©2001 Southern Illinois University, Edwardsville All rights reserved. Design of the System comes from the Customer Data BUT Design is NOT explicit in the data, it requires a creative leap

©2001 Southern Illinois University, Edwardsville All rights reserved. Data guides, constrains, and suggests directions See a fact about work See why that fact matters Recognize opportunities and implications of applying technology Turn into concrete design ideas Example: “The Electronic Napkin”

Don’t Just Automate Re-Engineer The design team is in a unique position to re-design the work practice Consolidated models provide an overall picture of the current work practices Redefining roles, lines of communication, physical layouts, sequence of activities, and useful artifacts.

Consolidated Flow Model Look for Role Switching Reduce context switch overhead Reduce redundant data entry Support interface consistency across roles Consider role separation Automate roles Look for Role Sharing Tailor data and interface to user Look for Communication Problems between Roles Support lines of communication

©2001 Southern Illinois University, Edwardsville All rights reserved. Consolidated Physical Model The physical model shows constraints imposed by the environment and the structure people create within the constraints to get their work done. Look for Communication Problems Account for work being spread over various locations Improve the flow of artifacts

Consolidated Sequence Model Reveals structure of the work Intents, triggers, activities, strategies What is the primary intent, and is it worth doing? If it is worth doing, can the sequences and triggers be redesigned? Eliminate steps Automate steps Eliminate breakdowns Provide appropriate triggers

Consolidated Artifact Model Reveals structure and intent of artifacts Information content, organization, usage Look for ways to support intent Support intent more directly Support intents indicated by informal usage Look for Information Content Provide data automatically Support Communication between roles Look for Structure Maintain the distinctions that matter to the user (implies strategy)

Creative thinking requires an attitude that allows you to search for ideas and manipulate your knowledge and experience Use crazy, foolish, or impractical ideas as stepping stones to practical new ideas Break the rules occasionally Open yourself up to new possibilities and change.
