Planning poker

What is planning poker and who should be included in the process? Should the Product Owner, ScrumMaster, analyst take part in sizing? Do you size dev and testing separately? ... and many more questions.

The event will be held in the upstairs room at The Plumbers Arms. The sessions are informal and we are happy for you to eat the pub grub / drink during the meetup (the pies are pretty nice).

The pub's site gives directions: http://www.taylor-walker.co.uk/pub/plumbers-arms-belgravia/c0685/

Here's their map:
