When faced with a complex engineering problem, the best strategy usually involves A - Breaking the problem down into smaller problems and solving them individually. B - coming up with a set of very general design criteria to guide development of a solution C - working on the part of the problem that can be solved in the shortest amount of time. D - focusing on solving one part of the problem and working on the rest as time permits.

When faced with a complex engineering problem, the best strategy usually involves( A ) Breaking the problem down into smaller problems and solving them individually.

Explanation:

Th first step of solving a complex problem involves problem identification-it means what exactly is the problem then we try to determine the possible sub-groups in which the problem can be further divided  and then numbering the sub groups.

The process of sub-grouping means that we are sub dividing the problems and then working upon the problem that needs the attention first and then according solving the other sub categories of the problem.

This method helps in breaking the complex problem into a series of small task that can be easily solved in a sequential manner .Thus the complexity of the problem gets reduced when it is divided into a number of small problems.
