  1. Contextual Design for IBIS-PH 25th eHealth=Utah Brown Bag March 24, 2010 Kathryn Marti, Director, Office of Public Health Assessment

  2. Rocky Mountain Center of Excellence in Public Health Informatics (CoE II) Part of Project 1: “develop an EpinomeApp for the IBIS-PH to visualize and correlate community indicators for health promotion” http://rockymountaincoe.org/

  3. Contextual Design • User-centered • Customer-centered • Set of techniques • Can connect to other methods – • e.g. ‘Rational Unified Process’ • Leads to development of ‘Use Cases’ • Precedes usability testing in lab

  4. STEPS • Define project scope • Decide number & type of interviews • Set up & conduct interviews • Run interpretive sessions • Affinity building & consolidating sequence models • Visioning • Storyboarding • Testing

  5. Project Focus “Improving Public Health Assessment potential of IBIS-PH by incorporating some features of Epinome”

  6. Number & Type of Interviews • Number • Generally 6-8 interviews • Type of interviews • What work or activity you expect to support • Context • State health department • Local health department • Media • Researchers & students • Government • Community health

  7. Contextual Inquiry • Field Interviews conducted with users in their workspaces. • Observe and inquire into the structure of the users own work practice. • Capture the real business practice and daily activities the application should support. • Post interview team interpretation sessions to build models of the work practice.

  8. Contextual Interviews: Key Concepts • Context. Understand the context by collecting data from users doing real work at their site. • Partnership. Learn like an apprentice what is going into the work. • Interpretation. Create a shared understanding of the work to uncover meaning behind user action. • Focus. Steer conversation by probing from a clearly defined project focus.

  9. Contextual Interviews: Phases • Project Introduction- IBIS improvement. • Deal with opinions about IBIS. • Transition to observation. • Observe and discuss – maintain focus while taking retrospective accounts and using artifacts. • Share design ideas with the user stimulated by events. • Wrap-up – check high-level understanding, give IBIS tips.

  10. Recording Contextual Interviews • Audiotape (ask permissions) • Interviewer notes • Retained artifacts • Unreconstructed recall

  11. Work Models Emerging from Contextual Interviews Physical Model - User’s physical environment that affects work. Sequence Model – tasks observed or retrospectively accounted during the interview. Artifact Model – “things” the user creates, references or passes in accomplishing tasks. Flow Model – communication and co-ordination with others required to accomplish tasks. Cultural Model – Influences on the user: constraints, policies, value propositions that must be supported by the application
