High-availability service management (HASM) is defined as information technology (IT) service management that is designed to meet the business demand for availability of critical IT and IT-enabled business services. HASM requires the use of the Six Sigma method and analytical tools applied to key service management processes and services; event and incident monitoring and management design; high end and high-quality infrastructure and application configuration; high-availability (HA) architecture and design; and special solutions that implement HA patterns and associated technologies.
