Development of user information products for complex technical systems
Sammanfattning: Interaction with technological systems is an intrinsic part of daily life. The complexity of these man-made systems has reached unprecedented levels, and challenges the organizations that create and utilize them. At the same time they are often used in environments which imply very high requirements on safety, credibility, and reliability. Users of a complex system needs support to access and maintain the utility and services the system-of-interest or product, is to provide. Alongside more traditional support like service and maintenance, customer support also includes comprehensive documentation. Despite tremendous development of documentation for complex products, there is still a problem for users to access and understand the information. Development methods for user information products therefore need to be evolved.The purpose of this study is to explore and describe the development of stakeholder based information products for complex technical systems. The knowledge wanted is a model linking theory to real life applications, i.e. methodologies and tools that can support the development and continuous improvement of stakeholder based information products for complex technical systems. To fulfill the purpose a case study supported by a literature study has been made. The case study focused on a modern combat aircraft, which is considered as a highly complex system with stringent requirements on user information support. A development method for user information products was adapted and then applied and studied during the development of a demonstrator. The result of the study may be described in two parts. The first part is the identification of methodologies and tools for elicitation of requirements and user information development, from the area of cognitive science and joint systems of man-machine, quality technology and formal requirements management. The second part is the validation of the suggested way of working, tested through the development of the demonstrator. Compared to traditional development work the suggested way of working supplies increased stakeholder focus and a more efficient communication between developers and stakeholders, as well as within the development team. It also facilitates and improves requirements management and the possibility to reduce business risks connected to misinterpretations and disagreements over specifications.
