  • Look it up!

Although it is important to learn a lot of information to be an engineer, it is even more important to learn to solve problems. Some of the problems have to include specific rules, measurements, and calculations. In order to work out the solution, engineers rely on very detailed information. The good news is, they don’t have to remember everything! But they do need to know that the information is available, and where to look it up.

For example, if an engineer needs to know what kind of pipe to order to fix a leak in a gas line, there are plenty of resources available in books, catalogs, and even college textbooks. Most engineers rely on web sites like the Engineering Toolbox. This handy reference has “all” the information IF you know what you are looking for. Engineers ask themselves the questions that correspond to the steps in the [/Engineering%20Design%20Process Engineering Design Process] to find the answer.

  • Ask (What? Ask questions, understand the need, identify the problem, define)
    Some things about the problem are known. For example, gas is leaking and that should not be happening.
    Q: What is known about the problem?
  • Imagine (So what? Imagine, brainstorm, explore, discover)
    Sometimes, just looking through a resource like the Engineering Toolbox helps solve the problem. Here are a lot of possible solutions.
    Q: Do any of these solutions fix the problem or one like it?
  • Plan (Now what? Plan, design)
    Finding a general solution may not be enough. A new piece of pipe can fix the problem. There are lots of different types and sizes of pipe to chose from.
    Q: What kind of pipe is required? How big should the pipe be?
  • Create (Do it. Create, try it out)
    After working out all the specifics for the type of pipe and quantity, the item has to be acquired and installed.
    Q: Are special tools needed to install the pipe?
  • Improve (If this then what? Improve, make it better)
    Next time it is easier to look up information. Becoming familiar with the site, navigation, format, help make the job easier.
    How could the information be organized to make it easier to find?
