This book is not only on ERP but also covers other enterprise applications like PLM, CRM, SCM, SRM etc. which are growing at a faster rate than core ERP application as the ERP market is getting saturated. This text is intended for students (who want to learn these topics for the first time), for practicing executives (who want to move to a career in ERP from their traditional role in finance, operations, marketing or HR and want to know what ERP or CRM is all about) and finally for managers who are responsible for selecting, implementing and maintaining an ERP/CRM/PLM/SCM package in their organisation.
