However, there are vital rising concerns regarding the possible consequences of deploying artificial intelligence, sophisticated robotic technologies, automated vehicles, self-managing supply modes, and blockchain economies on business performance and culture, including how to sustain a supportive business culture and to what extent a strategic fit between human-robot collaboration in a business ecosystem can be created.
The Handbook of Research on Strategic Fit and Design in Business Ecosystems is a collection of innovative research that builds a futuristic view of evolving business ecosystems and a deeper understanding of business transformation processes in the new digital business era.
Featuring research on topics such as cultural hybridization, Industry 4. The study begins with a detailed examination of ERP features that highlights the advantages and disadvantages of ERP adoption.
Critical success factors for ERP implementation and post-implementation are then discussed, along with the capabilities of ERP in driving the alignment between management accounting and financial accounting information. Critical success factors for BI implementation are then presented, along with the BI maturity model and lifecycle. Such as Milpro. For example, eBay, the giant Web auction site.
Until recently almost all e-commerce transactions took place over wired networks. Now cell phones and other wireless handheld digital appliances are internet enabled so that they can be used to send t email or access websites. The use of handheld wireless devices for purchasing goods and services is called mobile commerce or m-commerce. Customer Centered Retailing 1. Direct Sales over the Web Manufacturers can sell their product and services directly to retail customers bypassing intermediaries such as distributor or retail outlets.
Eliminating intermediaries in the distribution channel can significantly lower purchase transaction cost. Operator of virtual storefront such as amazon. Airlines can ell tickets directly to passengers through their own websites or through without paying commission to travel agents. The removal of organizations or business process layers responsible for intermediary steps in a value chain is called disintermediation. The process of shifting the intermediary function in a value chain to a new source is called reinter mediation.
Fig:- Benefits of Direct sales over web 2. Interactive Marketing and personalization Marketers can use the interactive web pages to hold customers attention or to capture detail information about their taste and interest for one-to-one marketing. Some customer information may be obtained by asking visitors to register online and provide information about them but many companies are also collecting customer information by using software tools that track the activities of website visitors.
By using web personalization technology to modify the web pages presented to each customer , marketers can achieve the benefits of using individual sales peoples at dramatically lowers cost. Personalization can also help firms form lasting relationship with customers by providing individualized content. Customers Self Service Many companies are using their websites and email to answer customer question to provide customers with helpful information.
Automated self-service or other web based response to customer question cost a fraction of the price of using a customer service representation on the telephone. New products are even integrated the web with customer where customer services problems have been traditionally solved over the telephone.
How intranets support electronic business Intranets can help organizations create a richer, more responsive information environment. Internet corporate applications based on the web page model can be made interactive using a Santosh Dhungana MIS Version 1. A principle use of intranets has been to create online repositories of information that can be updated as often as required.
Organizational benefits of intranet:- 1. Connectively: Accessible from most computing platforms. Can be tied to internal corporate systems and core transactions database. Can create interactive applications with text, audio and video. Easy to use, universal web interface. Low start-up cost. Richer, more responsible information environment. Reduced information distribution cost.
Chapter 5 Redesigning the organization with information system 5. IT also includes changes in jobs skills management and organization. In the socio technical philosophy, one cannot install new technology without considering the people who must work with it.
When we design a new information system, we are re- designing organization. One important thing to know about building a new information system is that this process is one kind of planned organizational change.
System builders must understand how a system will affect the organization as a whole, focusing particularly the organizational conflict and changes in the locus of decision making. Managers must also consider how the nature of work group will change under the new system.
Systems can be technical successes but organizational failure because of a failure in the social and political process of building the system.
Analyst and designer are responsible for ensuring that key participants members of the organization participate in the design process are permitted to influence the system ultimate shape. Organization need to develop an information systems plan that supports their overall business plan. One specific project have been selected within the overall context of a strategic plan for the nosiness and the systems area, an information system plan can be developed.
The plan serves as road map indicating the direction of systems development, the rationale, the current situation, the management strategy, the implementation plan, and the budget. How to develop an Information System Plan A good information system plan should address the following topics 1. Current systems i. Major system supporting business functions and processes ii.
Current infrastructure capabilities - Hardware, software - Database iii. Difficulties meeting business requirements iv. Anticipated future demands 4. New developments i. New system projects - Project descriptions and business rationale ii.
New infrastructure capabilities required - Hardware, software - Database - Telecommunication and Internet 5.
Management strategy i. Acquisition plans ii. Milestone and timing iii. Organizational realignment iv. Internal reorganization v. Management controls vi. Major training initiatives vii.
Personal strategy 6. Implementation plan i. Anticipated difficulties in implementation ii. Progress plan 7.
Budget requirement i. Requirements ii. Potential savings iii. Financing iv. Acquisition cycle 5. Two principal methodologies for establishing the essential information requirements of the organization as whole are enterprise analysis and success factors. Enterprise Analysis Business Systems Planning Enterprise analysis argues that the firm's information requirements can only be understood by looking at the entire organization units, functions, processes, and data Santosh Dhungana MIS Version 1.
Enterprise analysis can help identify the key entities and attributes of the organization's data. The central method used in the enterprise analysis approach is to take a large sample of managers and ask them how they use information, where they get their information, what their environments are like, what their objectives are, how they make decision, and what their data needs are, and how they make decision and what their data needs are. The results of these large surveys of managers are aggregated into sub units, functions, processes and data matrices.
