Separation of mechanism and policy. Among the major causes of our inability to experiment with, and adapt, existing operating systems is their failure to properly separate mechanisms from policies. (Hansen [1] has presented cogent arguments for this separation.) Such separation contributes to the flexibility of the system, for it leaves the complex decisions in the hands of the person who should make them--the higher-level system designer.</div></blockquote><div class=""><div class=""><br class=""></div><div class=""><span style="font-family: tahoma, arial, verdana, sans-serif; background-color: rgb(255, 255, 255);" class="">W.
