Conceptual Models: Core to Good Design
Teaches the benefits of designing a conceptual model (CM) of apps before designing the UI, the components of CMs and how to create them, and provides experience designing a CM.
A crucial step in designing a UI for a software application is to design a coherent, task-focused conceptual model. With a CM, designers design better, developers develop better, and users learn and use better. Unfortunately, this step is often skipped in software design, resulting in incoherent, arbitrary, inconsistent, overly-complex applications that impede design, development, learning, understanding, and use. Based on the presenter's (coauthored) book: Conceptual Models: Core to Good Design. It covers:
 What CMs are.
 How they improve software design and development.
 Perils of skipping CMs.
 Object/operations analysis.
 Examples of CMs.
 A hands-on exercise designing a CM.

The course presentation consists of lecture, Q&A, and audience exercises. Most of the second segment consists of hands-on exercises and discussion.

The intended audience is designers and developers of all levels, as well as Q/A engineers, usability testers, and managers.
