Ensure that your core ITSM team and executive sponsor(s) have a consistent message on ITIL's value, plans, and implications in a language that will resonate with IT and non-IT audiences. As an example, be clear in your messaging that ITIL is not a silver bullet for all of your IT service delivery woes or even the "desired" future state -- rather it is a "compass" to that destination. To do this effectively, you will likely have to tailor your message based on the audience because IT professionals expect and likely require another layer of detail than a business user needs. From there, set clear expectations on who will be involved and what their role will be. Likewise, be sure that that all parties responsible for ITIL's success -- not just those in IT operations -- are exposed to ITIL awareness, education, and training.
