 Conclusion and Questions

3. Company Background
3
 World’s largest manufacture of storage devices
 Largest producer of server and PC hard drives in 1996
 Revenue of $4.4 billion
 Purchased Digital Equipment Corp. (DEC) storage business
in October 1994
 Competitors – Seagate, IBM, and Western Digital
 Outsource production of hard drives

4. Current Situation
 Legacy systems
 Material requirement planning (MRP) system maintained
separate databases and transactions had to be manually
consolidated
 Delays in obtaining updated information
 Acquisition of DEC caused implementation issues

5. ERP Project – Started April 1994
 Worldwide Ask Replacement System - WARP
 Three project teams
 Steering committee – VP’s of Finance, IS, Logistics,
Manufacturing, Purchasing, Sales, and Rep. from PW
 Core team – 16 managers from department and business
units
 Project team (100 Members) – Members from IS and
business unit key employees
 Teams analyzed and improved business process
 Selected Oracle, HP, and Price Waterhouse to assist with
ERP implementation
 Oracle 7 Database, Oracle Financial, and Manufacturing
Modules
 Expected implementation in Summer of 1995

6. Problems with the ERP Implementation
 Acquisition of DEC slowed implementation process of ERP
System
 Project was more complex with the acquisition of DEC
 Duplicate systems, processes, and artifacts
 Project was put on hold – Project teams focused on the DEC
acquisition (October 1994)
 ERP was restarted in January of 1995
 Project team had to redo a large part of the original ERP
implementation in order to take into account the DEC
acquisition

7. Quantum’s Current Systems
 Nine different legacy systems that could not share
information
 Legacy system kept each division’s transactions in separate
functional and business unit databases
 Information was manually consolidated, since databases
could not share information
 Gathering faxes, emails, and written information took four
days
 Closing the books took seventeen days
 Inventory availability could not be confirmed and delivery
could take days or weeks

8. Quantum’s Requirements for ERP System
 Sales people to take and confirm an order in real time.
 Sales have to be able to confirm a delivery time and follow
up to ensure that order was delivered in real time
 Ability to access current inventory and to reserve that order
for the customer in real time
 ATP (Available To Promise) – ability to confirm and allocate
inventory

9. ERP Implementation
Phased implementation:
Like the name implies means
that modules are
implemented one at a time or
in a group of modules –often
at a single location before
moving on to more locations.
 The installation of phase one could be
the implementation of finance,
controlling, accounts receivable,
accounts payable, and purchasing
modules.
 Phase two could be to include
materials management, production
planning, and quality planning
modules.
 Following phases mean the
deployment and implementation of
remaining modules over a period of
time.

“Phased” and “big-bang” are the two primary approaches used to
implement ERP systems.

10. Big-Bang Implementation
 Big-Bang Implementation: “everything is
changed at once!” Once an ERP solution has been
chosen to meet organizational needs –the system
goes from a test version to being the actual
system used to capture transactions in only a
matter of days.

11. ERP Implementation:
Consideration Factors
 Organizational size and complexity. This includes
factors related to the type of product that organization sells
and the size and complexity of the customer
 The organizations hierarchy and controls. Flat
organizations with loose controls would have more difficulty
deploying a phased implementation because its difficult to
maintain commitment throughout the process. Organizations
that have extensive hierarchy and tighter controls have the
necessary mechanisms in place to sustain a phased
approach
 Extent of the implementation: based on the number
of modules and the degree to which the organization
changes those modules.
