The design goal is to provide reliable techniques for the repeated design of successful and usable interactive systems. It is therefore necessary that we go beyond the exercise of identifying paradigms and examine the process of interactive system design. In the previous chapter we introduced some of the elements of a user-centered design process. Here we expand on that process, placing the design of interactive systems within the established frameworks of software development. | Lecture 18 socio-organizational issues and stakeholder requirements –Part 1 Today’s Topics Introduction to Social Aspects of system What are Requirements? Organizational Issues Capturing Requirements Socio Technical Model Custom Method Open System Task Analysis Introduction The different people affected by the introduction of a system are known as stakeholders and their needs can be both complex and conflicting. Introduction of a new system effect the organizational and work practices in any organization. Several issues can effect the acceptance of new technology. Introduction Requirement engineering mostly focus on functional requirements. what the system must be able to do Mostly less emphasis is given on non-functional human issues such as usability and acceptability. Requirements? Requirements are statements of what the system must do, how it must behave, the properties it must exhibit, the qualities it must possess, and the constraints that the system and its development must satisfy. Requirement Engineering Requirements engineering emphasizes the use of systematic and repeatable techniques that ensure the completeness, consistency, and relevance of the system requirements [Sommerville 1997a]. Requirement Engineering Functional Requirement A functional requirement describes what a software system should do For example, functional requirement would be that a system must send an email whenever a certain condition is met (. an order is placed, a customer signs up, etc). Usability Usability is the measure of a product's potential to accomplish the goals of the user. Acceptance Typical scenarios under which user will use the accepted system. Real world testing of user acceptance or beta testing corresponds to the acceptance of software system. Organization issues There are several organizational issues that effect the acceptance and relevance of information and communication systems. Organizational Issues These mainly includes Cooperation or conflict?
