1. Introduction

Excerpt

This topic contains the complete list of software assurance/safety metrics that are suggested for use with the SA tasks in NASA-STD-8739.8.

These suggested metrics will provide SA and safety personnel with much of the information they will need to assess both the software assurance/safety work, as well as providing information to help with the monitoring of the software engineering progress.

The Metrics Table tab shows the set of metrics in a table and provides a way to download an Excel file. The Excel file contains the same metrics but has the capability of being able to filter the columns. This provides an easy way to see which metrics are associated with a particular SWE, and to filter out SWEs that may be tailored out in your project. These tables provide information on potential phases in which each metric might be collected. Be sure to read the information at the top of each metrics sheet for more specific information on the use of the tables.

Each project should review the table and decide which metrics they want to collect, based on the metrics that they think will provide them with the most information for their activities.

1.1 Metrics Table

The table below provides suggested metrics for the SWE requirements in Sections 7.3 of the SA tabs in the SWEs of this Handbook.

There are multiple “Metrics Types”, and each type includes optional “Measurements” by life cycle phase for the “Associated SWE Requirements”. Many of the measurements were reworded to clarify them or to make them more generic so they could be applied in multiple places. For example, the word “non-conformance” was used in lieu of findings, problem reports, defects, or errors to cover all types of non-conformances. When choosing a measurement, change the word “non-conformance” to the one that best fits the situation to be monitored. (Note: these may be collected by the project and analyzed by SA.) Projects should choose a set of measurements to provide information on the project being implemented. The measurements do not have to be implemented as written. They may be modified to best fit the characteristics of the project.

The life cycle phases listed below indicate the recommended phase the data may be collected (color has been added only to provide a visual reference as you scroll down the page). However, it does not mean it has to be collected in each phase. Establish a set of measurements that best suits the project taking into consideration the size and applicability of the activity. For example, if a configuration audit metric is collected, it may be appropriate to collect those measurements during most of the life cycle phases listed, but the project may not be doing configuration audits in all the listed phases.

  SWE requirement numbers listed in the table below are associated with the SA tasking in NASA-STD-8739.8 
Swerefn
refnum278
  but may not be the only applicable SWE requirement for a particular metric.

There are a few measurements that are required specifically for analysis in NASA-STD-8739.8. They are listed in bold type. Other measurements listed in the charts should be considered when performing the tasking activities associated with the SWE numbers for the metric.

Note

In some cases, in order to understand the full context of the metric listed in a requirement, look at the metrics in 8.18 to see other measures that contribute to the metric in a particular requirement.

For example,  the table shows SWE-036 with the metric, “# of software components (e.g. programs, modules, routines, functions, etc.) planned versus the number actually released in each build.” SWE-036, task 1c would provide the planning information for the scheduled deliverables. However, in order to complete the metric in SWE-036, it would be necessary to use the information collected in SWE-077 to get the  “# of components actually released in each build.”
