MIS AND DECISION MAKING PROCESS

MIS AND DECISION MAKING PROCESS

      MIS is a system providing management with accurate and timely information. Such information is necessary to facilitate the decision-making process and enable the organizations planning, control, and operational functions to be carried out effectively. MISs increase competitiveness of the firm by reducing cost and improving processing speed. The power of technology has transformed the role of information in a business firm. Now information has become recognized as the lifeblood of an organization and without information, the modern company is dead.

     MIS and its organizational subsystems contribute to the decision making process in many ways. Power has stated that making decisions is an important part of working in the business environment. Companies often make decisions regarding operational improvements or selecting new business opportunities for maximizing the company's profit. Companies develop a decision-making process based on individuals responsible for making decisions and the scope of the company's business operations. A useful tool for making business decisions is a management information system. Historically, MIS was a manual process used to gather information and funnel it to individuals responsible for making decisions.

 Figure 1 shows this understanding about information as data processed for a definite purpose.





     MIS is an organization – wide effort to provide decision making process information. The system is a formal commitment by executive to make the computer available to all managers. MIS sets the stage for accomplishments in the other area, which is DSS, the virtual office and knowledge based systems. The main idea behind MIS is to keep a continuous supply of information flowing to the management. Afterwards, by data and information gathered from MIS, decisions are made.

     MIS is useful in the area of decision making as it can monitor by itself disturbances in a system, determine a course of action and take action to get the system in control. It is also relevant in nonprogrammer decisions as it provides support by supplying information for the search, the analysis, the evaluation and the choice and implementation process of decision making. Adebayo (2007) stressed the need for MIS in decision making as it provides information that is needed for better decision making on the issues affecting the organization regarding human and material resources.
MIS may be viewed as a mean for transformation of data, which are used as information in decision-making processes.

     MIS differs from regular information systems. The primary objectives of these systems are to analyze other systems dealing with the operational activities in the organization. MIS is a subset of the overall planning and control activities covering the application of humans, technologies, and procedures of the organization. Within the field of scientific management, MIS is most of ten tailored to the automation or support of human decision making.







What is a LAN (Local Area Network) ?

Definition - What does Local Area Network (LAN) mean?
A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings.
A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines.

 Techopedia explains Local Area Network (LAN)
In the 1960s, large colleges and universities had the first local area networks (LAN). In the mid-1970s, Ethernet was developed by Xerox PARC (Xerox Palo Alto Research Center) and deployed in 1976. Chase Manhattan Bank in New York had the first commercial use of a LAN in December 1977. In the late 1970s and early 1980s, it was common to have tens or hundreds of individual computers located in the same site. Many users and administrators were attracted to the concept of multiple computers sharing expensive disk space and laser printers.

From the mid 1980s to through the 1990s, Novell's Netware dominated the LAN software market. Over time, competitors such as Microsoft came out with comparable products to the point where nowadays, local networking is considered base functionality for any operating system.


Hardware and Software in MIS

what is mainframe ?

What is mainframe ?

A data processing system employed mainly in large organizations for various applications, including bulk data processing, process control, industry and consumer statistics, enterprise resource planning, and financial transaction processing.

Mainframes use proprietary operating systems, most of which are based on Unix, and a growing number on Linux. Over the years they have evolved from being room-sized to networked configurations of workstations and servers that are an extremely competitive and cost effective platforms for e-commerce development and hosting. Mainframes are so called because the earliest ones were housed in large metal frames.

