Mechanical engineering design is a highly iterative process make up from different discipline which are working interactively to comply with certain standard to meet certain reliability and other design functions.

Design is a decision-making and iterative processes which involving communication-intensive using oral, graph, drawing, and mathematical languages in order to specified need or problem with typically very little information provided; hence the designer must have skill to innovate. The design must take into account functionality, safety, reliability, competitiveness, usability, manufacturability, and marketability.
