Abstract
We report a result of our evaluation to the QSM SLIM Suite tool, which was based on our actual data from real projects in Japan. The tool has functions for application software development estimation, and it computes effort and duration corresponding to inputted system size. We show that this tool is helpful for our ballpark estimation in an upstream of development phases, and that, by using the tool, the system size and tool's parameters to be inputted have a big influence on the calculated result. We also report a calculation tendency, some tips, and restrictions on estimation by using the tool. As a calculation tendency for estimated effort, even if we apply default parameters to the tool before our tools calibration, we reach a conclusion that we can get appropriate values for effort rather than the one acquired from other estimation tools, which are often smaller than actual effort. Our conclusion also includes that inputs of Lines of Code (LOC) size and duration's constraint influence to its calculation result.
