As it can Concurrent engineering vs traditional sequential methods seen, there are huge time savings when concurrent engineering is implemented in the design-to-manufacturing cycle of the product realization.
The basic premise for concurrent engineering revolves around two concepts. The concurrent engineering is a non-linear product or project design approach during which all phases of manufacturing operate at the same time - simultaneously.
Giving the designer ownership is claimed to improve the productivity of the employee and quality of the product, based on the assumption that people who are given a sense of gratification and ownership over their work tend to work harder and design a more robust product, as opposed to an employee that is assigned a task with little say in the general process.
Concurrent engineering replaces the more traditional sequential design flow, or "Waterfall Model". A study claimed that a correct implementation of the concurrent design process can save a significant amount of money, and that organizations have been moving to concurrent design for this reason.
Introduction[ edit ] A publication described concurrent engineering as a new design management system that has matured in recent years to become a well-defined systems approach to optimizing design and engineering cycles.
At any rate the traditional model is vulnerable to a costly and error prone product realization. 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.
The team often consists of product design engineers, manufacturing engineers, marketing personnel, purchasing, finance, and suppliers. After the design team completes its task, the production processes are designed based on the design of the product.
This will result in reducing the overall product cost. Included in this process is taking into full account funding, workforce capability, and time requirements. Only if the estimated cost is lower or equal to the targeted cost, the production of the product can begin. Service providers exist that specialize in this field, not only training people how to perform concurrent design effectively, but also providing the tools to enhance the communication between the team members.
Traditional "Waterfall" or Sequential Development Method vs. This includes establishing user requirements, propagating early conceptual designs, running computational models, creating physical prototypes, and eventually manufacturing the product. This means that info found out later in the process can be added to earlier parts, improving them, and also saving a lot of time.
Beginning in the early s, CE was also adapted for use in the information and content automation field, providing a basis for organization and management of projects outside the physical product development sector for which it was originally designed.
The concurrent or iterative design process encourages prompt changes of tack, so that all aspects of the life cycle of the product are taken into account, allowing for a more evolutionary approach to design.
In concurrent engineering, different tasks are tackled at the same time, and not necessarily in the usual order. Iterative Development Method in concurrent engineering.
Incremental information sharing[ edit ] Incremental information sharing helps minimize the chance that concurrent product realization will lead to surprises. After it is completed it is left alone and everything is concentrated on the next task.
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.
Cross-functional teams are important to the effective sharing of information in a timely fashion. By locating and fixing these issues early, the design team can avoid what often become costly errors as the project moves to more complicated computational models and eventually into the actual manufacturing of hardware.
A frequently asked question is, how good the design can be without involvment of domain experts? A significant part of the concurrent design method is that the individual engineer is given much more say in the overall design process due to the collaborative nature of concurrent engineering.
The different steps are done one after another, with all attention and resources focused on that one task. Figure 5 shows that while the CE design method begins with a cost target for the product, the traditional method has no such benchmark. 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.
In the traditional modelonce 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. Integrated project management[ edit ] Integrated project management ensures that someone is responsible for the entire project, and that responsibility is not abdicated once one aspect of the work is done.
Product and process are closely coordinated to achieve optimal matching of requirements for effective cost, quality, and delivery.
Cross-functional teams[ edit ] Cross-functional teams include people from different area of the workplace that are all involved in a particular process, including manufacturing, hardware and software design, marketing, and so forth.APPLICATION OF CONCURRENT ENGINEERING METHODS TO THE DESIGN OF AN AUTONOMOUS AERIAL ROBOT A THESIS Presented to The Academic Faculty LAcce An Example of the Sequential Design Process 14 The Paradox of Sequential Design' 14 Impact of Concurrent Engineering Application Traditional Engineering Concurrent Engineering everyone works together.
Where as Traditional Engineering each section of the design process is giving to one person and once they complete there section only then can the next person begin working. Deciding between Sequential and Concurrent Tasks in Engineering Design Prasad, Biren, Concurrent Engineering Fundamentals: Integrated Product and Process Organization, Prentice Hall, Deciding between Sequential and Concurrent Tasks in Engineering Design.
In order to signify the differences between the traditional approach of sequential engineering and the modern concurrent engineering approach. A comparison of the concurrent engineering model and the traditional model of product realization is shown in Figure polkadottrail.com it can be seen, there are huge time savings when concurrent engineering is implemented in the design-to-manufacturing cycle of.
Traditional "Waterfall" or Sequential Development Method vs. Iterative Development Method in concurrent engineering.
