Requirements, models, and prototypes for HCI design

Abstract

Requirements, Models, Prototypes (RMP) is a structured process for HCI design for industrial software development teams. It consists of an organized collection of ten design deliverables, templates for each, and a set of practices. RMP is derived fi-om the authors' ongoing experience and the HCI literature of research and practice. It was devised to aid experienced designers and to help beginners learn. The tutorial is intended for those already familiar with basic HCI design who desire a more systematic approach.

It was devised to help HCI designers be more cost effective and to promote the fit of HCI design work into industrial software development processes. It is a statement of the current routine practice of the authors.The components of RMP are: q q q A specific minimal set of HCI design deliverables (methods) and their known relationships for each of three groups, Requirements, Models, Prototypes (ten deliverables in all).Templates (tools) for each of these deliverables to promote repeatability, reliability, and efficiency as well as to help beginners.A set of five design practices that help designers work comfortably in contemporary software development environments.
