This chart depicts the history of information systems beginning with calculation systems, moving to functional systems that served a single department or function, and ending with integrated systems that span an entire organization.

Q1 – What are the differences between functional and cross-functional systems? Many companies are moving to integrated, cross-functional systems that integrate activities of an entire business process, like a customer order. This type of system may also be called a process-based system Most organizations use a mixture of old-styled functional systems and newer, integrated systems. © Pearson Prentice Hall 2009

Q3 – What are the functions of the five basic functional systems? It’s important to understand that a functional application is a computer program with features and functions to support a particular business activity. A functional system, on the other hand, is a complete information system that uses five components—hardware, software, data, procedures, and people. © Pearson Prentice Hall 2009

Q5 – What is business process design? Companies are redesigning their business processes to take advantage of cross-functional information systems. They are taking advantage of activity linkages and integrating activities in what’s called business process design, sometimes called redesign. There are a lot of challenges in designing and redesigning business processes. It’s expensive, time consuming, and difficult to keep up with normal business activities. Employees resist the changes in work responsibilities and normal habits. The ultimate outcome is always uncertain. Will the new processes work better than the old ones? © Pearson Prentice Hall 2009

Q5 – What is business process design? Inherent processes built into business process design software require an organization to conform its activities to the program. That can save a company substantial design costs. Inherent processes can also cause disruptions to operations and employees. This figure provides an example of inherent processes in an ordering process. Fig 7-15 Example of SAP R/3 Ordering Process © Pearson Prentice Hall 2009

A Customer Relationship Management (CRM) system offers these benefits: Q6 – What are the functions and characteristics of the three major cross-functional systems? There are three major cross-functional systems: customer relationship management, enterprise resource planning, and enterprise application integration. A Customer Relationship Management (CRM) system offers these benefits: Integration of primary business activities Tracking of all customer interactions Storage of customer data in single a database Support of customer life cycle. © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? Figure 7-16, to the top right, shows how a CRM system integrates the primary business activities in the value chain model. Figure 7-17, to the bottom right, depicts the four phases of the customer life cycle and shows how a CRM system integrates them into three major processes: solicitation, lead-tracking, and relationship management. © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? The chart below shows the major components of a Customer Relationship Management (CRM) system: solicitation, lead tracking (presale), and relationship management (post sale). Fig 7-18 CRM Components © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? Customer Relationship Management (CRM) systems store data in a single database and link CRM processes to one another. Fig 7-19 CRM Centered on Integrated Customer Database © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? The second type of cross-functional system is an Enterprise Resource Planning (ERP) System that provides more integration than a CRM by integrating primary value chain activities with human resources and accounting support activities across the enterprise.

The benefits of an ERP are presented in figure 7-22 below. Q6 – What are the functions and characteristics of the three major cross-functional systems? The characteristics of an ERP system are presented in figure 7-21 to the right. The benefits of an ERP are presented in figure 7-22 below. © Pearson Prentice Hall 2009

Here are the required tasks to implement an ERP system: Q6 – What are the functions and characteristics of the three major cross-functional systems? Here are the required tasks to implement an ERP system: determine current and ERP models remove inconsistencies implement the ERP system. Fig 7-23 ERP Implementation © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? An Enterprise Application Integration (EAI) System is the third type of cross-functional system. When an ERP system is inappropriate for an organization, it can still integrate its existing systems through layers of software that connect applications together. EAI systems enable a business’s existing applications to communicate and share data, providing many of the benefits of a cross-functional system without some of the disadvantages. A business can leverage its existing systems while enabling a gradual move to a more complicated ERP system. © Pearson Prentice Hall 2009

Q6 – What are the functions and characteristics of the three major cross-functional systems? An EAI system doesn’t have a central database but uses metadata to provide the organization with a virtual integrated database as this figure shows. Fig 7-24 Enterprise Application Integration (EAI) Architecture © Pearson Prentice Hall 2009

The benefits an EAI offers to an organization include: Q6 – What are the functions and characteristics of the three major cross-functional systems? The benefits an EAI offers to an organization include: Lower costs to implement than a full ERP. Less disruption to operations and employees. Integration of selected parts of the organization. A step-wise implementation process that allows the business eventually to achieve the full benefits of an ERP. The steps for an EAI system implementation include: Identifying sources of major isolation problems. Specifying the scope of the EAI implementation. Developing and implementing selected EAI systems. Assessing the benefits of EAI. Stopping further EAI development, expanding EAI efforts, or switching to ERP. © Pearson Prentice Hall 2009
