Projected Service Availability (PSA) for ITIL Change Management

Hi All,

Hope everyone had a fabulous Easter and got lots of chocolate. I'm looking for some help with PSA's; I'm trying to improve the Change Management process in my workplace. I've already introduced formalised CAB meetings, change approval and an FSC and feel the next step would be to provide our users with a PSA to be issued via our Service Desk. I've just come back to work from maternity leave (have had a gorgeous baby girl - Molly) so it's been a while since I've had to write one. Could anyone point me in the direction of a sample PSA to remind me what they should ideally look like as really want to do the best for my users?

Ta muchly,

Vawns
