How Much Testing?

Hi Everyone,

First, when someone know that one item or type of product can be sold in large numbers, the design of the product is the most important next step. I make paints and related products for over 50 years. Painters give to the future manufacturer to quality we have to produce to satisfy customers by asking them to tell us: What would be the ideal paint? Sample have to match this desirable quality. The next step is to establish production.

Second, when everything is in place, production starts with its quality control with selection of all raw materials, and don't change them to eliminate variations. Painters established all quality control standards and production needs to meet them as viscosity, colour or tinting strength, fineness of grind, foaming characteristic, and surface defects, etc...

Third, after a certain period of adjustments, when production became routine, to accelerate quality control by reducing the number of control to the essentials, viscosity, tinting strength, and surface defects. It was less than 30 minutes per batch. The production must eliminate all variations with the same raw materials following the written standard operating procedures, and one person makes the batch, blend everything together, fill it, and package it. This way there is one responsible for everything. This way we can eliminate variations in all kinds of production.

Concerning the economics? I and sales departments never have any difficulties to make and add profit to the raw material and production costs and sell it. I think a quality product have all the time a good and profitable selling price.
