<\/i>a. Open-source software is software that makes the source code available for anyone to copy and use. It is free to download, copy, and distribute. Closed-source software does not make the source code available and generally is not free to download, copy, and distribute. There are <\/i>many<\/i> examples <\/i>of<\/i> both, such as: Firefox (open source), Linux (open source), iTunes (closed source), Microsoft Office (closed source). <\/i><\/p>\n

9. What does a software license grant?<\/p>\n

<\/i>a. Software licenses are not all the same, but generally the<\/i>y<\/i> grant the user <\/i>the right<\/i> to use the software on a limited basis. The terms of the license dictate <\/i>users\u2019<\/i> rights <\/i>in detail<\/i>. <\/i><\/p>\n

10. How did the Y2K (year 2000) problem affect the sales of ERP systems?<\/p>\n

 <\/p>\n

Chapter 4<\/p>\n

 <\/p>\n

1. What is the difference between data, information, and knowledge?<\/p>\n

<\/i>a. Data are the raw bits and pieces of facts and statistics with no context. Data can be quantitative or qualitative. Information is data that has been given context. Knowledge is information that has been aggregated and analyzed and can be used for making decisions. <\/i><\/p>\n

2. Explain in your own words how the data component relates to the hardware and software components of information systems.<\/p>\n

<\/i>a. There are <\/i>numerous<\/i> answers to this question, <\/i>but all should be <\/i>variations on<\/i> the following<\/i>: Data is processed by the hardware via software. A database is software that runs on the hardware. Hardware stores the data, software processes the data.<\/i><\/p>\n

3. What is the difference between quantitative data and qualitative data? In what situations could the number 42 be considered qualitative data?<\/p>\n

<\/i>a. Quantitative data is numeric, the result of a measurement, count, or some other mathematical calculation. Qualitative data is descriptive. The number 42 could be qualitative if it is a designation instead of a measurement, count, or calculation. For example: that player<\/i>\u2019<\/i>s jersey has number 42 on it. <\/i><\/p>\n

4. What are the characteristics of a relational database?<\/p>\n

<\/i>a. A relational database is one in which data is organized into one or more tables. Each table has a set of fields, which define the nature of the data stored in the table. A record is one instance of a set of fields in a table. All the tables are related by one or more fields in common.<\/i><\/p>\n

5. When would using a personal DBMS make sense?<\/p>\n

<\/i>a. When working on a smaller database for personal use, or when disconnected from the network. <\/i><\/p>\n

6. What is the difference between a spreadsheet and a database? List three differences between them.<\/p>\n

<\/i>a. A database is generally more powerful and complex than a spreadsheet, with the ability to handle multiple types of data and link them together. Some differences: A database has defined field types, a spreadsheet does not. A database uses a standardized query language (such as SQL), a spreadsheet does not. A database can hold much larger amounts of data than a spreadsheet. <\/i><\/p>\n

7. Describe what the term normalization<\/i> means.<\/p>\n

<\/i>a. To normalize a database means to design it in a way that: 1) reduces duplication of data between tables and 2) gives the table as much flexibility as possible.<\/i><\/p>\n

8. Why is it important to define the data type of a field when designing a relational database?<\/p>\n

<\/i>a. A data type tells the database what functions can be performed with the data. The second important reason to define <\/i>the <\/i>data type is so that the proper amount of storage space is allocated for <\/i>the<\/i> data. <\/i><\/p>\n

9. Name a database you interact with frequently. What would some of the field names be?<\/p>\n

<\/i>a. The student can choose any sort of system that they interact with, such as Amazon or their school<\/i>\u2019<\/i>s online systems. The fields would be the names of data being collected, such as <\/i>\u201c<\/i>first name<\/i>\u201d<\/i>, or <\/i>\u201c<\/i>address<\/i>\u201d<\/i>. <\/i><\/p>\n

10. What is metadata?<\/p>\n

<\/i>a. Metadata is data about data<\/i>.<\/i> It refers to the data used to describe other data, such as the length of a song in iTunes, which describes the music file. <\/i><\/p>\n

11. Name three advantages of using a data warehouse.<\/p>\n

<\/i>a. The text lists the following<\/i> <\/i>(<\/i>the student should pick at least three of these<\/i>)<\/i>: <\/i><\/p>\n

