Focussing on costs rather than benefits
Everyone wants their ERP implementation to be delivered on time and on budget. In general that’s considered a success. As a consequence it’s natural during the ERP selection project to ensure that software and implementation costs are kept within initial expectations.
However, this approach takes no account of the ability of the solutions being assessed to deliver the expected business benefits. Everything else being equal, a solution that costs 15% more but helps you achieve multiples of that in financial benefits over a period of time is clearly a better option.
