A method for determining an extent of code changes upon implementation of a software modification has the steps of: registering the number of software code components and the respective number of lines of code of each software component of a software code before the implementation of the software modification, implementing the software modification by changing the software code, determining the number of software code components that have changed due to the implementation of the software modification, determining the number of lines of code of each software component that have changed due to the implementation of the software modification, and determining an invasiveness value on the basis of the determined number of software code components that have changed and determined number of lines of code that have changed, the invasiveness value being indicative of the extent of software code changes upon implementation of the software modification.

Software quality evaluating system and methods for determining an extent of software code changes

A method for analyzing changes in a software code may have the steps of: inputting a plurality of different versions of a plurality of software artifacts to a change analysis device, deriving design constructs of the software code of the software artifacts by using an abstract syntax tree analysis, with the software code differences between the different versions of each of the software artifacts, classifying the derived design constructs of each of the software artifacts according to the compared software code differences, and outputting a visualization of the design constructs of each of the software artifacts, which visualization is structured according to the classification of the design constructs.
