Define specific problem to

principle, named after 19thcentury economist Vilfredo Pareto,
suggests that most effects come
from relatively few causes; that is,
80% of the effects come from 20%
of the causes. The Pareto chart is

Pull Scheduling is generally

SMED
(quick changeover)
As lean production is dependent
upon small lot sizes, small lot
sizes are dependent upon quick
changeovers. If set-ups or
changeovers are lengthy, it is
mathematically impossible to run
small lots of parts with low
inventory because large inprocess inventories must be
maintained to feed production
during changeovers.

7 Basic Tools
•
•
The designation arose in postwar Japan, inspired by the seven famous weapons of
Benkei. At that time, companies that had set about training their workforces in
statistical quality control found that the complexity of the subject intimidated the
vast majority of their workers and scaled back training to focus primarily on simpler
methods which suffice for most quality-related issues.
The Seven Basic Tools stand in contrast to more advanced statistical methods such
as survey sampling, acceptance sampling, statistical hypothesis testing, design of
experiments, multivariate analysis, and various methods developed in the field of
operations research.
The seven tools are:
• Cause-and-effect (also known as the "fish-bone" or Ishikawa) diagram
• Check sheet
• Control chart
• Histogram
• Pareto chart
• Scatter diagram
• Stratification (alternately, flow chart or run chart)