Data elements are organized into logical application groups- groups of data elements that support related sets of organizational processes. The weakness of enterprise analysis is that it produces an enormous amount of data i. Most of the interviews are conducted with senior or middle managers, but there is little effort to collect information from clerical workers and supervisory managers.
CSFs are shaped by the industry, the firm, the manager and the broader environment. An important premise of the strategic analysis approach is that there are a small number of objectives that managers can easily identify and on which information systems can focus. The principle methods used in CSFs analysis is personal interviews 3 or 4 with a number of top manager to identify their goals and resulting CSFs.
Then systems are built to develop and deliver information of these CSFs. The strength of the CSFs method is that it produces a smaller data sat to analyze then enterprise analyze analysis. Only top managers are interviewed and the questions focus on the small number of CSFs rather than a broad enquiry into what information is used or needed.
The CSFs method takes into account the changing environment with which organizations and managers must deal. Unlike enterprise analysis, the CSFs method of focuses organizational attention how information should be handed.
Small of these system projects represents radical restructuring of their business processes, whereas others entail more incremental change. This restructuring of their business processes is called business process re-engineering eliminating repetitive tasks. Work flow management:- The process of stream lining business procedures so that documents can e moved easily and efficiently is called workflow management.
Steps in Effective Re-engineering - Senior management needs to develop a broad strategic vision that calls for re- designing business processes. Eg: if the objective of process redesign is to reduce time and cost in developing a new product or finding an order, the organization needs to measure the time and cost consumed by the unchanged process. Following these steps it does not automatically guaranteed that re-engineering will always be successful.
Fear of changes develops resistance, confusion and even conscious to undermine the change effort. The scope of re-engineering projects had widened, adding to their complexity. TQM Total Quality Management A concept that makes quality control a responsibility to be shared by all people in an organization. Sin Sigma A specific measure of quality, representing 3. How the IS support quality improvements???? Simplifying the product r the production process. Benchmarking: setting strict standards for products, services or activities and measuring organizational performance against those standards.
Use customer demands as a guide to improve products and services. Reduce cycle time. Improve the quality and precision of the design 6. Increase the precision of production. System development The activities that go into producing an information systems solution to an organizational problem or opportunity are called system development.
These activities consist of system analysis, system design, programming, testing, conversion and production and maintenance. These activities usually take place in a sequential order. But some of the activities may need to be repeated or some may to taking place simultaneously depending on approach to system building i.
Note that each activities interaction with the organization. Systems Analysis System analysis is the analysis of the problem that the organization will try to solve with an information system. It consists of defining the problem, identifying it caused, specifying the solution, and identifying the information requirements that must be met by system solution. Generally it is the role of a system analyst to perform these jobs. The system analysis creates a road map of the existing organization and systems, identifying the primary owner and users of data in the organization.
In addition to these organizational aspects, the analyst also briefly describes the existing hardware and software that serve the organization.
Feasibility study The system analysis would include a feasibility study to determine whether that solution was feasible, or achievable, from a financial, technical and organizational stand point. Normally the system analysis processes will identify several alternative solutions that the organization can pursue. Information Requirements A detailed statement of the information needs that a new system must specify; identifies who needs that information, when that information is needed, where and how the information is needed.
System Design It is a detail of how a system will meet information requirements as determined by the system analysis. Like blueprints of a building or house, it consists of all the specifications. Programming The process of translating the system specifications prepared during the design stage into program code. Testing The exhaustive and through process that determines whether the system produces the desired results under know conditions.
Sometimes called program testing. Unit testing in multiple units results integration test. Alpha test abd Beta test encomprise acceptance test. Conversion Conversion is the process of changing form the old system to the new system. Four main conversion strategies be employed: the parallel strategy, the direct cutover strategy, the pilot study strategy, and the phased approach strategy.
Production and Maintenance After the new system is installed and conversion is complete, the system is said to be in production. During this stage the system will be reviewed by both user and technical specialists to determine how well it has met its original objectives and decide whether any revisions or modifications are in order. Changes in hardware, software, documentation, or procedures to production system to correct errors, meet new requirements, or improve processing efficiency are termed maintenance.
The introduction of new information technology has a ripple of effect, raising new ethical, social and political issues that must be dealt with on the individual, social and political lavels. Information technology and information systems raise new ethical questions for both individuals and societies because they create opportunities for intense social change and thus threaten existing distributions of power, money, rights, and obligations.
Like other technology such as steam engines, electricity, telephone and radio, IT can be used to commit crimes and threaten social values. The development of information technology will produce benefits for many and costs for others. So ethical and socially responsible course of actions should be understood and identify for using information systems.
Its relation can be shown as above diagram. The relation is the result of ripple effect. From ethical issues social issues are generated which in terms generates political issues. What information rights do individuals and organizations posses with respect to information about them self?
What can they protect? Accountability and Control Who can and will be held accountable and liable for the harm done to individual and collective information and property rights?
System Quality What values and system quality as well as standards of data should we demand to protect individual rights and the safety of society? Quality of Life What values should be preserved in information and knowledge based society?
What institution should we protect from violation? What cultural values and practices are supported by the new information technology? Trend Impact 1 Computing power double every 18 months More organization depends on computer system for critical operations. Responsibility: Accepting the potentials costs, duties and obligation for the decision one works. Accountability The mechanism for accessing responsibility for decision mode and action taken.
Liability The existence of laws that permit individual to recover this damage done to them by other actors, systems or organizations. Identify and describe clearly the facts.
