The application of quality control tools It is essential in such a competitive world where a company needs to position itself over another by demonstrating its efficiency.
For this reason it is important that if you have a company regardless of its size that you keep up-to-date information on this type of tools and diagrams that you can use and you need to know how to use them. All this you are about to read below.
What are quality control tools and what are they used for?
- When applying the quality control tools your company obtains many benefits, a high profitability without the need for an increase in costs.
- Even a quality management system that is based on a standard like ISO 9001 ensures that your company will achieve the purpose of continuous improvement in the production process of your product.
- They are tools that are used to determine different parameters, perform an analysis on production and also propose possible solutions to the problems that may arise and that are identified during the analysis.
Quality Control Tools: Flow Chart
The flow diagram is the one that allows to identify the best path that the product should follow in its production cycle, that is, it is followed up step by step and therefore it is much easier to understand the process and also the possibility of submitting a proposal in order to improve this process is made easier.
Quality Control Tools: Ishikawa Diagram
The Ishikawa Diagram is the Fishbone Diagram which is commonly called cause and effect or also fishbone diagram. It is the one that allows to identify what are the causes of a problem with its effects through the relationship between effect and possible causes that may be involved. Use variants such as environment, women, men, measure, material, and method.
From tabulated data, the elimination process that gives rise to the cause with greater probability begins, which leads to the generation of the solution.
Quality Control Tools: Data Table
With a tabulated format, the data table provides systematic and methodical information that makes it easy to review and observe behavioral trends.
Quality Control Tools: Check Sheets
The verification sheets are elements that are evaluated by default and are used as a way of certifying the fulfillment of activities or evaluation of the fulfillment of certain processes.
Quality Control Tools: Pareto Chart
The Pareto Chart is a chart that establishes the order of the causes that caused losses and the way in which they can be repaired. It achieves this by taking data from different sources of information.
Quality control tools: Histograms
Histograms are those that reveal the frequency distribution of the data that you obtain from measurements with a bar graph that indicates the number of units in each category.
Quality Control Tools: Scatter Plot
The scatter diagram is the one that reveals data about one variable from the change of another, and to say that it represents two or more variables organized in a graph and one is modifiable as a function of the other.
Quality control of a company
- The quality control of a company requires the implementation of techniques, tools, mechanisms or programs to improve the quality of production, its services provided or its products.
- Its objective is to satisfy and comply with the objectives of the company from being applied to all the processes carried out by the company.
- It obtains the information on the standards that are expected by the market and from this it exercises control over each procedure until the service or product is developed with its subsequent services such as the distribution of the product.
Advantages of quality control tools
When the quality control tools the company gets many advantages, for example:
- The processes d the company can maintain an order of importance interrelating the same regardless of their difference.
- The company can follow up with all the details of its operations.
- Problems are easier to be detected and at the same time simpler is their correction.
- The company establishes a quality plan from which actions and projects are collected that are aimed at a higher quality of operations and consequently achieves customer satisfaction.
- Quality control goes beyond the quality of the product, it extends to the quality of work, the quality of the production process, the quality of the information, the quality of the workers, the quality of the objectives, to the quality of the company and to quality in terms of compliance with the requirements that are clearly established to avoid problems.
- Continuous measurements are carried out that determine the conformity of these requirements, because if there is no conformity it would mean a lack of quality.
- So when the company meets the requirements, it is meeting what the customer needs by offering a product with minimal defects or errors.
Ishikawa diagram or fish diagram for quality control
- The Ishikawa diagram or fish diagram is a simple graph that shows on the horizontal plane line or central spine that represents the problem to be analyzed. The problem is written on the right.
- It is a causal diagram with the graphic representation of the multiple cause-effect relationships between the variables of a process.
- A causal diagram in the general theory of systems shows in a graph inputs or inputs, the process and the outputs or outputs of a system with their feedback in view of the control subsystem.
- The problem to be analyzed with its horizontal axis reaching oblique lines as if they were spines of a fish are representative of the causes.
- Each line is representative of a possible cause and receives lines parallel to the representative center line of secondary causes.
- It is a tool that, thanks to a participatory analysis of analysis groups, allows the use of techniques such as brainstorming, which makes it easier to obtain an understanding of the cause that originated a problem and its consequent solution.
- In fact, when it comes to brainstorming and problem solving, the Ishikawa diagram is the most useful for the focus of the conversation or when it is necessary to analyze a problem without having a lot of data to help with its resolution.
