Quality Management

Getting it Right


Quality Management

It is not enough to make sure you get it done on time and under budget – but it has to be of good quality

Quality is a measure of how well your product does what you intend

How closely your product meets the requirements

Cost


Product Quality Attributes

• Reliability - The probability of failure-free system operation over a specified time in a given environment for a given purpose

• Availability - The probability that a system, at a point in time, will be operational and able to deliver the requested services

• Safety - The system’s ability to operate, normally or abnormally, without danger of causing human injury or death and without damage to the system’s environment

• Security – The system’s ability to protect itself from accidental or deliberate external attack


Product Quality Attributes

• Efficiency– Software should not make wasteful use of

system resources (disk and memory space, CPU time, etc.)

• Usability (ease of use)– Software must be usable by the users for

which it was designed

• Dependability (reliability, availability, security, safety,…)

• Maintainability (ease of maintenance)

ISO 9000

• International set of standards for quality management (ISO 9000:2000, ISO 9001:2000, ISO 9004:2000, etc.)

• Applicable to a range of organisations from manufacturing to service industries

• ISO 9004:2000 provides guidance for continual improvement of a quality management system to benefit all parties (employees, owners, suppliers, society in general,…)


ISO 9000 certification

• Quality standards and procedures should be documented in an organisational quality manual

• External body may certify that an organisation’s quality manual conforms to ISO 9000 standards (namely ISO 9001)

• Customers are, increasingly, demanding that suppliers are ISO 9000 certified

The CMM and ISO 9000

• There is a clear correlation between the key processes in the CMM and the quality management processes in ISO 9000

• The CMM is more detailed and prescriptive and includes a more detailed framework for improvement

• Organisations rated as level 2 in the CMM are likely to be ISO 9000 compliant
