3Historical Context of ERP
- Historically, companies created islands of
automation. A hodge-podge of various systems
that operated or managed various divergent
business processes. Sometimes these systems were
integrated with each other and sometimes they
werent. Sometimes they were loosely interfaced
and sometimes they were more tightly interfaced.
4Historical Context of ERP
- The total organizational costs of maintaining a
patchwork of redundant and overlapping systems
has grown over the years to the point where the
cost of maintaining these systems is greater than
installing a new system.
5Historical Context of ERP
- Analysts have speculated that widespread adoption
of the same ERP package by the firms in a single
industry (an observed phenomenon for
semi-conductor manufacturers) might lead to the
elimination of process innovation-based
competitive advantage (Davenport, 1998).
6Historical Context of ERP
- Most companies have failed to implement ERP
packages successfully or to realize the hoped-for
financial returns on their ERP investment. - Companies have had similar difficulties with each
new wave of information technology since the
first mainframe systems. It takes years to
realize some envisioned IT-enabled changes in
organizational processes and performance, and
there are many ways to fail along the way.
7ERP DEFINITION
- Enterprise systems are commercial software
packages that enable the integration of
transactions-oriented data and business processes
throughout an organization (and perhaps
eventually throughout the entire
inter-organizational supply chain). - Enterprise systems include ERP software and
related packages as advanced planning and
scheduling, sales force automation, customer
relationship management, product configuration.
8Characteristics of Enterprise Systems
- Integration seamless integration of all the
information flowing through a company financial
and accounting, human resource information,
supply chain information, and customer
information.
9Characteristics of Enterprise Systems
- Packages Enterprise systems are not developed in
house. - IS life cycle is different 1)mapping
organizational requirements to the processes and
terminology employed by the vendor and 2) making
informed choices about the parameter setting. - Organizations that purchase enterprise systems
enter into long-term relationships with vendors.
Organizations no longer control their own
destiny.
10Characteristics of Enterprise Systems
- Best Practices ERP vendors talk to many
different businesses within a given industry as
well as academics to determine the best and most
efficient way of accounting for various
transactions and managing different processes.
The result is claimed to be industry best
practices. - The general consensus is that business process
change adds considerably to the expense and risk
of an enterprise systems implementation. Some
organizations rebel against the inflexibility of
these imposed business practices.
11Characteristics of Enterprise Systems
- Some Assembly Required Only the software is
integrated, not the computing platform on which
it runs. Most companies have great difficulty
integrating their enterprise software with a
package of hardware, operating systems, database
management systems software, and
telecommunications suited to their specific
needs. - Interfaces to legacy systems
- Third-party bolt-on applications
- Best of Breed Strategy (American Standard,
Starbucks)
12Characteristics of Enterprise Systems
- Evolving Enterprise Systems are changing
rapidly. - Architecturally Mainframe, Client/Server,
Web-enabled, Object-oriented, Componentization
(Baan). - Functionally front-office (ie. sales
management), supply chain (advanced planning and
scheduling), data warehousing, specialized
vertical industry solutions, etc.
13Why all the fuss about ERP?
- Market statistics
- US ERP sales grew from under 1 billion in 1993
to 8 billion in 1998 (Dataquest, 14.5 billion
worldwide). - In 1998 US companies spent 80 billion on ERP
systems integration. - Industry analysts expect an average rate growth
of 37 per year for the next 5 years.
14Why all the fuss about ERP?
- Market statistics
- AMR estimates worldwide ERP software sales to
grow to 52 billion by 2002. - If systems integration costs stay constant firms
will be spending 552 billion by 2002. - Firms also spend about 15-20 annually to keep
ERP systems up to date.
15What is ERP offering?
- ERP is business process infrastructure
- ERP is a software mirror image of the major
business processes of a firm, such as customer
order fulfillment and manufacturing. - ERP software automates and integrates the basic
processes of a firm, from finance to the shop
floor, and eliminate complex, expensive links
between computer systems that were never meant to
talk to each other.
16What is ERP offering?
- ERP is business process infrastructure
- ERP provides enterprise wide business process,
information and data management - stream-line and standard business processes and
operating procedures - provide interorganizational collaboration
- intraorganizational information sharing
17What is ERP offering?
- ERP Business Technology architecture
- Business Process Workflow Management
- Functional Information Management
- Marketing, Operations, HRM, etc.
- Decision Support Models and Tools
- Data Management
18What is ERP Offering?

20Motivation for Implementing ERP
- Achieving and maintaining competitive advantage
requires better information management - Information Quality
- Information Reliability
- Information Access
- Information Sharing
21Motivation for Implementing ERP
- Firms View ERP As A System
- to provide better information management
- to transform the competitive space
- to transform relationships between
- their customers
- their suppliers
- their competitors
22Motivation for Implementing ERP - Competitive
Space
23Motivation for Implementing ERP
- FIRMS ACHIEVE COMPETITIVE ADVANTAGE BY
- Locking in customer and suppliers
- Locking out the competition
- Attracting away competitors customers by
- product functionality
- cost performance
- service, reliability and flexibility
- quality and innovation
- response time/ time-to-market
24Motivation for Implementing ERP
25Motivation for Implementing ERP-
(inter-organizational efficiency)
- Better Supply Chain Management
- Inbound Logistics
- Operations
- Outbound Logistics
- Marketing And Sales
- Service
- Disintermediation and Market Reach
- Online Store Front
- Internet Banking
- Allows an organization to Reengineer all their
processes.
