Multi-Voting, also known as N/3 multi-voting, N/3 voting, dot-voting and sometimes mistakenly thought to be identical to nominal group technique, is a technique used by small groups to quickly select a subset from a broader set of options. This democratic approach allows team member to cast a finite number of votes, with few restrictions (e.g., individuals can’t “plump” all of their votes on one single candidate), for their options of choice. Ultimately, the process yields a rank order.

Be cautious when there’s some, be cautious when there’s none, and be cautious when adding more than one.

What do the heck does that mean???

Let’s take these correlation cautions one by one.

Be cautious when there’s some. Suppose you did a study and found a correlation between job performance and high school grades. Does this mean that if we simply increase everyone’s high school grades that they will perform better at work???  Clearly not! 

On behalf of Michael O'Connor, Larry Loucka, and myself, I would like to thank you for investing your valuable time this year reading our posts and sometimes sharing your thoughts. We truly appreciate your readership and we hope that we have, in some way, provided assistance in your lean journey.

In that spirit, some basic holiday lean math follows...


We are coming to the end of the year so it is a good time to reflect on where we have been and start thinking about next year. And to make the thinking definite, let’s suppose that you estimate that 85% of your customers will stick with you next year and 10% of your competitor’s customers will switch and become your customers. Is it time to open the champagne and give everyone a big holiday bonus???

And just to make the math easy, let’s just suppose that you presently have 1000 customers and your competitors have a total of 1000 customers as well. 

Heijunka, also known as level-loading, production-leveling or production-smoothing, is a foundational element of the Toyota Production System. It facilitates system stability by addressing workload unevenness (mura) through the leveling of both volume and mix over time, see Figure 1. Heijunka also serves as a pacing mechanism for operations, often reflected in the use of heijunka, leveling, or schedule boxes, which are typically designed using pitch intervals, see separate pitch post.
