  • Participate in the development of system engineering documentation, such as System Engineering Plans, Initial Capabilities Documents, Requirements Specifications, and Interface Control Documents.
  • Participate in interface definition, design and changes to the configuration between affected groups and individuals through the life cycle.
  • Allocate real-time process budgets and error budges to systems and subsystem component.
  • Derive from the system requirements an understanding of stakeholder needs, functions that may be logically inferred and implied and essential to system effectiveness.
  • Derive lower-level requirements from higher-level allocated requirements that describe in detail the functions that a system component must fulfill, and ensure these requirements are compete, correct, unique, unambiguous, realizable and verifiable.

  • Capture all interface designs in a common interface control format, and store interface data in a commonly accessible repository.
  • Prepare time-line analysis diagrams illustrating the flow of time-dependent functions.
  • Establish a process to formally and proactively control and manage changes to requirements, consider impacts prior to commitment to change, gain stakeholder buy-in, eliminate ambiguity, ensure traceability to source requirements, and track and settle open actions.
  • Assess each risk to the program and determine the probability of occurrence and quantified consequence of failure in accordance with an approved risk management plan.
  • Manage and ensure the technical integrity of system baseline over time, continually updating it as various changes are imposed on the system during the lifecycle from development through deployment and operations & maintenance.
  • In conjunction with system stakeholders, plan the verification efforts of new and unproven designs early in the development life cycle to ensure compliance with established requirements.
