Site problems Data Management (DM) The Data Management Body of Knowledge (DMBOK) definition is: "Data management is the development, execution and supervision of plans, policies, programs and practices that control, protect, deliver and enhance the value of data and information assets." • Data management plays an important role in facilitating other systems engineering processes. DM: • Enables collaboration and life cycle use of acquisition system product data, • Captures and organizes all systems engineering artifacts input to, processed by, or output from systems engineering processes, • Documents traceability among requirements, designs, solutions, decisions, and rationale, • Records engineering decisions, procedures, methods, results, and analyses, • Facilitates technology insertion for affordability improvements during re-procurement and post- production support, • Supports CM, risk management, interface management, requirements management, trade-off analyses, technical assessment, and technical review activities Under the life cycle management approach, the program manager is responsible for the DM for each phase of the system life cycle. The program manager should determine the data needs of the program (including external obligations) and develop a long-term strategy that integrates data requirements across all functional disciplines. Corresponding plans for DM should be included in the Systems Engineering Plan.
