Can Enterprise Architecture be Expressed as a Set of Partial Differential Equations?

By Srinidhi Boray

All complexities can be studied by applying simple Axioms, such that the laws of nature governing the system as a whole explains the EA behavior.

EnterpriseArchitecture = f (Process Architecture) +f (Performance) + f(Cost) +f(Architecture decisions) + f (Degree of Problem Complexity)+ f ( Process ofCreation) + f (Operations) + f (Market) …..etc

Change in any of the variable impacts the EA behavior, the concern is in understanding that a change happens and how this can be aligned with the desired objective.

Remember, increasing ‘Degree of Complexity’ reduces the ‘Degree of Freedom’, from Goldratt’s Theory Of Constraint ;

i.e, ‘Complexity’ and ‘Freedom of  Operation’ are inversely proportional.

ProcessArch = f(Business Arch) +f(Information Arch) + f(Solution Arch) + f (TechnologyArch) + f (Degree of Solution Complexity) + …etc

Processes= f (Function) +f (Business Ontology) + f (Degree of Business Abstraction) + f(Aggregated Cost)

Function=f (Activities) + f (physical resources) + f (information) + f (abstraction –businessrules) + f (actual cost) + ……etc

Since Enterprise Architecture entails both ‘analysis’ and ‘synthesis’., differential calculus and integration both could be applied.
