Relaties tussen leveranciers en uitnesteders: een lange weg naar co-makership.
Literature survey,

Components should be delivered Just-in-Time to be able to produce
Just-in-Time. This makes high demands upon suppliers. In this report the
characteristics and the benefits or disadvantages of Just-in-Time will be
described.
An important characteristic and also a condition for
Just-in- Time is co-makership, a long-term relationship between a
sub-contractor and a limited number of suppliers. Not all products and
branches of industry are suitable for co-makership. The characteristics
and the benefits or disadvantages of co-makership will also be
discussed.
Besides Just-in-Time and co-makership the term sourcing is
frequently used in relationships between suppliers and sub-contactors.
Sourcing means the search and selection of suppliers for a product.
Various forms are used in literature like: sole, single en dual sourcing.
Por each form other arguments are used.
Before the selection of suppliers can be started, the degree of co-operation
between sub-contactor and supplier should be determined. In literature two
methods are found. These methods are described and compared with each other.
To find a suitable supplier a selection procedure is started, with a review
whether the supplier meets the requirements of the sub-contractor. After the
selection the supplier should be evaluated continually. The sub-contractor
uses mostly a selection or an evaluation procedure. A selection and
evaluation procedure used by Siemens is described.
After the right supplier has been selected a contract can be drawn up.
There are a few aspects which are useful to include in a contract. The
juridical aspects of comakership should also be taken into account such as
protection of know-how by patenting.
