How many t-shirts in your next iteration?

So considering my last post on t-shirt sizes and burn-downs , how do you decide on how many t-shirts to take on in the next iteration? If you assign some value to each size I guess it is easy since you have your velocity to use. But I heard another interesting Read More...

Software development at the fish market

The Fish market at Pike place is famous for its flying fish. I was there this weekend for the second time in a few weeks (benefit from having friends and family visiting from Sweden). But it is not the flying fish that make the show interesting I think. Read More...

Adding days to an iteration (sprint)

In Scrum you never extend a sprint. Read that again. Never . So why do some teams extend their sprint a few days sometimes? I think the most common reason is there is some functionality that is almost done and it feels better delivering "in a few days" Read More...

Second Generation Lean Product Development

Do you want to do a good job or do you want to go home?
