Appendix D. Systems Engineering Management Plan

D.1 Purpose and Use

The purpose of this appendix is to provide an annotated outline for a SEMP for use by NASA programs and projects in planning the technical effort whether it is required for in-house or contracted projects. The SEMP outline provides guidance for the format and content of a project SEMP. The SEMP is the technical planning document for systems engineering. The SEMP is designed to be an integrated technical planning document for the conduct and management of the required technical effort. The resulting technical plan represents the agreed-to and approved tailoring of the requirements of the SE NPR to satisfy project technical requirements. The plan is used by the technical team responsible for generating technical work products to integrate and manage the full spectrum of technical activities required to engineer the system covered by the SEMP. The SEMP should be coordinated with the project plan for integration of the technical planning and modifications related to the allocated resources including cost, schedule, personnel, facilities, and deliverables required. The SEMP also will be used to evaluate the team's technical approach, to make technical risk assessments, and to measure progress.

D.2 Terms Used

Terminology is a key factor in ensuring a common understanding of the technical effort to be accomplished. Terms used in the SEMP should have the same meaning as the terms used in the SE NPR.

D.3 SEMP Preparation

D.3.1 Outline Use

The SEMP outline in this appendix is guidance to be used in preparing a project SEMP. For a small project, the material in the SEMP can be placed in the project plan's technical summary and this annotated outline be used as a topic guide. D.3.2 Tailoring and Customization

Program and project tailoring and customization need to be consistent with Paragraph 2.2 of this NPR. The SEMP is to include documentation of any tailored requirements. Significant customization of SE processes should also be documented in the SEMP.

D.3.3 Surveillance-Type Projects

For projects with significant portions of the engineering work contracted out, the SEMP should scope and plan the NASA project's implementation of the common technical processes before, during, and at the completion of the contracted effort. This should include planning the technical team's involvement in RFP preparation, in source selection activities, and in acceptance of deliverables. The interface activities with the contractor, including NASA technical team involvement with and monitoring of contracted work, should be a focus of the SEMP.

D.4.4 Applicable Documents

This section lists the documents applicable to SEMP implementation and describes major standards and procedures that the technical effort needs to follow.

D.4.5 Technical Summary

This section contains an executive summary describing the problem to be solved by this technical effort.

D.4.5.1 System Description

This subsection contains a definition of the purpose of the system being developed and a brief description of the purpose of the products of the product layer of the system structure for which this SEMP applies. Each product layer includes the system end products and their subsystems and the supporting or enabling products and any other work products (plans, baselines) required for the development of the system. The description should include any interfacing systems and system products, including humans, with which the system products will interact physically, functionally, or electronically.

D.4.5.2 System Structure

This subsection contains an explanation of how the technical portion of the product layer (including enabling products, technical cost, and technical schedule) will be developed and integrated into the project piece of the work breakdown structure and how the overall system structure will be developed. This subsection contains a description of the relationship of the specification tree and the drawing tree with the products of the system structure and how the relationship and interfaces of the system end products and their life-cycle-enabling products will be managed throughout the planned technical effort.

D.4.5.3 Product Integration

This subsection contains an explanation of how the product will be integrated and will describe clear organizational responsibilities and interdependencies whether the organizations are geographically dispersed or managed across Centers. Project integration includes the integration of analytical products.

D.4.5.4 Planning Context

This subsection contains the programmatic constraints (e.g., NPR 7120.5) that affect the planning and implementation of the common technical processes to be applied in performing the technical effort. The constraints provide a linkage of the technical effort with the applicable product life-cycle phases covered by the SEMP including, as applicable, milestone decision gates, major life-cycle and technical reviews, key intermediate events leading to project completion, life-cycle phase, event entry and exit criteria, and major baseline and other work products to be delivered to the sponsor or customer of the technical effort.

D.4.5.5 Boundary of Technical Effort

This subsection contains a description of the boundary of the general problem to be solved by the technical effort, including technical and project constraints (governing NPR's use of heritage hardware, predefined interfaces, cost, schedule, and technologies) that affect the planning. Specifically, it identifies what can be controlled by the technical team (inside the boundary) and what influences the technical effort and is influenced by the technical effort but not controlled by the technical team (outside the boundary). Specific attention should be given to physical, functional, and electronic interfaces across the boundary.

D.4.5.6 Cross-References

This subsection contains cross-references to appropriate nontechnical plans that interface with the technical effort and contains a summary description of how the technical activities covered in other plans are accomplished as fully integrated parts of the technical effort.
