Continous improvement tools
- 1. INTRODUCTION TOOLS CONTINOUS IMPROVEMENT PART I Eng. Naty Romero Alarcón
- 2. 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
- 3. 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.
- 4. 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.
- 5. QUALITY TOOLS The 7 classic – old tools: Ishikawa diagram Pareto chart Check sheet Control chart Flowchart Histogram Scatter diagram
- 6. ISHIKAWA DIAGRAM Use it, when it needs to explore and to show all the possible causes of a problem or a specific condition.
- 7. 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.
- 8. 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.
- 9. 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).
- 10. 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
- 11. 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.
- 12. 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.