<\/i>i. The process of developing a data warehouse forces an organization to better understand the data that it is currently collecting and, equally important, what data is not being collected.<\/i><\/p>\n

<\/i>ii. A data warehouse provides a centralized view of all data being collected across the enterprise and provides a means <\/i>of<\/i> determining data that is inconsistent.<\/i><\/p>\n

<\/i>iii. Once all data is identified as consistent, an organization can generate one version of the truth. This is important when the company wants to report consistent statistics about itself, such as revenue or number of employees.<\/i><\/p>\n

<\/i>iv. By having a data warehouse, snapshots of data can be taken over time. This creates a historical record of data, which allows for an analysis of trends.<\/i><\/p>\n

<\/i>v. A data warehouse provides tools to combine data, which can provide new information and analysis.<\/i><\/p>\n

12. What is data mining?<\/p>\n

<\/i>a. Data mining is the process of analyzing data to find previously unknown trends, patterns, and associations in order to make decisions. <\/i><\/p>\n

9. What is the difference between an intranet and an extranet?<\/p>\n

<\/i>a. An intranet consists of t<\/i>he set of web pages and resources availab<\/i>le on a<\/i> company\u2019s internal network.<\/i> These items are not available to those outside of the company. An extranet<\/i> <\/i>is<\/i> a part of the company's network that <\/i>is<\/i> made available securely to those outside of the company. Extranets can be used to allow customers to log in and check the status of their orders, or for suppliers to check their customers' inventory levels.<\/i><\/p>\n

10. What is Metcalfe\u2019s Law?<\/p>\n

<\/i>a. Metcalfe\u2019s Law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system.<\/i><\/p>\n

 <\/p>\n

Chapter 6<\/p>\n

 <\/p>\n

1. Briefly define each of the three members of the information security triad.<\/p>\n

<\/i>a. T<\/i>he three members are as follows:<\/i><\/p>\n

<\/i>i. Confidentiality: we want to be able to restrict access to those who are allowed to see <\/i>given information.<\/i> <\/i><\/p>\n

<\/i>ii. Integrity: the assurance that the information being accessed has not been altered and tr<\/i>uly represents what is intended.<\/i> <\/i><\/p>\n

<\/i>iii. Availability: information can be accessed and modified by anyone authorized to do so in an appropriate timeframe.<\/i><\/p>\n

2. What does the term authentication<\/i> mean?<\/p>\n

<\/i>a. The process of ensuring that a person is <\/i>who<\/i> <\/i>he or she<\/i> claim<\/i>s<\/i> to be. <\/i><\/p>\n

3. What is multi-factor authentication?<\/p>\n

<\/i>a. The use of more than one method of authentication. The methods are: something you know, something you have, and something you are. <\/i><\/p>\n

4. What is role-based access control?<\/p>\n

<\/i>a. With role-based <\/i>access control (RBAC), instead of giving specific users access rights to an information resource, users are assigned to roles and then those roles are assigned the access. <\/i><\/p>\n

5. What is the purpose of encryption?<\/p>\n

<\/i>a. To keep <\/i>transmitted <\/i>data secret so that only those with the proper key can read it. <\/i><\/p>\n

6. What are two good examples of a complex password?<\/p>\n

<\/i>a. There are many examples of this. Students need to provide examples of passwords that are a minimum of eight characters, <\/i>with<\/i> at least one upper-case letter, one special character, and one number. <\/i><\/p>\n

7. What is pretexting?<\/p>\n

<\/i>a. Pretexting occurs when an attacker calls a helpdesk or security administrator <\/i>and pretends<\/i> to be a particular <\/i>authorized user<\/i> having trouble logging in<\/i>. <\/i>Then, by providing some personal information about <\/i>the authorized user<\/i>, <\/i>the attacker<\/i> convince<\/i>s<\/i> the <\/i>security <\/i>person to reset the password and <\/i>tell him what it is<\/i>.<\/i><\/p>\n

8. What are the components of a good backup plan?<\/p>\n

<\/i>a. Knowing what needs to be backed up, regular backups of all data<\/i>, offsite storage of all backed-<\/i>up data, and a test of the restoration process. <\/i><\/p>\n

9. What is a firewall?<\/p>\n

<\/i>a. A firewall can be either a hardware firewall or a software firewall. A hardware firewall is a device that is connected to the network and filters the packets based on a set of rules. A software firewall runs on the operating system and intercepts packets as they arrive to a computer.<\/i><\/p>\n

