The chart below provides a clear overview of the roles and responsibilities of the Project Manager, Systems Engineering, and PP&C, highlighting areas of overlap between Systems Engineering and Project Planing and Control (PP&C).
There are three sets of common technical processes in Systems Engineering Processes and Requirements:
- System design
- Product realization
- Technical management
The processes in each set and their interactions and flows are illustrated below:
- Processes 1 through 9 represent the tasks in the execution of a project.
- Processes 10 through 17 are crosscutting tools for carrying out the processes.
System Design Processes:
The four system design processes shown are used to:
- Define and baseline stakeholder expectations.
- Generate and baseline technical requirements.
- Decompose the requirements into logical and behavioral models,
- Convert the technical requirements into a design solution that will Satisfy the baselined stakeholder expectations.
Product Realization Processes:
Applied to each operational/ mission product in the system structure starting
- from the lowest level product
- working up to higher level integrated products.
Processes used to:
- create the design solution for each product (through buying, coding, building, or reusing)
- verify, validate, and transition up to the next hierarchical level
