CONTINOUS IMPROVEMENT

PART I

Eng. Naty Romero Alarcón

Continuos improvement

In the companies are involved in this revolution, the

process of continuous improvement has two

components:

a) Philosophy.

b) Graphical techniques to solve problems

Philosophy

There are common points in the operative

philosophies in these companies which are the

following:

- The quality improvement obtained with the

elimination of the problems causes in the system

inevitably leads to improve the productivity.

- The person in charge of a work is the one who has

major knowledge about it.

Philosophy

Everybody wishes to feel like an important

contributor.

In order to improve a system, its better to work in

equipment than to work individually

The graphical techniques for the solution of

problems allow one to be located, to know where

we can find variations, the relative importance

about to solved problems and if the changes have

had the impact we need.

QUALITY TOOLS

The 7 classic – old tools:

Ishikawa diagram

Pareto chart

Check sheet

Control chart

Flowchart

Histogram

Scatter diagram

ISHIKAWA DIAGRAM

Use it, when it needs to explore and to show all the

possible causes of a problem or a specific condition.

Pareto chart

Use it when it needs to show the relative importance

of all the problems or conditions in order to select

the point of beginning for the solution of problems

or the identification of the fundamental cause of a

problem.

Check sheet

Use it when it needs to collect data, based on the

samples observation with the purpose to detect

tendencies. This it is the logical point of beginning in

the majority of the cycles of problems solution.

Control Chart

Use it when it needs to know if the variability of a

process is because of random causes or if it must to

assignable causes in order to determine if the

process its under control (statistically).

Flowchart

Use it when it

needs to identify

the present and

ideal trajectory

that follows a

product or service

with the purpose

to identify

deviations

HISTOGRAM

Use it when it needs to discover and to show the

distribution of data drawing with bars the number

of units in each category.

Scatter diagram

Use it when it needs to show what it happens with a

variable when another one changes, in order to

prove the theory that the two variables are related.
