A FRAMEWORK FOR MEASURING CRITICAL SUCCESS FACTORS OF LARGE - SCALE SOFTWARE SYSTEMS

Large-scale software systems (LSS) are complicated due to their huge size and the number of applications and services they provide. Implementations of such systems are surrounded by a group of influential factors, termed as Critical Success Factors (CSFs). High cost of implementation is always associated with LSSs coupled with high efforts. Consequently, assuring a successful largescale software system implementation is not an easy job. We introduce “CSF-Live!” which is a new method for measuring critical success factors of large-scale software systems, e.g. ERPs. CSFLive! allows for monitoring and controlling the implementation of large scale software systems based on continuous measurement. Our measurement model is based on the Goal/Question/Metric paradigm (GQM) which yields a flexible framework enabling the measurement of one or more of the critical success factors during a particular implementation. We present measurement formulas for three CSFs: data accuracy, top management support, and project management
