==== The Systems Engineering Process ====

{{:francois:boulot:system_design:system_engineering_process.png?direct&400|Systems engineering process}}

**Systems engineering controls** are used to track decisions  and  requirements,  maintain  technical
baselines, manage interfaces, manage risks, track cost  and  schedule,  track  technical  performance,
verify requirements are met, and review/audit the progress.

==== The System architectures ====

Usable system architectures can be:

  * functional
  * physical
  * system

These architectures are necessary components of the systems engineering process.

The //Functional Architecture// identifies and structures the allocated functional and performance
requirements.

The //Physical Architecture// depicts the system product by showing how it is broken down into 
subsystems and components.

The //System Architecture// identifies all the products (including enabling products) that are 
necessary  to  support the  system  and,  by  implication,  the  processes necessary for 
development, production/construction, deployment, operations, support, disposal,
training, and verification.

==== Responsabilities ====

Responsibilities of systems engineers include:

  * Development of a total system design solution that balances cost, schedule, performance, and risk
  * Development and tracking of technical information needed for decision making
  * Verification that technical solutions satisfy customer requirement
  * Development of a system that can be produced economically and supported throughout the life cycle,
  * Development and monitoring of internal and external  interface  compatibility  of  the  system  and  subsystems  using  an  open  systems approach,
  * Establishment of baselines and configuration control
  * Proper focus and structure for system and major sub-system level design IPT
