Where We Are At Where We Are Going Contextual Inquiry – Ethnographic Techniques to collect raw data Prototype – Application with sufficient detail for usability testing User Environment Design – System Blueprint and Interface Specification Visioning – Brainstorming solutions Consolidation – Process of Induction to create a sense of the whole user population from the individual users Work Models – Interpretation Sessions to create a shared understanding of the work and user’s mental models of the work You are here

©2001 Southern Illinois University, Edwardsville All rights reserved. Consolidation Process of Induction Whole User PopulationIndividuals From facts we learn about individuals, we need to draw conclusions about the general population Deduction vs. Induction What do the individuals say about common work structures, strategies, intent, issues, and problems.

The Affinity Diagram Organizes individual notes into a hierarchy of common issues IDEO Method Card How-To In a group session each member has their field notes and a pad of post-its One note is put-up and others look for similar notes that seem to go with it Interview notes are placed together if they have an “affinity” – similar issues, intent, problems Notes are given a group name that states the issue which binds them together

Affinity Diagram Example Time Management To Do Lists Track Class Assignments Wrote class assignments on hand and transferred to calendar at end of day U2 Wrote class assignments on pocket calendar U3 Printed a weekly to do list from PDA U1 Made a daily to do list every morning U3 Entered class assignments into PDA U1 Looked at calendar after each task to decide what to do next U2

Consolidating Flow Models Reveals the patterns of communication Focuses the application by recognizing the line of communication it should support How-To From individual flow models identify common roles  Collection of responsibilities organized to accomplish a goal or set of goals Name each role and list responsibilities Draw communication lines between roles

©2001 Southern Illinois University, Edwardsville All rights reserved. Consolidating Sequence Models Reveal common activities, goals, and strategies How-To Identify common activities and match triggers Write an abstract step that states the work done Match sequence activities and write abstract steps Step back through the consolidated sequence model and list the intent of each step or sequence Beyer & Holtzblat (1998), Contextual Design, Morgan Kaufmann, Pages: 173, 174

Consolidating the Artifact Model Reveals common organizing themes and concepts that people use to pattern their work How-To Group artifacts of similar types Identify common parts Draw common structure, usage, and intent Note variations
