Improved Decision-Making:
Many managers who operation in an information bank may never have the right information at the right time to make an informed decision. This can raise costs and lose customers. However, information systems allow the managers to use real-time data from the marketplace when making decision.

Competitive Advantage:
When a firm achieved one or more of these business objectives (operational excellence, new products, services and business models, customer/supplier intimacy and improved decision-making), they may have a competitive advantage. By performing better than competitors, charging less for superior goods and responding to customers and suppliers, higher sales and profits can be made.

Day To Day Survival:
Businesses must invest in information systems and technology as they are essential to doing business. This necessity is caused by the industry level changes and firms need to use information systems and technology in order to provide the capability to respond to these.

They provide new markets, new businesses and affect other competitors.

Many organizations that have done substantial amount of work with computers since that 1950’s have long used the term “strategic planning”. This term is used for any computer development that directly affects the conduct of the business. If a manager is interested in the outcome of a systems development because they feel it would affect their profitability, then the system is strategic.

A strategic system matches the information services resources to the business strategic opportunities where the computer systems will have an effect on the products the business produces or the operation of the business. Planning for strategic systems is not marked on calendar cycles or routine planning, rather it is the effort that is required to have an impact on the competitive environment and the firms strategy at that time that the management wants to implement on the idea.

How to maintain Information Systems

2 Mar

Organisations need to establish filing systems to accommodate the different types of records they need to keep. These files must be updated regularly and accurate to maintain the integrity of the files. A business might establish a centralised filing system where all there records are kept it one area or a non-centralised systems which are seen in departments within organisations who have control of their own records. These files can be paper-based (stored in cabinets), electronic (computer systems), stored in fixed filing areas (filing cabinets or compactus units) or in a portable filing system (can be easily moved from one area to another).

It is essential that computer operators and staff understand how to manage electronic files within the organisation, such as how files are named and how folders are used. How to organisation’s information is stored depends on the following:

The amount of information to be stored: Large amounts of information are easier to store in a computer database rather than a paper-based storage system. This allows many people to access the information easily, especially if the organisation is spread throughout various locations.

The size of the workplace/organisation: This refers to the size of the organisation and also the number of employees. A large workplace area has the ability to store paper-based information in filing cabinets or compactus units, whereas a small workplace area could store more information electronically or digitally. If an organisation has a large number of employees, the method of storing information depends on how many people need the information and where these people are located within the organisation.

How work is conducted: Some organisations are more electronically up-to-date than others and they tend to store information electronically rather than paper-based. If there are a large number of employees who operate outside the organisation, electronic information are digital communication are more suitable.

The amount of storage space available: If there is limited storage space, less paper files can be stored. Inactive or dead files would need to be identified and disposed of so as the storage space can be used most effectively.

How often records need to be accessed: Records that are used most often would need to be accessed easily. Paper-based files would be stored centrally if the workplace area is relatively small or stored non-centrally to give access to the relevant department. Information can also be stored electronically so as it could be accessed by all employees.

Security required:Paper-based information can be stored in a locked filing cabinet in a secure area or a locked room. Keys can be given to employees who have the authority to access these information. For electronic information, passwords would be required to restrict access and regular backing-up information would be needed in case of a power failure or a computer virus.

Cost of storage equipment: Computers and other electronic equipment are expensive and must be updated and maintain regularly whereas filing cabinets last for a long period of time and are one-off expenses.

Protection for environmental effects: All files must be protected at all times from fire, flood, theft, etc.

Stages in implementing an information system

20 Feb

The main goal within an organization when implementing an information system is to increase efficiency in organization activity by means of IT.
For example: automatic information processing, adequate information and document management.

The implementation stages of an information system includes:

Problem analysis and specification design: The IT team analyses and defines the problem accurately. However, the users have to describe their complete requirements or specifications. Therefore, the involvement of the organization in providing complete and precise specifications for its needs are essential. Incomplete requirements will lead to inadequate systems and disadvantages in resource allocation for both the IT team and organization.

Design and implementation of the application: This stage is performed by the IT teams based on the specifications required. This stages examines the “how to do” and “do it” by the IT team. This involves the architecture design, choosing programming languages and environments, application implementation and application testing.

System installation: This is performed within the organization as it takes into account the user feedback and, if necessary, make adjustments where it is required.

Maintenance: This stage comes after the system installation. It involves all the necessary operations in order to ensure that there is an efficient exploitation of the system within the organization and performs adjustments where it is required as well as developing the organization’s activity.

Advantages and disadvantages of information systems for businesses

16 Feb

Maintaining the latest information system involves five elements.
– Hardware
– Software
– Data
– People
– Process

The hardware must be reliable and maintain the ability to handles various workloads. Software must be designed carefully and evaluated in such a way as to maximise its effectiveness. All the data entered into the computer must be accurate. The people who maintain these systems must be highly skilled and knowledgeable enough to be able to handle the latest information systems, and the users must be taught how to operate the system.

There are many advantages of implementing information systems for businesses. It allows the user to access and to understand the information therefore allowing them to respond to information quickly and effectively. The user can get the most accurate and up-to-date information quickly which is very important for businesses as these decisions affect the business. In addition to this, information systems also allows users to alternate and present information, as well as perform different tasks.

However, there are some disadvantages of using information systems in businesses. One main problem is that information systems may not function properly which affects the running of the business. This can result in system break down, interrupting smooth operations and consumer dissatisfaction. Defective information systems can deliver wrong information to other systems which could create problems for the business and its customers. Information systems are also vulnerable to hackers and frauds.
