User Centered Design For the Expeditionary Warfare Decision Support System (EDSS) UCD Workshop David Jones APL-University of Washington July 30, 2002
UCD ideas from IBM Do they apply to Navy problems?
What is UCD? "An approach to designing ease of use into the total user experience with products and systems. It involves two fundamental elements - multidisciplinary teamwork and a set of specialized methods of acquiring user input and converting it into design." Vredenburg, K., Isensee, S., and Righi, C. (2001). User-Centered Design: An Integrated Approach (Software quality institute series). Prentice Hall

What UCD Is
UCD for DOD? Do military users expect ease of use? Is user acceptance important? Do DoD developers get user input prior to the design? Should developers/sponsors be concerned about competitiveness?
The Six UCD Principles applied to EDSS What are the main objectives of EDSS? Who are the real users & what do they need to do? Can we define the total experience for EDSS? How can the EDSS design be evaluated? What will compete with EDSS? How can feedback be gathered from fleet users? UCD for EDSS

Three main user groups Decision makers >> O5 to Flag Planners >> Typically officers O2-O4 Supporters >> Typically enlisted E5-E6 Need to know Education level Tactical experience Computer knowledge System requirements EDSS Users
Task Analysis The Analysis of User Tasks should drive the design and evaluation of the HCI Requirements and User Performance Specifications Functional Description Task Description Teaming Environment Decision Making & Cognitive Task Analysis Information Requirements Analysis
Task Description Major Goal: Landing Control Plan Sub Goal: Regulate ship movement Sub Goal: Regulate assault craft Sub Goal: Establish areas for supporting forces Sub-element: Create 4W Grid
Detailed Task Description Task: Building 4W Grid GoalProduce a 4W grid for STOM Plan Product4W Grid with Ships Assigned Performance requirement Produce grid in XX minutes Grid meets Operational requirements (e.g., Commanders intentions, schedule, etc) Information Requirements Ship information: Names, Types, Current disposition, Loadout Area information: Environmental (tides, winds) Landing priority table Assault Schedule: wave numbers, timing, beaches, units, serials Gunfire support schedule ATO

Interface Competition Most users have high expectations from digital technology Today’s users are MS Windows and MS Office savvy Increasing expectation of browser-like operations Function Competition Are there other programs out there that can do nearly the same job but are easier to use ? What Competes w/ EDSS ?
