What is ERP?
• ERP is a set of integrated business applications, or modules which carry out common business functions such as general ledger, accounting, or order management
• An ERP system is an attempt to integrate all functions across a company to a single computer system that can serve all those functions’ specific needs.
![Page 22: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/22.jpg)
What is ERP?
• It may also integrate key customers and suppliers as part of the enterprise’s operation.
• It provides integrated database and custom-designed report systems.
• It adopts a set of “best practices” for carrying out all business processes.

Selecting ERP Vendors
• Depending on your organization's size and needs there are a number of enterprise resource planning software vendors to choose from in the large enterprise, midmarket and small business ERP markets.
• Large Enterprise ERP (ERP Tier I)The ERP market for large enterprises is dominated by three companies: SAP, Oracle and Microsoft.
![Page 31: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/31.jpg)
Selecting ERP Vendors
• Midmarket ERP (ERP Tier II)For the midmarket vendors include Infor, QAD, Lawson, Epicor, Sage and IFS.
• Small Business ERP (ERP Tier III)Exact Globe, Syspro, NetSuite, Visibility, Consona, CDC Software and Activant Solutions round out the ERP vendors for small businesses.
![Page 32: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/32.jpg)
ERP Implementation Approaches
• The big bang – install a single ERP system across the entire organization
• Franchising – Independent ERP systems are installed in different units linked by common processes, e.g., bookkeeping.
• Slam dunk – install one or several ERP modules for phased implementation of key business processes.
![Page 33: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/33.jpg)
What makes ERP different
• Integrated modules• Common definitions• Common database• Update one module, automatically
updates others• ERP systems reflect a specific way of
doing business• Must look at your value chains,
rather than functions
![Page 34: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/34.jpg)
Benefits of ERP Systems
• Improving integration, flexibility • Fewer errors • Improved speed and efficiency • More complete access to information• Lower total costs in the complete
supply chain• Shorten throughput times• Sustained involvement and
commitment of the top management
![Page 35: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/35.jpg)
Benefits of ERP Systems (cont’d)
• Reduce stock to a minimum• Enlarge product assortment• Improve product quality• Provide more reliable delivery dates
and higher service to the customer• Efficiently coordinate global demand,
supply and production
![Page 36: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/36.jpg)
Benefits of ERP Implementation(META Group Survey)
• Benefits are mostly in terms of cost containment rather than revenue increase.
• 53 companies (out of 63) reported annual savings of over $5 millions with the median annual saving of $1.6 million. Nine companies account for 73.4% of the reported savings.
• The study found that much of the ERP value is in indirect, non-quantifiable benefits.
• A number of companies surveyed had a negative net present value.
![Page 37: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/37.jpg)
Major Challenges to ERP Implementation
• Limitations of ERP technical capabilities• Inconsistency with existing business
processes• Costs - implementation (hardware,
software, training, consulting) and maintenance
• Impact on organizational structure (front office vs. back office, product lines, etc.)
• Changes in employee responsibilities
![Page 38: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/38.jpg)
Major Challenges to ERP Implementation
• Flexibility of software system upgrades
• Implementation timelines• Availability of internal technical
knowledge and resources• Education and training• Implementation strategy and
execution• Resistance to change
![Page 39: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/39.jpg)
Hidden Costs of ERP
• Training• Integration and testing• Data conversion• Data analysis• Consultants• Replacing best and brightest staff after
implementation• Implementation teams can never stop• Waiting for ROI• Post-ERP depression

Difficulty in implementation
• Very difficult• Extremely costly and time intensive• Typical: over $10,000,000 and over a
year to implement• Company may implement only
certain modules of entire ERP system• You will need an outside consultant
![Page 42: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/42.jpg)
ERP Implementation - Key Enablers (APQC Best-Practice Report)
• The organization is prepared for the change.• The executive leaders are active and visible in
their support.• The initiative is seen as a business imperative
by the organization.• The resources are available to conduct the
project completely.• A good packaged system is used and not
customized.• The user group is trained to use the software
before it is implemented.
![Page 43: Introduction to ERP - Stu](https://reader033.vdocuments.mx/reader033/viewer/2022061612/563dbabd550346aa9aa7a5b3/html5/thumbnails/43.jpg)
Common Pitfalls
• Do not adequately benchmark current state
• Did not plan for major transformation• Did not have executive sponsorship• Did not adequately map out goals
and objectives• Highly customized systems to look
like old MRP systems
