When will scrum die? Some people would say it's already dying. There's so much inauthentic, scrum being done, unprofessional, scrum being done in the world. Whereas scrum is part of what I call water scrum fall, where it's put within a predictive deterministic system. We're predicting when work will be finished.
When actually we’ve got so much work that where we don't know, what we don't know, that's really unauthentic. I see in those situations where the concept of done isn't even a concept there They think that done means we met the acceptance criteria when actually it's almost like the checklist for how we do things around here, the technical standards and the product quality standards, international standards, for example, that we might need to comply with.
What is the difference? By analyzing what should a scrum master be doing and what would a leader do, we can understand that there is not much difference. Why do I think leaders make good scrum masters?
The scrum master is now on the hook for the effectiveness of the scrum team. So the buck stops with the scrum master. And the reason that this was introduced, I believe, was to stop situations where scrum masters were asking lots of Socratic questions and doing lots of observation, which is a really good thing to do. But they were just watching this and bad behavior was happening on their watch. Unhealthy conflict was happening on their watch. The team’s performance was going down on their watch. And so it was felt that it was a good move to have somebody on the hook for the effectiveness of the team.
What level of travel is involved when people are producing your products and services? Are we getting components on the other side of the planet when they could have been sourced more locally and so on? So it’s quite a broad area and there’s lots of things you can do There are no silver bullets for this.
If you want to improve sustainability, consider it in terms of how you prioritize value, how you order your backlogs in scrum kanban, how you do your experiments and consider can we achieve more competitiveness in the market by providing a more sustainable product or service without increasing cost. Take your sustainable product, if in doing so, it’s going to cost them more. So there’s going to be some level of R and D to try and figure this out, but that would be my nudge on sustainability.
Today I want to tell you a little bit of a story about a festival in England. You know what the English summertime is like. We went to a thing called Pub in the Park in Marlow, and it was raining. It rained really heavily. And we were wondering what to eat and we saw these different stalls and we were disappointed with the food we were getting. I was waiting a long time for my pizza, but I noticed something that they weren’t overloading themselves because they were taking their time taking the orders. They slowed down the arrival rate of orders coming to the pizza stall. So it meant, there was really like a very good flow, that The people were working completely in tandem.
I could see there was a constraint there on the pizza oven. They probably could have done with two pizza ovens and that person seemed to be under a lot of pressure. But they didn’t take on any more work than they had the capability to take on. They were fully utilized but they first optimized their flow.
It was like a really tiny portion for a lot of money. And so we said, let’s get some pizza. And we went to a pizza stall and there was a big, long queue. I asked my family to go in under a tent and I just had an umbrella, luckily, and I had rain gear and I waited in the queue and I was waiting for quite a while.
