The purpose of the instrumentation for the control of production processes is to obtain a quality product, but… What is quality? How do we define it?

According to the Japanese Industrial Standards (JIS), quality is the “totality of own characteristics or performances which are assessed to determine whether or not a product or service satisfies the purposes of its use”.

According to American Society for Quality Control (ASQC), quality is the “totality of functions or characteristics of a product or service aimed at its ability to meet the needs of a certain user”.

According to International Standards Organization (ISO), quality is “the set of properties or characteristics of a product or service which give it the ability to satisfy expressed or implied needs”.

Thus, we see that although quality can be defined on the basis of different concepts (consumer acceptability, social benefit it produces, respect for standards, etc.), large quality organisations prefer to focus on fitness for use.

Quality is fitness for use and we will say that a product has quality or not insofar as its use leaves the user satisfied or not, that is to say, a certain product has quality if the expectations that the user had put in it when he acquired it to give it a specific use have been met.

From this last definition we deduce that judgment in relation to quality is a multivariate and subjective analysis.

It is multivariate because there are many variables that influence the judgment of quality, there are as many as the user wants. And it is subjective because each user chooses the variables they want and gives each one of them a relative weight. There will be users who will attach great importance to product stability over time and others for whom the most important variable will be respect for sustainability during manufacturing.

It is important to point out that when we speak of user we refer to the person who buys the product for whatever purpose: to sell, consume, transform and distribute it. Thus, the same product can have different types of users. A good example to showcase is milk for babies. Who is the user? The baby who takes it (but not buys it), the baby’s parents buy it for the well-being of their baby), the gentleman who takes care of the sale (whether pharmaceutical or large surface area requires conditions that facilitate its storage, a certain useful life, a certain delivery time) and even the Administration (which requires the presence and veracity of the information on the label, the absence of certain contaminants, etc.).

 

Gometrics is especially sensitive to quality and continuous improvement. He currently owns three different certifications , certification ISO9001:2015, Notification of Quality Assurance of Equipment Production for use in Potentially Explosive Atmospheres (ATEX) and accreditation UNE-EN ISO 17025 for pressure, temperature and humidity.
