Editing Workplace OS (section)

===Internal analysis===
In January 1995, four years after the conception and one year before the cancellation of Workplace OS, IBM announced the results of a very late stage analysis of the project's initial assumptions. This concluded that it is impossible to unify the inherent disparity in endianness between different proposed personalities of legacy systems, resulting in the total abandonment of the flagship plan for an AIX personality.<ref name="WorkplaceMicrokernelandOS"/>{{rp|19}}

In May 1997, one year after its cancellation, one of its architects reflected back on the intractable problems of the project's software design and the limits of available hardware.

{{quotation | quote=There is no good way to factor multiple existing systems into a set of functional servers without making them excessively large and complex. In addition, the message-passing nature of the microkernel turns out to be a poor match for the characteristics of modern processors, causing performance problems. Finally, the use of fine-grained objects complicated the design and further reduced the performance of the system. Based on this experience, I believe that more modest, more targeted operating systems consume fewer resources, offer better performance and can provide the desired semantics with fewer compromises.|source=Freeman L.
