Caption: Every time I’m asked to sign a waive/concession approval, I can’t help but feel uneasy. (Boss asks you to approve a concession? How engineers protect themselves from taking the blame.)

Have you ever been in this situation? It’s late at night, you’re working overtime, and suddenly your manager drops a pile of expired components or badly out-of-spec parts on your desk and says, “The customer needs this shipped urgently—just sign a waiver and go home!” Have you ever faced that moment? And after you sign the waiver, if something goes wrong, who actually takes the blame?

Workingbear remembers when he first entered the electronics industry as a junior product or process engineer. The first time colleagues from Quality and Production asked him to “waive” a product, He just froze on the spot. He had no idea what they were talking about—and even got laughed at by the line supervisor.

How Adding a Second Source (2nd Source) Can Create a Win-Win for Cost Reduction

How Adding a Second Source (2nd Source) Can Create a Win-Win for Cost Reduction

As an engineer, Workingbear has to be honest—I really don’t like doing second-source qualification work. It’s time-consuming, stressful, and often thankless. If you do it well, management thinks it’s just part of your job. If it takes too long, they think you’re being difficult on purpose. And if any issue shows up later, they question your ability—“Why didn’t you catch this earlier?”

Explaining the Relationship Between BOM, AML, AVL, and MPN

BOMs, AML/AVL, and MPNs are essentially the “recipe” behind electronics manufacturing. All of these terms are closely related to a product’s material list. Understanding what they mean is not difficult—the real challenge is knowing how to apply them effectively to achieve proper material control within a company.
