Simultaneous engineering - (SE) regular approach to the integrated concurrent product design and their related processes, including support and manufacturing. It appears to be synonymous with Integrated Product Development (IPD) and Concurrent Engineering (CE) [1].

The main objective of simultaneous engineering is to increase design efficiency and also to improve the quality of the process design [2].

Simultaneous engineering is directly related to Design for Manufacturing (DFM) [3].

Main role of SE

Simultaneous engineering plays a major role in engineering/ design. Starting with the expected function of the products, engineers and designers must visualize all of the different scenarios that the product could be utilized [4].

The benefits of simultaneous engineering include increased product quality, reduce time-to-market and lower product costs [5].

Simultaneous engineering allows the following benefits to be achieved [6]:

  • Reduction of cost in the development of new products
  • Better quality of new products as per customer needs
  • Reduction of time for the development of new products

Through SE, one can make the product concept changes in the initial development process steps.

SE the same as CE

The difference between simultaneous and concurrent engineering is more or less important. Due to their relationship and the similarity between methods, CE and SE will be known under one term, which is Concurrent Simultaneous Engineering (CSE) [7].

Simultaneous engineering (known as concurrent engineering) offers powerful and effective methodology for realizing the most satisfying product designs possible from an integrated and global viewpoint [8].
