This paper first computes the Complexity increment by taking four complexity metrics WMC (CK), CMC (Li), CC (BS) and CCC (S&B). The maintainability index of the successive version has been computed at the system level. The tracking of the number of classes added and deleted has also been obtained for the archaeology of successive versions. The understandability and the maintainability of software are then mapped with the trends of complexity increment, change in number of classes added and deleted and the Maintainability index. The complexity increments between successive versions give an indication towards the maturity level of software. These metrics are empirically evaluated with 38 versions of JFree Chart and nine versions of three live project data at the system level.
