SOFTWARE PERFORMANCE SEQUENTIALLY-PREDICTING METHOD AND PREDICTING SYSTEM

PROBLEM TO BE SOLVED: To provide a software performance sequentially-predicting method and a predicting system method that achieve performance improvement and quality improvement by avoiding performance measurement through embedded software execution on an actual embedded system and by making the determination through predictive estimate of performance in large-scale software development conducted by multiple people.SOLUTION: With respect to software that is executed before registration of source code change, a software performance sequentially-predicting system, at the time of software development, executes steps of: calculating a performance reduction ratio of an input source code; and providing notification of a determination result externally when the performance reduction ratio is equal to or greater than a predetermined value.
