Systems Engineering and Project Management
The goal of project management is to plan and coordinate the work activities needed to deliver a satisfactory product, service, or enterprise endeavor within the constraints of schedule, budget, resources, infrastructure, and available staffing and technology. The purpose of this knowledge area (KA) is to acquaint systems engineers with the elements of project management and to explain the relationships between systems engineering (SE) and project management (PM).

Topics
Each part of the SEBoK is divided into knowledge areas (KAs), which are groupings of information with a related theme. The KAs in turn are divided into topics. This KA contains the following topics:
- The Nature of Project Management
- An Overview of the PMI Guide to the Project Management Body of Knowledge (PMBOK(TM))
- Relationships between Systems Engineering and Project Management
- The Influence of Project Structure and Governance on Systems Engineering and Project Management Relationships
The Nature of Project Management
Project managers and systems engineers are both concerned with management issues such as planning, measuring and controlling, leading, directing, and managing risk. In the case of project managers, the project attributes to be managed include project plans, estimates, schedule, budget, project structure, staffing, resources, infrastructure and risk factors. Product attributes managed by systems engineers include items such as requirements allocation and flow-down, system architecture, structure of and interactions among technical teams, specialty engineering, integration , verification and validation. The exact allocation of the SE and PM duties depend on many factors such as customer and stakeholder interactions, organizational structure of the parent organization, and relationships with affiliate contractors and subcontractors. See the article on The Influence of Project Structure and Governance on Systems Engineering and Project Management Relationships in this KA.
The activities of project management include the following (Fairley 2009; Forsberg et al 2005):
- Planning and Estimating
- Measuring and Controlling
- Leading and Directing
- Managing Risk
Measuring and Controlling
Measuring and controlling are the key elements of executing a project. Measurement includes collecting measures for work products and work processes. For example, determining the level of coverage of requirements in a design specification can be assessed by reviews, analysis, prototyping, and traceability. Effort and schedule expended on the work processes can be measured and compared to estimates; earned value can be tracked for this purpose. Controlling is concerned with analyzing measurement data and implementing corrective actions when actual status does not align with planned status. Additional information on measurement and control of technical factors can be found in the Measurement and Assessment and Control articles in Part 3: Systems Engineering and Management.
Leading and Directing
Leading and directing requires communication and coordination among all project stakeholders, both internal and external to a project. Systems engineers may be responsible for managing all technical aspects of project execution, or they may serve as staff support for the project manager or project management office. Organizational relationships between systems engineers and project managers are presented in the article Organizing Teams to Perform Systems Engineering in Part 5: Enabling Systems Engineering. Other organizational considerations for the relationships between systems engineering and project management are also covered in Part 5: Enabling Systems Engineering.
Managing Risk
risk management is concerned with identifying and mitigating potential problems before they become real problems. Systems engineering projects are, by nature, high-risk endeavors because of the many unknowns and uncertainties that are inherent in projects. Because new risk factors typically emerge during a project, ongoing continuous risk management is an important activity for both systems engineers and project managers.
Every aspect of a project may encounter potential and actual problems. Systems engineers are typically concerned with technical risk and project managers with programmatic risk. Sometimes, technical risk factors are identified and confronted by systems engineers and programmatic risk factors are identified and confronted by project managers, but without adequate communication between them. In these cases, appropriate tradeoffs among requirements, schedule, budget, infrastructure, and technology may not be made, which creates additional risk for the successful outcome of a project.
Additional information on risk management for systems engineering projects can be found in the Risk Management article in Part 3: Systems Engineering and Management
