An engineering design process is a process used by engineers to help develop products. The engineering design is defined as^{[citation needed]}

… the process of servicing a system, component or process to meet desired deeds. It is a decision-making process (often iterative), in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation.

This process can be divided up into a multi-step process.

Problem definition

Research

A significant amount of time is spent on research, locating, applying, and transferring information ^[1]. Consideration should be given to the existing applicable literature, problems and successes associated with existing solutions, costs, and marketplace needs^[1].

The source of information should be relevant, including existing solutions. Reverse engineering can be an effective technique if other solutions are available on the market ^[1]. Other sources of information include the Internet, local libraries, available government documents, personal organizations, trade journals, vendor catalogs and individual experts available ^[1].

Customer criteria

Criteria, or characteristics desired by the customer should be established from experience, research, market studies, and customer surveys. Solutions are compared on a qualitative basis such as appearance, durability and cost, which are prioritized.

Alternative solutions

The pros and cons of each solution are discussed, including “Brainstorming”.

Analyzing possible solutions

Alternative solutions are analyzed to determine their potential, with the possible solutions condensed. Using basic engineering principles, potential performance of the solution is determined to be physically possibleand economically practical.

Making a decision

Some decisions are easily made through analyzing and constraining from the previous steps, but at other times the decision on which solution to choose is difficult, including the trade offs of one solution over the other. Katherine Ash

Presenting the product

Details about the product can be given visually through sketches.

Communicating and selling the product

Often a written report is produced, or an oral presentation is made.
