System Deployment is not a phase in the traditional systems engineering lifecycle. It is a separate phase that occurs after the system has been developed and tested.

Requirements engineering is the process of defining the system's functionality and performance requirements. This includes identifying the system's stakeholders, understanding their needs, and translating those needs into a set of requirements that the system must meet.

Political risk is not a type of risk in systems engineering. It is a type of risk that is associated with the political environment in which the system is being developed or operated.

Project management is the process of planning and managing the system's development. This includes defining the project scope, schedule, and budget, as well as managing the project team and resources.

Risk acceptance is not a technique for managing risk in systems engineering. It is a decision to accept a risk and not take any action to mitigate it.

Configuration management is the process of controlling and tracking changes to the system. This includes identifying and documenting changes, as well as managing the impact of changes on the system's design, development, and operation.

Hierarchical architecture is not a type of system architecture. It is a type of organizational structure.

System integration is the process of combining the system's components into a working system. This includes testing the system's components together, as well as integrating the system with other systems.

Unit testing is not a type of system test. It is a type of software testing.

System deployment is the process of installing and configuring the system in its operational environment. This includes preparing the system for operation, as well as training the system's users.

Software development tool is not a type of systems engineering tool. It is a type of software engineering tool.

Systems engineering management is the process of planning, organizing, and controlling the system's development. This includes defining the project scope, schedule, and budget, as well as managing the project team and resources.

Agile process is not a type of systems engineering process. It is a type of software development process.

Systems engineering modeling is the process of creating a representation of the system. This can be done using a variety of techniques, such as mathematical modeling, graphical modeling, and simulation.
