We are beginning to experience the new Custodianship model first hand, and I think we can lead the way in this to help other teams at MYOB be successful in this approach too. Here are some ideas/thoughts I have had. ..

We need both sides to be empathetic. Custodians will naturally be biased towards their way of doing things, and this may result in conflict when someone makes a pull request. So when you are involved in this process please take a minute to put yourself in the other sides shoes, and be empathetic.

Custodian · Expects design and vision to be maintained. · Expects code quality to remain the same or even improve. · Probably busy when pull requests are made so may not be able to process them within the hour. We may need an SLA - eg 24 or 48 hours. · Expects not to be surprised by big changes that have not been discussed.

Contributor · Expects some help as the may not be familiar with design, code and expectations. · Expects pull requests to be processed quickly, but should also acknowledge that the Custodians may be busy and can’t do it immediately. · Does not want to be hindered by a process.

Guidelines · Every change should be managed by a pull request no matter how small. If we allow direct pushes to occur this may be used to get changes in quickly. · Should have SLA around pull requests. A week is probably good enough. 24 or 48 hours? · We should NOT rely on the pull to be processed to be able to run some tests. · We need to acknowledge that this process will incur some cost on both sides. So we can either go for big bang costs at the end of the process (ie. A big pull request), or we can make small investments from the start that will pay off when the pull request is made. I think the latter is the better approach. So this means: o Get the custodian involved early in inception phase. o Get designs and changes reviewed by Custodian o BA & QA need to collaborate as well this is not just a Dev thing. o Both teams need to factor this time in - I think it will pay off in the end when the pull requests are processed as there will be no suprises, and all expectations will have been met.
