Developed by the economist Vilfredo Pareto to explain the concentration of wealth.
PARETO Analysis
PARETO Analysis is developed by
Vilfredo Pareto
Items of interest are identified and measured on a common scale and
then ordered in descending order, creating a cumulative (add.) distribution
Pareto Analysis
Typically, 20 percent of the ranked items account for 80 percent or more of the total activity;
consequently the technique is sometimes called the
80-20 rule
By arranging the bars of a Pareto chart from ________________ can help an analyst to
determine which categories will yield the biggest gains if addressed, and which are
only minor contributors to the problem.
largest to smallest
Sort the problems by frequency or by level of impact.
Pareto Chart
This pattern shows that just a few categories of the
problem account for the most occurrences or impact.
Clear Pareto Effect
This pattern shows that no cause you’ve identified is
more important than any other.
No Pareto Effect
Also known as cause-and-effect diagrams, were developed by Kaoru Ishikawa in the early
1950’s.
Fish Diagrams
He developed Fish Diagrams in the early 1950s.
Kaoru Ishikawa
Sparks creative thinking about the causes of observed problems. The emphasis is on
thinking broadly about what’s going on in the process. Method for pushing people to think
about root causes.
Fish Diagrams
6Ms in Fish Diagrams
1) Environment (Mother Nature)
2) Methods
3) Materials
4) Administrative (Management)
5) Machine
6) Human (Man)
It is probably the first project planning and control technique to emerge
during the 1940s in response to the need to manage complex defense projects and
systems better.
Gantt Chart
Simply shows the anticipated completion times for various project activities as
bars plotted against time on the horizontal axis.
Gantt Chart
It can also be utilized for sequencing machine activity on the plant floor. The
machine-based chart can include repair or maintenance activity by crossing out the time
period in which the planned downtime will occur.
Gantt Chart
Identifies problems within a particular area, department, or
worksite. Before collecting quantitative data, the analyst first walks through the area and
observes the worker, the task, the workplace, and the surrounding working environment.
Job/Worksite Analysis
PERT chart stands for
Program Evaluation and Review Technique
PERT Chart is also pertained to as the
network diagram or critical path method
A planning and control tool that
graphically portrays the optimum way to attain some predetermined objective, generally in
terms of time
PERT Chart
This implies that when the intent is to reduce the project completion time, termed _____________, it is
better to concentrate on activities that lie on the critical path than on those on other pathways.
crashing
The minimum time needed to complete the entire project corresponds to the longest path from the
initial node to the final node. Termed the _____________.
Critical Path
In Pareto analysis, items of interest
are identified and measured on a
common scale and then ordered in
_____________ order, creating a
cumulative distribution.
descending