26Reasons for Not Adopting Enterprise Systems
- Lack of Feature-Function Fit between a companys
needs and the packages available in the
marketplace. - Company growth, strategic flexibility or
decentralized decision-making style. Many ERP
systems are not easy to change once they are
configured and installed. - Availability of alternatives for increasing the
level of systems integration Data Warehousing
(Kraft, CapitalOne?), Middleware (Dell)
27Phases of ERP Implementation
- The Chartering Phase
- Comprises the decisions leading up to the funding
of an enterprise system. - Key Players Vendors, Consultants, Company
Executives, IT specialists. - Key Activities Build a business case for ERP,
Select a software package, Identify a project
manager, Approve a budget and schedule.
28Phases of ERP Implementation
- The Project Phase
- Comprises the activities performed to get the
system up and running in one or more
organizational units. - Key Players Project Manager, Project team
members, Internal IT specialists, Vendors, and
Consultants. - Key Activities Software configuration, system
integration, testing, data conversion, training,
and rollout.
29Phases of ERP Implementation
- The Shakedown Phase
- The organizations coming to grips with the ERP
System. Ends when normal operations have been
achieved. (Or they give up and pull the plug on
the system) - Key Players Project Manager, Project team
members, Operational Managers, and End users. - Key Activities Bug fixing and rework, system
performance tuning, retraining, staffing up to
handle temporary inefficiencies. This is the
phase in which the errors of prior phases are
felt. New errors can arise in this phase also.
30Phases of ERP Implementation
- The Onward and Upward Phase
- Continues from normal operation until the system
is replaced with an upgrade or a different
system. This is where the organization is able to
ascertain the benefits (if any) of its
investment. - Key Players Operational Managers, End-users, IT
support personnel (Vendors and consultants may be
involved upgrades) - Key Activities Continuous business improvement,
additional user skill building, post
implementation benefit assessment. Most of these
activities are not performed.
31Phases of ERP Implementation
- There are several possible outcomes for each
phase of the implementation. - Unresolved problems from one phase are inherited
by the next phase. - Just like the SDLC, the longer problems go
undetected and unresolved, the more expensive it
is to fix them.
32ERP Scope and Impacts
- The ERP phenomenon is all encompassing for
companies and their key business partners - Financial Costs and Risks
- Technical Issues
- Managerial Issues
- IT Adoption, use and Impacts
- Integration
- ERP systems have strong conceptual links with
every major information systems area.
33ERP Failure
- Standish Group Study of ERP Implementations
- 35 are Cancelled
- 55 overrun their budgets
- Less than 10 are on time and under budget.
34ERP Failure
- Standish Group Study of ERP Implementations
- Implementation Averages
- Cost 178 over budget
- Schedule 230 longer
- Functionality 59
- or the system will only perform 41 of the
functions it was intended to perform.
35Why Implementations Fail
- People Dont want the systems to succeed
- People are comfortable and dont see the need for
the new system. - People have unrealistic expectations of the new
system. - People dont understand the basic concepts of the
system. - The basic data is inaccurate.
- The system has technical difficulties.
36What is ERP Success?
- KPMG Management Consultings recent report
Profit-Focused Software Package Implementation
showed some worrying results. Eighty-nine
percent of respondent companies claimed that
their projects were successful, but only a
quarter had actually obtained and quantified all
the planned benefits. (KPMG, 1998)
37What is ERP Success?
- How do you measure success?
- What are we trying to achieve? Scope, Vision.
- Project Metrics.
- Early Operational Metrics.
- Longer Term Business Results.
38What is ERP Success?
- Success is multidimensional and relative to both
time and objectives. - What is success today may not be success in two
years. (Or 6 months) - An ERP system that gives competitive advantage
today may not do so when competitors catch up and
this large ERP system simply becomes a cost of
doing business. - Success is often judged relative to the
organizations unique goals for the system.
39Factors in ERP Success
- Factors External to an Organizations Control
- Starting conditions Competitive position,
industry, financial position, prior relevant
experience, size, structure, management systems. - These conditions may change over the course of
the implementation. - ERP Implementations are highly fluid and subject
to radical and unforeseen changes. - An organizations goals and plans for the ERP
system may not be realistic when viewed
objectively in light of their starting
conditions.
40Organizations Motivated Behavior
- An organizations goal-directed enterprise
systems behavior can be defined in four
categories - Goals Some goals are more conducive to success
than others. Some are too limited, some are too
unrealistic. - Plans The methodology is critical for success.
- Execution A good methodology does not guarantee
quality in execution of the plan. - Response to Unforeseen Problems Successfully
resolve problems changing goals, plans and
actions to ensure a favorable outcome.
