Usability engineering models
Coordinate design of total interface
Apply guidelines and heuristic analysis
Collect feedback from field use
Requirement analysis (User profile, task analysis, platform capabilities/constraints, general design principles, usability goals)
Design/Testing/Development (Work re-engineering, CM design, CM mockups, iterative evaluation, screen design standards, prototyping, iterative evaluation, detailed UI design, iterative evaluation)
Installation (user feedback)
The active involvement of users, a clear understanding of user and task requirement
An appropriate allocation of function between users and technology
The iteration of design solutions. Multi-disciplinary design
Use existing knowledge to develop design solutions. Understand and specify the context of use. Specify the user and organizational requirements. Use existing knowledge to develop design proposals. Make the design solution more concrete using simulations. Alter the design in response to the user feedback and iterate until objectives are met. Manage the iteration of design solutions. Provide design feedback. Assess whether objectives have been achieved
