HRO, THE ACRONYM FOR HIGH RELIABILITY ORGANIZATION, IS THE NEXT IN A long line of acronyms that have come into the world of data processing in an attempt to improve the reliability, the availability, and the serviceability (also known as RAS) of the data processing environment. Since I started working with computers in the early 1970s I've heard about or been involved with RAS, TQM, CI, CQI, Six Sigma, Lean Six Sigma, ITIL, PBR, and now HRO. What HRO is and why you should care will be explained shortly. Will HRO, or indeed any of these process models, improve the availability and reliability of our information technology infrastructure?
