Question

Compose an essay to address the elements listed below.

Identify the components of an information system (IS) using the five-component framework, and provide a brief summary of each.

Explain Porter’s five forces model.

Management IS (MIS) incorporate software and hardware technologies to provide useful information for decision-making.

Explain each of the following IS, and use at least one example in each to support your discussion: a collaboration information system, a database management system, a content management system, a knowledge management/expert system, a customer relationship management system, an enterprise resource planning system, a social media IS, a business intelligence/decision support system, and an enterprise IS.

Identify and discuss one technical and one human safeguard to protect against IS security threats. There are several processes that can be used to develop IS and applications such as systems development life cycle (SDLC) and scrum (agile development). Provide a brief description of SDLC and scrum, and then discuss at least one similarity and one difference between SDLC and scrum Sum up your paper by discussing the importance of MIS.

Explanation / Answer

The five essential components of IS are hardware, software, data, procedures/ network and peope.

Hardware refers to input output devices basically the machinery, processor, operating system and media devices.

Software refers to various programmes and the procedures/ manuals that supports hardware. Programes are generally stored in some input/ output medium, often a disk/ tape.

Data are facts that are used by programs to produce useful information, rather database as we can say consists of various programs and procedures.

Network/ Procedures are to people what software is to hardware - basically is consists of communication media, hubs and network devices

People consists of device operators, network administrators and system specialists.

PORTERS FIVE FORCES MODEL

The Porters Five forces model, helps to explain why different industries are able to susbstain different levels of profitability. The forces are frequently used to measure competition intensity, attractiveness and profitability of an industry or market. These forces are

Threat of new entrants - Profitable industries attract new entrants which eventually will decrease profitability of other firms in industry. The following factors can have effect on how much a threat new entrants may pose 1. Capital requirements 2. Absolute cost 3. Network effect 4. Access to distribution channels atc

Bargaining power of consumers - This refers to the ability customers have to drive the prices down. Bargaining power can also be described as market outputs, and firms can reduce buyers power. It is high when buyers have many alternatives and buyers power is low if they have few choices. Factors .1 Buyers information availability, 2. buyers price sensitivity, 3. differential advantage of industry products

Bargaining power of suppliers - This force addresses how easily suppliers can drive up price of goods and services. The key suppliers to the firm such as labour, raw material, and services to the firm can be a source of power over the firm when there are few substitues. Potential factors are 1. Presence of substitue inputs 2. Strength of distribution channels 3. impact of inputs on cost and differentiation

Threath of substitutes - Products from competitiors that can be used as sustitues in place of company's products pose a threath, example of substitues are coke and pepsi, landline and cellular telephones etc. Potential factors : 1. Buyers switching cost, 2. Ease of substitution, 3. Availability of close substitutes

Industry rivarly refers to the number of compititors and their ability to threathen the company, a business must be aware of its compitiors policies and also be reactive to the changes in industry . Potential factors are 1. Level of advertising expense 2. Firm concentration ratio 3. power of competative strategy

Understanding Porter's five forces enables a company to optimise its resources and gives better returns to its investors

hardware and software - can be protected by firewalls, application designs and encryption

procedures and people that is human safeguard can be obtained by hireing, training, education , compliance assessment

SDLC is a term used i system enginerring and and software enginerring to describe process fro planning creating testing and deploying information system
