Title: Human Systems Integration (HSI) Event Report

Use/Relationship: The HSI Event Report provides evidence that the human‐system interface requirements for the operation, maintenance, and support of the system have been met. This report serves as the principal means of assessing the compatibility of the human performance requirements, personnel selection criteria, training program, and design of the human equipment/software interfaces. This report will be used to determine whether and to what level or standard(s) each trained individual can perform in the specified sequence all assigned systems tasks, to determine whether and to what extent each individual's performance is affected by equipment configuration, the performance of other system personnel, or both; and to assess the impact of the measured human performance on the attainment of task, task group, and mission requirements.

a. This Attachment contains the format and content preparation instructions for a HSI Event Report resulting from the work task delineated in the contract Statement Of Work (SOW).

Requirements:

1. General. The HSI Event Report shall be prepared for each personnel position in the system being developed. All of the operations and maintenance tasks required of the individual assigned to a personnel position shall be referred to as the "task group" of the position.

2. Format. The HSI Event Report format shall be Contractor selected. Unless effective presentation would be degraded, the initially used format arrangement shall be used for all subsequent submissions.

3. Content. The HSI Event Report shall contain the following:

a. Introductory information.

(1) Specific title of event.

(2) Identification of equipment or concept being assessed.

(3) Specific purpose of this event.

(4) Objectives of this event (if appropriate, stated in terms of hypothesis to be assessed).

(5) Date(s), location(s), names(s) of individuals present and supervising the conduct of the event.

(6) For each task group or portion thereof reported, a list of all the discrete tasks and a brief description of‐the operational environment in which they are to be performed when the system is deployed.

b. Description of assessment methods and controls. The following assessment methods and controls shall be described:

(1) Human performance standards. State or reference any human performance standards (e.g., "0.9 probability of operator launching missile within 10 seconds after detecting target") or assumed contribution to error (e.g., "aiming error less than 3 mils") contained in system development documents. If none, so state.

DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.

(2) Environment. Describe the environment at each distinct location of human performance: (Include noise and illumination levels, shock and vibration, air temperature and humidity, and ventilation. Also, state the concentration of, and event participant exposure time to any toxic or hazardous substances, and state whether that exposure was or was not within the applicable safety limits for each substance).

(3) Event participants. Describe event participants. For each participant, where relevant, state age, weight, rank, body dimensions applicable to performance tasks, visual acuity and hearing levels, any known physical disabilities, and educational and work experience.

(4) Individual clothing and equipment Describe individual clothing and equipment (including all clothing and equipment worn, carried or otherwise borne on the body, such as weapon, communications equipment, headgear and protective mask).

(5) Pre‐event training. Describe type and amount (in hours) of system‐specific pre‐event training (differentiating "hands on" practice from other training) given to event participants; and type, content and results of training used. Also, state time intervals between end of training, training assessment, and start of events being reported.

(6) Mockup or equipment. Describe the mockup or equipment on which event is conducted (including material used and type of fabrication, dimensions, and cross‐ reference to blueprints, drawings or sketches).

(7) Deviations. Identify deviation(s) during the event from conditions of expected use (see paragraph 3.a.(6) above); narrative explanation of reason(s) for deviation(s), and presumed effect(s) of such deviation(s) on the validity of generalizations from event data.

c. Data collection and use. The following shall be identified or described, as indicated:

(1) Identification of the quantitative and qualitative measures of both human and system performance.

(2) Description of methods, procedures, and instrumentation used in data collection.

(3) Description of techniques used for data reduction, statistical techniques employed, and confidence levels selected.

d. Results. The following results shall be summarized:

(1) Quantitative human and system performance data.

(2) Qualitative data (including questionnaires, interviews, and checklists).

e. Human performance errors. The following considerations of human performance shall be described:

(1) Each error (narrative description, with photograph(s) if appropriate) and frequency of occurrence.

(2) Consequence (brief statement of the immediate effect of the error on system operation).

(3) Causes (isolation of the immediate cause of each actual performance error and identification of the events, conditions, operator workload, environmental factors, and equipment configurations which may have contributed to it).

(4) Explanation by participants making errors of the reasons for the errors.

(5) Recommended solutions (stated in terms of equipment redesign, alteration of tasks, personnel selection, training, or a combination of these) and rationale.

f. Incompatibilities among human performance and equipment.

(1) Identification. The following incompatibilities encountered during the event shall be identified:

(a) The tasks of one task group that interfered with the performance of tasks of another task group. (Identify both the interfering and affected tasks.) If none, so state.

(b) The human performance that was adversely affected by equipment configuration or characteristics. (Identify the human performance, equipment involved, and controls or displays needed but not present.) If no adverse effects on human performance were encountered, so state.

(2) Recommend solutions. Recommend solutions (stated in terms of equipment redesign, alteration of tasks, personnel selection, and training). Provide rationale.

g. Observed safety hazards. Descriptions of each safety hazard encountered during the event shall include the information below. If none were encountered, so state.

(1) Narrative description, with photograph(s) if appropriate.

(2) Frequency of occurrence.

(3) Severity and consequences.

(4) Recommended action to eliminate or minimize hazard. (State in terms of equipment redesign, alteration of tasks, personnel selection, training, or a combination of these, and provide rationale).

h. Analysis of impact of human performance on attainment of system performance goals. This analysis shall include a:

(1) Statement of (or reference to) system performance goals.

(2) Narrative explanation of reasons why any human performance tasks required by present equipment design are not feasible, or why any standards presently set for specific performance tasks are unattainable. (If all human performance requirements are feasible and any standards set appear to have been met, so state).

(3) Narrative explanation of how measured human performance times and errors in operations and maintenance can affect system reliability and availability.

(4) Narrative explanation of how measured human performance times and error frequencies and magnitudes can affect system effectiveness.

(5) Narrative explanation of how system performance goals would be affected by implementing the solutions recommended in paragraphs, 3e, 3f, and 3g above.

i. Conclusions. Conclusions shall include:

(1) Summary of major findings from event.

(2) Implications of major findings (including anticipated effects on system reliability, availability, and effectiveness.)

j. Recommended changes. List of recommended changes to equipment configuration, human performance tasks, personnel selection and training (in order of decreasing importance) with indication of government or Contractor organization responsible for implementing recommended actions.
