Is ROI for Mfg Operations Systems required.

Sometimes. Many and most manufacturers require some kind of Capital Expenditure (CapEx) justification where somekind of ROI has to be constructed for any IT project over a given amount, say $100K. Some process are better than others but only 15% actually measure results according to MESA International. However, most company as usaul these day are missing the big fish. A detailed ROI validated the system's requirements, migration path and business expectations if it is based on what level of improvement over what time period is expected on a granualar level from the actual quantified waste streams from a value stream analysis of the product workflow. Otherwise, the requirements have no real connection to business expectations.
