CHAPTER 1 Introduction to Enterprise Systems for Management
Learning Objectives • Understand the information systems evolution and its historical role in the organization leading to systems integration and Enterprise Resource Planning (ERP). • Learn about ERP systems and evolution, components, and architecture; understand the benefits and drawbacks of implementingERPsystems • Gain an overview of the implementation process (e.g., the ERP life cycle, businessprocessreengineeringprojectmanagement, and change management). • Comprehend the ethical, global, and securitychallenges while implementing an ERP system, and look at the ERP vendors and industry trends.
Preview • In the early days of ERPimplementation most management did not understand the amountof issues an organization has to consider before, during, and after implementation. • ERP systems are very different from regular packaged software, such as Microsoft Office and others. • There are no shortcuts when it comes to implementing an enterprise system.
Information Systems in Organizations • Before looking into the details of ERP systems, we will review the evolution of InformationSystems in organizations. • Information Systems are a critical component of a successful organization today. • Information Systems provide a highlevel of computerautomation to support business functions such as: • Accounting • Finance • Marketing • Customer Service • Human Resource Management • Business Operations • Information Systems play a major role in primary and secondary activities of an organization’s value chain.
Information Systems in Organizations (Cont’d) • Information systems include hardware, software, communication, dataprocesses, and people. • Information Technology includes only the hardware and software components. • The role of an information system is to processdata into information using information technology, business processes, and people resources.
Information Systems in Organizations (Cont’d) • Information Technology is thus a component of Information Systems. • Information systems generally use a three-phased model of input, process, and output. • A combination of the five information system components is used during each of the phases. For example, during input and output phases people are utilized highly, whereas information technology and business processes rules are predominantly used through the process phase.
Role of Information Systems in the Enterprise • Business organizations have become more complex due to • increased layer of management hierarchyand • increased level of coordination across departments. • Each department has different information needs. • No single information system can support all the business needs of an organization. • Management is generally categorized into three levels- Strategic, Middle, and Operational. • Each management level has different information requirements.
Management Pyramid with Information Requirements • Strategic level: • Functions are highly unstructured, and resources are undefined • Less quantitative requirements • Operational Level: • Functions are highly structured, and resources are predefined • quantitative requirements are more • Mid-management Level: Somewhere in between • The CEO of a company may need (interest in) a report that quickly states how a particular product is performing in the market in different times and places (compared with other companies). Whereas operational management interest in detailed sales report of all products that he/she responsible for last in the month.
Business Processes and Information Systems • Business process is a group of activities or tasks that are coordinated for achieving a business goal (e.g. fulfilling customer order, ordering supplies, targeting customer, designing new products, hiring employees, etc.). • Business processes refer to the manner in which • Work is organized, coordinated, and focused to produce a valuable product or service • Is a concrete workflowsofmaterial, information and knowledge (set of activities). • Ways in which organizations coordinatework, information and knowledge and the ways in which management chooses to coordinate work. • Every business can be seen as a collection of businessprocesses. • Many businessprocesses are tied to a specificfunctionalarea. For example sales and marketing area function would be responsible for identifying customers, and human resourcesfunction would be responsible for hiring employees.
Business Processes and Information Systems Other business processes cross many different functional areas and require coordination across departments. For example fulfilling customer order: First sales department would receive a sales order. The order will pass first to accounting to ensure the customer can pay for the order. Then, production department pull the product from inventory and finally product needs to be shipped. Can you provide other example Fulfilling a customer order involves a complex set of steps that requires the close coordination of the sales, accounting, and manufacturing functions.
Information Silos and Systems Integration • As organizations become larger and morecomplex, they tend to break functions into smallerunits by assigning a group of staff to specialize in these activities. • Over time, Information Systems create a mixture of independentnonintegratedsystems, which ultimately creating bottlenecks and interfering with productivity. • In today’s globally combative environment, an organization will find it difficult to operate and survive with siloinformationsystem • Organizationsneed to be agile and flexible and will require their information systems to haveintegrated data, applications, and resources from acrosstheorganization. • To compete effectively, organizations have to be customerfocused. • This requires cross-functional integration among the accounting, marketing and other departments of the organization.
Enterprise Resource Planning (ERP) Systems WHAT IS AN ERP SYSTEM? • Enterprise Resource Planning Systems are the first generation of enterprise systems meant to integrate dataacross and support all the major functions of the organization. • ERP systems integratevarious functional aspects of the organization as well as the systems within the organization with those of its partners and suppliers. • These systems are web enabled, means, that they work using web clients, making them accessible to all of the organization's employees, client, partners and vendors from anytime and anyplace. • The goal of an ERP system is to make the information flowdynamic and immediate, therefore, increasing its usefulness and value of information.
