Serial Engineering:
Serial Engineering is characterized by deparments supplying information to design only after a product has been designed, verified and prototyped. In serial engineering the various functions such as design, manufacturing and costumer service are seperated. The information serial engineering flows in succession from phase to phase. For example, prototype model, verified by either simulation or hardware prototyping or both is reviewed for manufacturing, quailty and service.

Prevention Cost:
There is an old adage that an ounce of prevention is worth a pound of cure. The prevention philosophy is essentially concerned with making the product right the first time so that the product performs well during its intended period of use. Accordingly, prevention cost include all the efforts that go into designing and manufacturing a product that meets customer requirements by preventing nonconformance. The elements of such prevention cost include activites involving quality planing and engineering, new product reviews, product and process design, process control, training and quality data acquisiton and analysis.

Change Manangement:
Changes in enterprises result from strategic and operational decisions such as continuous improvement, changes in product designs, changes in product volumes and evolving business processes. Decisions must be made about how to deal with each change. Such decision making may involve many individuals in an enterprise. Once decisions have been made, the impact of the change must be communicated to all those affected in the enterprise. Tools and technologies for group decisions making and communication among employees, customers and suppliers will be invaluablefor achieving sch group process.

Analytical Solid Modeling
In analytical solid modeling, the tensor product method that is used to represent surfaces is extended to three-dimensional parametric space with parameters, say, s, t and u. This is similar to representing a curve by one-dimensional parametric space with one parameter and the surface by two-dimensional parametric space with two parameters. The techniques for creating spline or patch curve segment or surface patches are valid in ASM. As in surface represantion, a general solid describe by x, y and z in Cartesian space is mapped into three-dimensional parametric space via the tensor product formulation.