BUILDING INFORMATION SYSTEM

Building a new information system is one kind of planned organizational change. The introduction of a new information system involves much more than new hardware and software.
Systems Development And Organizational Change
Information technology can promote various degrees of organizational change, ranging from incremental to far-reaching. There are four kinds of structural organizational change that are enabled by information technology:
 
  1. automation - assist employees with performing their tasks more efficiently and effectively.
  2. rationalization - a deeper form of organizational change and one that follows quickly from early automation
  3. business process redesign - business processes are analyzed, simplified, and redesigned
  4. paradigm shifts - involves rethinking the nature of the business and the nature of organization. Each carries different risks and rewards.
Business Process Redesign
Business process managemet provides a variety of tools and methodologies to analyze existing processes, design new processes, and optimize those processes. It has to go through the following steps:
  1. Identify processes for change: managers need to detrmine what business processes are the most important and how improving these processes will help business performance.
  2. Analyze existing processes: existing business processes should be modeled and documented, noting inputs, outputs, resources, and the sequence of activities.
  3. Design the new process: once the existing process is mapped and measured in terms of time and cost, the process design team will try to improve the process by designing a new one. A new streamlined “to-be” process will be documented and modeled for comparison with the old process.
  4. Implement the new process: new information systems or enhancements to existing systems may have to be implemented to support the redesigned process.  
  5. Continuous measurement: once a process have been implemented and optimized, it needs to be continually measured because they may lose their effectiveness if the business experiences other changes or deteriorate over time as employees fall back on old methods.

Overview of Systems Development
The activities that go into producing an information system solution to an organizational problem or opportunity are called systems development. Systems development is a structured kind of problem solved with distinct activities such as analysis, systems design, programming, testing, conversion, and production and maintenance.
Systems Analysis – the analysis of a problem that a firm tries to solve with an information system. It also includes a feasibility study to determine whether that solution is feasible or achievable, from a financial, technical, and organizational standpoint.
Establishing Information Requirements – it carefully defines the objectives of the new or modified system and develops a detailed description of the functions that the new system must perform.
Fig. The Systems Development Process
Systems Design – shows how the system will fulfill this objective. The design of an information system is the overall plan or model for that system.
The Role of End Users – users must have sufficient control over the design process to ensure that the system reflects their business priorities and information needs, not the biases of the technical staff.
Completing The Systems Development Process
The remaining steps in the systems development process translate the solution specifications established during system analysis and design into a fully operational information system. They are
· Programming – system specifications that were prepared during the design stage are translated into software program code.
· Testing – conducted thoroughly to ascertain whether the system produces the right results.
· Conversion – the process of changing from the old system to the new system.
· Production and Maintenance – after the new system is installed and conversion is complete, the system is said to be in production. Changes in hardware, software, documentation, or procedures to a production system to correct errors, meet new requirements, or improve processing efficiency are termed maintenance.
Modeling And Designing Systems: Structured And Object-Oriented Methodologies
There are alternative methodologies for modeling and designing systems. Structured methodologies and object-oriented development are the most prominent.
Structured Methodologies
Structured methodologies have been used to document, analyze, and design information systems since the 1970s. It refers to the fact that the techniques are step by step, with each step building on the previous one. They are top-down, progressing from the highest, most abstract level to the lowest level of detail – from the general to the specific. Process specifications describe the transformation occurring within the lowest level of the data flow diagrams. They express logic for each process. The structure chart is a top-down chart, showing each level of design, its relationship to other levels, and its place in the overall design structure.
Fig. High-Level Structure Chart for a Payroll System
Object-Oriented Development
Object-oriented development addresses these issues. It uses the object as the basic unit of systems analysis and design. An object combines data and the specific processes that operate on those data.
Fig. Class And Inheritance
Computer-Aided Software Engineering
Computer-aided software engineering (CASE) – sometimes called computer-aided systems engineering, provides software tools to automate the methodologies we have just described to reduce the amount of repetitive work the developer needs to do. CASE tools also facilitate the creation of clear documentation and the coordination of team development efforts.





