Work Reengineering and Conceptual Design
Work Reengineering
•Minimizing retraining
•Reengineering the work to more effectively support business
goals
•Realizing the power and efficiency that automation makes possible
“Task Allocation”
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.
 Using that, a general
Use Scenario is made
to outline a rough design
for the reengineered
system.
Task Allocation
starts with
theon
creation
of thethe
Essential
Use Cases…

Use Cases

showing
interaction
between the user tasks and system tasks
The Essential Use Case does not contain details but
does layout the expected necessary tasks.
CONCEPT DESIGN
The process of establishing the underlying organization & structure of a UI.
Content Diagrams are “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….
