Besides being one of the most irritating presentations I have ever heard... the entire heart of ERP was missed. This is due to the use of Business People who have no concept of the true nature of ERP. The heart is relationships between components. Every component must be not only identified but structured in a parent-child relationship . This relationship identifies 'What you need' and 'When you need it'. Signed...
