\chapter{Introduction}

Start-up companies operate in an environment,
where their market is not clear, nor their business model.
At the same time, the contours of their solutions
are still shaping up and the technology,
production and delivery process and
the supply are all under development.
In other words, everything is moving simultaneously.
Start-ups need persistence and focus
to spend their limited resources well,
while they also need to be open minded and
responsive to market and business needs.
How can start-ups use the systems engineering knowledge
in a way that it fits this context?

Interestingly,
large organizations may have similar needs,
when disruptive developments take place.
A clear example is defense,
where drones and electronic warfare disrupt
existing doctrines.
This tutorial guides the participants to
a highly iterative systems engineering process
with the continuous challenge to do just enough.
The purpose is to facilitate the required level of responsiveness,
while at the same time bring
sufficient anticipation of the
many enabling systems that need development.
