I just looked at my projects list in order to answer the question, and found out that just by looking at the project, I could recall what the status is, for most of the projects. There are only a few projects which required several things. I had already noted them all in the project notes, so that I could have checked each one of them. Right now I did a short review for five minutes, but during weekly review I may take about fifteen to twenty minutes for actions and projects together (but it varies a lot, if some projects require unusual thinking, some of which I feel should be done right then).
Your set of projects may have different statistics. Can you let us know approximately how many such projects you have, where you look at them and cannot recall the status, even when you look at all the notes? Those are the ones which perhaps require some extra thinking and note-taking for streamlining.
For SMDB, my questions are (*) Is this still relevant even as SMDB or should I trash it? (*) has it become relevant or essential now? (*) Even if not, can I see some value in undertaking it as a project now? (*) Is it morphed into something else and have I captured that or should I do it now? Roughly 20 to 30 minutes, but varies a lot. Sometimes I just skim over them, and sometimes I engage more actively with this part of the review. Well, sometimes it helps to have these questions in mind, but it's not constrained by these questions and these questions are not an algorithm. It is mostly just looking at it and intuitively deciding where it is and should be in my landscape.
