How to develop usable groupware
TOUCHE (Task-Oriented and User-Centered process model for developing interfaces for Human-Computer-Human Environments) is a process model for software development created to develop groupware. The creation of TOUCHE is part of a research project carried out at three Spanish universities. The aim of the project is to create a complete process model for the development of usable groupware. This thesis is part of this project and aims to further advance the TOUCHE process model so that it fulfills its aim on developing for usability. The thesis is based on research from the HCI (Human-Computer Interaction) and CSCW (Computer-Supported Cooperative Work) fields. In the thesis a new version of TOUCHE is created which has a strong focus on developing for usability.This is done by selecting four principles from the HCI field, incorporating what is considered to be most important when developing for usability. The principles are a strong focus on, and the involvement of users throughout the whole process, an iterative process, multidisciplinary design, and aim for groupware usability. TOUCHE is analyzed from these principles and missing elements are identified. The difficulties of integrating these elements into TOUCHE are discussed and finally elements are chosen to be integrated into TOUCHE. These elements include a usability guide, evaluation cycles, prototyping, pre-documentation and a multidisciplinary team.
