Quick and simple procedures to assess software reliability and facilitate project management

Abstract

A software reliability model is considered that is easy to implement, use, and interpret. The model works extremely well in the latter stages of testing. A complete history of failures does not need to be stored in a data base or maintained. This reduces the cost of assessing software reliability. Furthermore, it is possible to use the model to estimate software reliability when failure statistics have not been extensively collected. Various estimation procedures are discussed that can aid in project planning. The use of these estimation procedures is illustrated through two sets of actual failure data. © 1982.
