Ahmed Seffah, Jan Gulliksen, Michel C. Desmarais's Human-Centered Software Engineering - Integrating Usability PDF

By Ahmed Seffah, Jan Gulliksen, Michel C. Desmarais

The fields of HCI and software program Engineering have developed virtually independently of one another till the decade, while it grew to become obvious that an built-in and mixed standpoint would receive advantages the improvement of interactive software program purposes. The chapters during this e-book are written via well known researchers who deliver to gentle the foremost integration matters and demanding situations, and supply numerous recommendations to bridging the HCI and SE hole, together with: * Extending software program engineering artifacts for UI specification, reminiscent of annotating use circumstances with job descriptions, * bettering object-oriented software program engineering notations and types * attainable extensions of HCI tools for requisites amassing via box observations and interviews, deriving a conceptual layout version from situation, job versions and use instances and utilizing personae so as to comprehend and version end-users, * New methodologies for interactive structures layout, in addition to methods complementing latest methodologies.

Sample text

All chapters were peer reviewed by at least two reviewers. , 2003b, with permission from Taylor & Francis Abstract The concept of user-centered systems design (UCSD) has no agreed upon definition. Consequently, there is a great variety in the ways it is applied, which may lead to poor quality and poor usability in the resulting systems, as well as misconceptions about the effectiveness of UCSD. The purpose of this chapter is to propose a definition of UCSD. We have identified 12 key principles for the adoption of a user-centered development process, principles that are based on existing theory, as well as research in and experiences from a large number of software development projects.

Representing design artefacts including prototypes using different formalisms that convey the same information about an object but in different forms and terms which are more suitable to developers or usability experts 7. Conveying UCD attitudes, not just tools and methods, to support UCD activities. UCD must be escalated to management level by means of, for instance, business cases. One way is to create a demand for usability guarantees on the consumer/user side. 4 WHY HUMAN CENTERED SOFTWARE ENGINEERING?

Poor understanding of the design documentation. The design was documented in UML and the users were invited to evaluate it. The users had severe difficulties predicting their future use situation based on the UML notation. One of the users said that after having worked with use case modeling, the collaborative prototyping was like ‘coming out of a long dark tunnel’. The design representation principle emphasizes the importance of using representations that are easy to understand for all the stakeholders, in particular as regards the future work/use situation.