Enterprise Resource Planning (ERP) Systems (Cont’d) • ERP acting as a central repositoryeliminatingdataredundancy and addingflexibility. • Another goal of ERP is to integratedepartments and functionsacross an organization onto a singleinfrastructure that serves the need of each department. • Each department has its own computer system. ERP combines them all together into a single integratedsoftwarethat work on a singledatabase, thereby allowing various department to share information and communicate with each other more easily. • ERP systems replace a variety of systems that typically existed in organizations. • Moreover, ERP solves critical problem of integrating information from different sources and makes it available in real-time.
ERP Systems Components • An ERP system consists of: • To perform input, processing and output phases of a system. • The implementation team must carefully evaluate each components in relation to others while developing an implementation plan.
ERP Components • These components must work together seamlessly for the implementation to be successful. • Hardware, software and data play a significantrole in an ERP system implementation. • People involvement and process integration needs to be addressed from the veryearlystages in the implementation plan.
ERP Components Integration • Each component must be layered appropriately and each layer must support the efficiency of the otherlayers. • The layered approach also provides the ability to change layers without significantly affecting the other layers.
ERP Architecture • The architecture of an ERPsystem influences the cost, maintenance, and the use of the system. • The ERP architecture (blueprint of the actual ERP system) helps the implementation team build the ERP system for the organization. It transforms the high level ERPimplementation strategy into information flow with interrelationships in the organization. • If purchased, ERP architecture is often driven by the vendor (Package-Driven Architecture). Not like IT architecture, in which architecture is driven by organizational strategy. • There are two types of architectures. • Logical focuses on the supporting needs of the endusers. • Physical focuses on the efficiency of the system.
Logical Architecture of an ERP System • The logicalarchitectureprovides database schemas of the entities and relationships at the lower tier, followed by • The core business processes and business logic handled by the system at the second tier. • The third tier provides the details on the applications that support the various business functions built in the ERP system. • The end users do not ever see the first and second tiers because they interact primarily with the client user interface application tier that provides them access to the functional application.
Physical focuses Architecture: Tiered Architecture Example of ERP System
E-Business and ERP • Since the late 1990s, e-business and ERP have emerged as complementary technologies, rather than the competing technologies.
System Benefits of an ERP System • Integration of data and applications across functional areas (i.e., data can be entered once and used by all applications; thus improving accuracy and quality of the data). • Improvements in maintenance and support as IT staff is centralized. • Consistency of the userinterface across various applications means less employee training, better productivity, and cross-functional job movements. • Securityofdata and applications is enhanced due to better controls and centralizationofhardware.
System Limitations of an ERP System • Complexity of installing, configuring, and maintaining the system increases, thus requiring specialized IT staff, hardware, and network facilities. • Consolidation of IThardware, software, and people resources can be cumbersome and difficult to attain. • Data conversion and transformation from an old system to a new one can be tedious and complexprocess. • Retraining of ITstaff and endusers of the new system can produce resistance and reduce productivity.
Business Benefits of an ERP System • Agilityoftheorganization in terms of responding to changes in environment for growth and maintaining market share • Sharing of informationacrossfunctional areas helps collaboration between employees. • Linking and exchanging information in real-time with supply-chain partners improves efficiency leading to lower costs. • Bettercustomerservice due to quicker information flow across departments. • Efficiency of business processes are enhanced due to the re-engineering of business processes.
Business Limitations of an ERP System • Retraining of all employees with the new system can be costly and time consuming. • Change of businessroles and departmentboundaries can create upheaval and resistance to the new system.
ERP Implementation • ERP systemscontinuously changing and evolvingto provide the organization with anew way of looking at business processes and Decision making. Organizations are also continuously changing to match their environment. Both needs flexibility to adapt with each other. • Before implementing ERP, an organization has to plan and understandthe ERP life cycle. • The key for a successful implementation is to use a proven methodology, take it one step at a time, and begin with an understanding of the ERP life cycle. With no methodology, deadline will likely be missed, budgetoverspent, and functionalitywillnotmeet the client’s needs. • ERP system implementations are very risky, and using a well-defined project plan with a proven methodology will assist in managing those risks. • There must be a strong well-communicatedneed to make the change from the existing information systems/applications to an ERP system before starting any ERP implementation. Clear businessobjectives.
