What is product quality? Quality, simplistically, means that a product shouldmeet itsspecification

The hurdles for maintaining quality Tension between customer quality requirements (efficiency,

reliability, ...) and developer quality requirements(maintainability, reusability, ...)

Some quality requirements are difficult to specify in anunambiguous way

Software specifications are usually incomplete and ofteninconsistent

The quality compromise

Quality attributes are frequently conflicting and increase

development costs.


11/48

Product quality attributes

Attributes of good software (beyond delivering the requiredfunctionality):

Efficiency

Usability (ease of use)

Dependability (reliability, availability, security, safety,)

Maintainability (ease of maintenance)

Quality assurance

Quality Assurance services are provided on-site,offshore or a combination of both, based oncustomers requirements.

Integrated Quality Assurance solutions includes TestStrategy, Test Automation and Test Execution.

The following is a short list of quality assuranceprinciples:Test and QA activities start early in thesoftware development life cycle:

Quality is built into the solution: Do it right the firsttime.

Each step or phase is validated before moving aheadto the next step or phase.

Repeatable processes are established and used by alllike projects.

Processes are continuously reviewed and improved.
