The chapter reports the implementation and validation of the knowledge process visualization technology that extends the basic capabilities of the Semantic MediaWiki platform. The Design Project Visualizer has been developed in the ACTIVE Integrating Project of the Seventh Framework Programme of the European Union for the case study in the engineering design in Microelectronics and Integrated Circuits. The concept of knowledge process visualization is based on the paradigm of project navigation. The knowledge workers in this domain are design project managers, designers, and design support engineers. The visualization suggests optimized performance, points to the bottlenecks in executions, and fosters collaboration in development teams. The authors describe the software prototype architecture and implementation. The components and the solution for process knowledge transformation between ontological representations as well as the visualization are presented in detail. Validation results indicate that the solution is helpful in providing expert assistance to design project managers performing their typical tasks of project planning and execution management.
