What is Your Design Tradeoff Strategy?

Posted November 02, 2011 7:17 AM

Engineers of all disciplines are forced to contemplate trade-offs when seeking a suitable design solution. What has been the hardest design tradeoff you have dealt with?

I am not even going to address safety, thats off the table.

But the trade off always is performance, to meet a slashed budget or schedule

The three criteria:

budget, schedule or quality.

When managing a project. those three, pick (2). there are at times where you take a new approach and the outcome turns out better than the original, at times not.

The key is to keep the stakeholders informed.

Keeping in mind, its not so much about producing a product, it the product performing.

The design problem is formulated with preference rankings, similar to a utility theory or fuzzy sets approach. This approach separates the designtrade-off strategy from the performance expressions.
