A computer implemented problem solving system utilizing an information storage infrastructure and a flexible development environment for data storage, includes a stored, user modifiable program including a problem solving rule set relevant to a problem to be solved, a stored, user modifiable set of vocabularies related to a problem to be solved, at least one stored, user modifiable knowledge set relevant to a problem to be solved, and stored, user modifiable individual user preferences relevant to a problem to be solved. A computer implemented problem solving method utilizing an information storage infrastructure and a flexible development environment for data storage, includes generating screen displays on a display screen, and entering a problem identified by an initial assessment to the computer at a designated place in one of the screen displays. The method further includes selecting from at least one of the screen displays at least one item from at least one of: a stored, user modifiable set of vocabularies related to a problem to be solved, at least one stored, user modifiable knowledge set relevant to a problem to be solved, and stored, user modifiable individual user preferences relevant to a problem to be solved and entering the at least one item to the computer at a designated place in one of the screen displays.
