Companies must confront an increasingly competitive environment with lean, flexible and market oriented structures. Therefore companies organize themselves according to their business processes. These processes are more and more often designed, implemented and managed based on standard software, mostly ERP or SCM packages. This is the first book delivering a complete description of a business driven implementation of standard software packages, accelerated by the use of reference models and other information models. The use of those models ensures best quality results and speeds up the software implementation. The book discusses how companies can optimize business processes and realize strategic goals with the implementation of software like SAP R/3, Oracle, Baan or Peoplesoft. It also includes the post implementation activities. The book cites numerous case studies and outlines each step of a process oriented implementation, including the goals, procedures and necessary methods and tools.
