Case how truserv planned its it
Case: How TruServ planned its IT


  • The merger of Cotter & Co. and TruServ in 1997 required combining the information systems of the two companies.


  • A strategic IT planwas created and addressed issues such as;

    • the company’s Intranet and extranet

    • e-procurement

    • EC applications


  • The plan has remained fluid. It has been reevaluated and updated with new business goals every six months since its inception.

It planning
IT Planning

IT planning is essential for both planners & end-users

for several reasons:

  • End-users do IT planning for their own units.

  • End-users must participate in the corporate IT planning and therefore must understand the process.

  • Corporate IT planning determines how the IT infrastructure will look. This in turn determines what applications end-users can deploy.

It planning cont

AStrategic information systems planidentifies a set of computer-based applications that will help a company reach its business goals.

IT planning identifies the applications portfolio, a list of major, approved IS projects that are consistent with the long-range plan.

Planning and control systems for IT started in the late 1950s and early 1960s.

Initial mechanisms addressed operationalplanning, and eventually shifted to managerialplanning.

IT Planning (cont.)

It planning issues

Aligning the IT plan with the organizational business plan

Designing an IT architecture for the organization in such a way that users, applications, and databases can be integrated and networked together.

Efficiently allocating information systems development and operational resources among competing applications.

4. Planning information systems projects so that they are completed on time and within budget and include the specified functionalities.

IT Planning Issues

Basic IT planning addresses the following four general issues:

Stage 1 strategic information planning
Stage 1: Strategic Information Planning

  • Strategic information planning (SIP) must be aligned with overall organizational planning and with e-business.

  • To accomplish this alignment, the organization must execute the following:

    • Set the IT mission.

    • Assess the environment.

    • Assess existing systems’ availabilities and capabilities.

    • Assess organizational objectives and strategies.

    • Set IT objectives, strategies, and policies.

    • Assess the potential impacts of IT.

  • An organization would conduct the same six steps for e-business.

Business systems planning
Business Systems Planning

  • The Business systems planning (BSP) model, developed by IBM, is a top-down approach that starts with business strategies.

  • It deals with two main building blocks as the basis of the information architecture;

    • Business processes

    • Data classes

  • The recognition that processescould be a more fundamental aspect of business than departments or other organizational arrangements broke new ground.

Csf scenario planning
CSF & Scenario Planning

  • The critical success factors (CSF) approach was developed to help identify the information needs of managers.

    • Sample questions asked in the CSF approach are:

      • What objectives are central to your organization?

      • What are the critical factors that are essential to meeting these objectives?

      • What decisions or actions are key to these critical factors?

      • What variables underlie these decisions, and how are they measured?

  • Scenario planning is a methodology used in planning situations that involve much uncertainty, like that of IT in general and e-commerce.

    • In this approach planners create several scenarios.

Stage 2 information requirements analysis
Stage 2: Information Requirements Analysis

Step 1: Define underlying organizational subsystems.

Step 2: Develop subsystem matrix.

Step 3: Define and evaluate information requirements for organizational subsystems.

Step 4: Define major information categories and map interview results into them.

Step 5: Develop information/subsystem matrix.

Stage 3 resource allocation
Stage 3: Resource Allocation

  • Resource allocationconsists of developing the hardware, software, data communications, facilities, personnel, and financial plans needed to execute the master development plan defined in Stage 2.

  • This stage provides the framework for technology and labor procurement, and identifies the financial resources needed to provide appropriate service levels to users.

  • Funding requests from the ISD fall into two categories;

    • Those necessary to stay in business

    • Those for improving the information architecture

Stage 4 project planning
Stage 4: Project Planning

  • Project Planningprovides an overall framework within which specific applications can be planned, scheduled, and controlled.

  • This stage is associated with systems development (to be covered in Chapter 14).

Infrastructure considerations
Infrastructure Considerations

  • Broadbent et al. (1996) found the following four infrastructure relationships;

    • Industry—manufacturing firms use less IT infrastructure services than retail or financial firms.

    • Market volatility—firms that need to change products quickly use more IT infrastructure services.

    • Business unit synergy—firms that emphasize synergies (e.g., cross-selling) use more IT infrastructure services.

    • Strategy and planning—firms that integrate IT and organizational planning, use more IT infrastructure services.

It architecture computing
IT Architecture Computing

  • Centralized computingputs all processing and control authority within one computer and all other computing devices respond.

  • Distributed Computinghandles the choices for computing at the point of the computing need; individual needs are met with individualized computing.

  • A Blended approachcombines the two models above. The mainframe (centralized resource) can operate as a peripheral device for other (distributed) computing resources.

Reengineering legacy systems
Reengineering Legacy Systems

  • Legacy Systems are holdovers of earlier architectures that are still in use after an organization migrates to a new architecture.

    • The decision—to keep, improve, or replace—can present management with agonizing alternatives.

  • Reverse engineering is the process of examining systems to determine their present status, and to identify what changes are necessary to allow the system to meet current and future business needs.

It planning e planning
IT Planning & E-Planning

Some connections between IT planning and e-planning are:

  • Web applications may replace traditional IT applications for improving their operations.

  • Web applications must be integrated with legacy systems, ERP, etc.

  • The e-Commerce unit may report to the CIO.

  • The ISD and the e-Commerce project may compete for limited resources.

  • Some Web-based applications are designed to directly support the IT strategy and goals.

