3-10 Research for Service Analysis

Specifying Human Factors Activities. A large project should include a focus on workflow, usability, procedures, equipment, workload/staffing, human error and operational suitability. This can include both material (e.g., equipment) and non-material (e.g., procedures) needs, shortfalls and concepts and inputs needed by stages in the stages of the Acquisition Management System (AMS) process. Activities also should include consideration of the requirements for the ONA and ISR Checklist. Keeping in mind the need to tailor the effort to reflect the nature and magnitude of the project (HF-STD-004A), possible activities include:

• Ethnographic studies (on site observation/interviews of prospective users)
• Input from operational users and other stakeholders using questionnaires, focus groups, structured interviews and use case reviews
• Task, functional and user analyses, including development of use cases, scenarios and Critical Task Analysis Reports, considering the broader hardware, software and distributed work context
• HF input to a preliminary CONOPS, with a separate CONOPS for the different user groups (including operations and maintenance) as needed
• Specification of the HF aspects of the ONA and associated set of preliminary functional requirements
• Design of storyboards, user interface mockups and functional prototypes
• Completion of formative evaluations of storyboards, user interface mockups and prototypes, including evaluations of alternative designs and design features using heuristic analyses, cognitive walkthroughs, usability studies and/or Human-In-The Loop studies (HITLs) to evaluate usefulness and usability
