Except for the last one, the other two are from my experiences needing to write those docs.

For decision doc, do you prefer tracking stakeholders comments scattered in multiple places (and also track down the closed comments), or have a single places to read their concerns and address them explicitly as part of the decision making process?

For investigation doc, have you not had the need to hand off to someone else, maybe because you need to go on vacation, or you need to hand off to a colleague in a different time zone? How does the one who took over know what was done for a line "we investigated this hypothesis and it didn't work"? What if the action taken to validate the hypothesis is not comprehensive or the conclusion from the actions is not correct?
