The times of ''proper circumstances'' are gone as well as the times of
''business as usual''. Changing conditions of the economical and tech
nological framework also force information units to a general review o
f their orientation. In many cases their host organisation is facing t
hem with perspectives of a fundamental change either. This paper shows
how management strategies can provide solutions for libraries or docu
mentation units under such pressure of change. It focusses on business
reengineering, and the paramount role of a process-oriented informati
on management. As an option to handle the subsequent radical change, t
he outline of chaos management philosophy is given. It is shown that,
despite their different approaches, both strategies have process-orien
tation and promises of substantial impact in general.
