Metrics is defined as the measurement to determine the degree of the conformance to the specifications. This measurement allows the organisation to improve the software process which will help to plan, track and control the software project and also assess the quality of the software which will be produced. It is measurement of such specific attributes of the process, project and product which is used to assess the software metrics. The metrics are measured which give a dashboard to the management on the overall strength of the process, the project and the product. The requirements, specifications, the assurance activities and the metrics are closely looped and linked together. For example, for a customer care service if the requirement is the response to the telephone customer service, the measure of this is to attend 99 percent of the hotline calls within one ring, Assurance activity which is the action to be taken is determining the percentage of calls answered on the ring during the forty-eight-hour period and the Metric is the percentage of the calls to be answered on one ring.
