| This book is meant to help
both customers and suppliers to improve the quality of acquisition processes.
The ISPL concept of an acquisition process helps to make explicit the management
of expectations and risks. By sharing terminology and methodology, customers
and suppliers achieve a better communication about the aims of projects
and services and the means to achieve them.
Many IT failures are caused
by unclear or bad agreements and insufficiently organised expectation management
between customers and suppliers. Following a well-defined process, well-understood
by both customer and supplier, has a beneficial effect on the quality of
the agreement that is reached. A better understanding of the process also
leads to better control, and thus a more effective use of resources.
ISPL provides a well-defined
process that can be used by both customers and suppliers to structure their
acquisitions. ISPL also provides checklists that can be used as a reference
in concrete acquisitions.