10. What does the term physical security<\/i> mean?<\/p>\n

<\/i>a. Physical security is the protection of the actual hardware and networking components that store and transmit information resources.<\/i><\/p>\n

Chapter 7<\/p>\n

 <\/p>\n

1. What is the productivity paradox?<\/p>\n

<\/i>a. The productivity paradox is <\/i>based on <\/i>Erik <\/i>Brynjolfsson\u2019s<\/i> <\/i>finding<\/i>, based on research he conducted in the early 1990s, <\/i>that the addition of information technology to business<\/i> had not improved productivity at all.<\/i><\/p>\n

2. Summarize Carr\u2019s argument in \u201cDoes IT Matter.\u201d<\/p>\n

<\/i>a. Information technology is now a commodity and cannot be used to provide an organization with competitive advantage. <\/i><\/p>\n

3. How is the 2008 study by Brynjolfsson and McAfee different from previous studies? How is it the same?<\/p>\n

<\/i>a. It is different because it shows that IT can bring a competitive advantage, given the right conditions. It is the same in <\/i>the sense <\/i>that it shows that IT, by itself, does not bring competitive advantage. <\/i><\/p>\n

4. What does it mean for a business to have a competitive advantage?<\/p>\n

<\/i>a. A company is said to have a competitive advantage over its rivals when it is able to sustain profits that exceed average for the industry. <\/i><\/p>\n

5. What are the primary activities and support activities of the value chain?<\/p>\n

<\/i>a. The primary <\/i>activities<\/i> are <\/i>those<\/i> that directly impact the creation of a product or service. The support <\/i>activities<\/i> are <\/i>those<\/i> that support the primary activities. Primary: inbound logistics, operations, outbound logistics, sales\/marketing, and service. Support: firm infrastructure, human resources, technology development, <\/i>and procurement<\/i>. <\/i><\/p>\n

6. What has been the overall impact of the Internet on industry profitability? Who has been the true winner?<\/p>\n

<\/i>a. The overall impact <\/i>has been<\/i> a reduction in average industry profitability. The consumer has been the true winner. <\/i><\/p>\n

7. How does EDI work?<\/p>\n

<\/i>a. EDI is the computer-to-computer exchange of business documents in a standard electronic format between business partners.<\/i><\/p>\n

8. Give an example of a semi-structured decision and explain what inputs would be necessary to provide assistance in making the decision.<\/p>\n

<\/i>a. A semi-structured decision is one in which most of the factors needed for making the decision are known but human experience and other outside factors may still play a role. The student should provide an example of a decision that uses an information system to provide information but is not made by the system. Examples would include: budgeting decisions, diagnosing a medical condition, and investment decisions. <\/i><\/p>\n

9. What does a collaborative information system do?<\/p>\n

<\/i>a. A collaborative system is software that allows multiple users to interact on a document or topic in order to complete a task or make a decision.<\/i><\/p>\n

10. How can IT play a role in competitive advantage, according to the 2008 article by Brynjolfsson and McAfee?<\/p>\n

<\/i>a. The article suggests that <\/i>IT can influence competitive advantage when <\/i>good management develops and delivers <\/i>IT-supported <\/i>process <\/i>innovation<\/i>.<\/i><\/p>\n

 <\/p>\n

Chapter 8<\/p>\n

 <\/p>\n

1. What does the term business process<\/i> mean?<\/p>\n

<\/i>a. A process is a series of tasks that are completed in order to accomplish a goal. A business process, therefore, is a process that is focused on achieving a goal for a business. <\/i><\/p>\n

2. What are three examples of business process from a job you have had or an organization you have observed?<\/p>\n

<\/i>a. Students can answer this in almost any way. The examples should consist of more than a single step. <\/i><\/p>\n

3. What is the value in documenting a business process?<\/p>\n

<\/i>a. There are many answers to this. From the text: it allows for better control of the process<\/i>,<\/i> and <\/i>for <\/i>standardization. <\/i><\/p>\n

4. What is an ERP system? How does an ERP system enforce best practices for an organization?<\/p>\n

<\/i>a. An ERP (enterprise resource p<\/i>lanning) system is a software application with a centralized database that is implemented across the entire organization. It enforces best practices through the business processes embedded in the software. <\/i><\/p>\n