Alternative Systems-Building Approaches
Traditional Systems Life Cycle
The systems life cycle is the oldest method for building information systems. The life cycle methodology is a phased approach to building a system, dividing systems development into formal stages. The systems life cycle is still used for building large complex systems that require a rigorous and formal requirements analysis, predefined specifications, and tight controls over the system-building process.
Prototyping
Prototyping consists of building an experimental system rapidly and inexpensively for end users to evaluate. The prototype is a working version of an information system or part of the system, but it is meant to be only a preliminary model.
Steps in Prototyping
Step 1: Identify the user’s basic requirements.
Step 2: Develop an initial prototype.
Step 3: Use the prototype.
Step 4: Revise and enhance the prototype.
Fig. The Prototyping Process

End-User Development
Some types of information systems can be developed by end users with little or no formal assistance from technical specialists. This phenomenon is called end-user development. A series of software tools categorized as fourth-generation languages makes this possible. Fourth-generation languages are software tools that enable end users to create reports or develop software applications with minimal or no technical assistance. Query languages are software tools that provide immediate online answers to requests for information that are not predefined.

Application Development For the Digital Firm
In the digital firm environment, organizations need to be able to add, change, and retire their technology capabilities very rapidly to respond to new opportunities. Companies are starting to use shorter, more informal development processes that provide fast solutions.

Rapid Application Development (RAD)
The term rapid application development (RAD)is used to describe this process of creating workable systems in a very short period of time. RAD can include the use of visual programming and other tools for building graphical user interfaces, iterative prototyping of key system elements, the automation of program code generation, and close teamwork among end users and information systems specialists. Sometimes a technique called joint application design (JAD) is used to accelerate the generation of information requirements and to develop the initial systems design. Properly prepared and facilitated, JAD sessions can significantly speed up the design phase and involve users at an intense level. Agile development focuses on rapid delivery of working software by breaking a large project into a series of small subprojects that are completed in short periods of time using iteration and continuous feedback.

Component-based Development and Web Services
To further expedite software creation, groups of objects have been assembled to provide software components for common functions such as a graphical user interface or online ordering capability that can be combined to create large-scale business applications. This approach to software development is called component-based development, and it enables to a system to be built by assembling and integrating existing software components. Web servicescan provide significant cost savings in systems building while opening up new opportunities for collaboration with other companies.


E-COMMERCE :DIGITAL MARKET AND DIGITAL GOODS

E-commerce refers to the use of the Internet and the Web to transact business. More formally, e-commerce is about digitally enabled commercial transactions between and among organizations and individuals. For the most part, this means transactions that occur over the Internet and the Web. Commercial transactions involve the exchange of value (e.g. money) across organizational or individual boundaries in return for products and services.

Fig. The Growth Of E-Commerce

Like all bubbles, the "dot-com" bubble burst in March 2001. A large number of e-commerce companies failed during this process. Yet for many others, such as Amazon, eBay, Expedia, and Google, the results have been more positive. By 2006, e-commerce revenues returned to solid growth, and have continued to be the fastest growing form of retail trade in the United States, Europe and Asia.

Difference in E-Commerce

Ubiquity
E-commerce is ubiquitous, meaning that is it available just about everywhere, at all times. The result is called a marketspace - a marketplace extended beyond traditional boundaries and removed from a temporal and geographic location.

Global Reach
E-commerce technology permits commercial transactions to cross cultural and national boundaries far more convenient and cost effectively than is true in traditional commerce. As a result, the potential market size for e-commerce merchants is roughly equal to the size of the world's online population.

Universal Standards
One strikingly unusual feature of e-commerce technologies is that the technical standards of the Internet and, therefore, the technical standards for conducting e-commerce are universal standards. The universal technical standards of the Internets must pay simply to bring their goods to market. At the same time, for consumers, universal standards reduce search costs - the effort to find suitable products.

Richness
Information richness refers to the complexity and content of a message. Traditional markets, national sales forces, and small retail stores have great richness: They are able to provide personal, face-to-face service using aural and visual cues when making a sale.

Interactivity
Unlike any of the commercial technologies of the twentieth century, with the possible exception of the telephone, e-commerce technologies are interactive, meaning they allow for two-way communication between merchant and consumer.

Information Density
The internet and the Web vastly increase information density - the total amount and quality of information available to all market participants, consumers and merchants alike. E-commerce technologies reduce information collection, storage, processing, and communication costs while greatly increasing the currency, accuracy, and timeliness of information. Price transparency refers to the ease with which consumers can find out the variety of prices in a market; cost transparency refers to the ability of consumers to discover the actual costs merchants pay for products. Price discrimination is selling the same goods, or nearly the same goods, to different targeted groups at different prices. 

