Mistakes to avoid with a first prototype
Most mistakes with a first prototype aren't technical, they're about mismatched expectations.
Expecting a first prototype to already be perfect
The most common mistake is expecting the first prototype to already be close to the final product, with a polished finish and no flaws. This expectation often leads to unjustified disappointment, when a prototype revealing points to adjust is doing exactly its job.
Neglecting real testing conditions
Testing a prototype only under ideal conditions, without reproducing real-use stresses (temperature, handling, frequency of use), gives a false sense of validation. Flaws that only appear under real use are often the most costly to fix once discovered too late.
Frequently asked questions
Is an imperfect first prototype a failure?
No, it's the expected outcome: every flaw identified at this stage avoids a costlier problem later.
Should the prototype be tested in extreme conditions?
It's useful to test it at least under the intended real conditions of use, not just an ideal environment.
