THE WHOLE PROCESS
1. Describe the steps of the workflow
2. For each step, think about possible levels of quality of service (QoS)
1. Try to find the simplest possible first,
2. Then add more sophisticated options
3. Start “slicing” stories
1. try to create one vertical, end-to-end slice first
2. Then, define new stories that add functionality by small steps
THINGS TO REMEMBER
• Aim to end-to-end slices
• The simplest possible solution is often more simple than you think
• When taking the slice into a sprint, you can slice it into tasks using the same technique, since...
USER STORIES ARE FRACTALS

FINAL ADVICE
• Once slice when you are ready to eat
