The ISO 13407 "“user-oriented organization of interactive systems"” is a German standard, which describes a prototypischen user oriented software development process. A special development process can be regarded as to it conformal, if its recommendations are fulfilled. The ISO 13407 in June 1999 in its German version as standard one confirmed.

Structure

The standard consists in its structure both of the descriptions of planning user-oriented organization to make use suited and from explanations the development of interactive systems, which on it concentrates, systems. These describe very well readable form an iterative development process in more briefly, clearer and for a standard, with which user and task characteristics determine the development of the software. In addition the standard contains further guidelines and tables for reporting on user-oriented activities.

Development process

The standard represents user-oriented organization as a specializedspreading activity, which covers knowledge over human factors and ergonomic knowledge and techniques. The ISO process consists of four substantial partial activities:

1. Use context understand: The result of this activity is a documented description of the relevant users, their tasks of work and their environment.
2. Requirements specify: During this phase the goal sizes are derived from the already existing documentation on one compromise level. The division of the tasks of system into such, by humans and into such, those of the technology will be accomplished is determined.
3. Solutions produce: This can take place in the sense of a rapidly prototyping or another iterative process. However these prototypes can be still pure paper drafts (Mock ups) or already executable program versions. If there are enterprise-internal organization rules for user interfaces, these should be used.
4. Solutions evaluate: The solution for the fulfilment of the fixed requirements are examined. In addition can serve expert Reviews, Usability tests or questionings or also a mixture from it. The deviations discovered thereby are evaluated then on their relevance and are starting point of the next iteration of the development process.

This procedure is complementary to existing processing concepts of software engineering and supplements these. The user-oriented organization process should according to the standard already in the earliest stage of the project begin and should then repeated be gone through, until those system fulfills the requirements. The meaning and the expenditure for the user-oriented organization measures at the size and kind of the product which can be developed and for smaller projects by individuals one steers.

Criticism

In the procedure of the user cent-talk Design is higher the portion of direct user participation of the development process. Nothing the defiance must measure the requirement of the standard at these forms of partizipativer software development. The standardized procedure does not seem to admit also the straight indispensable creative free space for the software development.