Fig. Price Discrimination

Personalization/Customization
The technology also permits customization - changing the delivered product or service based on a user's preferences or prior behavior. The result is a result of personalization and customization unthinkable with traditional commerce technologies.

Social Technology: User Content Generation and Social Networking
In contrast to previous technologies, the Internet and e-commerce technologies have evolved to be much more social by allowing users to create and share with their personal friends (and a larger worldwide community) content in the form of text, videos, music, or photos. Using these forms of communication, users are able to create new social networks and strengthen existing ones.

Key Concepts in E-Commerce: Digital Markets and Digital Goods in a Global Marketplace
The Internet reduces information asymmetry. An information asymmetry exists when one party in a transaction has more information that is important for the transaction than the other party. Digital markets are very flexible and efficient because they operate with reduced search and transaction costs, lower menu costs (merchants' cost of changing prices), greater price discrimination, and the ability to change prices dynamically based on market conditions. In dynamic pricing, the price of a product varies depending on the demand characteristics of the customer or the supply situation of the seller. The removal of organizations or business process layers responsible for intermediary steps in a value chain is called disintermediation.
Fig. The Benefits of Disintermediation To The Consumer

Digital goods
The Internet digital marketplace has greatly expanded sales of digital goods. Digital goods are goods that can be delivered over a digital network.

E-Commerce: Business And Technology
Types of E-Commerce


There are many ways to classify electronic commerce transactions. The three major electronic commerce categories are:
  • Business-to-consumer (B2C) electronic commerce involves retailing products and services to individual shoppers.
  • Business-to-business (B2B) electronic commerce involves sales of goods and services among businesses.
  • Consumer-to-consumer (C2C) electronic commerce involves consumers selling directly to consumers.

The use of handheld wireless devices for purchasing  goods and services from any location is termed mobile commerce or m-commerce.

E-Commerce Business Models
All, in one way or another, use the Internet to add extra value to existing products and services or to provide the foundation for new products and services.

Portal
Portals such as Google, Bing, Yahoo, MSN, and AOL offer powerful Web search tools as well as integrated package of content and services such as news, e-mail, instant messaging, maps, calendars, shopping, music downloads, video streaming, and more, all in one place.

E-tailer
Online retail stores, often called e-tailers, comes in all sizes, from giant Amazon with 2010 revenues of more than 24 billion, to tiny local stores that have Web sites.

Content Provider
While e-commerce began as a retail product channel, it has increasingly turned into a global content channel. "Content" is defined broadly to include all forms of intellectual property. Intellectual property refers to all forms of human expression that can be put into a tangible medium such as text, CDs, DVDs, or stored on any digital (or other) media, including the Web. Podcasting is a method of publishing audio or video broadcasts via the Internet, allowing subscribing users to download audio or video files onto their personal computers or portable music players. Streaming is a publishing method for music and video files that flows a continuous stream of content to a user's device without being stored locally on the device.

Transaction Broker
Sites that process transactions for consumers normally handled in person, by phone, or by mail are transaction brokers. The largest industries using this model are financial services and travel services.

Market Creator
Market creators build a digital environment in which buyers and sellers can meet, display products, search for products, and establish prices.

Service Provider
While e-tailers sell products online, service providers offer services online.

Community Provider
Community providers are sites that create a digital online environment where people with similar interests can transact (buy and sell goods); share interests, photos, videos; communicate with like-minded people, receive interest-related information; and even play out fantasies by adopting online personalities called avatars.

WEB 2.0: Social Networking and The Wisdom of Crowds
At social shopping sites like Kaboodle, ThisNext, and Stylehive you can swap shopping ideas with friends. Facebook offers this smae service on a voluntary basis.