5. What is one of the criticisms of ERP systems?<\/p>\n

<\/i>a. ERP system<\/i>s<\/i> can lead to the commoditization of business processes, meaning that every company that uses an ERP <\/i>system <\/i>will perform business processes the same way. <\/i><\/p>\n

6. What is business process reengineering? How is it different from incrementally improving a process?<\/p>\n

<\/i>a. Business process r<\/i>eengineering (BPR) occurs when a business process is redesigned from the ground up. It is different from incrementally improving a process <\/i>in that<\/i> it does not simply take the existing process and modify it. <\/i><\/p>\n

7. Why did BPR get a bad name?<\/p>\n

<\/i>a. BPR became an excuse to lay<\/i> <\/i>off employees and try to complete the same amount of work using fewer employees. <\/i><\/p>\n

8. List the guidelines for redesigning a business process.<\/p>\n

<\/i>a. The guidelin<\/i>es are as follows:<\/i> <\/i><\/p>\n

<\/i>i. Organize around outcomes, not tasks. <\/i><\/p>\n

<\/i>ii. Have those who use the outcomes of the process perform the process.<\/i><\/p>\n

<\/i>iii. Subsume information-processing work into the real work that produces the information. Treat geographically dispersed resources as though they were centralized.<\/i><\/p>\n

<\/i>iv. Link parallel activities instead of integrating their results. <\/i><\/p>\n

<\/i>v. Put the decision points where the work is performed, and build controls into the process. <\/i><\/p>\n

<\/i>vi. Capture information once, at the source. <\/i><\/p>\n

9. What is business process management? What role does it play in allowing a company to differentiate itself?<\/p>\n

<\/i>a. Business process management (BPM) can be thought of as an intentional effort to plan, document, implement, and distribute an organization<\/i>\u2019<\/i>s business processes with the support of information technology. It can play a role in differentiation <\/i>through built-in reporting, and <\/i>by empowering employees, enforcing best practices, <\/i>and <\/i>enforcing consistency. <\/i><\/p>\n

10. What does ISO certification signify?<\/p>\n

<\/i>a. ISO certification shows that you know what you do, do what you say, and have documented your processes. <\/i><\/p>\n

<\/i>a. To allow for career growth for those who do not want to manage other employees but instead want to focus on technical skills. <\/i><\/p>\n

7. What are the advantages and disadvantages of centralizing the IT function?<\/p>\n

<\/i>a. There are several possible answers here. Advantages <\/i>of<\/i> centralizing include more control over the company\u2019s systems and data. Disadvantages include a more limited availability of IT resources. <\/i><\/p>\n

8. What impact has information technology had on the way companies are organized?<\/p>\n

<\/i>a. The organizational structure has been flattened, with fewer layers of management. <\/i><\/p>\n

2. How does Friedman define the three eras of globalization?<\/p>\n

<\/i>a. The three eras are as follows:<\/i> <\/i><\/p>\n

<\/i>i. \u201c<\/i>Globalization 1.0<\/i>\u201d<\/i> occurred from 1492 until about 1800. In this era, globalization was centered around countries. It was about how much horsepower, wind power, and steam power a country had and how creatively it was deployed. The world shrank from size <\/i>\u201c<\/i>large<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>medium.<\/i>\u201d<\/i><\/p>\n

<\/i>ii. \u201c<\/i>Globalization 2.0<\/i>\u201d<\/i> occurred from about 1800 until 2000, interrupted only by the two World Wars. In this era, the dynamic force driving change was <\/i>comprised of <\/i>multinational companies. The world shrank from size <\/i>\u201c<\/i>medium<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>small.<\/i>\u201d<\/i><\/p>\n

<\/i>iii. \u201c<\/i>Globalization 3.0<\/i>\u201d<\/i> is our current era, beginning in the year 2000. The convergence of the personal computer, fiber-optic Internet connections, and software has created a <\/i>\u201c<\/i>flat-world platform<\/i>\u201d<\/i> that allows small groups and even individuals to go global. The world has shrunk from size <\/i>\u201c<\/i>small<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>tiny.<\/i>\u201d<\/i><\/p>\n

