2. To appreciate the importance of Supply Chain Management in developing ERP
3. To know what an ERP system is, what its components are and appreciate its basic architecture
4. To understand how ERP can be managed as an implementation and an operation.
5. To possess a more detailed understanding of SAP ERP offerings
6. To have a strong understanding of the costs, weaknesses and dangers of ERP systems
7. To have an overview of the critical (political, social and ethical) views of ERP systems
1. The Context of ERP
Problems of Organisation: Information
• Globalisation, M&A, take-overs
• Functional / Departmental divisions– Disparate systems lead to time delays
– Redundant systems (e.g. 24 different general ledgers)
– Huge software maintenance expenses
• Lack of common data structures – Inconsistent terminologies
– Field mismatches in data bases
– Weak Management Information
– No “Process” information (e.g. how long does it take to order X?)
– Data redundancy / overlap
1950 – 1970: Out of Fordism
• Control, efficiency & scientific management
• 1950s: Inventory Control Systems
• 1960s: Materials Requirements Planning (MRP)
• 1970s: Manufacturing Resource Planning (MRPII)
• But, failures due to:– Organisational & technical complexity
– Long & difficult implementations
– Manual rather than automated
1970 – 2000: The Power of Computing
• 1980s– OO data-driven software & client / server models– Automation of processes– Data-mining & warehousing
• Rise of integrated SCM & BPR– Global supply-chains– Automated value-chains– Re-engineering of e2e processes– Interation with HR, warehousing, CRM & MIS
• Success of 1990’s– Fuelled by Y2K– Internet / Intranet roll-out– Powerful processors– Development by SAP & BAAN
ERP 2003
• Event Driven Processes
• Supported by BPR
• Consulting expertise
• Plug & Play Architectures
• Move towards Decision Making Software
2. Supply Chain Management
(SCM)
Importance of Supply Chain Management
Supply Chain Problems
UNCERTAINTY
In demand forecast
In delivery times & production delays
POOR COORDINATION
With Internal units and business partners
Ineffective customer service
High inventory costs, loss of revenue & extra cost for expediting services.
Push v Pull Supply Chains
Successful Supply Chains
• Extends the chain all the way from sub-suppliers to customers
• Integrates the back-office operations with those of the front office
• Focuses on customer demand generation and service
• Is proactively designed as an “extended enterprise”
• Optimize the value added by information services
ERP
3. What is ERP?
Definition• Integrates disparate information from e.g. finance, accounting,
distribution, production, logistics, human resource, etc.,
• Into a single, enterprise-wide, shared database
• A software architecture that sits on a common database and is supported by a single development environment
• It is customized to support an organization’ s business processes.”
• Interacts with an integrated set of applications, consolidating all business operations in a single computing environment.”
• To provide useful real-time information to support managerial decision making
Practical definition….
• ERP stands for Enterprise Resource Planning– it does not do any planning
– forget about resource too…
– remember the “enterprise”. This is ERP’s ambition.
• Typically, ERP combines Finance and HR departments
• ERP systems automate and standardise business processes
• ERP should contain a “best practice” model of the business

ERP Benefits
• Improved efficiency, lowered costs.– Average expected administrative cost reduction = 30%
• Controlled operational disorder– Streamlining of business processes
• Reduce size and cost of the company’s IT– Maintenance of outdated legacy systems
• Managerial effectiveness– Empowered users
– Informed management decisions
4. Managing ERP
Roles• Vendor
– delivery of software– initial training for key users – project support– quality control– conduct modifications
• Consultants– bring/transfer know-how about package– development of detailed work-plans– optimize fit between processes and software– analysis of customization issues
• Company– learn/assimilate information about software (independence!)– make people sufficiently available (reallocation of responsibilities)– keep up motivation (monitoring progress)– responsibility for conversion (data extraction, interfaces) programs
ERP Options
• DIY- Expensive & cumbersome- Few do this
• ASP- The customer leases services rather than builds them.- Services may include SCM, ERP, etc- Good for SMEs – lack resources to build or buy their own- Clients save money,…- But..… the ASP may only offer a 5-year contract to tie in customers- But……ASPs tend to offer a "one size fits all" solution
• Integrated packages-OTS- e.g. SAP R/3
What Approach?
• Big Bang
– Implementing all modules at the same time
– One cutover date for the entire new system
– Very risky
– Cheaper (in total - if everything goes well)
– Faster
• Phased approach
– Implement modules in different phases.
– More expensive (development of temporary interfaces)
– Takes longer (danger of losing speed)
• Series of “Small Bangs”
– Implement subgroups of modules in parallel
– Best of both worlds?
ERP Design• Process-oriented design: based on the operation process.
• Architecture
– One database for all data (minimal redundancy)
– Modular application (independent, but integrated modules)
– Software functionality configurable to customer’s requirements
• Master Data
– Information captured once
– Visibility though Business process
– Workflow management
– Event Triggered processes
Typical ERP Project1. Understand the problem
– Understand business and how package fits, – Determine characteristics of current system– Arrange for training, – Determine how stored data will be migrated.
2. Define the solutions (most critical!)– Define all concepts associated with software implementation– Run simulations of app. processing, – Make definitions for master files, tables, parameters, – Establish degree to which company needs to adapt package.
3. Put hands to the task (most difficult!)– Load initial data– Develop, test, place customization into operations; – Develop, test interfaces put them into operation; – Document new procedures, test new work environment.
4. Make it happen– Run software in parallel w/ old system– Support users– Make final adjustments– Release system for final use.
5. Keep on – going live is just a milestone!

Report & Query Requirements
• Information is produced in standard reports or via Queries
• eg. Financial reports: income statements and balance sheets
• Queries are helpful seeing where the reports do not meet user needs
• Too many queries will slow the system down
Implementing ERP
• Configuration
– Parameters (rules) for business processes
– Local requirements
• Understanding your own business processes
• Making a fit possible
–Reengineering processes - adopting a “best practice”
–Reengineering the system
Successful implementation….?
• Lead from Business Strategy
• Position project as business, not IT, initiative.
• Have a strong project leader: commitment of senior management.
• Get all affected parties to “buy in”.
• Communication within organization about expected change
• Re-engineer before the project: best practice processes
• Set customer’s expectations.
• The customer’s organization and culture.
• The risks presented by politics within the customer organization.
• What software package(s)?
• What consulting company?
• What hardware?
• What approach?
e.g Pasty Makers
• Pasty Makers– Finance system– Sales system– Warehouse system
• Problems– Supply Chain– Timely Information– Communication– Management Reporting– Manual Short-cuts– Forecasting
• Questions– Can I cut costs? How?– Can I improve efficiency?– How much does the process
cost?– When should I order?– What should I order?
• Integrated Database– Single GUI– Document creation– Data Protection
• Supply Chain integration– Triggered by orders– Minimises inventory
• Defined Reporting– Linked to strategy– Order tracking– BPI & costing
• Automated Processes– Ordering– Credit checks– Database management– Billing & Payment

6. Critical Views on ERP
Issues with ERP I• Considerable rate of failure in ERP implementation (study by Buckhout)
– 49% of respondents say SAP implementations are never complete
– Average schedule overrun 230%
– Desired functionality 59% below expectations
– Only 10% on projects finished on time
– 35% of projects cancelled
• Maintainance
– In most companies, maintenance of existing systems is at least 70% of application development budget
– Typically 80% of maintainance requests for enhancements
– Maintenance programmers are difficult to find
• Lack of Flexibility
– Difficult to modify processes (electronic concrete)
– Over-reliance on consultants
– Upgrade issues
Issues with ERP II• Technical problems
– ERP software configuration
– Integrating ERP software with hardware, telecommunications, and database software. Rare to have total integration.
– Need for periodic upgrades
• Human, social and political problems
– Inappropriate expectations for software
– Failure to specify strategic objectives
– Inadequate project championship or project management
– Lack of cross-functional approach to implementation
– Need to adopt built-in business processes
– No sensitivity to culture, structure, end-users
– Inadequate resources for training
Cost of ERP• Large company
– $50-500 Million– $30 million in software– $200 million in consulting– $ millions for hardware– Implementation: 4-6 years
• Medium sized companies– $10-20 million– 2 year implementation
• Cost break-up (rule of thumb)– Software – 10%– Hardware – 10%– Change management/training – 15%– BPR – 15%– Severance / re-educating / re-skilling – 20%– Consulting – 30%
Critical examination• Contextualist Critique
– What is a business process (practice?)
– Logical work v actual work
– Is radical possible?
– What is lost / gained (ST vs LT)
– Organisation usually conforms to the software
• Political critique
– Whose interests are being served?
– Often known as a cover for redundancies
– Work deskilling & intensification
– Commodotisation of employee knowledge
– Definition of “known”
– A political project? (surveillance + control)
• Ethical critique
– Sharing of personal information globally
e.g. Cisco
Source: Cisco ERP steering Committee Report, October 20, 1994
Cisco’s total ERP implementation costs = US$15 million
Hardware32%
Headcount14%

One Size Fits All?
• Global Supply Chains = Supply chains that involve suppliers and/or customers in other countries. Some of the issues involved in global supply chains;
– legal issues, customs fees and taxes
– language and cultural differences
– fast changes in currency exchange rates
– political instabilities
• Different company structures & cultures• Different local configurations• Cultural clash – 'open systems' ERP and 'closed systems'
organisation
e.g. SAP in Singaporean Hospitals
• Types of misfits
– Company-specific misfits
• System’s patient management module does not allow for billing individual patients on installment plan
– Public sector-specific misfits
• System uses internally generated patient ID, instead of government issued ID number
– Country-specific misfits
• Package did not provide reports needed for government reporting
• System requires names entered in Western name format (first, middle, last); operators had trouble parsing Indian, Malay and Chinese names
e.g British Airways – Virgin Atlantic
• Virgin rented space for a customer and sales database – from its key trans-Atlantic rival, BA
• There was a confidentiality agreement – Virgin's data is safe and secured
• But, BA broke the agreement, found the names & addresses of Virgin's top customers, and stole them – with special offers
• Virgin took BA to court – and won. BA forced to pay huge damages and suffered considerable loss of face/reputation
