As luck would have it, we at TalentedApps are bestowed with our own personal book reader and recommender. I recently utilized Mark’s services again when he recommended Back of the Napkin by Dan Roam. Back of the Napkin is the latest in my series of obsessed-with-the-visual (Presentation Zen and Slideology being the first two), likely sparked by Meg’s passion about presentations.
Back of the Napkin’s mission is to enable people to solve any problem through pictures. In doing so, Dan lays out a toolkit of sketches for different purposes. Specifically, he identifies the kind of sketch you need to answer the key questions of life – who? what? how much? where? when? how? why?
It occurred to me while reading this book, that Ken had it going on when he challenged the usefulness of the bell curve when making critical business decisions around talent. Adding to Ken’s sound personal and professionally researched case, I now bring forth picture evidence. The fact of the matter is that a bell curve is answering the wrong question.
Before getting into the question being asked, let’s reflect on the questions you could ask and the visual representation needed to answer them:
- Who? – Portrait
- How much? – Bar graph
- Where? – Org chart (map)
- When? – Timeline
- How? – Flowchart
- Why? – Multi-variable plot
The bell curve is a bar chart and the question it answers is “how much?” It answers the most basic question of how many people there are in each performance category and whether there are more in one category than another. Excellent, ready to run your business based on that information? Of course not. Though answering “how many” is a useful starting point, it is not providing real insight. Businesses and talent, in particular, are far more complicated than that.
What you really want to ask is “why?” “Why is region x performing better than region y?” “Why are we losing top talent?” “Why is Raj better suited for promotion than Tina?” In fact, there is an endless supply of why questions when it comes to talent and increasing business performance. Fortunately, there is a visual representation that answers “why?” It is the multi-variable plot.
Here is Dan’s advice when it comes to drawing a Multi-variable plot (you can learn more from Dan’s blog):
Begin with a simple x-y plot, using any two qualitative variables for which you have data as the two coordinates … plot in any quantitative variable for which you have data using appropriately sized bubbles in the middle.
Once that is set, he recommends adding and exchanging different dimensions and/or a timescale to answer particular questions or to draw out hidden insights.
So, there you have it: a picture is worth a thousand words. And in this case, the 9 box or the multi-variable plot is worth a thousand questions from the CEO.
