How to implement Ansi Geia-std-0009 Pdf?
Plan and define reliability objectives
The first step in implementing Ansi Geia-std-0009 Pdf is to plan and define the reliability objectives for the system/product. This involves soliciting, investigating, analyzing, understanding, and agreeing to the user's requirements and product needs. The developer, working with the customer and user, should ensure that the user's requirements and product needs are fully understood and defined, so that a comprehensive design specification and Reliability Program Plan can be generated.
The Reliability Program Plan is a document that describes how the reliability program will be executed throughout the system/product life cycle. It should include the following elements :
The reliability objectives for the system/product, such as reliability targets, metrics, criteria, assumptions, constraints, and risks.
The reliability program activities for each phase of the system/product life cycle, such as planning, analysis, design, verification, production, operation, support, and disposal.
The reliability program resources for each activity, such as personnel, tools, methods, techniques, data sources, standards, guidelines,
procedures, documentation, training, and budget.
The reliability program responsibilities for each activity, such as roles, tasks, deliverables, milestones, reviews, audits, and approvals.
The reliability program coordination for each activity, such as communication, collaboration, integration, and feedback among developers, customers, users, and other stakeholders.
Use reliability and systems engineering processes
The second step in implementing Ansi Geia-std-0009 Pdf is to use well-defined reliability and systems engineering processes to develop, design, and verify that the system/product meets the user's documented reliability requirements and needs. The developer should implement a set of engineering activities (included in this standard as normative activities and informative activities, refer to Section 3 of ) so that the resulting system/product satisfies the customer's documented requirements and needs.
The normative activities are those that are required to be performed by the developer to comply with this standard. They include :
Reliability Requirements Analysis: The process of identifying, defining, allocating, and documenting the reliability requirements for the system/product and its components.
Reliability Design Analysis: The process of designing the system/product and its components to meet the reliability requirements using methods such as reliability modeling, prediction, allocation, apportionment, optimization, trade-off analysis, and design for reliability (DFR).
Reliability Verification Analysis: The process of verifying that the system/product and its components meet the reliability requirements using methods such as reliability testing, demonstration, evaluation, validation, and assessment.
The informative activities are those that are recommended to be performed by the developer to enhance the reliability program. They include :
Reliability Program Management: The process of planning, organizing, controlling, monitoring, and reporting the reliability program activities and resources.
Reliability Risk Management: The process of identifying, analyzing, mitigating,
the reliability risks for the system/product and its components.
Reliability Data Management: The process of collecting, storing, processing, analyzing, and reporting the reliability data for the system/product and its components.
Reliability Growth Management: The process of improving the reliability of the system/product and its components through iterative testing, analysis, and corrective actions.
Reliability Configuration Management: The process of establishing and maintaining the consistency and traceability of the reliability requirements, designs, verifications, data, and documentation for the system/product and its components.
Verify reliability during production
The third step in implementing Ansi Geia-std-0009 Pdf is to verify that the developer has met the user's reliability requirements and needs prior to fielding. The developer should include activities that assure the customer that the reliability requirements and product needs have been satisfied. The multifunctional team should verify during production that the system/product and its components conform to the design specifications and reliability targets.
Some of the activities that can be performed to verify reliability during production are :
Reliability Qualification Testing: The process of testing the system/product and its components under simulated or actual operational conditions to verify that they meet the reliability requirements.
Reliability Acceptance Testing: The process of testing the system/product and its components under specified conditions to verify that they meet the acceptance criteria.
Reliability Screening Testing: The process of testing the system/product and its components under accelerated or overstressed conditions to detect and eliminate latent defects or failures.
Reliability Auditing: The process of reviewing the reliability program activities, resources, responsibilities, coordination, and documentation to verify that they comply with this standard.
Monitor and assess reliability in the field
The fourth step in implementing Ansi Geia-std-0009 Pdf is to monitor and assess the reliability of the system/product in the field. The multifunctional team is responsible for identifying the data elements to assess the reliability of the system/product in the field and to ensure the data collected are accurate and complete. The team should establish a closed-loop feedback method to flow recommended improvements (corrective actions) for monitoring reliability growth.
Some of the activities that can be performed to monitor and assess reliability in the field are :
Reliability Field Testing: The process of testing the system/product and its components under actual operational conditions to measure and evaluate their reliability performance.
Reliability Field Data Analysis: The process of analyzing the reliability field data using statistical methods and techniques to estimate and predict the reliability parameters and metrics for the system/product and its components.
Reliability Field Feedback: The process of providing feedback on the reliability field performance to the developers, customers, users, and other stakeholders for improvement, correction, or modification purposes.
What are the best practices for Ansi Geia-std-0009 Pdf?
Use a systematic approach
A best practice for Ansi Geia-std-0009 Pdf is to use a systematic approach to engineering or reengineering a system/product, incorporating best practices that have evolved considerably in recent years. The systematic approach of this standard is applicable for completing corrective actions, making refinements, developing derivatives, producing modifications, updating existing products, creating and realizing new systems, allowing for the safe and cost-effective disposal (retirement) of a system/product .
This approach is incrementally applied in an engineering life cycle framework that can be implemented during any one or more phases of an enterprise-based life cycle (for example, during production, operations, support, or disposal). The defined approach has two premises :
The user's requirements and product needs are paramount. The developer shall work closely with the customer and user to ensure that their requirements and needs are fully understood and met.
The developer shall use a set of well-defined engineering activities (normative and informative) to achieve high reliability in systems/products. The developer shall select and perform the appropriate activities for each phase of the system/product life cycle.
Use a multifunctional team
A best practice for Ansi Geia-std-0009 Pdf is to use a multifunctional team to plan and implement the reliability program. A multifunctional team is a group of people with different skills, expertise, and perspectives who work together to achieve a common goal.
