Root Cause Analysis

Enterprise Architect has a number of tools that can assist with Root Cause Analysis, allowing the context of the problem to be identified and the analysis of the causes to be modeled. One or more Issue elements can be used to describe the Problem Statement in detail, including the context of the problem, which might be business or technology processes or application components or hardware.

A decision diagram can be used as a way of describing the causes using the Five Whys approach.

Maintenance Items

One or more Issue Maintenance Items can be used to record a problem statement that helps to formally describe the problem. These can be added to the repository at any level from a high level Package such as a Functional Requirements Package down to an individual Requirement level or for any other element type. Applicable metadata can be stored against each item including its Name, Description, Status, Priority, who it was raised by, Completion details and more.

Decision Tree

A Decision Tree is a diagram that is part of the Strategic Modeling Technology and uses a visual notation to represent a series of decisions and possible outcomes. It can be used in either a descriptive or predictive manner to visualize outcomes and decision points. The Decision Tree diagram can be used to create a 'Five Whys' diagram starting with the problem and fanning out.

Requirements Diagram

The Requirements diagram can be used to model the problem statement and the context of the problem, using an Issue element available from the 'Requirements' pages of the Diagram Toolbox. Other elements that are relevant to the problem - such as things that are impacted by the problem - can be recorded on the diagram. These can include Business Capabilities, Business Processes or Technology Capabilities, Services, Applications or Hardware.
