Agenda

Agenda

  • Overview of the V6 Presentation Layer Design Process

  • Review V6 UPE Enhance HCI Candidates


Background twcs upgrades

Tomahawk Weapon Control System Upgrades

Background - Twcs Upgrades

  • Advantages

    • Continuous influx of new functionality

    • Correct system defects

    • Improves conduct of system tasking

    • Upgrade User Interface

      • User input

      • Refine individual window design

  • Problem:

    • User Interface issues - Non- holistic approach to entire presentation layer

      • Duplicate info across several windows

      • Non-intuitive task flow

      • Unnecessary actions (i.e., button clicks) to accomplish a task


Ttwcs v6 user interface improvements

TTWCS v6 - User Interface Improvements

  • TTWCS v6 User Centered Design: Improve TTWCS v6 User Interface

    • Uses a holistic / Top Down approach to the User Interface Design

      • Focus on required Tasking & System Data Requirements

    • Design Intent:

      • Increase combat effectiveness

      • Provide a high level of situational awareness

      • Make TTWCS easier to learn

      • Support reduced manning initiatives

  • Task centered design of TTWCS v6 Presentation Layer

    • Focus presentation layer on operator and supervisor interaction with the system versus software architecture

  • Enabled through a Task Analysis


Task analysis definitions

Task Analysis Definitions

  • Purpose of Task Analysis

    • Overall vision for TTWCS v6 is to increase Land Attack Warfighter effectiveness without increasing workload on the operator.

    • While increasing effectiveness, it is desired to maintain a high level of situational awareness and safety.

    • These goals can be enabled via task-centered design, which begins with conducting a Task Analysis.

  • Why Task Analysis for v6?

    • Task centered design streamlines user workflow, minimizing non-necessary or repetitive actions

    • Saving time / promote situational awareness performing complex tasks under stringent time constraints in a stressful environment.

    • Task centered design is unachievable without understanding user tasks.

    • At a minimum, most critical tasks must be analyzed to create a baseline of Task Analysis for follow-on versions of TTWCS.

    • Task Analysis also supports training design.

General assumptions

General Assumptions

  • Schedule and budget prohibit analyzing all TTWCS Tasks for v6

    • Identify high priority Tasks

      • Mission and Safety Criticality, Frequency, Mental workload, etc

    • Establish baseline for future versions

  • Task Analysis and Usability Testing supports enhancing HCI

    • Specifically identify flow within tasks and Information Requirements

  • HCI will not be enhanced and moved into the "Presentation Layer" if the associated UPE Enhance HCI candidate is not funded

    • Any HCI that is not funded in this way would be only improved from legacy HCI as needed to account for other functional candidates

    • Assumes UPE09 is funded, requiring no additional modifications to “Business Logic” CSCIs

      • UPE09 will address removal of HCI from business logic CSCIs

    • New/modified windows may require additional data from business logic CSCIs

      • Anticipate data requirement additions will be small

  • New functionality uncovered during Task Analysis requires a CR

  • HCI Improvements may include making windows and navigation more intuitive, reduce button clicks, improve “drill-down” features, etc.
