I was in BCP/DRP for 20 years and lists/procedures/scripts are definitely the way to go. Everything we did had a procedural list. Everything we worked on was documented and timelined for specific reasons.

1. A list lets you move through a process faster and more accurately.
2. Everyone knows what everyone else is doing.
2. Problems found, improvements made, procedures changed are all documented.
3.Timelines help to forecast downtime. If there is a crash, folks want to know when the system will be back,if it is planned, downtime can be scheduled with end users and shareholders and tech support time.

Use, a digital recorder to document everything you do - good or bad. It is easy to forget things when you're up to your eyeballs in work

Always have a debrief, even if you work alone. Grab a coffee and go back over the notes. It helps to understand why something was done and its relevant consequence.

You will be surprised how much more you are aware of problems and resolutions when you go back and document them.Add them to a CMS with lots of tags for future reference.
