Engineering design is the process of devising a
system, component, or process to meet desired
needs. It is a decision-making process in which
the basic sciences, mathematics, and engineering
sciences are used to convert resources optimally
to meet a stated objective. Engineering design
includes most of the following features
creativity open-ended problems formulation
of design problem statements and
specifications consideration of alternative
solutions feasibility considerations productio
n processes detailed system descriptions const
raints such as economic factors, safety,
reliability, aesthetics, ethics and social
impact. - Adapted  from ABET

• Steps in the engineering design loop (typically
  an iterative process)
• 1. Encounter a problem.
• 2. Formally define the problem.
• 3. Identify criteria for solving the problem.
• 4. Prioritize the desired outcomes to the
  problem.
• 5. Create a list of possible solutions. Each
  possible solution is a plan.
• 6. Create an implementation of the most feasable
  solution.
• 7. Evaluate the effectiveness of the solution.
• Engineering Designers typically follow these
  steps
• 1. Understand their customer's needs
  (requirements).
• Establish design objectives (specifications) to
  satisfy a given set of customer attributes.
• Define the problem they must solve to satisfy
  these needs.
• 3. Create and select the solution through
  synthesis.
• 4. Analyze and optimize the proposed solution
• 5. Check (validate) the resulting design against
  the customer's needs.
