Hi, everyone, and today we have an important principle about Berita principles, the secret to success
by achieving more, with less so Breteau principle defenders, that how to find the most important thing
is to do the great success based on these things.
How can 20 percent of effort for making the 80 percent of results?
So it's called 20, 80 percent.
OK, on the other hand, 80 percent of the result is produced by only 20 percent of effort.
OK, so 20 percent of effort producing 80 percent of results.
So the important here, how to find the 20 percent of the effort that forming the 80 percent of results.
This is the question and this is the analysis.
And this is the burrito principle and berita analysis, OK?
So here in this chart, there are many components and we will focus on the 80 percent of this component.
OK, and this is Berita analysis.
There are two types of items, 80 percent items and 20 percent items.
OK, and here is another example.
There are two items, 80 percent items and 20 percent items.
The question is, how can we get the 80 percent items?
Okay, let's take a practical example from Microsoft Excel.
And here is one example of a cost analysis with cost analysis with Berita charts, cost analysis of
Tesla factory in USA in 2021.
And here is a cost center, parties, the material, and here is annual cost and percentage total and
there is a cumulative percent.
And here is manufacture, equipment, salaries, maintenance, office lease, warehouse, lease assurance
benefits and pensions and vehicles research.
And here is the total.
So based on this table, what are the most important cost centers based on that annual cost?
The first thing after entering the data is to order the data.
Disentangling you should calculate the percentage of the total by dividing this value.
On the total value of the of the total value of the cost centers and here is the person and based on
this person's order, this person is descendant from the greatest to smallest.
And after that, calculate the cumulative percentage based on the person of total and search for 80
percent.
And here is the 80 percent.
So the most important cost centers for these items are this yellow shaded items.
Why?
Because these items represent 80 percent of the cumulative percentage and 80 percent of the total cost.
OK, and here is presentation of these data based on the political analysis, a chart.
And here is the different cost items.
And the most important items is the parties and the materials and represents about 31 percent.
And after that, the two items represent 52 percent and so on.
The first items are Bartis and material and manufacturing equipment, salaries, maintenance, and these
are formulating 80 percent of the Berita chart and the cost center.
So the most important part is, are these based on Berita analysis?
And here is that bar chart of each cost center.
And here and here is the quality of care of the cost center.
OK, let's take another example.
And here is another example about NASA NewSat and about the testing and and the problem of engines like
Jet Propulsion Lab engines.
And this time and this time the problem not represented in function, of course, but representatives
of function of occurences.
OK, occurences of a problem.
So the first problem was transmission, failed system, miscellaneous noise drive controls other electrical
ignition, cooling system, braking, emissions steering.
So after entering the occurences data, just calculate that percentage based on each occurrence and
the total number of occurrence after that, calculate the cumulative percentage based on that percent
of total and after that search for 80 percent.
And here is the 80 percent.
So these parties are the most important parts of the problem.
And here are so transmission fail system.
Saturnus noise and driver control and other electrical are the most important causes for the problem
because they are represented about 80 percent for this problem.
And here is the graph representation.
Here is the bar chart for the problem.
And here is that commodity care for this problem and here is 80 percent and you can intersect 80 percent
with with with the items to find that the most important items are intersecting with 80 percent from
here.
So just through an intersection with this curve, with 80 percent to find the most important items here.
OK.
That's about Berita analysis, and that's about the problem analysis with Paretta Excel template.
I hope this lecture to be useful for you.
Thank you.
And see you in the next Tremblant.
