Scale calculation apparatus and computer readable medium

A non-transitory computer readable medium storing a scale calculation program to cause a computer to execute:

• a source code analysis process of identifying a dependency causing strength by which each function depends on a different function and a caused dependency strength by which each function is depended by a different function, as dependency strengths of one or more functions included in a source code;
• an influence analysis process of identifying one or more transfer functions that will each move to a different subsystem due to refactoring and identifying a dependency strength to be influenced by the refactoring, based on the dependency causing strength and the caused dependency strength that have been identified by the source analysis process with respect to the one or more transfer functions;
• and
• a scale calculation process of calculating a scale of the refactoring, based on the dependency strength to be influenced, which has been identified by the influence analysis process.

A scale calculation apparatus comprising:

• processing circuitry to:
• identify dependency strengths of one or more functions included in a source code;
• identify, from one or more functions associated with a first subsystem, one or more transfer functions that has each moved to a second subsystem due to refactoring, and identify a dependency strength that is influenced by the refactoring in an interface that has a dependency relationship with the one or more transfer functions, based on the dependency strengths that have been identified with respect to the one or more transfer functions;
• and
• calculate a scale of change in the interface due to the refactoring, based on the identified dependency strength that is influenced.
