(Planning, Integration, Security & Administration)
An Intelligent Decision Support Environment for IT Managers and Planners


The diagram shows a more detailed view of PISA. At the heart of PISA, as shown, is the knowledgebase (KB) that consists of an extensive patterns repository, a commercial-off-the-shelf (COTS) database and planning models that are created during user interviews.  The KB is used by a family of advisors (yellow circle) that perform specific tasks (pink circle). The outermost circle (“the PISA crust”) represents the advanced capabilities module (ACM) that accepts the outputs produced by the PISA basic advisors and then helps the users to invoke detailed simulation and analysis tools, if needed.


Start with red arrow and go clockwise for a quick glimpse of PISA capabilities.


PISA is based on several years of academic research plus an active industrial consulting practice.


The main features of PISA are:


·         PISA advisors work with each other like a team of consultants. 

·         Instead of fragmented tools, all PISA advisors are integrated around a common knowledgebase.

·         PISA heavily relies on patterns (business patterns, application patterns, network patterns, security patterns, architecture patterns, SOA patterns) to quickly produce well documented plans.

·         PISA uses inferences and reasoning instead of asking the user too many questions.

·         PISA provides an extensive set of tutorials and explanations so that the user can be educated while developing plans. 

·         Over 400 experiments at 4 universities and 20 SMBs have shown that PISA produces high quality plans within an hour.

  • Network planning of a new or existing company
  • Security planning of a company based on a given network and application plan. 
  • SOA planning for integrating enterprise applications with internal and external applications based on SOA principles. 
  • Developing a business case for SOA based on cost, security and other quality of service issues.
  • Impact analysis of outsourcing a particular business function and/or application in terms of architecture and integration issues.
