5.Consistency is instrumental in the development of good problem solving habits, skills and communication. This refers to, for example, the repeated use of reliable step-by-step procedures, convenient sign conventions and coordinate systems, meaningful notations and more. Solving similar problems a different way every time is sometimes possible, but it's not very effective in practice or in the early stages of learning.6. Checks are strategies and methods to validate the accuracy of solutions. The most relevant approaches to use depend on the type of problem being solved. Examples include repeating (double-checking) computations, confirming that a final solution satisfies the boundary conditions, verifying that conservation laws are satisfied and so on.7. Collaboration plays an integral role in nearly every phase of engineering. Examples include interdisciplinary teams working on design projects and students in a study group practicing solutions to challenging problems. The success of a team usually depends on the leadership, goal setting, task planning and other teamwork skills of its members.Note that these are not steps for engineering problem solving. Rather, they are the main components or ingredients that are required to solve problems. In most problems, many of the Seven C's will play a role, though perhaps not all of them at once.
