From the Publisher: A Small Matter of Programming asks why it has been so difficult for end users to command programming power and explores the problems of end-user-driven application development that must be solved to afford end users greater computational power. Drawing on empirical research on existing end user systems, the book analyzes cognitive, social, and technical issues of end user programming. In particular, it examines the importance of task-specific programming languages, visual application frameworks, and collaborative work practices for end user computing with the goal of helping the designers and programmers understand and better satisfy the needs of end users who want the capability to create, customize, and extend their applications software. The ideas in the book are based on the author's research on two successful end user programming systems - spreadsheets and CAD systems - as well as other empirical research. Nardi concentrates on broad issues in end user programming, especially end users' strengths and problems, introducing tools and techniques as they are related to higher-level user issues.
