DateThe problem (no names, no customers)Name

Part 1. Mark up the assistant's draft. For each phrase, circle N (it came from my notes), A (it assumed something) or I (it invented something). Then tag each number M (I or someone measured it, and when), O (an operator said it) or A (the assistant supplied it).

#	Phrase from the draft	N · A · I	If it is a number: M · O · A, and the source
1		N A I
2		N A I
3		N A I
4		N A I
5		N A I
6		N A I
7		N A I
8		N A I

How many were N, A and I? Which invention would I have missed if I had not marked it?

Did it agree with my leading question? What did "three findings that would disprove it" give me?

Part 2. The go-see list. For each item: what I will look at, whom I will ask, and what I would see if my cause were true, and if it were not.

#	What I will go and look at	Whom I will ask	If my cause is true I see... / if it is false I see...
