Software Development in an ISO 9000 company

ISO 9001:2008 standard defines requirements for a process-oriented Quality Management System. This means that desired results are achieved more efficiently when the related resources and activities, together with encompassing customer needs and satisfaction, are managed as a process. Quality Management System is specified in a Quality Manual document featuring a three-tier structure, which consists of Quality Processes (including Quality Policies), Quality Procedures and Work Instructions.
The problem is that Work Instructions are sometimes too bureaucratic. A good example of that approach is Tricker’s book on ISO 9000. According to it, a Work Instruction takes about 16 pages. Half of them contains purely administrative data (document data sheet, distribution list, amendments, list of annexes etc.). That makes the whole Quality Management System documentation superfluously thick.
Another drawback of Tricker’s approach is form-orientation: Work Instructions focus on how to fill-in the forms used by the Quality Procedures. What we propose is to make Work Instructions shorter (some elements can be omitted, some, e.g. terminology, can be put together and placed in one section). Moreover, Work Instructions should describe practices specific for a given methodology of
software development.
In our opinion, quality organization needs two things: general Quality Management System operating on a high abstraction level and a Thesaurus (knowledge database), which should materialize company’s knowledge. In the thesaurus templates of e.g. Quality Plans, historical data concerning past projects etc can be deposited. This information will be indispensable during planning and improving software processes.
The clauses of ISO 9001:2008 can be split into two parts. One part describes the general Quality Management System (chapters 4, 5, and 6) while the other part specifies requirements for a methodology to be adopted by an ISO-9000 company (chapters 7 and 8 of ISO 9001:2008). In the remaining part of the paper we will focus on requirements imposed by chapters 7 and 8 of the ISO 9001:2008.
