QA Method

The Pareto diagram is a diagram that displays classified defects or failures in descending order, together with the accumulated values. The chart is useful when examining the failures of defects that most be corrected, in other words, serious problems.

It is very tedious to prepare Pareto Chart manually. It consumes more time if Pareto Chart will be prepared using pencil and paper. You can now download Pareto Chart On Excel for free.

Pareto Chart On Excel can generated in easily in several different project applications. But everyone has no access to this special project application. Fortunately, Pareto Chart On Excel is being used as an analysis tool which can be generated easily using Microsoft Office Excel application.

Pareto Chart On Excel generates your chart in minute. It saves your time and effort. All you have to do is to input the raw data and in just a minute your Pareto Chart On Excel will be generated. So you can easily pinpoint the root cause of the problem shown in Pareto Chart On Excel and establish effective countermeasure to prevent and eliminate the re-occurrence of problem.

You can use Pareto Chart On Excel to present your project in order to have a good visual control to find the true root cause of the problem.

You have to make analysis for the Reject 1, Reject 2, and Reject 3 using Pareto Chart On Excel to find the root cause of the rejects and to established effective countermeasures. If we eliminated these three rejects, 72%
of the rejection rate was reduced.

The first step is to gather your data and arranged the data in descending order. Once all required data was arranged, all you have to do is to input those data in Pareto Chart on Excel and your Pareto Chart On Excel will be graphed automatically in minutes. Once the chart was generated using Pareto Chart On Excel, you have to select the first three problems to analyze. You have to conduct brainstorming and utilized the PDCA (Plan, Do, Check, Act) Cycle to come up with the true root cause of the problem.

Once the true root cause was identified for each three rejects shown in Pareto Chart On Excel, you have to formulate actions and countermeasure through brainstorming. If the appropriate action was decided, it will now be implemented at a decided method, time, person in-charge, and place. Verification will now be done to check if the decided actions are effectively solved the problem as shown in Pareto Chart On Excel. If the actions were not effective, Pareto Chart On Excel will be used again to established a new pareto chart to be used again to analyze the problem. In this stage, PDCA Cycle will be utilized until the problem was totally eliminated.

A Pareto diagram is a diagram categorizing the number of cases of occurrence (or the amount of loss) of nonconformity and number of nonconformity into items and showing them in descending order. We can find out which item has the problem and how much the impact has spread for the detected defects. There are seven steps to make a pareto chart. There are also different fators or items to be considered to make a Pareto chart

The following steps are guidelines to make a pareto chart:

1. Determine the necessary fields or items.
a. Items relating to the results of defects - type and location of defect, date/period, shift, type of product, etc.
b. Items relating to causes - raw material, components, method of manufacturing, worker, machinery, equipment, etc.)

2. Define a period for data collection.
a. Record the conditions/fields in detail (this information can be used for other tests.
b. Make and use a check sheet for recording data.

3. Fill in the data table.
a. Organize the data according to the type of item (defect) and arrance the items in descending order.
b. calculate the accumulated number, ratio and accumulated ratio, as well as totals.

4. The X represents the type of item and the Y axis the number of defects (failures).
a. Make a scale and the unit of measure for the data on the Y axis.
b. Arrange the items (defect) on the X axis so that the length of X axis approximately equals that of the Y axis.

5. Make a bar and line graph.
a. The bar graph represents the type of defect, and the line graph (called a Pareto curve) represents the accumulated ratio (%).
b. Arrange the type of defects in descending order from left. Place "Others" at the far right.

6. Make a scale for the accumulated ration on the Y axis.
a. Set the maximum level (100%) of the accumulated ratio equal to the sum of defects (failures).

7. Write necessary information into the Pareto Diagram.
a. Also write information about who, when, and for what purpose the Pareto Diagram was created.

Note: Write other information such as the number of data, purpose, period used for data collection, date of creation, name of person who recorded the data.

Through Pareto diagram, it can be identified which types of defects are dominant, select targets for improvement, narrow down the targets, identify the results of improvement, Pareto diagram can be more useful for the analysis than the review of results, and understand the nature and pattern of problems.

QA Method provides you latest quality tools, methods, and techniques to manage quality assurance system in order to obtain the optimum result to win customer satisfaction. In manufacturing processes, it is very important to control the quality of a product in order to satisfy the requirements of customers using QA Method.

QA Method is very important tool to assure that the production processes are conforming with the requirements to produce a quality products that win customer satisfaction. QA Method is a technique involves in quality assurance and management system to control the quality in processes and the product itself.

QA Method is applied to control the quality starting from the receipt of raw materials, incoming quality inspection, production, outgoing inspection, storage of finished goods, until the delivery of products. QA Method is also applied to analyze quality abnormality and established concrete countermeasures to prevent the re-occurrence of problem.

Raw materials should undergo incoming inspection to verify if the materials that we are going to use to produce a product will satisfy the quality requirement. QA Method is used to inspect the appearance characteristics, dimensional requirements, and environment-related chemical substances requirements of raw materials prior to the issuance to production process.

During production operation, processes should be controlled in order to built quality into a product. QA Method is also being used to eliminate quality abnormality during mass production. QA Method should be utilized in order to improve the quality level of production through introduction of new QA System in order to achieved the productivity and quality targets.

After the products have been produced, QA Method should be utilized during outgoing inspection to checked if the products were produced according to requirements of customer. Appearance characteristics, dimensional requirements, and chemical content specification is being verified if the product conform with the customer requirements. If all requirements have been satisfied, the product will now be delivered to customer.

If quality abnormality was occurred, QA Method is also used in order to analyze root cause of the problem to established effective countermeasure to prevent its re-occurrence. Regular verification of action if it is continuously implemented is also done through QA Method.

QA Method is also being applied to improve quality level of the company. Quality improvement plan should be established in order to have a detailed activity to be implemented to reduced quality rejects, eliminate production wastes, and increase profit of the company through maximization of available resources using QA Method.
