A set of steps engineers follow to solve a challenge is called an engineering process. It is highly iterative, and elements of the process could be repeated several times in the course of a single project. The exact framing and articulation of the steps repeated will differ.
Research is the first step. This involves identifying the needs, finding information and analyzing constraints. It is an essential part of the engineering design process, because it helps engineers determine the best solution to an issue.
After the researchers have gathered enough data they can begin to brainstorm solutions to the issue. This can be done in a number of ways, and is where engineering creativity really thrives. This is also where ideas are analysed and evaluated. This could involve simulation studies, developing decision matrixes, or even making prototypes to test.
This is the process of students selecting one of their most creative ideas, and developing a plan for its creation. The students then build the prototype using the materials specified and then test the prototype http://emjay-eng.com/steps-of-the-engineering-design-process to ensure that it meets their requirements for performance. Students may have to test and revise their prototype to ensure that it works according to the specifications.
This is a great method to teach about the importance of problem solving and iteration. Engineers are known to design an idea, test the solution and then discover a new issue. The process is repeated until the engineer has an answer that meets their expectations.