ERP Implementation Methodology • The projectmethodology needs to be documented, reviewed and fully understood by everyone involved in the project once objectives are outlined. • This is a sample ERP implementation methodology.
Product Life Cycle • Implementing ERP system require considering current business processand changes to those processes based on the functionality of the new system. If Business processes are not organized and compared with what the new system can do, it is very likely require significant modification after implementation. • In developing the business case for an ERP implementation one must make a decision on the number of modification to be made to address business requirements. • Chocolate implementation: Considerablemodifications to the ERP software package based on user requirements. • Vanilla implementation: Most purchased ERP systems today are minimally modified, to protect the investment in the system.
Software and Vendor Selection • It is best for an organization that does not have the experience in developing ERP systems to purchase one on the market. • Before selecting a vendor, the organization must carefully evaluate its current and futureneeds in enterprise management systems. This can start by looking at the size of organization, looking at the industry that the organization belongs to and the functional areas that the ERP application will be supporting. • Review the organization’s existing hardware, network, and software infrastructure, and the resources (money and people) available for the implementation is a key point.
Vendor Evaluation In addition, vendors need to be evaluated for the following: • Business functions or modules supported by their software • Features and integration capabilities of the software • Financialviability of the vendor as well as lengthoftime they have been in business • Licensing and upgradepolicies • Customerservice and helpdesksupport • Totalcost of ownership • ITinfrastructure requirements • Third-partysoftware integration • Legacysystemssupport and integration • Consulting and training services • Futuregoals and plans for the short and long term These criteria should help narrow down the selection to one ERP vendor that best fit the organization.
Operations and Post-Implementation • Going live (“Go-live”) is one of the most critical points in a project’s success. • It is vital to focus the efforts of all project teams to ensure that tasks and activities are completed before going live. Five areas of stabilization are important: • Training for end-users • Reactivesupport (i.e., help desk for troubleshooting) • Auditingsupport to confirm dataquality and Datafix to resolve data migration and errors revealed by audits • Newfeatures and functionalities to support the evolvingneeds of the organization
People and Organization Project Management • For an ERP system to be implemented successfully, project management must provide strongleadership, a clear and understood implementation plan, and close monitoring of the budget. • Project management is the glue that holds the projecttogether. It must follow a process that leadsto sound decisionmaking and creates a high level of trust and accountability with all involved in implementation. • It is balance of triangle sides, so any change to one side will require a change to one or more sides • A key component to project management is to understand and communicate the ERPsystem applicationmanagementlifecycle. Consultants It is often the case for organizations without much ERP implementation experience to use implementation partners such as consultants.
People and Organization (Cont’d) Change Management CM Role is essential because it prepares for changes to how business is done. In implementing new systems, communicating, preparing, and settingexpectations is as important as providing training and support. Business Process Re-engineering Businessprocess is a group of activities or tasks that are coordinated for achieving a business goal (e.g. ordering supplies, targeting customer, designing new products, etc.). Business processes will need to be changed, adjusted, or adapted to the new system to use the functionality of an ERP system fully. Global, Ethical and Security Management Outsourcing overseas, ethical issues, and problems with system security have also attracted a lot of attention in ERP implementation.

Implications for Management • ERP systems implementation is a complex organizational activity. • It is important to evaluate and learn from the successes and failures. • ERP systems implementation requires strong project management oversight. • ERP systems provide improved and added functionality for an organization.
Summary • Whereas the risks for implementing an ERP are greater, the payoff is very high for organizations. • The integration of data helps an organization to better meet the demands of a fast and dynamic business world. • The use of ERP systems provides for integrated data and business processes, thereby creating opportunities for organizations to expand and change as their business changes.
Summary (Cont’d) • ERP components consist of hardware, software, information, process, and people to perform the fundamental phases of an information system: input, process, and output. • ERP system architecture is a blueprint of the actual ERP system. There are two types of architecture: physical and logical. • The selection of a system must be based on these needs and how well a vendor meets those needs now or in the future.
Summary (Cont’d) • To be successful in implementing an ERP system, an organization and its management must clearly understand the implementation process.
Review Questions • How is the role of ERP system different from traditional TPS, MIS, DSS, and others? Can an ERP system support all levels of management? • Discuss the evolution of information systems in an organization. How can the use of ERP systems remove information or functional silos in organizations? • From all the ERP components listed in the chapter, which component is most critical in the implementation process and why? • Discuss the role of ERP in organizations. Are ERP tools used for business process reengineering (BPR) or does BPR occur due to ERP implementation?
