lecture

Medical records are required to follow a standard data structure that can be read by other lab information systems

Software quality has many dimensions

The ability of software to perform well or achieve a result without wasted energy, resources, effort, time or money.

•The speed at which software performs under a particular load.

internal characteristics - cause for failures :an incorrect step, process in a computer program

IEEE Definition of SQ: Software quality is the degree to which the system, component or process meets

What is ISTQB

The ease with which software can be modified (adding features, enhancing features, fixing bugs, etc)

The defect management approach is based on counting and managing defects. 

ØA staff member should be able to handle at least 60 service call per day. This is what SQ dimension

In practice, the relative importance of particular software characteristics typically depends on

The degree of software’s ease of use.

There are 2 approaches to software quality: defect management approach and quality attributes approach

The size of a software module will not exceed 30 statements This is what SQ dimension

deviation from expected behavior is defined as

•The ability of software to service multiple requests to the same resources at the same time.

"The failure frequency of a heart-monitoring unit is required to be less than one in 20 years."This is what SQ dimension

Quality models are in the eye of the beholder

What Quality model is this

A human action that produces an incorrect result is the definition of

Metrics for managing and counting defects are such as

The ability of software to perform a function under stated conditions for stated period of time without any error

What SQ model is this

Definition of software quality varies and is debatable

Mc Call model is divided to
