Defination: A project is a set of task/activities undertaken to create a product, services or results. These are temporary, in the sense that they are not routine work like production activity but most often one time set of activities undertaken.
Example: A project for a product will result in a complete product or part of a product. An example would be the creation of the Microsoft Surprise tablet that used a liquid magnesium deposition process to create the enclosure. The process developed in the project will be used for subsequent production of the tablet. Examples could include development of a new product or process (as in the example), constructing a road or a bridge (infrastructure in general), developing a computer/information system, etc.
