First thing I would do is to not accept the premise of the presentation. Why would anyone think that you can shorten calls while not affecting customer service? It may very well be possible, but you need to verify it. The best way to start is to gather data in your call centre. Data on number, cause, type, length of calls. It maybe that shorter calls cause shortcut measures by agents to get people off the call. Or it maybe that there are concrete things you can do to remove the waste from a call. But base all of it on facts and data.
In my experience, after you gather the data, the presentation writes itself.
