NASA-HDBK-0008, NASA TECHNICAL HANDBOOK: NASA PRODUCT DATA AND LIFE-CYCLE MANAGEMENT (PDLM) HANDBOOK (17-DEC-2012) [S/S BY NASA-HDBK-1004]., This Handbook is published by the National Aeronautics and Space Administration (NASA) as a guidance document to provide engineering information; lessons learned; possible options to address technical issues; classification of similar items, materials, or processes; interpretative direction and techniques; and any other type of guidance information that may help the Government or its contractors in the design, construction, selection, management, support, or operation of systems, products, processes, or services. This Handbook is approved for use by NASA Headquarters and NASA Centers, including Component Facilities and Technical and Service Support Centers. It provides information on product data and life-cycle management (PDLM) and general guidance to adapt the methods needed to implement the requirements in NPR 7120.9, NASA Product Data and Life-Cycle Management (PDLM) for Flight Programs and Projects. This Handbook also addresses elements to consider when developing the PDLM Plan so that enablers and users of the product are better equipped to recognize and avoid pitfalls that might otherwise be experienced. The purpose of this Handbook is to provide information on product data and life-cycle management (PDLM) and general guidance to adapt the methods needed to implement the requirements in NPR 7120.9, NASA Product Data and Life-Cycle Management (PDLM) for Flight Programs and Projects. This Handbook also addresses elements to consider when developing the PDLM Plan (refer to the template in NPR 7120.9, Appendix D) so that enablers and users of the product are better equipped to recognize lessons learned and avoid pitfalls that might otherwise be experienced. The creation, management, and usage of product-related data across a cradle-to-grave life cycle are daily events at NASA. The integration and sharing of electronic product data among Centers, across programs/projects, and with primes and subcontractors have become mission critical. Multi-disciplinary teams (such as systems engineering, product engineering, manufacturing, purchasing, etc.), as well as remote participants (e.g., local or globally disbursed suppliers, subcontractors, etc.), need quick access to (1) the product data on which they are working, and (2) the associated information that better defines product performance, functionality, form, and fit. The amount, type, and fidelity of the data generated and requiring storage increase over the program/project life cycle. The scale and complexity of the storage and retrieval system have to respond to meet the challenges as shown in figure 1, Data over the Program/Project Life Cycle (Sample Only�Not All Inclusive). The linkage between first managing product data at the Center (or authoring stage) during the key activities of design engineering and manufacturing before extending its communication and sharing across the longer life cycle has led to the adoption of the phrase �product data and life-cycle management,� or PDLM, as shorthand for the more cumbersome product data management/product life-cycle management (PDM/PLM) label. (Definitions of PDM and PLM in Section 3.2 explain these terms individually.) PDLM includes configuration management (CM), requirements management, risk management, and other artifacts developed within the product life cycle; therefore interoperability from beginning of life to end of life is a staple and a requirement of PDLM. Product data management (PDM) provides key capabilities that underlie product life-cycle management (PLM) and is widely considered a precursor requirement to effective PDLM. PDLM does not negate product data management. A process for management of technical data is required by NPR 7123.1, NASA Systems Engineering Processes and Requirements, for ensuring that the data required are captured and stored, data integrity is maintained, and data are disseminated as required. PDLM augments PDM and addresses the acquisition and storage of all program/project data�not just technical data used in the life cycle of a system.
