Towards a new telecommunications industry quality standard

Article Abstract:

Quality technologies developed by Bell Communications Research (Bellcore) and adopted by Bell Client Companies (BCC) and AT&T are described. The company's philosophy is based on the concept of supplier accountability for product and service quality; companies that supply telecommunications products and services are asked to meet voluntary generic quality requirements. Suppliers are now focusing on quality from the customers' perspective; they link quality with profitability. Quality can suffer, however, when suppliers are driven more by the desire for increased market share or the need to maximize profits by cutting corners in manufacturing. Buyers thus continue to play an important role in guaranteeing the quality of products and services; many large buyers require that suppliers demonstrate an ongoing commitment to quality. The evolution of quality assurance and the Bellcore quality program are described.

Improving software maintenance by learning from the past: a case study

Article Abstract:

Several ways in which software maintenance can be improved through learning from past experience are determined and exemplified by a case study of the Johns Hopkins Oncology Clinical Information System (OCIS). The evolution of large-scale interactive information systems is often an integration of new technologies with existing components or products and a consequence of ongoing software maintenance strategies. Four ways of learning from the past for improved software maintenance are: using development and maintenance experience to improve understanding of the problem, determine what past activities provide the most beneficial maintenance strategies, organizing the product to facilitate comprehension, and examining historic data to affirm equivalence to perceptions.
