It is a significant fact that we are in the focal point of a deep-seated change in both technology and its application. Any institutions in our day expect to get more value from their investments in technology. In the “Post dearth era of calculation” the user-friendliness of dispensation power is not a check where cost of platform technology has become a minor factor in selecting among alternatives to build the business solution and as such the constraining factors are the managerial impact of reengineering the business process and the costs and time required for system development. Additionally, the need to re-educate personnel to the compulsory level of expertise can be an extremely expensive scheme. Open systems enable organizations to buy off-the-shelf solutions to business problems. Open systems standards set apart the design in which data is swapped, remote systems are accessed, and services are attracted. The receipt of open systems standards supports the creation of system architectures that can be built from technology components. These standards enable us, as follows:
• To build reusable class libraries to use in object-oriented design and development environments.
• To build functional products those interact with the same data which are bedded on object oriented as well as bedded on full integrity.
• To modify a correspondence at an individual desktop workstation to include data, addressing and graphics input from a word processor, a personal spreadsheet, a workgroup database, and an existing project host relevance to be propelled by electronic mail to someplace in the world.
It is worth mentioning that opposing to the claims of groups variety from the Open Software base to the user consortium Open User Recommended Solutions, open systems are not exclusively systems that conform to OSF UNIX specifications. The client/server model makes the enterprise available at the desk. It provides access to data that the previous architectures did not. Standards have been defined for client-server figuring. If these principles are understood and used, a society can rationally expect to buy solutions today that can grow with their business needs without the constant need to revise the solutions. Architectures based on open systems standards can be implemented throughout the world, as global systems become the norm for large organizations. While a supportable common platform on a global scale is far from standardized, it certainly is becoming much easier to accomplish. From the desktop, enterprise-wide applications are indistinguishable from workgroup and personal applications. Powerful enabling technologies with built-in conformance to open systems standards are evolving rapidly. Examples include object-oriented development, relational and object-oriented databases, multimedia, imaging, expert systems, geographic information systems, voice recognition and voice response, and text management. These technologies provide the opportunity to integrate their generic potential—with the particular necessities of a business—to create a cost-effective and personalized business solution. The client/server model provides the ideal platform with which to integrate these enabling technologies. Well-defined interface standards enable integration of products from several vendors to provide the right application solution. Enterprise systems are those that create and provide a shared information resource for the entire corporation. They do not imply centralized development and control, but they do treat information and technology as corporate resources. Enterprise network management requires all devices and applications in the enterprise computing environment to be visible and managed. This remains a major challenge as organizations move to distributed processing. Standards are defined and are being implemented within the client/server model. Client/server applications give greater viability to worker empowerment in a distributed organization than do today’s host-centered environments.
Prospects are accessible to society and populace who are equipped and capable to compete in the global market and there is no denying the fact that a competitive global economy will ensure obsolescence and obscurity to those who cannot or are unwilling to compete. All organizations must look for ways to demonstrate value. We are in conclusion bearing in mind that an enthusiasm has to rethink upon existing managerial structures and commerce in putting into practice. Organizations are aggressively downsizing even as they try to aggressively expand their revenue base. There is more willingness to continue improvement practices and programs to eliminate redundancy and increase effectiveness. Organizations are becoming market-driven while remaining true to their business vision. To be competitive in a global economy, organizations in developed economies must employ technology to gain the efficiencies necessary to offset their higher labor costs. Reengineering the business process to provide information and decision-making support at points of customer contact reduces the need for layers of decision-making management, improves responsiveness, and enhances customer service. Empowerment means that knowledge and responsibility are available to the employee at the point of customer contact. Empowerment will ensure that product and service problems and opportunities are identified and finalized. Client/server computing is the most effective source for the tools that empower employees with authority and responsibility. The following are some key drivers in organizational philosophy, policies, and practices. Competitiveness is forcing organizations to find new ways to manage their business, despite fewer personnel, more outsourcing, a market-driven orientation, and rapid product obsolescence. Technology can be the enabler of organizational nimbleness. To survive and prosper in a world where trade barriers are being eliminated, organizations must look for partnerships and processes that are not restrained by artificial borders. Quality, cost, product differentiation, and service are the new marketing priorities. Our information systems must support these priorities.
