A Systems Engineering Management Plan (SEMP) is a document that addresses a contractors overall systems engineering management approach. It provides unique insight into the application of a contractor’s standards, capability models, configuration management, and toolsets to their organization. This is different from a Systems Engineering Plan (SEP) which should address SE aspects on a particular program or project. The SEMP is usually written in response to a government SEP and shall describe a contractor’s proposed efforts for planning, controlling and conducting a fully integrated engineering effort.
Data Item Description: System Engineering Management Plan (SEMP)
The SEMP shall include the following: 
- Cover/title page
- Document history
- Table of contents
- An introduction that includes the document’s purpose, suggested audience, and list of key terms
- An executive summary of the document’s content
- An overview of the proposed SE approach. See below
A Contractors SEMP should address the following: 
- Organization of the development team, along with their physical location and facilities needs
- Technical environments for a project and how they will be managed. It should also discuss the interaction with the pre-production and production environments.
- Description of the evaluation and decision-making process to be used when resolving technical questions
- System Engineering Methodology:
- Configuration Management: Include a description of how project configuration items (e.g. source code) will be managed.
- Requirements Verification and Validation: Include a description of how the Use Cases will be clarified and expanded, requirements validated, and updated requirements reviewed and approved by the project office.
- The Architecture and Design Process (both logical and physical design), including how issues will be discussed and resolved.
- The software development methodology to be used that reflects the requirements (for iterative builds and incremental releases).
- The hardware development and configuration methodology to be used that reflects the requirements (for iterative builds and incremental releases).
- The build management process used to create and manage builds.
- The testing process to be used that encompasses the requirements.
- Description of how external interfaces will be developed and managed.
- Description of how data conversion development will be performed and managed.
- Implementation Planning to include a description of how you will manage the deployment of system functionality, the training required for both end-users and technical staff, the coordination/communication needed to prepare the target environments.
- Production Support strategy
- A description of how production support will be done concurrently with development, given the incremental release requirements for the project.
Note: Many contractors will call their SEMP a Systems Engineering Plan. The names are often uses interchangeable so check beforehand.
