I shape industrial component trays around the complete task, the people using the arrangement and the development capacity we can responsibly commit.
The arithmetic behind a product promise can be simple enough that nobody checks it carefully. I learned that when a tray described as supporting six jobs held enough of one component for six and enough of the other for three. The drawing was tidy and the larger compartment looked generous. I had approved the proposition without following the complete kit through the customer's defined task.
A full compartment is not a complete job. A clear layout can become ambiguous when the tray arrives from another direction. A customer's long wish list is not yet a funded product range. I want the product decision to follow the whole task and the obligations created by our promise.
