What is the ultimate goal of successful technical training? In a word, achievement. Everything else is secondary.
My first career was in academia, where book-learned knowledge was the key to success. When I moved on to industry, I quickly found out that the boss doesn’t care what you know, the boss cares what you get done. (Fortunately, they were looking for an ex-teacher for the job, so I was able to get quite a bit done.)
Success in technical training, therefore, means that learners must demonstrate achievement — that they can calibrate the device, that they can write the Excel formula, that they can use an array in programming. Then they can get done what the boss wants done.
