Management Issues in Systems Engineering
4.2 Managing the Systems Engineering Process:
The Systems Engineering Management Plan Systems engineering management is a
technical function and discipline that ensures that
systems engineering and all other technical functions
are properly applied.
Each project should be managed in accordance
with a project life cycle that is carefully tailored to the
project's risks. While the project manager concentrates
on managing the overall project life cycle, the
project-level or lead system engineer concentrates on
managing its technical aspect (see Figure 7 or 8). This
requires that the system engineer perform or cause to
be performed the necessary multiple layers of
decomposition, definition? integration, verification and
validation of the system, while orchestrating and
incorporating the appropriate concurrent engineering.
Each one of these systems engineering functions requires application of technical analysis skills and techniques.
The techniques used in systems engineering
management include work breakdown structures,
network scheduling, risk management, requirements
traceability and reviews, baselines, configuration
management, data management, specialty engineering
program planning, definition and readiness reviews,
audits, design certification, and status reporting and
The Project Plan defines how the project will be
managed to achieve its goals and objectives within
defined programmatic constraints. The Systems
Engineering Management Plan (SEMP) is the
subordinate document that defines to all project
participants how the project will be technically managed
within the constraints established by the Project Plan.
The SEMP communicates to all participants how they
must respond to pre-established management practices.
For instance, the SEMP should describe the means for
both internal and external (to the project) interface
control. The SEMP also communicates how the systems
engineering management techniques noted above