Applications portfolio
Applications Portfolio

  • Tjan’s Portfolio Strategy.Tjan (2001) adopted a business project portfolio applications approach to create an Internet portfolio planning.

    • The strategy is based on company fit,which can be either low or high, and the project’sviability, which can also be low or high.

    • The various initiatives are then mapped on the Internet portfolio matrix, based on the two average scores.

    • If bothviability and fit are low, the project is killed. If both are high, then the project is adopted, etc.

Issues in e planning
Issues in E-Planning

  • Who and where?Should the EC initiatives be conducted in a completely independent division or even a separate company?

  • Use of metrics.It is desirable to use industry standards, also known as metrics, for executing various steps of the planning process.

  • Learn from failures. During 2000/2001 there were many EC failures, both major initiatives and whole companies.

  • Use a different planning process. The Web environment requires a different planning process.

  • Integration. Information systems strategic planning must integrate, in many cases, e-business and knowledge management.

Business process reengineering
Business Process Reengineering

  • Business process reengineering (BPR) refers to a situation in which an organization fundamentally and radically redesigns its business process to achieve dramatic improvement.

    • Initially, attention was given to a complete restructuring of organizations.

    • Later, the concept was changed due to failures of BPR projects and the emergence of Web-based applications.

    • Today, BPR can focus on anything from the complete restructuring of an organization to the redesigning of individual processes.

    • Major objective of BPR = Information Integration.

Case vw of mexico uses e procurement
Case: VW of Mexico uses e-Procurement


  • Facing strong competition and the North American Free Trade Agreement (NAFTA) environment, Volkswagen of Mexico turned to IT.


  • In 1996 VW implemented an enterprise resource planning system, using SAP R/3 software.

  • By 1998, the company integrated its entire enterprise system.


  • The company projects that its IT applications will result in $50 million in cost savings over three years for the dealers.

Mass customization

One of the most successful models of e-Commerce ismass customization.

the production of large quantities of customized items.

It supplements or even replaces one of the most innovative concepts of the Industrial Revolution,mass production.

Mass customization can be facilitated by the Web in four different approaches;

Collaborative customizers

Adaptive customizers

Cosmetic customizers

Transparent customizers

Mass Customization

Mass customization ec
Mass Customization & EC

  • EC transforms the supply chain from a traditional push model to a pull model.

    • Push model - the business process starts with manufacturing and ends with consumers buying the products or services.

    • Pull model - the process starts with the consumer ordering the product (or service) and ends with the manufacturer making it.

  • The pull model enables customization since orders are taken first.

Cycle time reduction
Cycle Time Reduction

  • IT helps to contribute to cycle time reduction.

  • Cycle time refers to the time it takes to complete a process from beginning to end.

  • Time is recognized as a major element that provides competitive advantage.

Bpr failures
BPR Failures

  • During the 1990s there were just as many cases of BPR failures as there were success stories.

  • A survey conducted by the PROSCI organization ( indicates a failure rate of 50 to 80%.

  • Some of the reasons cited for failures are:

    • high risk

    • inappropriate change management

    • failure to plan for internal politics

    • high cost of retooling

    • lack of participation and leadership

    • inflexible software

    • lack of motivation

Networked organizations
Networked Organizations

  • Today some organizations are turning away from the hierarchical organization toward the networked organization.

    • Networked organizationsrefer to organizational structures that resemble computer networks and are supported by information systems.

  • In the information-based economy, most people do knowledgework, and the subordinate often has more expertise than the “hierarchical” supervisor.

  • A flattened organizationhas fewer layers of management and a broader span of control than the hierarchical organization.

Empowerment using it
Empowerment Using IT

  • Empowermentis the vesting of decision-making or approval authority in employees where, traditionally, such authority was a managerial prerogative.

  • Empowerment can be enhanced through IT.

    • Empowered employees are expected to perform better.

  • In addition to empowering employees, companies are empowering their customers, suppliers, and other business partners.

    • E.g. Federal Express uses the Internet to empower its customers.

Virtual corporations
Virtual Corporations

  • A Virtual Corporation (VC) is an organization composed of several business partners sharing costs and resources for the purpose of producing a product or service.

  • According to Goldman et al. (1995), permanent virtual corporations are designed to do the following:

    • Create or assemble productive resources rapidly.

    • Create or assemble productive resources frequently and concurrently.

    • Create or assemble a broad range of productive resources.

Virtual corporations cont
Virtual Corporations (cont.)

  • In a VC, the resources of the business partners remain in their original locations but are integrated.

  • In order to function, VCs rely on the following forms of IT;

    • Communication/ collaboration among dispersed business partners

      • e.g., e-mail, desktop videoconferencing, screen-sharing, etc.

    • EDI and EFT

    • Intelligent agents

    • Modern database technologies and networking

    • Intranet/Internet applications

Managerial issues

Fitting the IT architecture to the organization is important.

Importance. IT planning is one of the most challenging and difficult tasks facing all of management.

Organizing for planning.What should be the role of the ISD? How should IT be organized? Staffed? Funded?

Managerial Issues

Managerial issues cont

IT architecture planning.IT specialists & business users must jointly determine the present and future needs for the IT architecture.

Ethical and legal issues.

IT policy.IT architectures should be based on corporate guidelines.

IT strategy. Leadership, listening and experimentation are important.

Integration. The role of IT in redesign and BPR.

Failures. Very big projects have a tendency to fail when expectations exceed real capabilities.
