TAILIEUCHUNG - Lecture Object-oriented software engineering: Chapter 7 - Timothy Lethbridge, Robert Laganiere

Chapter 7 - Focusing on users and their tasks. In this chapter you will learn about the following: Characteristics of users that every software engineer should understand; various ways of working with users to ensure that a software system has both the required functionality and the required usability; some basic principles for the design of simple graphical user interfaces (GUIs), involving windows, menus, icons and pop-up dialogs; how to evaluate user interfaces; how to implement basic GUIs in Java. | Object-Oriented Software Engineering Practical Software Development using UML and Java Chapter 7: Focusing on Users and Their Tasks User Centred Design Software development should focus on the needs of users Understand your users Design software based on an understanding of the users’ tasks Ensure users are involved in decision making processes Design the user interface following guidelines for good usability Have users work with and give their feedback about prototypes, on-line help and draft user manuals © Lethbridge/Laganière 2001 The importance of focusing on users Reduced training and support costs Reduced time to learn the system Greater efficiency of use Reduced costs by only developing features that are needed Reduced costs associated with changing the system later Better prioritizing of work for iterative development Greater attractiveness of the system, so users will be more willing to buy and use it © Lethbridge/Laganière 2001 Characteristics of Users .
