NASA GSFC-STD-1000G, GODDARD TECHNICAL STANDARD: RULES FOR THE DESIGN, DEVELOPMENT, VERIFICATION, AND OPERATION OF FLIGHT SYSTEMS (30-JUN-2016) [aka "GOLD RULES"]., The Goddard Open Learning Design (GOLD) Rules specify sound engineering principles and practices, which have evolved in the Goddard community over its long and successful flight history. They are intended to describe foundational principles that �work,� without being overly prescriptive of an implementation �philosophy.� The GOLD Rules are a select list of requirements, which warrant special attention due either to their historical significance, or their new and rapidly evolving nature. The formalization of key requirements helps establish the methodology necessary to consistently and efficiently achieve safety and mission success for all space flight products. The GOLD Rules share valuable experiences, and communicate expectations to developers. Where appropriate, the rules identify typical activities across lifecycle phases with corresponding evaluation criteria. The GOLD Rules also provide a framework for the many responsible Goddard institutions to assess and communicate progress in the project�s execution. The GOLD Rules ensure that GSFC Senior Management will not be surprised by late notification of noncompliance to sound and proven engineering principles that have made GSFC missions consistently successful. Each GOLD Rule specifies requirements in the form of a Rule Statement, along with supporting rationale, and guidance in the form of typical lifecycle phase activities and verifications. The GOLD Rules focus on fundamental principles and practices, and therefore are intended to apply to all space flight projects (and where applicable, associated ground projects) regardless of implementation approach or mission classification (except where explicitly noted). Whenever necessary, rules clarify requirements and expectations consistent with different mission classifications. Although not required, an a priori Mission Exceptions List (MEL) may be proposed at the start of a Program and/or Project, to highlight rules which may not apply to that mission. If a MEL is submitted and approved, waivers will not be required for exceptions covered by the MEL unless changes occur to the underlying basis for exception. For rules that include multiple elements (e.g., �test as you fly�), waivers and exceptions are valid for the specific elements indicated in a MEL or waiver and do not constitute a global approval to waive all elements of that rule. Other exceptions that arise during execution of the mission still require waivers, as appropriate. A MEL approved at the program level for multi project programs will be reviewed at key points in the program lifecycle (e.g. at the release of a new Announcement of Opportunity) to validate its applicability for new Projects within that program. The GOLD Rules is a living document, periodically assessed and updated to improve its clarity of purpose and effectiveness. While the engineering principles and practices are stable, the select set of requirements may evolve based on whether they continue to warrant increased visibility by their inclusion. The intent is to improve the GOLD Rules over time, not to grow it in size, complexity, and coverage so that it becomes more cumbersome and less helpful over time. Requirements temporarily included because of their new and rapidly evolving nature, must be accompanied by transition plan out of GOLD rules and into an appropriate lower level document.
