Methods of Stating Specifications and Requirements
The specifications and the requirements of the need can be stated in a number of ways, some these are:
1) In general terms: In many cases the specifications of the product to be designed are specified in a very vague manner. Say for instance if the customer wants the company to launch a new product they will just give a vague idea like low power and high mileage for the vehicle. Based on this idea the detailed specifications and the requirements can be worked out at the time of designing.
2) Specification written in great details: The professional people and companies give detailed specifications and requirements of their needs. Some example of the professional companies can be militaries, atomic energy commission, and other sophisticated engineering companies. For instance if the military company gives the order for manufacture of the trucks, they will give detailed specifications of their requirements like the capacity of the truck, the strength required, the size of the engine, the power desired, the load lifting capacity, the safety factors, etc. In these requirements all the design and performance requirements are clearly stated.
The health, safety, or any other legal requirements will be part of the original specifications. In addition to these specifications the government, commercial and industrial standards are made an important parts of the specifications. One of the important points to note is that when the company produces specification, they keep in mind the production competence and the capacity of the company that has to design and manufacture the product.
