And people do these things naturally all the time in large orgs and small. Visit a local PTA or a city council meeting with a copy and play bingo if you don’t believe me.
It only reads like a hoax because it’s all in one place.
But then, that depends on the who the guide targets, and may not be as important during an active war as it looks like in peace time.
If I wanted to convince most people I were not stupid or incompetent I would:
1. point out problems with their plans
2. argue about precise wordings as pedantry is seen as the sign of a precise intelligence.
3. be reasonable and urge reasonableness, surely the incompetent would not be reasonable.
4. talk about potential ramifications of decisions made going against organizational goals.
etc. etc. in short many of the methods that will allow you to shut down progress also help bolster your own reputation for intellectual rigor and understanding of issues from all sides.
Sure you won't be seen as a fiery genius, but a sagacious counselor - that's good enough.
But anyway, the non-hoax better strategy for a saboteur is exactly doing whatever destructive acts come naturally to people. So a real guide would probably have those same topics.
