7 Mar

Business perspective on information systems:

• Information system is an instrument for creating value
• Investments in information technology will result in superior returns such as the following;
• Productivity increases
• Revenue increases
• Superior long-term strategic positioning

Information systems perspective on transforming business

• Increase in wireless technology use eg. Web sites
• Shifts in media and advertising
• New challenges in security and accounting laws
• Globalization opportunities
• Internet has drastically reduced costs of operating on global scale
• Presents both challenges and opportunities
• Businesses can operate 24/7, more convenient for consumers

Firms are increasingly becoming digital … and this digitalization seems to be powered by information systems

In the emerging, fully digital firm …..

• Significant business relationships are digitally enabled and mediated
• Core business processes are accomplished through digital networks
• Key corporate assets are managed digitally
• Digital firms offer greater flexibility in organization and management
• Time shifting, space shifting

So what is the DIGITAL FIRM?
A firm which uses information systems to become networked and decentralized and to digitalize their business processes and foster innovation and creativity.

Simply IS

4 Mar

Information systems and information technology are part of a broader computer science. IS focuses on making the best use of IT.
Not many people know or even realise that they use information systems in their everyday lives and the benefits they gain from it.
Feedback is an important element in the information system process. It is output returned to the appropriate member of the organisations to aid them in evaluation or correction.
Organisations use it to, increase productivity, deliver products and services, and to make decisions.
Research in Information Systems is apeer-reviewedacademic journal that covers research in the areas ofinformation systems andinformation technology
Major roles of an information system have three levels; strategic, tactical and operational.
An Information systems also can be defined as a collection of hardware, software, data, people and procedures that work together to produce quality information.
Tasks are completed easily that the human brain is not well suited to such as handling large amounts of information, performing complex calculations and controlling complex processes.
Information has become an important commodity such as land, labour and capital resources. It is essentially data that has been processed and that I now useful for human beings. What your reading now can be called information.
Outsourcing can be greatly aided by an efficient information system. General Motors is one company that outsourced many of its information technology operations in 2003. Doing so required co-ordinating operations and information systems among GM’s internal IT operations and numerous other companies. One major task in this process has been standardizing information technology and other software processes
Networks, people, hardware, software and data are the five main resources that make up an information systems and that are designed to generate information that supports the day-to-day, short-range, and long-range activities of users in an organization

Scientific field of study that addresses the range of strategic, managerial, and operational activities involved in the gathering, processing, storing, distributing, and use of information and its associated technologies in society and organizations
You can go into many career areas belonging to IS including information system development, management, strategy and strategy.
Sad or system analysis and design is a method used by companies to create and maintain systems that perform business functions.
Thirty percent of IS projects fail before completion  mostly because system analysts try to build wonderful systems without fully understanding the organisation first.
Examples of information systems include transaction processing systems, office systems, decision support systems, knowledge management systems, database management systems, and office information systems
Management information systems or MIS), is an information system that generates accurate, timely and organized information so managers and other users can make decisions, solve problems, supervise activities, and track progress. Because it generates reports on a regular basis, a management information system sometimes is called a management reporting system.

Information Systems as a main course!!

28 Feb

Information systems the main course to any five star meal !

Information systems are concerned with data capture, storage, analysis and retrieval. In the context the food sector and food safety management they are vital to assist decision making in a short time frame, potentially allowing decisions to be made and practices to be implemented in real time. Databases hold information on numerous items of various descriptions such as identification of pathogens, characteristics of foods and processes, supply chains etc. and these are all managed my an information system. Computer software packages a key component of any information system aid the practical application of HACCP and risk assessment to bring logical sequences to establishing and modifying food safety management practices. This particularly key in a sector such as this, a mishap or misjudgement could have harsh side effects. In addition there are many other uses of information systems that benefit food safety more globally, including: rapid communication of information on foodborne disease outbreaks through websites of many sources, including the press and interest groups, on the reasons for and consequences of foodborne disease incidents. Food supply chain management also makes use of information systems to organise and take full efficient advantage of the resources in order to get their products where they want, when they want and by the correct personnel.
National Health Programs recognize that a safe and nutritious food supply is a major contributory factor to the health of a country’s citizens and that there is a need to maintain a reputation nationally and internationally as a supplier of safe food products. Programs that ensure safe and nutritious food are receiving renewed attention in many countries and major food safety initiatives are being launched on an international scale thanks to information systems.
Food Import Management System (FIMIS) is a type of information system used by many Governments to develop things like importation policies and to guide the integration of their controls and enforcement actions. FIMIS is an authentic and reliable tool for documenting, processing and managing information related to food products. This system has optimized the prevention of consumer risk and has successfully improved the overall quality of imported foods. Furthermore, FIMIS has a built-in Online Analytical Reports (OLAP) component, which enhances decision-making processes in the food control division.

