Analyzability: Dependencies and Coupling

• Data Coupling: data passed to a routine
• Stamp Coupling: data passed to a routine, but only small part is used
• Control Coupling: data affects control decisions
• Temporal Coupling: behavior depends on the order elements are called (also lack of reentrancy)
• Common Coupling: sharing of data through global variables
• External Coupling: implicit sharing of knowledge of data formats or protocols
• Content Coupling: one module depends or modifies internal workings of another
