- Benefits and Limitations
- System Benefits and Limitations
- Benefits
- Integration of data and applications
across functional areas of the
organization
- Improvements in maintenance
and support as IT staff is
centralized
- Consistency of the user interface across various
applications means less employee training, better
productivity and cross-functional job movemnts
- Security of data applications is
enhanced due to better controls and
centralization of hardware, sofware
and nerwork
- Limitations
- Complexity of installing,
configuring and maintaining
the system increases
- Consolidation of IT hardware,
software and people can be
cumbersome
- Data Conversion and
transformation from an old
system to a new one can be
tedious and complex process
- Retraining of IT staff and end
users of the new system can
produce resistance and reduce
productivity
- Business Benefits
and Limitations
- Benefits
- Agility to change for
growth and
maintaining market
share
- Share information across functional areas helps
COLLABORATION between employees
- Improving efficiency by linking and
exchanging information in real-time with
supply-chain
- Better customer
service due to
quicker
information flow
across
depamrments
- Efficiency of B Processes are
enhanced due to the re-engineering
of business processes
- Limitations
- Retraining employees - time and cost
- Change of business roles and
department boundaries can create
upheaval and resistance to the new
system

and
Drawbacks
Anmerkungen:
- •Benefits
–A
single-system instance is easier to maintain and support.
–Assessing
organizational change along with modifying the system to meet the needs of the
business will help to minimize risk.
•Drawbacks
–If a
system is modified, each modification will need to be analyzed in light of the
upgrade to see if it needs to be incorporated in the upgrade or removed.
–An
upgrade can sometimes turn into a re-implementation, which requires more
resources and time.

Process
- Vendor Research
Anmerkungen:
- •First step
is to identify a short list of vendors who will help to shape business
requirements.
•Identifying and
researching all aspects of a vendor package will assist companies in
determining the total cost of ownership.
•An exhaustive
list of vendors is important for a successful implementation.
•
•Ask department managers and subject matter
experts for their input in vendor selection.
•Including end-users
will help with change management and also help to gain trust for later in the
implementation.
•Consider
the following for vendor selection.
–Other businesses using the vendor
–The vendor’s financial position
–The vendor’s implementation philosophy and support issues
–The hardware and software infrastructure used to support the
ERP
–The vendor’s direction and currency of software
–The vendor’s release and upgrade strategies
–The vendor’s user-base involvement in defining future
functional changes
The vendor’s development and
maintenance resources

- High level
Vendor
- Needs and
Requirement
assesment
(business
requierements)
- Identification and documentation of user and
system requirements - BPR
Anmerkungen:
- •Two
major documents are often a result:
–Data and functional flow of departmental or business processes.
–Table or description of functions in each department and the
level of importance of each function.
–
•Identifying
vendor system functionality based on documented processes will help to purchase
a system based on facts.
- Request for
bid to
vendor
system
- RFB or RF proposals (RFP)
Anmerkungen:
- •Expensive
and time-consuming process for both the company and vendor, but it can yield
significant software savings when done right.
•
•RFB
should always include.
–Type of ERP system the company wants with specific
functionality
–Specified hardware and software infrastructure
–Training requirements
–Any specific contract issues required by the company
- Analysis
and
Selection of vendor
Anmerkungen:
- •Office
staff will need to evaluate functionality.
•
•IT
staff will evaluate the technology requirements.
•
•Contract
staff will need to evaluate the contract and pricing of the system.
•
•No
vendor will meet all requirements so vendor discussions and negotiations should
focus on the best fit for the business.
•
•Develop
and analyze the total cost of ownership (TCO).
- Vendor
Negotiation
Anmerkungen:
- •Talks
should center on the products included in the purchase and maintenance terms of
each product.
•
•Professional
services for the implementation or installation can be included or bid
separately.
•
•Contract
life cycle management will need to be addressed during contract talks.
•
•Things
every ERP contract should have:
–All deliverables must be clearly identified with delivery dates
associated.
–Ensure that you, the customer, have acceptance authority.
–Identify those responsible on both sides for contract
management and who has the authority to authorize changes to the contract.
•A
quality manager or contract monitor appointed by the program manager will have
primary responsibility for making sure both sides abide by the terms and
conditions of the contract.
•
•Changes
should only be made when necessary due to unforeseen circumstances, mutually
beneficial reasons, or unintended mistakes.
•
•Communicating
progress keeps all involved and will also help to maintain momentum.
•
•It is
best to over-communicate during this phase.
- Purchase system
- COST of ERP
Anmerkungen:
- •The
software installation has so many variables and total cost will depend on:
–The number of divisions it will serve
–The number of modules installed
–The amount of integration that will be required with existing
systems
–The readiness of the company to change
–Ambition of the project
- What is necessary to
rounding out an ERP
system
