Enterprise Resource Planning




                    notes          The concept of SCM dates back to the late 1950s where research on system dynamics explored the
                                   systemic properties of enterprises collaborating in chains. Business dynamics dealt with delays
                                   and information flow and addressed contemporary problems like the “Bullwhip effect” which is
                                   still a significant issue.
                                   There  was  no  business  implication  of  this  research  due  to  the  immaturity  of  the  available
                                   computers, but also the success of the emerging MRP systems postponed interest in this approach
                                   for decades. The concepts re-emerged at the beginning of the 1980s initially in operations and
                                   logistics research, and by the 1990s many businesses were implementing major structural changes
                                   in their supply chain.
                                   SCM took a systems approach to planning and controlling the material and information flow
                                   from the raw material to the final customer, and therefore SCM was defined as:

                                   1.   The management of upstream and downstream relationships with suppliers and customers
                                       to deliver superior customer value at less cost to the supply chain as a whole.
                                   2.   The  strategic  management  discussions  dominated  the  initial  research  agenda  but  the
                                       software industry responded to the new business requirement by producing a new breed
                                       of add-on or “bolt-on” software to ERP called Advanced Planning and Scheduling (APS)
                                       systems  .APS  was  enabled  by  refining  the  mathematical  programming  models  and  in
                                       particular the genetic algorithms applied to solve the network problems of an entire supply
                                       chain. The APS systems facilitate the central management of the supply chain activities and
                                       processes in real time, essentially by extending the MRP/II planning concepts to encompass
                                       the entire supply chain, and as a result the systems in effect are SCM systems.

                                   3.   Although  the  SCM  concept  deals  with  the  entire  supply  chain,  the  perspective  of  the
                                       upstream SCM and the downstream SCM differs.
                                   4.   Downstream,  SCM  deals  primarily  with  demand  management,  order  fulfillment,
                                       replenishment  and  collaborative  relations  with  customers,  e.g.  collaborative  planning,
                                       forecast  and  replenishment  (CPFR).  Some  researchers  even  proposed  demand  chain
                                       management (DCM) as a new perspective .The management of market information became
                                       important and the software vendors targeted these new requirements with the customer
                                       relationship management (CRM) systems.
                                   5.   Upstream, SCM primarily deals with issues of managing the supplier networks. Issues
                                       like supplier relations, partnerships, competence development and technology transfer are
                                       barriers for developing the supply chain. Practices based in the just-in-time (JIT) philosophies
                                       were implemented in the supply chain and new concepts like vendor managed inventories
                                       (VMI) emerged. The traditional purchasing task became strategic sourcing and the new
                                       tools required were gathered under the supplier relation management (SRM) hat.
                                   6.   Managing  information  in  an  inter-organizational  context  has  become  critical  and  the
                                       emergence of the internet and the range of related e-business technologies created new
                                       opportunities and threats to supply chain managers.

                                   11.2 What are the added features in erp ii?


                                   ERP has a big challenger from its own community. Its successor ERP II has been talked about
                                   much. However there are also arguments that it is merely an extension of ERP. ERP and ERP
                                   II have lot of differences. The popular myth that ERP II is the extension of ERP is not true. The
                                   comparative features of ERP and ERP II will explain them clearly.
