This is a deck I use to introduce the notion of 'planning poker'. It uses Doggy Planning as found http://blog.tastycupcakes.com/2009/06/doggy-planning/ Furthermore, it contains some CC licensed images from Flickr. I use this presentation to show why relative estimates are important. For the doggy planning, I allow some discussion as to 'what on earth are we estimating here', and in the end end up with some metric to estimate. I only show the image of the dogs after the 'right questions' have been asked (e.g., "what kind of poodle is this?"). If you have any ideas to use this better, please let me know!

Editor's Notes
- For estimation, we use something called ‘planning poker’. Outline: - Why relative estimation? (I will not go into their function in scrum) - Planning Poker workings - Try it out! This presentation is based on http://blog.tastycupcakes.com/2009/06/doggy-planning/
- Goal of this slide: show the benefits of relative estimation The chicago skyline Points to make: - relative estimation is pretty easy - the larger the estimate, the lower the accuracy (there’s no need to argue over 31 or 32) image source: http://www.flickr.com/photos/atelier_tee/475960290/

- One deck, three rounds, one estimate
- - Introduce the problem - Estimate: We re-estimate if - estimates are off more than 1 step, or - ?’s are used Furthermore, we redefine if - estimates are too high (80 is high), so we split up the task - discussion shows we misunderstand this issue - Ideally, we end up with a unanimous verdict; if after three rounds we are still 1 step off, we average the cast esimates
- The deck uses a modified fibonacci sequence. Image: http://www.codinghorror.com/blog/archives/000981.html
