Logistics and freight management are a fast paced world. There are a lot of factors in your supply chain to consider in order for it to stay optimized and healthy? So how does one keep up with all the tasks so there are tangible returns on investments from the activities around these complex industries? Often, The Pareto Principle is used as a way to get complex projects done. It’s often called the “80/20” rule. Here is another great guest blog post from Chuck Intrieri, whom you can connect with on LinkedIn.
Originally, the Pareto Principle referred to the observation that 80% of Italy’s wealth belonged to only 20% of the population.
More generally, the Pareto Principle is the observation (not law) that most things in life are not distributed evenly. It can mean all of the following things:
But be careful when using this idea! First, there’s a common misconception that the numbers 20 and 80 must add to 100 — they don’t!
20% of the workers could create 10% of the result. Or 50%. Or 80%. Or 99%, or even 100%. Think about it — in a group of 100 workers, 20 could do all the work while the other 80 goof off. In that case, 20% of the workers did 100% of the work. Remember that the 80/20 rule is a rough guide about typical distributions.
Also recognize that the numbers don’t have to be “20%” and “80%” exactly. The key point is that most things in life (effort, reward, and output) are not distributed evenly – some contribute more than others.
What does it mean when we say “things aren’t distributed evenly”? The key point is that each unit of work (or time) doesn’t contribute the same amount.
In a perfect world, every employee would contribute the same amount, every bug would be equally important, every feature would be equally loved by users. Planning would be so easy.
But that isn’t always the case:
The 80/20 rule observes that most things have an unequal distribution. Out of 5 things, perhaps 1 will be a good thing. That good thing/idea/person will result in majority of the impact of the group (the green line). We’d like life to be like the red line, where every piece contributes equally, but that doesn’t always happen.
Of course, this ratio can change. It could be 80/20, 90/10, or 90/20 (remember, the numbers don’t have to add to 100!).
The key point is that most things are not 1/1, where each unit of “input” (effort, time, labor) contributes exactly the same amount of output.
The Pareto Principle helps you realize that the majority of results come from a minority of inputs. Knowing this, if…
20% of workers contribute 80% of results: Focus on rewarding these employees.
20% of bugs contribute 80% of crashes: Focus on fixing these bugs first.
20% of customers contribute 80% of revenue: Focus on satisfying these customers.
The examples go on. The point is to realize that you can often focus your effort on the 20% that makes a difference, instead of the 80% that doesn’t add much.
In economics terms, there is diminishing marginal benefit. This is related to the law of diminishing returns: each additional hour of effort, each extra worker is adding less “oomph” to the final result. By the end, you are spending lots of time on the minor details.
The point is to put in the amount of effort needed to get the most bang for your buck — it’s usually in the first 20% (or 10%, or 30% — the exact amount can vary). In the planning stage, it may be better to get 5 fast prototypes rather than 1 polished product.
This may not be the best strategy in every case. The point of the Pareto principle is to recognize that most things in life are not distributed evenly. Make decisions on allocating time, resources and effort based on this:
These techniques may or may not make sense – the point is to realize you have the option to focus on the important 20%.
Lastly, don’t think the Pareto Principle means only do 80% of the work needed. It may be true that 80% of a bridge is built in the first 20% of the time, but you still need the rest of the bridge in order for it to work. It may be true that 80% of the Mona Lisa was painted in the first 20% of the time, but it wouldn’t be the masterpiece it is without all the details. The Pareto Principle is an observation, not a law of nature.
When you are seeking top quality, you need all 100%. When you are trying to optimize your bang for the buck, focusing on the critical 20% is a time-saver. See what activities generate the most results and give them your appropriate attention.
Simple Example: I use this principle every day. It sets all my priorities, so I’m not “spinning my wheels” knowing what to do next. When I scan my e-mails, I only look for those 20% that are 80% of all e-mails I receive, and concentrate on those e-mails first.
This 80/20 principle can be used by any one for anything in any type of business or personal endeavor.
