An improved approach to product quality through testing
Due to the crucial importance of the 1B processor project, AT&T Network Systems (NS) implemented extensive testing programs to ensure that the product delivered was of the highest quality and met customers' needs. In addition to normal customer acceptance testing, the AT&T Network Services Division (NSD) introduced an innovative new strategy called the accelerated life-cycle test program (ALTP) to facilitate the identification and repair of defects. NSD used a 4ESS™ switch having 100-percent reversible traffic to test the retrofit process and to ensure that customer service would not be adversely affected by the introduction of the 1B into the AT&T network. This paper describes the final product integration and verification processes performed by NS, along with the special testing programs established by NSD customers.
The objective of the present study is to find out how the use of the Internet is perceived and felt by the students. The sample was made up of 51 students from 4 educational establishments in the VIII, IX and X Regions in Chile. The Coopersmith Self-Esteem Inventory was used in the collection of quantitative data.
