Engineering Design & the concept of Risk Assessment
"Design under constraint", as Pfatteicher sums it up. There are many constraints put on an engineer, they are held at utmost standard and are expected to be unique, efficient and creative while still staying within budget, and are confined by physical and legal constraints. Engineers will always strive for perfection and through trial and error, they'll get closer with every mistake.
Prior to any design to come to fruition there are 5 main phases (slide 5/27):
- Analyzing the need
- Creating specifications
- Generating concepts
- Selecting a concept
- Prototyping and manufacturing
Even if the engineer strives for perfection and is extremely heedful, following these steps over and over again; there are so many things that can make it all go south. That's where the concept of Risk assessment comes into play.
Rather than jumping in blindly into a new design, there is a formula that engineers follow in order to assess the potential risk.
There are so many risk factors, that if it were not for this lecture it would have never even crossed my mind to consider; such as intentional harm or terrorism. It gives us an insight into how bright the individuals who design really are, and also how much more we have yet to learn.
