Evaluating Reliability of a Software Module Using Development Life Cycle

摘要

Reliability of one or more software modules is projected according to a current state in a development life cycle of the software modules and any of various additional indicators. Preferably, a data processing support provider separate from the service-providing enterprise maintains historical field support data concerning significant field defect events with respect to various resources, and uses this data for projecting reliability of the resources. Preferably, software module reliability projections are used to support an analysis of risk of degradation of a service specified in a service requirements specification when provided by a configuration of data processing resources specified in a configuration specification.

主权项

1. A method for evaluating reliability of a first software module, comprising:
recording in a data processing system a state in a software module development life cycle of said first software module; recording in said data processing system historical reliability data with respect to said first software module; using said state in a software module development life cycle of said first software module and said historical reliability data with respect to said first software module to automatically determine, with said data processing system, a reliability of said first software module corresponding to at least one of (a) a current state in a software module development life cycle of said first software module; or (b) a future state in a software module development life cycle of said first software module; and providing results of said using said state in a software module development life cycle of said first software module and said historical reliability data with respect to said first software module to automatically determine a reliability of said first software module to a user, wherein said providing results of said using said state in a software module development life cycle of said first software module and said historical reliability data with respect to said first software module to automatically determine a reliability of said first software module to a user comprises outputting reliability of said first software module to a computer-implemented process for evaluating degradation of service risk for a service provided by a set of data processing resources, said set of data processing resources containing said first software module, and providing results of said process for evaluating degradation of service risk to said user.
