  1. Chapter 8 Work Reengineering and Conceptual Design

  2. Work Reengineering • Minimizing retraining • Reengineering the work to more effectively support business goals • Realizing the power and efficiency that automation makes possible

  3. Creating and Assigning individual actions to the user or the computer • First, the current system • is analyzed. And with it • the Task Scenario is • created. “Task Allocation” • Using that, a general • Use Scenario is made • to outline a rough design • for the reengineered • system.

  4. Task Allocation really starts with the creation of the Essential Use Cases… The Essential Use Case does not contain details but does layout the expected necessary tasks. Essential Use Cases focus on showing the interaction between the user tasks and system tasks

  5. CONCEPT DESIGN The process of establishing the underlying organization & structure of a UI. Content Diagramsare “low-fidelity” prototypes that represent the designer’s perspective on the organization and structure. (later) A Concrete Use Case can be derived from the Essential Use Case. It is practically the same, but contains likely details to focus the cases. The next step in concept design is to objectify the use cases….

  6. Identifying Objects Attributes Actions Task Objects • View • Add • Print • Delete • Save • academic • title • CD-ROM • year • research student • email address

  7. Task Object Properties of Task Object Each Task Object is connected to others to form the prototype Actions available for Task Object Child/Parent Task Objects
