ERP survey and related research are well articulated. Dimensions are also diverse. It may relate to software, technology, architecture and attributes of product, process etc. I suggest to focus attention to the purview of work and seek support.
Reengineering a business process is more like creating a new line of business operation, still for the same product. A business process is mostly reengineered when their is need to reduce operational costs, either still maintaining the same level of productivity or increasing it. A business majorly has three entities:
Entity 1. The business name and all the functionaries allowing it to exist as a legal business entity; the principal owners inclusive.
Entity 2. The product or service and all necessary materials/services to create the product or service from start to finish.
Entity 3. The human resources and all necessities to retain/sustain these human resources.
Reengineering occurs only at and the outcome of reengineering affects, very greatly, . Of course, this is being implemented by .
Actually, the need to reengineer is forecasted by the Enterprise Resource Planning (ERP) Software System being used to run the business. So, the only way to measure anything is through the ERP Software System that forecasted the need for reengineering in the first place. I once worked with Promasidor Nig. Ltd. in 2006 as a software engineer maintaining the HansaWorld ERP/CRM system used by the company. The HansaWorld software has both the user interface and the reprogramming programmer interface. It is through the reprogramming programmer interface you get to see the dynamics of every element in a business process. Hence the ability to forecast.