Information systems…a key part in the food sector especially when it comes to its safety. There’s just some work that should be left to a computer to manage and when dealing with the vast amount of information in this sector this is one of those times. Time is a key resource in business and is scarce at the best of times but thanks to efficient IT systems managers and key personnel have a lot more time to research, develop and implement new improvements with all this structured information at there finger tips.

A different look at information systems that I hope you enjoyed!

What makes up an Information System ?

20 Feb

The 5 main components that must come together in order to produce an Information System are;

The information system model highlights the relationships among the components and activities of information systems.

1. Hardware: The term hardware refers to machinery. This category includes the computer itself (CPU) and all of its support equipments. Among the support equipments are input and output devices, storage devices and communications devices. Computer peripherals also include the other parts such as keyboard, mouse, screen, printer for output of information and optical discs for storage of data resources.

2. Software: The concept of Software Resources includes all sets of information processing instructions. This generic concept of software includes not only the sets of operating instructions called programs, which direct and control computer hardware, but also the sets of information processing instructions needed by people, called procedures.

It is important to understand that even information systems that don’t use computers have a software resource component. This is true even for the information systems of ancient times, or the manual and machine-supported information systems still used in the world today. They all require software resources in the form of information processing instructions and procedures in order to properly capture, process, and disseminate information to their users.

The following are the examples of software resources:

  • System Software, such as an operating system program, which con controls and supports the operations of a computer system.
  • Application Software, which are programs that direct processing for a particular use of computers by end users. Examples are a sales analysis program, a payroll program, and a word processing program.

3 .Data: Data are facts that are used by programs to produce useful information. Like programs, data are generally stored in machine-readable form on disk or tape until the computer needs them. It must be managed effectively to benefit all end users in an organization. It can take many forms from letters and numbers, sentences and paragraphs, images and audio sounds. . Data are raw facts or observations, typically about physical phenomena or business transactions. For example, a spacecraft launch or the sale of an automobile would generate a lot of data describing those events.

            V’s             

Information is data that have been converted into a meaningful and useful context for specific end users.. So you should view information as processed data placed in a context that gives it value for specific end users.

Example: Names, quantities, and money, amounts recorded on sales forms represent data about sales transactions. However, a sales manager may not regard these as information. Only after such facts are properly organized and manipulated can meaningful sales information be furnished, specifying, for example, the amount of sales by product type, sales territory, or sales persons.

4. Networks:  A computer network is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network.

Telecommunications networks like the Internet, intranets, and extranets have become essential to the successful operations of all types of organizations and their computer-based information systems. Telecommunications networks consist of computers, communications processors, and other devices interconnected by communications media and controlled by communications software. The concept of Network resources emphasizes that communications networks are a fundamental resource component of all information systems. Network resources include:

5. People: Every Information System needs people if it is to be useful. Often the most over-looked element of an information system is the people, probably the component that most influence the success or failure of information systems. People are required for the operation of all information systems and these people resources include end users and IS specialists.

  • End users (also called users or clients) are people who use an information system or the information it produces. They can be accountants, salespersons, engineers, clerks, customers, or managers. Most of us are information system end users.
  • IS Specialists are people who develop and operate information systems. They include systems analysts, programmers, computer operators, and other managerial technical, and clerical IS personnel. Briefly, systems analysts design information systems based on the information requirements of end uses, programmers prepare computer programs based on the specifications of systems analysts, and computer operators operate large computer systems.

 These components combine to make an efficient Information System if issing any of these elements it just would simply not work. Further post will include more examples of organisations and a more practical outlook on Information Systems.

Information Systems In Organisations

4 Feb

All organisations share one common asset, regardless of the type of business. It doesn’t matter if they manufacture goods or provide services. It is a vital part of any business entity, whether a sole proprietor or a multinational corporation. That common asset is information.

Information is power and the more of it held the more powerful an organisation can become but information has a far lesser impact when presented as raw data. In order to maximise its value and a firms resources it must be collected, retrieved, processed, stored and distributed. In order to accomplish this an Information System must be designed, developed, administered and maintained. This is a computer system that provides management and other personnel within an organisation with up-to-date information regarding the organizations performance; for instance current sales and stock. These systems output information in a form that is useable at all levels of the organization: strategic, tactical, and operational. It combines business with computer science as the two harmonise to in order to complete the three major roles of an information system: Support business processes and operations; support business decision making; and support competitive advantage and decision making. (as shown in the diagram below)

An information system is a key part to any successful organisation. It needs to be communicated correctly to the analyst who designs it in order to be tailored to the end users needs. Unfortunately this in the past has been found difficult with over 50% of IS projects failing. This can be sometimes because the analysts try to create very elaborate systems that impress without fully understanding the organisation itself. Design is a very crucial phase in the development of a system and needs to be precise yet happen in a reasonable period of time. It can mean the difference between success and failure.

I will later discuss more about the components of an information system and have a more in depth look into its roles.
