What is systems engineering Structures and
disciplines the classic engineering
process Improves communication and provides a
shared vision of the need and solution Architects
both the process and product Reduces risk of cost
over runs, schedule slides and inferior products
5
Systems Engineering Basics View anything and
everything as a system Develop all four FRAT
views of each system Use the systems approach to
do anything Maintain a shared vision of process
and products
6
Apply SE to 3 types of systems
development and operating environment
process system
product system

Conclusions Systems engineering (SE) is a task
that should be performed as part of any
job. Practicing systems engineers specialize in
performing specific SE tasks and may not have
skills to perform all SE tasks Need someone or a
small team to mentor and continually improve the
practice of SE tasks
