life cycle directive
  Definition: Directives from beyond the model boundary that initiate or constrain support activities from concept through disposal.

NOTE    These directives include:

  • law and political dictates
  • environmental and safety directives
  • business, organizational and program strategies and policies
  • standardization policy and directives
  • program plans (what, when, where and who)
  • program business goals, objectives, targets and constraints (for example, annual budgets, performance targets, thresholds and skills)
  • information on the organization, portfolio, program, projects and so on related to the product in focus
  • priorities that are from the life cycle owner and affect the feasibility of providing needed support elements
  • decisions arising from consideration of requests to the life cycle operator
  • day to day management instructions that affect support activities.

Business, organizational and program strategies and policies address topics such as:

  • corporate support
  • risk
  • quality
  • procurement
  • contracting
  • configuration management.

Life cycle directives include any exceptional maintenance demands and information from the operational plan, sufficient to define each support opportunity, and to serve as a constraint on "Plan and control support delivery" (A4.1).
