\Gsection{LEAN and Supportive Processes in General}

LEAN product development delegates responsibilities as much as possible to 
the experts.
The management facilitates and stimulates the experts to operate
towards the goals using the LEAN principles.
The way of working is highly pragmatic,
where the goal dominates over the means.
In many cases no complicated computer tools and repositories are used.

Co-location in a larger room is common.
In this room wall space is used to visualize plans and schedules,
with low-tech means such as paper, pens, or magnetic boards.
The components or a prototype of the system can be present in the room
(keep the distance small!).

In LEAN manufacturing and LEAN product development A3's are used
to document and communicate, as discussed in the next section.
A3 is an European standard paper size of $297*420 mm$.
