You've heard of the phrase "20% of the work gives 80% of the results" and thats the only thing people know of Pareto, an Italian polymath from the 1800s.
But Pareto developed this as a framework to identify problems, and treat them at their source.
The inverse of this is 20% of the problems block 80% of the results.
Check pic related, as an example for coffee service problems or one for a company with undesirable customer service.
As you make one, you're putting this under the Solve Problems board -- so people can see what are the problems within that department, preventing each QUEST from staying ontrack.
Each day (under a daily tracker) if the day, process, department, project, etc is not green (E.g. is off track), then you increase a simple tally mark of what caused it... if its a new root cause, you increase it by one. If a problem has multiple sources, then you also increase those by one.
At the start (or end of the day) a person can just answer "why didn't we hit the goal today" and then log down the reason why with a simple +1 tally mark.
The bar chart is simply what is the % of frequency over the total of 100%, thats it.
This translates to the bar chart, and over time we see that one problem source is the one that is the most frequent (the vital few).
So you solve for that -- and suddenly the bottleneck from that stops, the dosage of the project was effective and solved it, and starts to trend downward as others start to trend upward.
I've been working out of a writing/journaling version of this, I'm not quite tally marking as we go but making daily reflections and writing why, and then I realized that I keep repeating or updating myself that I have this problem and I'm working through it.
But to condense it down, in a single chart, per Quest to say "why did we not post 1X today" -- oh because I took the day off, or I had too many things I otherwise wanted to do, or I wasn't focused, etc can go down deeper to a unified root cause of "lack of discipline"... Suddenly this was a huge 100% of reasons.
It was in that that I told myself, OK now that I'm aware of the problem, I can solve it. That was in December when I Realize that internal pattern, and moved on.
If I had made a Pareto chart, and put it under my personal board, under my Wellness life area under time management, I could have a pareto trying to solve for "time management problems"... and can source why (I use 5 areas of health, wealth, relationships, time, and mental clarity).
This is able to point towards the root causes, so whenever a project manager's GRAFTS project or internal improvement project is done, they can see what is the exact next thing they ought to work on next... as things adapt over time.
This is maybe a 5-10 minute habit -- it is simply making a pareto bar chart.
To build this, you can use a stupid simple spreadsheet (days x root causes) and have it display a bar chart.
