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

Consolidation Process of Induction Individuals Whole User Population ü From facts we learn about individuals, we need to draw conclusions about the general population • Deduction vs. Induction ü What do the individuals say about common work structures, strategies, intent, issues, and problems.

The Affinity Diagram ü Organizes individual notes into a hierarchy of common issues ü IDEO Method Card ü 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 Track Class Assignments To Do Lists U 1 Entered class assignments into PDA U 2 Looked at calendar after each task to decide what to do next U 3 Wrote class assignments on pocket calendar U 3 Made a daily to do list every morning U 2 Wrote class assignments on hand transferred to calendar at end of day Printed a weekly to do list from PDA U 1

Affinity Diagram ü Built bottom-up ü Reveals scope of issues ü Group session drives consensus about the meaning of the data ü Use post-it’s

The Design War Room ü Walking the Wall ü Immersing yourself in the data Beyer & Holtzblat (1998), Contextual Design, Morgan Kaufmann, Page: 204

Consolidating Flow Models ü Pengungkapan pola komunikasi ü Terfokus pada aplikasi dengan mengenali jalur komunikasi untuk mendukungnya ü How-To • Dari alur model individu untuk mengenali peran § Mengumpulkan tanggungjawab organisasi untuk menyelesaikan tujuan • Nama peran dan listing penanggungjawab • Menggambar jalur komunikasi antar peran

Consolidating Sequence Models ü Pengungkapan activitas, tujuan, and strategi ü How-To • Indentifikasi aktifitas dan pembangkit triggers • Menuliskan langkah sebuah abstrak yang merupakan pusat dari yang dikerjakan • Membangkitan aktifitas sequence dan menuliskan langkah sebuah abstrak 175 • Kembali ke model konsolidasi sequences dan listing tujuan dari setiap langkah atau sequences 174 Beyer & Holtzblat (1998), Contextual Design, Morgan Kaufmann, Pages: 173, 174

A Consolidated Sequence Model General Activity Label Goal of Activities Abstract Step Beyer & Holtzblat (1998), Contextual Design, Morgan Kaufmann, Page: 177

Consolidating the Artifact Model ü Mengungkapkan tema organisasi dan konsep yang menggunakan pola kerja mereka ü How-To • kelompok artifacts dari tipe yang sama • Identifikasi bagian / parts • menggambar structure, penggunaan dan , tujuan • Mencatat variasi temuan / perbedaan

A Consolidated Artifact Model Common Structure Common Intent but variation of structure and usage Beyer & Holtzblat (1998), Contextual Design, Morgan Kaufmann, Page: 183
