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.

Example Scenarios for Using PISA :
- IT
planning for a new company or new
division/site of an existing company.
- Enterprise
application planning for a company
- 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.
Note:
This product was called CACIT during development. Any reference to CACIT in
older documents means PISA, i.e., PISA = CACIT
