Chris, Per sprint, we spend 1 hour on Sprint planning, 2 x 1 hour on Refinement and 1 hour of Retro. Our daily standups with a team of 10 people will take about 15 minutes.
Our stories are mostly all researched beforehand and before/during refinement we also write down some steps it takes to implement it. This helps us to remember what we discussed when we implement it. We have 3 front-end and 2 back-end engs. so it differs who will be assigned
