SYSTEM ENGINEERING PART 1
(CHAPTER 1)
System
integrated composite
an integrated composite of people, and processes that provide a capability to satisfy a stated need or objective.
System Engineering
consists of 2 significant disciplines
technical knowledge domain
in which the systems engineer operates
systems engineering management
logic sequence
a logical sequence of
activities and decisions
that transforms an operational need into a description of system performance parameters and a preferred system configuration.
Systems Engineering Management
accomplished by
integrating 3
major activities
D
evelop
Development phasing
controls
the design process and provides baselines that coordinate design efforts
2 major purposes
controls
controls the design effort
by developing design baselines that govern each level of development
connection
major connection between the technical management effort and the overall acquisition effort
it interfaces w acquisition management by providing
key events
in the development process, where design viability can be assessed.
viability of the baselines developed = major input for acquisition management Milestone (MS) decisions.
3 distinct levels/stages
Concept Level
produces a
system concept description
System Level
produces a system
description in performance requirement terms
Subsystem/Component Level
produces
a set of
subsystem and component product performance descriptions
a set of
corresponding detailed descriptions of the products' characteristics
SEP
System Engineering Process
provides
a structure for solving design problems and tracking requirements flow through the design effort
the
heart
of systems engineering management
purpose
provide process
provide a structured but flexible process that transforms requirements into specifications, architectures, and configuration baselines
the discipline of this process provides the control and trace-ability to develop
solutions
that meet customer needs
may be
repeated
one or more time during
any phase
of the development process.
LCI
Life Cycle Integration
involves
customers
in the design process and ensures that the system developed is
viable
throughout its life
purpose
to ensure that the
design solution
is
viable
throughout the life of the system
includes planning associated w
product and process development
, as well as
integration of multiple function
concerns into the design and engineering process
product cycle-times + the need for redesign and rework are reduced
