Specifically about getting people joining the IR to already have their assigned speciality and first moves ready to go and to begun, as a way to support the incident handler. There's really big benefits to studying the metrics of specific incidents you have to the minute by minute level. So much time saving to be made, accuracy to be enforced and duplication to be reduced.
You can find there's less time wasted in an incident dividing out jobs or lost go inevitable context switching to join the incident. There's already searches, people and clarity about what should mostly likely be done in the first few mins, even though the plan will change and details initially are probably scare. It's really effective and cuts MMTx down a huge amount.
Obviously then the handover itself is a vital part in IR to get done accurately and with speed. So that flows into all of the above. It's a really good paper for thinking through workflows
I must get around to writing it up some day.
