SYNTHESIS LECTURES ON HUMAN-CENTERED INFORMATIC...

People make use of software applications in their activities  applying them as tools in
carrying out tasks. That this use should be good for people--easy  effective  efficient  and
enjoyable--is a principal goal of design. In this book  we present the notion of Conceptual
Models  and argue that Conceptual Models are core to achieving good design. From years of
helping companies create software applications  we have come to believe that building
applications without Conceptual Models is just asking for designs that will be confusing and
difficult to learn  remember  and use. We show how Conceptual Models are the central link
between the elements involved in application use: people's tasks (task domains)  the use of
tools to perform the tasks  the conceptual structure of those tools  the presentation of the
conceptual model (i.e.  the user interface)  the language used to describe it  its
implementation  and the learning that people must do to use the application. We further show
that putting a Conceptual Model at the center of the design and development process can pay
rich dividends: designs that are simpler and mesh better with users' tasks  avoidance of
unnecessary features  easier documentation  faster development  improved customer uptake  and
decreased need for training and customer support. Table of Contents: Using Tools   Start with
