What is Systems Engineering?
![Page 2: What is Systems Engineering? - IRSE - What is Systems... · Systems Engineering for Train Control and Communications: People, Process and Product University of Birmingham, 14th April](https://reader030.fdocuments.us/reader030/viewer/2022021509/5b0cc7e37f8b9abc0a8cb449/html5/thumbnails/2.jpg)
SE according to INCOSE
The International Council on SE (INCOSE) defines SE as follows:
“an interdisciplinary approach and means to enable the
realization of successful systems
“It focuses on defining customer needs and required
functionality early in the development cycle, documenting
requirements, then proceeding with design synthesis and
system validation while considering the complete problem”

SE helps to forestall systems problems
A system is any
combination of assets,
equipment, people,
procedures, software
and data designed to
work together for a
common purpose
A railway is a system
• Made up of many
smaller systems

Myths and realities about SE
Myth: SE is about
connecting up
computers
Reality: SE may
be thought of as
“the business of
getting the parts
of the railway to
work together to
do what we want
them to”
![Page 8: What is Systems Engineering? - IRSE - What is Systems... · Systems Engineering for Train Control and Communications: People, Process and Product University of Birmingham, 14th April](https://reader030.fdocuments.us/reader030/viewer/2022021509/5b0cc7e37f8b9abc0a8cb449/html5/thumbnails/8.jpg)
Myths and realities about SE
Myth: SE is a well-
defined discipline
Reality: There are
different views
on precisely what
SE is, which is
distracting and
inconvenient, but
there is enough
agreement to
work with

Myths and realities about SE
Myth: SE is just
common sense
Reality: SE
provides proven
and well-grounded
methods and to
put some common
sense ideas into
practice and a
framework within
which to apply
them

Myths and realities about SE
Myth: SE is
something
completely new
to rail
Myth : Rail
projects have
always done SE
Reality: SE
overlaps existing
rail engineering
practice but goes
beyond it
![Page 11: What is Systems Engineering? - IRSE - What is Systems... · Systems Engineering for Train Control and Communications: People, Process and Product University of Birmingham, 14th April](https://reader030.fdocuments.us/reader030/viewer/2022021509/5b0cc7e37f8b9abc0a8cb449/html5/thumbnails/11.jpg)
Myths and realities about SE
Myth: You can
import
conventional SE
into rail
unchanged
Myth : Railway SE
is something apart
Reality: Railway
projects should be
prepared to adapt
conventional SE
approaches but
only where there is
good reason to
deviate from
established,
proven methods

Concluding remarks
17
SE offers a reservoir of good practice that has been
proven in other sectors to address issues which can be
problematic for railway projects, including:
› getting the requirements right
› managing interfaces
› avoiding disappointment with the performance of the
finished project t
The railway industry is accumulating an increasing
amount of experience in adapting this practice and
applying it successfully
SE offers effective and applicable weapons in the
struggle to deliver high-quality railway systems at
reasonable cost