The Wisdom of Crowds
In a phenomenon called "the wisdom of crowds," some argue that large numbers of people can make better decisions about a wide range of topics or products than a single person or even a small committee of experts. Beyond merely sloliciting advice, firms can be actively helped in solving some business problems using what is called crowdsourcing. Firms can also use the wisdom of crowds in the form of prediction markets. Prediction markets are established as peer-to-peer betting markets where participants make bets on specific outcomes of, say, quarterly sales of a new product, designs for new products, or political elections.


E-Commerce Marketing
The Internet provides marketers with new ways of identifying and communicating with millions of potential customers at costs far lower than traditional media, including search engine marketing, data mining, recommended systems, and targeted e-mail. The Internet enableslong tail marketingBehavioral targeting refers to tracking the click-streams (history of clicking behavior) of individuals on thousands of Web sites for the purpose of understanding their interests and intentions, and exposing them to advertisements that are uniquely suited to their behavior.

B2B E-Commerce: New Efficiencies and Relationships
The trade between business firms (business-to-business commerce or B2B) represents a huge marketplace. The process of conducting trade among business firms is complex and requires significant human intervention, and therefore, it consumes significant resources. About 80 percent of online B2B e-commerce is still based on proprietary systems for electronic data interchange (EDI).  Private industrial networks typically consist of a large firm using an extranet to link to its suppliers and other key business partners. Another term for private industrial network is private exchangeNet marketplaces, which are sometimes called e-hubs, provide a single, digital marketplace based on Internet technology for many different buyers and sellers. Exchanges are independently owned third-party Net marketplaces that connect thousands of suppliers and buyers for spot purchasing.
Fig. A Private Industrial Network

The Mobile Digital Platform And Mobile E-Commerce
In 2010, m-commerce represented less than 10 percent of all e-commerce, with about $5 billion in annual revenues generated by selling music, videos, ring tones, applications, movies, television and location-based services like local restaurant locators and traffic updates.

M-Commerce Services And Applications

Location-Based Services
Wikitude.me provides a special kind of browser for smart phones equipped with a built-in global positioning system (GPS) and compass that can identify your precise location and where the phone is pointed.

Banking and Financial Services
Banks and credit card companies are rolling out services that let customers manage their account from their mobile devices. JPMorgan Chase and Bank of America customers can use their cell phones to check account balances, transfer funds, and pay bills.

Wireless Advertising and Retailing
Although the mobile advertising market is currently small ($784 million), it is rapidly growing (up 17 percent from last year and expected to grow to over $6.2 billion by 2014), as more and more companies seek ways to exploit new databases of location-specific information.

Games and Entertainment
Cell phones have developed into portable entertainment platforms. Smartphones like the iPhone and Droid offer downloadable and streaming digital games, movies, TV shows, music, and ringtones.

Building An E-Commerce Web Site
The two most important management challenges in building a successful e-commerce site are (1) developing a clear understanding of your business objectives and (2) knowing how to choose the right technology to achieve those objectives.

Pieces of The Site-Building Puzzle
You have to identify the key decision areas within your budget and time frame. Once you make decision, you will need to think about a plan for the project and carefully consider your site's design.

Business Objectives, System functionality, and Information Requirements
There are many choices for building and maintaining Web sites. Choices range from outsourcing the entire Web site development to an external vendor to building everything yourself (in-house).

The Building Decision
In the past, bricks-and-mortar retailers typically designed their e-commerce sites themselves (because they already had the skilled staff and IT infrastructure in place to do this). Today, however, larger retailers rely heavily on external vendors to provide sophisticated Web site capabilities, while also maintaining substantial internal staff. Medium-size start-ups will often purchase a sophisticated package and then modify it to suit their needs. Very small mom-and-pop firms seeking simple storefronts will use templates.

The Hosting Decision
With a co-location agreement, your firm purchases or leases a Web server (and has total control over its operation) but locates the server in a vendor's physical facility.

Web Site Budgets
Simple Web sites can be built and hosted with a first-year cost of $5,000 or less. The Web sites of large firms with high levels of interactivity and linkage to corporate systems cost several million dollars a year to create and operate.
