I typed out detailed policy and procedure for all departments, With checklists and potential problems, Who to report to etc etc. It was a big job that took three weeks full time to get everything sorted.
I had a copy of every departments Processes in a Binder in my office. Plus every department had a copy of their Policy and procedure in their department area; Easily accessable.
When new members are trained, The person responcible for training will show them the policy and procedure and ask them to refer to it if they ever have a problem: If there's no solution to their problem in the Procedure, They can talk to their Department head, The department head talks to me, And then I add it to the Procedure. There's a sheet on the last page that has FAQ's/ Common Solutions.
The procedures may not be carried out to the T, But that's the staff perrogative, They're told exactly how to do the job, So if they do the job incorrectly and somehow end up in a situation: It's their fault for not properly following set procedure.
I think it's important to have procedure that covers everything, Because common sense isn't that common. And it's an unfortunate fact that sometimes you have staff that don't follow procedure. If it's physical and on paper, As apposed to oral, It seems more real.
It's easier to sit them down, Get out the binder and show them; "Here's where you went wrong, Next time follow proper procedure because XYZ" It just seems more official than you telling them that they're doing something wrong because you said so.