Contesting demands that information systems organizations justify their costs and it is evident that business are in the way to question the return on their existing investments and as such Centralized IS an operation in particular are under the microscope. Manufactured goods obsolescence has never been so vital a factor. Purchasers have more options and are more demanding. Technology must enable organizations to anticipate demand and meet it. Quality and flexibility require decisions to be made by individuals who are in touch with the customer. Many organizations are eliminating layers of middle management. Technology must provide the necessary information and support to this new structure. If a business is run from its distributed locations, the technology supporting these units must be as reliable as the existing central systems. Technology for remote management of the distributed technology is essential in order to use scarce expertise appropriately and to reduce costs. Each individual must have access to all information he or she has a “need and right” to access, without regard to where it is collected, determined, or located. We can use technology today to provide this “single-system image” of information at the desk, whatever the technology used to create it. Standardization has introduced many new suppliers and has dramatically reduced costs. Competition is driving innovation. Organizations must use architectures that take advantage of cost-effective offerings as they appear. Desktop workstations now provide the power and mainframe capacity that mainframes did only a few years ago. The challenge is to effectively use this power and capacity to create solutions to real business problems. Downsizing and empowerment require that the workgroup have access to information and work collectively. Decisions are being made in the workplace, not in the head office. Standards and new technologies enable workstation users to access information and systems without regard to location. Remote network management enables experts to provide support and central, system-like reliability to distributed systems. However, distributed systems are not transparent. Data access across a network often has unpredictable result sets; therefore, performance on existing networks is often inadequate, requiring a retooling of the existing network infrastructure to support the new data access environment.
Standards enable many new vendors to enter the market. With a common platform target, every product has the entire marketplace as a potential customer. With the high rate of introduction of products, it is certain that organizations will have to deal with multiple vendors. Only through a commitment to standards-based technology will the heterogeneous multiple vendor environment effectively service the buyer. Workstation power, workgroup empowerment, preservation of existing investments, remote network management, and market-driven business are the forces creating the need for client/server computing. The technology is here; what is missing is the expertise to effectively apply it. Organizational pressures to demonstrate value apply as much to the information systems functions as to any other element or operating unit of the business. This is a special challenge because most IS organizations have not previously experienced strong financial constraints, nor have they been measured for success using the same business justification “yardstick” as other value-creating units within the business enterprise. IS has not been under the microscope to prove that the role it plays truly adds value to the overall organization. In today’s world, organizations that cannot be seen to add value are either eliminated or outsourced. It has been found out on a survey that about 1000 companies, on average, spend 90 percent of IS dollars maintaining existing systems. Major business benefits, however, are available only from “new” systems. Dramatic reductions in the cost of technology help cost justify many systems. Organizations that adapt faster than their competitors demonstrate value and become the leaders in their marketplace. Products and services command a premium price when these organizations are “early to market.” As they become commodities, they attract only commodity prices. This is true of both commercial organizations wishing to be competitive in the market with their products and of service organizations wishing to demonstrate value within their department or government sector. “It only took God seven days to create the world because he didn’t have an existing environment to deal with.”3 Billions of dollars have been invested in corporate computing infrastructure and training. This investment must be fully used. Successful client/server solutions integrate with the existing applications and provide a gradual migration to the new platforms and business models.
