IT Quality Policy

(Alias: IT quality values)

Action from principle … divides the individual, separating the diabolical in him from the divine.
– Henry David Thoreau

An IT quality policy states the basic beliefs that drive your organisation to deliver quality in software intensive systems. It acts like a company constitution informing people’s actions when there is no specific procedure to guide them, especially in high stress situations. For example a policy statement that says: “we don’t ship untested code” should inform the actions of a project team when a deadline is upon them, they are under pressure to deliver but testing is not complete. Quality policies also identify organisational priorities separating the critical few from the important many. A policy may also summarise measures of success (for example: customer satisfaction).

Communicating your IT quality policy

Who Writes the Quality Policy?

Senior management demonstrates commitment to quality by writing a quality policy and making sure that everyone in the organisation has read it and understands its implications. Note that the existence of a documented quality policy is a mandatory requirement of ISO 90011.

Writing a Quality Policy

Quality policies are formulated from basic quality principles as they apply to an organisation’s business environment. They touch on the following subject areas:

Customer focus
- Understanding current and future customer needs
- Meeting the customer’s requirements
- Striving to exceed the customer’s expectations
Leadership
- Creating an environment where everyone can contribute to quality
Engagement with people
- Making everyone aware of the need to contribute to quality
- Ensuring full engagement in activities that impact quality
Process approach
- Developing a commitment to describing all work in terms of processes
System approach
- Managing the business as a set of interacting processes
Continual improvement
- Encouraging constant refinement of processes to improve quality
Fact based management
- Making decisions based on analysis of process data
Mutually beneficial supplier relationships
- Developing close co-operative relationships with suppliers.
