I'm been working with Engineering and Maintenance during my entire career. Already, I saw many ERP implementation and never the so called "Maintenance" module has been implemented. This happened with first versions of [MFG/PRO](https://www.qad.com/mfgpro) and more recent versions of [QAD](https://www.qad.com/). Even on latest change to [Oracle ERP](https://www.oracle.com/scm/#rc30maint). Maintenance module has been left out of the package. Reasons: -1. Cost over 200.000USD. Difficult to justify the investment based on real ROI that the system can bring based on the limitations. +1. Cost over 200.000USD.
