Why Systems Engineering?

~5000 sensors, ECU‘s, etc.

communicating over 9000

connections via 1,000,000+

types of messages, performing

2000+ functions—with each tail

number different

~10M LOC, 40-60 ECU‘s, ~5000

parameters, ~30,000 functions

(typical engine controller ~4000

functions)

An Oregon man

discovered that his year-

old Toshiba flat-screen TV

was emitting an

international distress

signal (121.5 mhz) picked

up by a satellite, leading a

search and rescue

operation to his apartment

Resulting In Recalls

A sample list from the NHTSA recalls database

…recalls 1.3 million vehicles where engine controller may

develop solder joint cracks due to vibration

…recalls 1021 vehicles with automatic rear lid with leaking gas struts could cause injury…software update

…recalls 3.6 million vehicles…speed control switch leaks and overheats

…recalls 10,113 vans…brake lights don‘t come on after first time; brake control software update

…recalls 437 vehicles…seat sensor calibration error doesn‘t turn on air bags

[http://www.nhtsa.gov]

Failing to manage cross-

domain interactions/interfaces

show up as recalls later

Requirements document

interactions/constraints

(analysts claim the majority of

warranty issues trace back to

failures to define and keep up

with requirements).

Requirements outside the

lifecycle don‘t solve the

problem

20 million vehicle recalls

in the US in 2010 (more

recalls then sold).

Each recall costs

$100/vehicle/recall ($2

billion/year) in direct costs

The significant problems we face

cannot be solved at the same

level of thinking we were at

when we created them Albert
