I Stand Corrected

My last blog was me ranting about non-fiction "idea" books burying their key point too deeply - forcing me to read too much of the book before I could tell if it would be worthwhile.  One book I complained about was The Checklist Manifesto by Gawande. I realize now I was wrong.

If you bought a book titled The Checklist Manifesto, what would you think it was about? Checklists - right. And would the book have been in favor of checklists? - Yes! Of course! So there it is. The key idea of this book is that checklists are great. And this key idea wasn't buried deep in the book - it was right there on the book's cover.

The problem is, I assumed there would be more and kept looking, thinking that the golden nugget would be on the very next page. But no - the golden nugget was sitting on the book cover and I had just passed right by it. It turns out that the rest of the book was about medical and aviation stories where lives were saved through the development and use of checklists.

Part of me wants to start a new rant on people writing books based on one idea that could be said in 3 words: "Checklists are great". But just maybe there is something more to this idea and it deserves more than 3 words - even if it is simple.

I was tutoring a student in statistics last semester. He was an engineer and plenty smart, but he was struggling in his class. The exams involved word problems and were quite confusing for the uninitiated. After our sessions, he ended up doing well in the class and I think I really helped him. I think my best advice to him on the subject was this - I told him to go through this process on every exam problem: 1) Determine what kind of problem it is. You do this by looking at the data itself and looking for certain key words in the question. 2) Go to the spot in the software that addresses that type of problem - he should already have mapped out the software to know where to go for each type of question.  3) See what information the software asks for and see if it fits the data provided. 4) Assuming that is a yes, go to a prepared list of things the professor will look for to get full credit.

I know from talking to several students in the class that they study and learn the material, but during the exam, they get confused by the word problems and end up wasting most of the exam time wondering what to do or going down wrong paths. They end up not being able to finish the exam in time. My method takes about 3 minutes - if the person is prepared ahead of time - and should allow a student to finish the exam in about half the time provided.

The secret to my method was a checklist. Not that I thought of it as a checklist at the time, but that is what it was. I thought of it more as a decision tree, which is just an enhanced checklist.

All of this makes me wonder - where else could I use checklists? And why don't I use them more often? What kind of problems can be addressed with checklists? Do some people internalize checklists quickly and does this give them a huge boost in productivity and learning? (My guess is yes on that one) This sounds like the subject of a new blog.
