Concurrent engineering
Concurrent engineering is a work methodology based on the parallelization of tasks (i.e. performing tasks concurrently), which is sometimes called Simultaneous Engineering or Integrated Product Development (IPD).It refers to an approach used in product development in which functions of design engineering, manufacturing engineering and other functions are integrated to reduce the elapsed time required to bring a new product to the market. What is Concurrent Engineering? Concurrent engineering, also known as simultaneous engineering, is a method of designing and developing products, in which the different stages run simultaneously, rather than consecutively. It decreases product development time and also the time to market, leading to improved productivity and reduced costs. Concurrent Engineering is a long term business strategy, with long term benefits to business. Though initial implementation can be challenging, the competitive advantage means it is beneficial in the long term. It removes the need to have multiple design reworks, by creating an environment for designing a product right the first time round. In the traditional model, once the design is made, all of the departments that are invilved in the product realization are expected to follow it although they have very little input in the design of the product. A frequently asked question is, how good the design can be without involvment of domain experts? Very often, the design team in the traditional model, do not have the knowledge and the skills to make a product that will be functional, of high quality and manufacturable. After the design team completes its task, the production processes are designed based on the design of the product. Therefore, if the product is poorly designed, the ensuing processes will be poorly designed, too. For example, if the manufacturing department has a part, that is difficult to manufacture due to the poor design, considerable time will be expended in order to manufacture the part. To accomplish this, sometimes, the manufacturing department introduces changes to the original design such as either updating the part tolerances or changing the number of parts in the design. At the same time, the changes in the product design may not be either communicated to others in the product realization process or too late to prevent decisions that are based on the original product design. At any rate the traditional model is vulnerable to a costly and error prone product realization. Figure 5 shows that while the CE design method begins with a cost target for the product, the traditional method has no such benchmark. Following the design stage, the CE team compares the derived cost of the product design to the targeted cost. Only if the estimated cost is lower or equal to the targeted cost, the production of the product can begin. Such design discipline is essential to ensure that the price of the product is competitive in the market. It is obvious that by following the CE model all the disadvantages of the traditional model can be avoided. The difference in the two approaches will be more evident upon study of the overall production cost in the product's life cycle. |
