Given the overriding importance of data presentation (read graphing skills) to the effectiveness of the modern “knowledge worker” it was decided that the book club would cover a book on that very subject.

Stephen Few’s Show Me The Numbers was chosen after a review of reviews (a meta-review?) on Amazon, which seemed to suggest that Edward Tufte (the giant of the field) might not be the best read for business-centric readers tied to Microsoft Excel.  Key points that stood out from the rest of the text included the “4 chunk rule” (describing the maximum limit of themes or aggregations of data people can process at a time) and the fact that when it comes to graphs, it’s the shape of the data that counts.  Not the particular values.  (If the values are critical… the data should be presented as a table!)

This review is the first (thus far at least) to be summarized in two files — a Word document and a PowerPoint slide deck — due to the benefit not just of explaining what the text was saying, but showing it visually as well.

As always, if you find the review to be useful, please consider supporting the author by purchasing the book.

Show Me The Numbers (summary)

Show Me The Numbers (PPT)

(originally written Jan 25)

I’m in training pretty much the whole week — which fact one of my horoscopes must’ve predicted.  I mean, there are so many of them floating out there, that one of them must’ve been right!

 

The past couple days covered FMEA, an engineering topic so obscure I’ll give the unabbreviated name (Failure Modes and Effects Analysis) and immediately move the story forward.  We were fortunate to have had a great teacher — a grizzled veteran of industry who tossed out great one-liners such as:

 

"an FMEA without action [items] is called Charmin — because if you print it on softer paper, THEN it has a function"

         (Charmin is a brand of what polite butlers would refer to as ‘bathroom tissue’)

 

"product development is a failure factory"

 

          ….as well as the sentence clause,

" — not that it ever happens here — "

 

delivered each time he described a wince-worthy product development process which had indeed, never happened here. 

 

He also described how a good FMEA meeting ideally comprises the design engineer, a reliability engineer, a facilitator, and a fourth engineer playing the role of "The Opposer".  (Or as they say in the Biblical Hebrew, "Satan".    )

 

 

It turns out this fellow was a co-op student at Ford when FMEA’s were brought there in the 1970’s, due to the tendency of the Ford Pinto to explode in rear-end collisions, as a $4-per-vehicle fix was deemed too expensive.  Though to be fair, that doesn’t account for inflation; according to an unverified internet source, such a fix would cost a whopping $20 today.  That totally changed your perspective, didn’t it? 

 

In crisis, Ford brought in experts from NASA — which had regrettably extensive experience with exploding products — who brought in this FMEA technique.  So, as our teacher wryly noted, FMEA’s are actually rocket science, ported over from the Space Program which invented them.  The very Space Program which employed a colleague on an unsuccessful Mars Lander.  (Not the one which missed the planet; the other one, which stopped phoning home.)

Come to think of it, it’s turning out to be quite the lesson week for me.  At the weekend gold show — bereft of decent freebies, apart from some USB drives — the busiest company booth was from some no-name junior exploration company (read "investing lottery-ticket") which had set up a big-screen TV, broadcasting the big Packers-Bears NFL game.  During commercial breaks, the marketing rep would mute the screen and begin a spiel about how "today’s game is brought to you by XYZ Resources; we have millions in cash flow, hot properties, and you need to buy our stock" — though better-finessed than my paraphrase.  They even had a functioning popcorn-maker to feed the crowd.  Pure genius.  Pity his company has a snowball’s chance in hell.  

 

Then there was the fellow I bumped into, wearing a suit; made of brown corduroy.  See, lessons all around!
