1. Design with specified cost and time criteria.

The old rule of “good, fast and cheap” still applies. There always seems to be time for rework or adjustment after meeting that ultra short deadline, but it is better to allow reasonable time in the design stage for review and correction.

2. Make sure your design specifications can be produced using existing technology.

Programs like Solidworks and the availability of rapid prototyping can provide early insight into potential problems that might occur before metal gets cut. Provide the engineering group with full specifications, do not leave anything out. If something is left out here it will cost time and money to fix later in the process.
