This is no easy thing to do. Much of the organizations’ processes will be institutionalized. It will take a lot of very insightful investigation to uncover many of the subtle aspects of their processes.

Get out Viso and flow their entire core processes from cradle to grave. Then find out what processes take place outside their primary roles and flow them out fully (some of these might include processes for Reporting, Extraordinary Event Handling, Afterhours, VIP, Disaster Plans, etc).

Once you have done this, you can then map the processes against each other and make some best-of-breed decisions. In this step, you will need a lot of management support.

At the end, there will be some unhappy people around the table. That is the nature of the beast.
