The second case states that the company doesn’t have software to support ERP. Perhaps its legacy systems are home grown, and they contain logic that simply won’t work in an ERP environment. In this case, we recommend you buy one of the many low-cost PC-based ERP/MRP II packages that are available today. You can probably get everything you need for less than $100,000. And most of it is quite good—fairly complete functionally and very user friendly. Since the price is relatively low, you can buy it and use it for a year or so, and then if need be, replace it with a full-blown set of ES software if you wish to head in that direction. Please keep in mind that this ERP/MRP II software is not an ES; it won’t be truly stand-alone software;and it will in effect be “bolted-on” to your existing software.
