Answer:
Approaching a problem and finding a solution within given guidelines.
Step-by-step explanation:
To be a good engineer, you simply need to know how to create a solution to a problem with a given set of restraints or guidelines.
For instance, let's say your boss wants you to build a machine that can automate some trivial task so he can use the worker elsewhere. He wants the machine to be low maintenance and under $40,000.
As an engineer, your first thought should be, let's see what this "trivial task" is, and then after your observation, you should begin to pull upon your experience and resources to build a solution that can be low maintenance and under $40,000.
Put simply, when you approach a problem, consider all aspects of the problem and then build a solution that satisfies all requirements.
Cheers.
