Hello Everyone!

Hope you are all doing well. I’m excited to announce that this month's AskE14 question is: What is the worst mistake or problem you've encountered during a project, and what did you learn from it?

Sharing your experiences can help others identify similar challenges and understand how to overcome them. I hope this discussion will be beneficial for those who are just starting out on a project or feeling stuck with a problem.

Here's the question:

  • I had to select a power connector for a product, which had to be different from an existing one to make sure nobody could ever put in a wrong one. 

    So I used a 3.5mm headphone plug (the mono single channel version), which had tip and sleeve only. Functionality was no a problem, it worked flawlessly. The problem was that unit was mounted with the connector hanging off the bottom of the housing most of the time. The cable was too heavy for the retaining force and the plug slipped out all the time. The product had passed CE/FCC certification already, so there was no cheap way to change the style of connector. Duct-tape and hot-glue for the fix (there was no win anymore) during installation. Nobody was happy (customer, service techs, management and myself). 

    Lesson learned: It is never too early to think about usability and user experience (which are 2 separate things) of every interface of a product during development. Best, make it part of the requirements list, to be sure that those considerations make it into the test plan.
