Objectives Hierarchy

The Office of Safety and Mission Assurance (OSMA) has introduced a new objectives-based approach to better support NASA’s increasingly complex missions in a changing design environment. By focusing on objectives, OSMA hopes that the new standards will be more flexible, agile and cost-effective, and will allow more ingenuity to achieve objectives. It will serve as a guide to help programs and projects plan how they will meet their objectives, instead of dictating what they must do to via prescriptive requirements. Read the article, "OSMA Introduces New Objectives-Based Strategies," to learn more about objective hierarchies.

NPD 8720.1 NASA Reliability and Maintainability (R&M) Program Policy

This policy states the R&M requirements all programs and projects must meet during all phases of development and operations.

See NPD 8720.1
NASA-STD-8729.1 Planning, Developing and Managing an Effective Reliability and Maintainability (R&M) Program

This standard provides R&M guidance to customers (or purchasers) and suppliers (or contractors) on R&M requirements development, design implementation and evaluation.

Model-Based Mission Assurance

Model-Based Systems Engineering (MBSE) is seeing increased application in the planning and design of NASA’s missions. The Office of Safety and Mission Assurance is calling the corresponding approach to mission assurance Model-Based Mission Assurance (MBMA). In MBSE, a virtual model of the system is created, typically while it is still in the design or planning phase. The model is used as a singular reference source — a single point of truth — for system concept, requirements and design, and verification and validation and associated data. Safety and Mission Assurance (SMA) can leverage that model to perform a variety of assurance analyses earlier in the life cycle reducing the occurrence of costly changes after the system design has become more hardened. By using the MBSE model, SMA personnel will be able to run simulations and tests in real time, instead of having to wade through — in some cases — thousands of pages of documentation. In addition to being more timely, MBMA promises to be more flexible, faster and more cost-effective.

Probabilistic and Statistical Analysis

Probabilistic and Statistical Analyses are used to determine the risk and risk contribution of a wide variety of applications, such as the International Space Station, new launch vehicles and risk at NASA centers. They evaluate technical risk that impact NASA’s objectives and programs to identify acceptability of ventures, activities, new launches and operations.

Physics of Failure

Physics of failure is an engineering-based approach to reliability that uses modeling and simulation to eliminate failures early in the design by addressing root-cause failure mechanisms. The physics-of-failure approach proactively incorporates reliability into the design process by establishing a scientific basis for evaluating new materials, structures and electronics technologies. Physics of failure encourages innovative, cost-effective design through the use of realistic reliability assessment.
