            --The product can be physical or digital.
            --The process can be physical or digital.
            --The delivery agent can be physical or digital.
        Brick-and-mortar organizations are purely physical organizations.
        Virtual organizations are companies that are engaged only in EC. (Also called pure play)
        Click-and-mortar organizations are those that conduct some e-commerce activities, yet their business is primarily done in the physical world. i.e. partial EC.

5.  List and describe the various eBusiness models
E-business models are an approach to conducting electronic business on the Internet. These transactions take place between two main entities- businesses and consumers. The e-business models are stated below:
  • Business-to-business (B2B) Applies to businesses buying from and selling to each other over the internet.
  • Business-to-consumer (B2C) Applies to any business that sells its products or services to consumers over the internet
  • Consumer-to-business (C2B) Applies to any consumer that sells a product or service to a business over the internet
  • Consumer-to-Consumer (C2C) Applies to sites primarily offering goods and services to assist consumers interacting with each other over the internet.

6.  List and describe the major B2B marketplace models? 
Business-to-business (B2B) applies to businesses buying from and selling to each other over the internet. Electronic marketplaces, or e-marketplaces, are interactive business communities providing a central market where multiple buyers and sellers can engage in e-business activities. Each presents structures for conducting commercial exchange, consolidating supply chains, and creating new sales channels. Their primary goal is to increase market efficiency by tightening and automating the relationship between buyers and sellers. Those existing e-marketplaces allow access to various mechanisms in which to buy and sell a range of things, from services to direct materials. These transactions are generally conducted via extranet – (individual companies’ intranets connected together using high levels of network security (often using a virtual private network, or VPN).

Business Information Technology - Week Three Questions

(TPS) Transaction processing systems and (DSS) decision support systems are two of three common types of decision making information systems used in organisations today. Both systems use different models to assist in decision making, problem solving and opportunity capturing. An example of these systems in business is as follows. TPS – Analysts and DSS- Managers.
2)      Describe three quantitative models typically used by decision support systems
A decision support system (DSS) models information to support managers and business professionals during the decision making process. The three quantitative models used by DSS include:
-          Sensitivity analysis: The study of the impact that changes in one (or more) parts of the model. Users change the value of one variable repeatedly and observe the resulting changes in other variables.
-          What if analysis: Checks the impact of a change in an assumption on the proposed solution. Users repeat this analysis until they understand the effects of various situations.
-          Goal-Seeking analysis: Finds the inputs necessary to achieve a goal. Instead of observing how changes in a variable affect other variables as in what-if analysis, goal-seeking analysis sets a target value or a goal for a variable and then repeatedly changes other variables until the target value is achieved.

3)      Describe a business processes and their importance to an organisation, outline and examine how they are used
A business process is a standardised set of activities that accomplish a specific task such as processing a customer’s order. The importance of a business process is significantly relevant to how the business runs and its outcome of success. Business processes transform a set of inputs into a set of outputs; otherwise known as goods and services for another person or process by using people and tools. Organisations are only as effective as their business process and by developing this it can logically help an organisation achieve its goals.

4)      Compare business process improvement and business process re-engineering
Business Process Improvement attempts to understand and measure the current process and make performance improvements accordingly. Whereas Business Process re-engineering is the analysis and redesign of works from within and between enterprises. Unlike process Improvement, this relies on a different school of thought.


5)      Describe the importance of business process modelling(or mapping) and business process models
Business Process Modelling (or mapping) is the activity of creating a detailed flowchart or process map of a work process, showing its inputs, tasks and activities in a structured sequence. Business process models are a graphic description of a process, showing the sequence of process tasks, which is developed for a specific purpose and from a selected viewpoint. Each process exposes process detail gradually and in a controlled manner and provides a powerful analysis and consistent design vocabulary.

Business Information Technology - Week Two Questions

Explain the role of information technology’s role in business
Information technology is everywhere and it enables some businesses to differentiate themselves from competitors to gain competitive advantage. It works to maximise the efficiency of IT operations so that the business can focus on their resources on providing value for the business. Further more, it allocates the business with information and communication thus creating positive effectiveness.


What are efficiency and effectiveness metrics? (Provide examples)
-          Efficiency IT metrics measures the performance of the IT system itself including throughput, speed, and availability. Getting the most from each source. Some include: Throughput, transaction speed, system availability, web traffic, response time, and information accuracy. The main focus of efficiency is based of technology and how it operates. Examples of Efficiency IT metrics are as follows: 40% of equipment (on average) is in Development/Test, vs. Production
-          Data Centre greenhouse emissions will surpass that or airlines by 2020
-          Server utilization is still low; up to 30% of servers are "dead"; average cooling utilization is only 50%
-          Effectiveness IT metrics measures the impact IT has on business processes and activities including customer satisfaction, conversion rates, and sell through increases. Setting the right goals and seeing they are accomplished. The main focus of efficiency is based around an organisations goals, strategies and objectives. Some include: Usability, customer satisfaction, conversion rates and financial. Examples of effectiveness IT metrics are as follows:
-          Mean Time to Repair: How long it takes to resolve an outage.
-          Server to System Administration Ratio: Number of servers that can be handled by an administrator (high performers can handle about 125 servers.. while medium and low performers can handle about 25)
-          First Fix Rate: The percentage of incidents that are correctly repaired the first time.
-          Change Success Rate: Percent of changes that are successfully deployed without creating an incident.


What does Porters give forces Model attempt to explain? How does the internet affect the model?

1) Buyer Power
2) Supplier Power
3) Threat of substitute products or services
4) Threat of new entrants
5) Rivalry among existing competitors

These forces attempt to help companies identify potential opportunities while deterring potential rivals. It helps to determine the relative attractiveness of an industry. Information technology increases competition as availability of information increases, thus the more the internet displays information technology, the more competitive the market will become for the business.

Describe the relationship between processes and value chains

-  The Value chain enables a firm to evaluate activities that add value to a firm’s products and services used within the organisation. It views an organisation as a series of processes, each of which adds value to the product or service.  In comparison to Business Processes which is a standardised set of activities that accomplish a specific task. The relationship between the two are branched down and connected from the value creation which is the result of effective business processes and efficient value chains. Both enable support activities and can decrease the threat of new entrants; moreover improving primary activities can decrease the threat of substitutes.
