A Systematic Approach to Training for Ground Segment using Tasks and Scenarios: Application to PICARD satellite

摘要

Usability has been identified as one of the most critical and most difficult nonfunctional requirement for software systems as reported in ~(18). Without adequate account for user needs, user requirements and lack of input overall cost of software development might exceed 100% as demonstrated by a detailed study over 8000 project in 382 companies. However, beyond the classical 3 factors of usability (as defined in ~(12)) namely efficiency, effectiveness and satisfaction, their integration within the development process of software systems remains a research question not answered by standards or regulation authorities. This paper presents such a development process and its application to the development of large scale interactive systems such as satellite ground segments. It integrates critical characteristics such as iteration, formal description techniques, operators tasks description, prototyping and training design to support in a systematic way the fundamental principles of User Centered Design (UCD).
