The other reasons why processes are not adopted is that most employees are not thinking in terms of 'processes'. Secondly typical process/BPM tools are geared towards I.T. rather than regular workers.

Both problems can be solved by gearing tools towards end-users rather than I.T. and allowing processes to emerge from lower-level constructs like (say) discussion threads that workers normally participate in. This would gently steer workers towards a process mindset.
