The SyRS specifies human system integration requirements, referencing applicable documents: constraints on allocating functions to personnel, communications and personnel-equipment interactions, and requirements for areas, stations or equipment needing concentrated human-engineering attention because human error there would be particularly serious (9.5.9.1); quantitative maintainability requirements for the planned maintenance and support environment, such as mean and maximum downtime, reaction, turnaround and repair times, mean time between maintenance actions, staff-hours per action, readiness rate, maintenance complexity, maintenance cost indices and accessibility of components and parts (9.5.9.2); quantitative reliability requirements with the conditions under which they apply, optionally with an apportionment model allocating reliability to functions (9.5.9.3); and how further quality requirements, compatibility and portability for instance, will be met (9.5.9.4).
