You're having difficulties with a precision component for a critical medical device. The part won't fit the assembly. Or the finish isn't right. Or the quality/consistency is hit and miss. Or any number of other issues. But your existing supplier – who perhaps has been reliable up until now – is pushing back: they did "exactly as instructed", they protest. They followed your drawings/CAD models "to the letter". So what went wrong? And how can it be fixed quickly and cost-effectively? You want a second opinion – is the issue with the supplier, the drawings or both?

You love the brushed aluminium finish on your top-of-the-range designer laptop. And you want the same finish for the high-end medical device you're specifying. But this may not be as easy as you think. The aluminium grade you want may not be readily available. Or the finishing may require special techniques.