To meet the goals of the 1990s, organizations are downsizing and eliminating middle-management positions. They want to transfer responsibility to empower the person closest to the customer to make decisions. Historically, computer systems have imposed the burden of data collection and maintenance on the front-line work force but have husbanded information in the head office to support decision making by middle management. Information must be made available to the data creators and maintainers by providing the connectivity and distributed management of enterprise databases and applications. The technology of client/server computing will support the movement of information processing to the direct creators and users of information. OLTP applications traditionally have been used in insurance, financial, government, and sales-related organizations. These applications are characterized by their need for highly reliable platforms that guarantee that transactions will be handled correctly, no data will be lost, and response times will be extremely low, and only authorized users will have access to an application. The IS industry understands OLTP in the traditional mainframe-centered platforms but not in the distributed client/server platforms. Organizations do (and will continue) to rely on technology to drive business. Much of the IS industry does not yet understand how to build mission-critical applications on client/server platforms. As organizations move to employee empowerment and workgroup computing, the desktop becomes the critical technology element running the business. Client/server applications and platforms must provide mainframe levels of reliability. Executive information systems provide a single-screen view of “how well we are doing” by comparing the mass of details contained in their current and historical enterprise databases with information obtained from outside sources about the economy and competition. As organizations enter into corporation with their customers and suppliers, the need to integrate with external systems becomes essential in order to capture the necessary information for an effective EIS. Organizations want to use the EIS data to make strategic decisions. The DSS should provide “what if” analyses to project the results of these decisions. Managers define expectations, and the local processing capability generates decision alerts when reality does not conform. This is the DSS of the client/server model. Information is now recognized as a corporate resource. To be truly effective, organizations must collect data at the source and distribute it, according to the requirements of “need and right to access,” throughout the organization. Workgroups will select the platforms that best meet their needs, and these platforms must integrate to support the enterprise solution. Systems built around open systems standards are essential for cost-effective integration. Los Angeles County issued a request for information stating simply that its goal was “to implement and operate a modern telecommunications network that creates a seamless utility for all County telecommunications applications from desktop to desktop. The United States government has initiated a project—the National Information Interchange that has the simple objective of “making the intellectual property of the United States available to all with a need and right to access.
“Computers will become a truly useful part of our society only when they are linked by an infrastructure like the highway system and the electric power grid, creating a new kind of free market for information services. The feature that makes the highway and electric power grids truly useful is their pervasiveness. Every home and office has ready access to these services; thus, they are used—without thought—in the normal course of living and working. This pervasive accessibility has emerged largely because of the adoption of standards for interconnection. If there were no standards for driving, imagine the confusion and danger. What if every wall plug were a different shape, or the power available on every plug were random? If using a service requires too much thought and attention, that service cannot become a default part of our living and working environment. “Imagine the United States without its highways. Our millions of cars, buses, and trucks driven in our own backyards and neighborhood parking lots, with occasional forays by the daring few along uncharted, unpredictable, and treacherous dirt roads, full of unspeakable terrors.”7 The parking lot analogy illustrated in Figure 1.1 represents the current information-processing environment in most organizations. It is easy and transparent to locate and use information on a local area network (LAN), but information located on another LAN is almost inaccessible. End-user access to enterprise data often is unavailable except for predefined information requests. Although computers—from mainframes to PCs—are numerous, powerful, flexible, and widely used, they are still used in relative isolation. When they communicate, they usually do so ineffectively, through arcane and arbitrary procedures. Information comes with many faces. As shown in Figure 1.2, it can take the form of text, drawings, music, speech, photographs, stock prices, invoices, software, live video, and many other entities. Yet once information is computerized, it becomes a deceptively uniform sequence of ones and zeros. The underlying infrastructure must be flexible in the way it transports these ones and zeros. To be truly effective besides routing these binaries to their destinations the infrastructure must be able to carry binaries with varying degrees of speed, accuracy, and security to accommodate different computer capabilities and needs.
Because computers are manufactured and sold by vendors with differing views on the most effective technology, they do not share common implementation concepts. Transporting ones and zeros around, however flexibly, isn’t enough. Computers based on different technologies cannot comprehend each other’s ones and zeros any more than people comprehend foreign languages. We therefore need to endow our IS organizations with a set of widely understood common information interchange conventions. Moreover, these conventions must be based on concepts that make life easier for humans, rather than for computer servants. Finally, the truly useful infrastructure must be equipped with “common servers”—computers that provide a few basic information services of wide interest, such as computerized white and yellow pages.  Read more...
