With planning, the integrated supply chain can overcome the negative impacts.

It’s a small world after all, the saying goes. Ain’t that the truth!

For decades those of us in the electronics industry, and particularly those closely involved in the technology, have experienced the many changes and benefits a truly global economy can create and offer. Time was, an ocean, time zone or culture may have made integrated product development and manufacturing difficult and costly, if not totally impossible to achieve. Those days are long gone. And yet today it’s the norm that global companies – or consortia– work almost seamlessly together to bring to market the next cutting-edge, technology-rich, and most of all, cost-effective “must have” new product.

The evolution of the global supply chain involved many phases. First, parts, components, supplies and raw materials could be made in locations that offered either the lowest cost or the most advantageous transportation/distribution alternatives, or be where either the raw materials or end-customers were located – all of which resulted in the most cost-effective value. The evolution continued where R&D began taking place in different parts of the globe, which enabled different cultures and engineers in different end-user markets to incorporate the features, benefits and attributes sought by those different demographics into basic design. That led to a reduction of engineering costs to modify newly developed products to become truly universally successful. In turn, people from all over the world with different cultural backgrounds, different economic statuses and different educational levels began to work together and become friends. When people get to know each other, learn to appreciate and trust each other, and share common dreams and goals, the world truly seems smaller.

One measures the variability of process outputs. The other assesses the tests themselves.

People often confuse measurement system analyses and capability studies. Far too often, I hear, “When will we run the capability study on the tester?” And while I’m sure those few brave souls who read my column do not fall into this trap, you might know of people who do. Maybe this column will help.

MSAs are for tests and gages. Capability studies are for the processes being measured. Or, to state it another way, MSAs give us confidence we can measure the capability of our process to produce parts to our customer’s specification.

One can talk about the “capability” of a tester, but only when the word is being used in its classic sense,  for instance, “the extent of someone’s or something’s ability.” Let’s review.

Have you looked at the H.R. 5515, better known as the National Defense Authorization Act for Fiscal Year 2019? 

At the highest magnifications, the differences between the two types of targets become clear.
