This standard provides for the core set of attributes for classification of failures and defects. It is recognized that there are other attributes of failures or defects that are of unique value to specific applications or business requirements. This standard is applicable to any software (including operating systems, database management systems, applications, testware, firmware, and embedded software) and to any phase of the project, product, or system life cycle by which the software is developed, operated, and sustained. Classification attributes are unaffected by the choice of life cycle model, and that choice is outside the scope of this standard. Some tailoring of classification attribute values based on the chosen life cycle is expected and consistent with the intent of this standard.


The purpose of this standard is to define a common vocabulary with which different people and organizations can communicate effectively about software anomalies and to establish a common set of attributes that support industry techniques for analyzing software defect and failure data.

NASA Notes:
  • This document can be used for defining a uniform approach to the classification of anomalies found in software and its documentation. The document describes the processing of anomalies discovered during any software life cycle phase and presents comprehensive lists of software anomaly classifications and related data items that are helpful to identify and track anomalies. Use of this standard will allow meaningful collection of metrics across projects.
