Human Factors Engineering Program Rating Sheet No/Strongly Disagree 0 Disagree 1 Agree 2 Strongly Agree 3 Score Question Human Interface Design and Development Company and facility-specific human factors engineering design guidelines have been developed and are routinely used for design and development of humanequipment interfaces and for evaluation of vendor-supplied products. A systematic process for tracking usability and ergonomics issues and their solutions exists; all appropriate personnel have been trained in its use, and the process is routinely used for systems under development. A systematic process for tracking development documents such as use cases, class diagrams, activity diagrams, and user-interface specifications exists; all systems development personnel have been trained in its use, and the process is routinely used in systems development. There are very few changes to the design of a new system after its implementation. A systematic review process is in place to continuously evaluate and improve human-interface design, and all personnel have received familiarization training to identify and report interface-design problems that could lead to human error. Usability Of New/Modified Designs An operator who has never seen the system can learn it sufficiently well to accomplish basic tasks (ease of learning). Once an operator has learned to use the system, the operator can accomplish tasks quickly (efficiency of use). Once an operator uses the system, the operator can remember enough to use it more effectively next time and does not have to start over again learning everything every time (memorability). Operators are less likely to make errors while using the new system. Errors that are possible are not severe and operators can easily recover from them (error frequency and severity). Operators are satisfied with the new system. Operators like using the new system (subjective satisfaction). (0 to 3)

Score Question (0 to 3) Operators find that the new system is intuitive to use. The user interface stands alone and is easy to use. The operators use external support systems – training, system support procedures, etc. – less frequently. (ease of use). HFE Techniques, Tools, Methodology System development teams use an iterative design process of analysis, design (with prototyping), evaluation, and implementation. A thorough front-end analysis is used to address the following issues: tasks performed, environment in which task is performed, tools users have, communication between users, frequency of task performance, time constraints on the tasks, and error types and frequencies. A design phase is conducted that translates the knowledge about users, their tasks, and the environments into successive prototype interface designs. The design team applies human factors engineering principles to the design of prototypes. The prototypes are evaluated to elicit usability and preference data from potential end users. Usability testing is conducted at several stages of the interface development. Usability testing documents any difficulties, errors, hesitations, first impressions, opinions, and recommendations from operators. It addresses issues related to: performance problems, task relevance, errors, time, and user satisfaction. The feedback from the evaluations is used to revise the prototype design. When a system is implemented, acceptance testing is conducted. When a system is implemented, training/installation programs are developed. Total Scoring: 51 - 63……………Well designed and managed HFE program. Continue monitoring and enhancement. 33 - 50……………Adequate HFE program. Some weaknesses evident in design and/or practice. 20 - 32……………Marginal consideration of HFE; likely that human-error inducing designs exist. below 20………….Inadequate attention to HFE; human error risk is unacceptable.
