The first step is an analysis of the testing requirements for deployment of ATM equipment and services. The activities of ATM test technicians are quite different from those in a research laboratory. In system deployment testing, the fundamental precept is that the system should work as installed. With new ATM technology, there is an area of uncertainty about product behavior. The field deployment sector has a specific set of functions to perform.
Deployment testing is primarily a methodology to isolate and correct faults.
This same percentage will probably also apply to the time to solve these problems. During the early deployment phases, product manufacturers will be obliged to expend a large effort on product support to demonstrate that their products are performing as specified. This effort will also include adequate training service technicians and system users new to ATM technology. In new ATM technology, there are many issues, including conformance and interoperability, that will not have been fully explored during the production phase. This will make it difficult to identify defective components within large complex equipment such as ATM switches.
