A computer 
system (20) is provided with a development 
server (26) with a plurality of 
subject matter expert (SME) terminals (22) and a production 
server (28) with a plurality of user terminals (24). The development 
server (26) supports several 
software components including a knowledge 
database (46), a code generator (48), and fluid object material (50). The production server (28) also supports several 
software components including an production copy of the fluid object material (50A), and 
software wrappers (152,154). An instantiation modeler (156) and a 
user interface (44) are provided on the user terminals (24), and a SME interface (42) resides on the SME terminals (22). The SME interface (42) is operative to guide a SME through entry of rules into the knowledge 
database (46), and the code generator (48) is operative to automatically generate 
source code that is the fluid object material (50) for implementing the rules input into the knowledge 
database (46) by the SME. The production copy of the fluid object material (50A) is transmitted to the production server (28), and the instantiation modeler (156) is operable to instantiate a class into a morphable object. As a user enters information, the instantiation modeler (156) repeatedly morphs the morphable object into more mature objects and the 
user interface (44) changes to reflect the morphed object. The wrappers (152,154) are operable to permit the SME to update the rules and recompile the fluid object material (50) while the users interact with the user interfaces (44).
