The ADM provides a standard, consistent way of developing and maintaining information systems. It provides uniform terminology and expectations for all project participants. This consistency reduces the learning curve when bringing new people into an on-going project. It also serves as a roadmap for both experienced and inexperienced staff.
The ADM simplifies the development process by re-utilizing clearly defined products and tasks. The sequencing of those tasks and the completeness of those deliverables has been previously proven, thereby ensuring clarity and certainty to the process. The ADM's proven experience ensures that there are no holes to be overlooked or tasks to be duplicated.
Although the ADM provides structure, it also provides criteria for tailoring alternatives to the standard approaches. The ADM 's framework allows UCD to adopt a variety of techniques and tools for carrying out the defined tasks. It also allows UCD to change techniques and/or tools as new products come onto the market without changing the ADM.
The ADM provides a comfort zone for information users. It defines expectations both in terms of what each step will be as well as the role they will have in that step.
