There are roughly 20 CofE Dioceses now doing some form of Mission Action Planning, an approach to mission strategy pioneered by York and London under David Hope's leadership. But it's quite a faff wading through 20 sets of Diocesan documents, all of them different, to work out what MAPping is really about, how it works, and how to do it.
Good news then: 'How To Do Mission Action Planning' has just been published by SPCK. It's written by Mike Chew and Mark Ireland, and there's a bit more blurb here, along with a list of the Dioceses known to be doing Mission Action Planning. There's quite a handy dedicated website, which explains more about it, who's doing it, and has various examples from different churches, which is a good starter for 10.
Interestingly, our Archdeacon recently asked all her churches whether they'd be interested in developing some kind of parish action plan. Quite a few said yes. So this might be quite timely.
