Hi,
What is the best way to explain Pareto principle to an SME and why they should apply it?
It seems like big corporations do not mind any analysis to be completed and they are happy to spend budget. However, when it comes to small or medium company management is more reluctant to deep-dive into such an analysis.
What are your thoughts on that? Did you have a similar experience?
Thanks,
Marieta

decent business analysis is always difficult for SME's
They often don't have the time and it can be difficult to predict the financial benefits in advance. There's also the problem that they may not have the data for such analysis - or at least in a suitable format.
If it's a law firm you could start by asking staff/partners - where does our income come from? ie do we get 80% (or thereabouts) of our income from the top 20% of cases we deal with?
The answer from staff is usually - we've no idea!Â
You could then try some quick analysis on a sample of cases to analyse where the firm's income comes from and the implications of this
You can also factor in staff time spent on such cases and correlate this against income.

Hope that helps

At around the time of WW1 the brave soldier Schwejk observed that
Â
"80% of all the beer is drunk by 20% of all men".
Â
This shouldn't be too difficult to assimilate even for the smallest and least educated business owner?
Â
On a more serious note: define SME? It can be a sole self-employed carpenter, or - at the other end of the spectrum, a business with 50 employees and 10m turnover (the official definition of SME). To make things more complicated, this rather broad range may also vary byÂ
Â
- Customer base: from a consumer business serving thousands of customers, to a B2B firm subcontracted by a bigger one and working for a single client (what Pareto?)
Â
- Industry sector and nature of product/service: small scale manufacturing will differ form a professional services firm (accountants, lawyers)
Â
- Ability to individually identify customers: businesses where they have an account and their identity is known, vs anonymous consumers 'from the street' who you cannot track or 'tag' with a 20% or 80% segment sticker...
Â
I took this long just to illustrate that even a simple 20:80 for a simple SME is not so simple. So the shorter answer (even shorter than the Schwejk joke above, and even more correct) is
Â
It depends.

Best to approach each individual case according to who/what that SME is.

Hi Marieta:
Anyone can use Pareto's Principle.
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, output) are not distributed evenly – some contribute more than others.
Life Isn’t Fair
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 [removed] 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.
So Why Is This Useful?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 a 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.
Concluding Thoughts: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.
The Pareto Principle has many applications in quality control. It is the basis for the Pareto diagram, one of the key tools used in total quality control and Six Sigma.
In PMBOK, Pareto ordering is used to guide corrective action and to help the project team take steps to fix the problems that are causing the greatest number of defects first.

Here is a simple example of a Pareto diagram, using sample data showing the relative frequency of causes for errors on websites. It enables you to see what 20% of cases are causing 80% of the problems and where efforts should be focussed to achieve the greatest improvement. In this case, we can see that broken links, spelling errors and missing title tags should be the focus.
