Before you start with a project for improving, professionalizing and streamlining your business process, you first have to investigate if there is a business case for such a project. A professional solution does cost you some money, but in the end should gain money. If you are in a stable environment, with only a limited number of users and little change and simple requirements, why not use more general applications like excel or your ERP? There are good examples of effective and powerful systems in ms-office. The only big disadvantage of these systems is the maintainability and the dependency on one or few persons within your organization. It’s always difficult to measure abstract things as complexity and future change. However, if you are losing time and thus money, because you do not have accurate and fast insight in your business, you should consider a more flexible and professional approach.
