Create processCreate process

Create.Create. Information is created, most likely by Information is created, most likely by processing the input. Typical approaches to processing the input. Typical approaches to information creation are analysis of the input, information creation are analysis of the input, synthesis of information input, and through synthesis of information input, and through human input and intervention, for example, in human input and intervention, for example, in drafting and 3D modelling. drafting and 3D modelling.

Edit.Edit. Editing involves quality control of the Editing involves quality control of the information, checking it against standards, information, checking it against standards, requirements. The create and the edit steps may requirements. The create and the edit steps may form a loop.form a loop.

Record.Record. Information which is finalised in the Information which is finalised in the create and edit step should be recorded, for create and edit step should be recorded, for example, into a file, printed out ...example, into a file, printed out ...

Distribute.Distribute. Information is distributed to the Information is distributed to the potential users. It can be sent directly to a person potential users. It can be sent directly to a person or placed on the Web, product database, library or placed on the Web, product database, library or company archive. In some cases the record and or company archive. In some cases the record and distribute steps are joined.distribute steps are joined.
