This document presents a model for optimizing the strategy for resolving gaps between standard ERP features and specific customer requirements. The model takes into account customization options, their costs and benefits, and the vendor's planned feature releases. The objective is to maximize benefit achieved from satisfying requirements over time. Experimental studies show the model can generate a gap resolution strategy and highlight the impact of factors like customization preferences. A sample application illustrates identifying gaps in a lead management process and potential resolutions.
