Even fairly common software errors can cost up to £1000 to correct. Measures you can take to reduce the occurrence of errors may pay for themselves surprisingly quickly.
Such measures might include:
Quality cannot be "added in" by the quality control process. Good quality products are made that way from the start, not improved by testing at the end of a project
Some individuals consistently produce work of high quality (and others consistently poor quality), so choose a good team
Make everyone in the organisation responsible for the quality of the final product(s). This is the basis of "Total quality management" or TQM Encourage a quality culture in the organisation
Companies have to work hard to earn a reputation for high quality projects (bad reputations come more easily)
A poor quality project can put a supplier in breach of contract, and the customer may stop all payments to them (even for software and services unrelated to the project in question)
A customer is unlikely to sign a contract with a supplier that has run unsuccessful projects in the past
Can a company limit their liability for poor software?
