Traditional engineering, also known as sequential engineering, is the process of marketing, engineering design, manufacturing, testing and production where each stage of the development process is carried out separately, and the next stage cannot start until the previous stage is finished. Therefore the information flow is only in one direction, and it is not until the end of the chain that errors, changes and corrections can be relayed to the start of the sequence, causing estimated costs to be under predicted. This can cause many problems; such as time consumption due to many modifications being made as each stage does not take into account the next. This method is hardly used today, as the concept of concurrent engineering is more efficient.
