Rational Team Concert Workflow Visualiser

Overview

Example workflow diagram Workflow Visualiser is a tool that takes the RTC process configuration XML and exports graphical representation of the workflows included in the configuration.

Motivation

The most typical task I'm facing at new RTC deployments is analysis of their workflow and its implementation in RTC. The usual procedure is:

  1. Meet with the customer to try to understand the workflow (states, transitions)
  2. Draw the workflow in Microsoft Visio and discuss the Visio files with customer
  3. Implement the workflow in RTC

This would be all great it there wasn't number 4 – implement the changes the customer finds after the implementation in RTC, which usually repeats several times. In this moment the Visio diagrams and the RTC implementation get out of sync and it is not easy to keep them synchronized. Workflow Visualiser helps in this step as I can export the real diagram and either send it to the customer for review or redraw it in Visio.

Another case in which this tool comes handy are big workflows (with 10< states). Although the transition table in RTC workflow designer is straightforward, checking such a workflow is not an easy task. Seeing a graphical representation of the workflow makes it clear.

Running the program

The program has to be invoked from command line and the command line arguments are:

Usage: java -jar visualiser.jar [options] source-xml-file
 Options:
  -h|--help Print help and exit
  --version Print help and exit
  -d|--dot Location of dot executable (defaults to /usr/bin/dot)
  -o|--out Output directory (defaults to /tmp/)
  -f|--format Output format (see the output formats of dot) (defaults to pdf)
  -s|--source Save the DOT source file in the output directory

Examples

Windows example PDF
  • JAR stored in C:\visualiser.jar
  • Process XML configuration file saved in process.xml
  • Graphviz installed in standard location
  • Export diagrams in PDF format to „C:\temp“
java -jar "C:\visualiser.jar" -o "C:\temp" -d "C:\Program Files\Graphviz2.26.3\bin\dot.exe" process.xml

Windows example PNG
  • JAR stored in C:\visualiser.jar
  • Process XML configuration file saved in process.xml
  • Graphviz installed in standard location
  • Export diagrams in PNG format to „C:\temp“
java -jar "C:\visualiser.jar" -o "C:\temp" -d "C:\Program Files\Graphviz2.26.3\bin\dot.exe" -f png process.xml

Linux example
  • JAR stored in ~/visualiser.jar
  • Process XML configuration file saved in process.xml
  • Graphviz installed in standard location (/usr/bin/dot)
  • Export diagrams in PDF format to ~/diagrams
java -jar ~/visualiser.jar -o ~/diagrams process.xml
