Assessment Assessment Traces
Here’s My Claim
•
A Claim is a type of Assessment in AWB
•
Make an initial Claim by creating an assessment.
•
The claim can be found in the Analysis Palette
•
Claim details are shown in the Assessment Property
View
11
Here’s My Argument & Evidence
•
Additional Assessment
records can be made to
record Arguments
•
Evidence can be linked
to the Claim’s
arguments. Evidence
may be other
Assessments, or Project
Artifacts.
12
Discovery – via view traces
13
•
A completed Claim can be
followed, using traces,
from the top Claim
Assessment.
•
In addition, the Claim can
be seen as attached when
looking at other Artifacts
or Assessments.
Conclusion
The AWB’s robust tracing and graphing capabilities
make it the ideal tool to seamlessly integrate
Evidence-Based Assurance into the IV&V Program in
a dynamic, useful, and easy to implement fashion.
The AWB’s advantage over other methods is its ability
to create Assurance Cases and record evidence
dynamically throughout the life of the project,
without requiring extensive additional effort from
analysts to create separate diagrams or documents to
organize and illustrate their evidence.

AMF / AWB Core to
IV&V Effort
•
assess AWB as a tool for team’s analysis efforts.
•
The AWB core tool at NASA IV&V going forward.

The Analyst Workbench is an IVV-developed Eclipse tool that interfaces with the AMF data structure to provide dynamic traceability views between requirements, design documentation, analyst assessments, and other project data. The AWB provides a powerful visual representation of project data and data relationships that other tools lack. This demonstration will provide an overview of the capabilities of the AWB, showing the tool’s ability to capture evidence for assurance cases, and enhance both the quality and quantity of work for analysts and managers. Attendees will see a general overview of the tool, and attain the knowledge necessary to assess if the AWB may be a valuable tool for their team’s analysis efforts. The AWB will become a core tool in the analysis and management efforts of NASA IV&V going forward.
A detailed look at the IV&V Program's Evidence-Based Assurance with the Analyst Workbench, including Analysis Management Framework, Perspectives, and more. Explore Claims, Arguments, and Evidence within the program.
