Five Views of Software Quality

Manufacturing view

This view has its genesis in the manufacturing industry – auto and electronics.

Key idea: Does a product satisfy the requirements?

Any deviation from the requirements is seen as reducing the quality of the product.

The concept of process plays a key role.

Products are manufactured “right the first time” so that the cost is reduced

Development cost

Maintenance cost

Conformance to requirements leads to uniformity in products.

Some argue that such uniformity does not guarantee quality.

Product quality can be incrementally improved by improving the process.

The CMM and ISO 9001 models are based on the manufacturing view.
