Finding relevant IfSQ Standards:

Information-Hiding makes large programs 4 times easier to modify
Large programs that use information hiding are a factor 4 easier to modify than programs which don't

IfSQ Defect Indicators:

DP-5—Information Exposed
Information internal to a module has been made available to other modules. The practice of information hiding makes it much easier to modify large programs.
