Sr. Bailey et al., PROCESS-CONTROL (ISO-9000) AND PROCESS IMPROVEMENT (APEX) IN THE TRANSMISSION-SYSTEMS BUSINESS UNIT, AT&T technical journal, 73(1), 1994, pp. 17-25
Continuous improvement implies both process control (i.e., standardiza
tion to reduce variation) and process improvement, accompanied by all
of the process changes these imply. This paper describes why and how A
T&T's Transmission Systems Business Unit (TSBU) standardized its proce
sses using International Organization for Standardization (ISO) 9000,
and improved its processes with the APEX (Achieving Process EXcellence
) process management structure.