Chapter 4<\/p>\n

 <\/p>\n

1. What is the difference between data, information, and knowledge?<\/p>\n

<\/i>a. Data are the raw bits and pieces of facts and statistics with no context. Data can be quantitative or qualitative. Information is data that has been given context. Knowledge is information that has been aggregated and analyzed and can be used for making decisions. <\/i><\/p>\n

2. Explain in your own words how the data component relates to the hardware and software components of information systems.<\/p>\n

<\/i>a. There are <\/i>numerous<\/i> answers to this question, <\/i>but all should be <\/i>variations on<\/i> the following<\/i>: Data is processed by the hardware via software. A database is software that runs on the hardware. Hardware stores the data, software processes the data.<\/i><\/p>\n

3. What is the difference between quantitative data and qualitative data? In what situations could the number 42 be considered qualitative data?<\/p>\n

<\/i>a. Quantitative data is numeric, the result of a measurement, count, or some other mathematical calculation. Qualitative data is descriptive. The number 42 could be qualitative if it is a designation instead of a measurement, count, or calculation. For example: that player<\/i>\u2019<\/i>s jersey has number 42 on it. <\/i><\/p>\n

4. What are the characteristics of a relational database?<\/p>\n

<\/i>a. A relational database is one in which data is organized into one or more tables. Each table has a set of fields, which define the nature of the data stored in the table. A record is one instance of a set of fields in a table. All the tables are related by one or more fields in common.<\/i><\/p>\n

5. When would using a personal DBMS make sense?<\/p>\n

<\/i>a. When working on a smaller database for personal use, or when disconnected from the network. <\/i><\/p>\n

6. What is the difference between a spreadsheet and a database? List three differences between them.<\/p>\n

<\/i>a. A database is generally more powerful and complex than a spreadsheet, with the ability to handle multiple types of data and link them together. Some differences: A database has defined field types, a spreadsheet does not. A database uses a standardized query language (such as SQL), a spreadsheet does not. A database can hold much larger amounts of data than a spreadsheet. <\/i><\/p>\n

7. Describe what the term normalization<\/i> means.<\/p>\n

<\/i>a. To normalize a database means to design it in a way that: 1) reduces duplication of data between tables and 2) gives the table as much flexibility as possible.<\/i><\/p>\n

8. Why is it important to define the data type of a field when designing a relational database?<\/p>\n

<\/i>a. A data type tells the database what functions can be performed with the data. The second important reason to define <\/i>the <\/i>data type is so that the proper amount of storage space is allocated for <\/i>the<\/i> data. <\/i><\/p>\n

9. Name a database you interact with frequently. What would some of the field names be?<\/p>\n

<\/i>a. The student can choose any sort of system that they interact with, such as Amazon or their school<\/i>\u2019<\/i>s online systems. The fields would be the names of data being collected, such as <\/i>\u201c<\/i>first name<\/i>\u201d<\/i>, or <\/i>\u201c<\/i>address<\/i>\u201d<\/i>. <\/i><\/p>\n

10. What is metadata?<\/p>\n

<\/i>a. Metadata is data about data<\/i>.<\/i> It refers to the data used to describe other data, such as the length of a song in iTunes, which describes the music file. <\/i><\/p>\n

11. Name three advantages of using a data warehouse.<\/p>\n

<\/i>a. The text lists the following<\/i> <\/i>(<\/i>the student should pick at least three of these<\/i>)<\/i>: <\/i><\/p>\n

<\/i>i. The process of developing a data warehouse forces an organization to better understand the data that it is currently collecting and, equally important, what data is not being collected.<\/i><\/p>\n

<\/i>ii. A data warehouse provides a centralized view of all data being collected across the enterprise and provides a means <\/i>of<\/i> determining data that is inconsistent.<\/i><\/p>\n

<\/i>iii. Once all data is identified as consistent, an organization can generate one version of the truth. This is important when the company wants to report consistent statistics about itself, such as revenue or number of employees.<\/i><\/p>\n

<\/i>iv. By having a data warehouse, snapshots of data can be taken over time. This creates a historical record of data, which allows for an analysis of trends.<\/i><\/p>\n

<\/i>v. A data warehouse provides tools to combine data, which can provide new information and analysis.<\/i><\/p>\n

12. What is data mining?<\/p>\n

<\/i>a. Data mining is the process of analyzing data to find previously unknown trends, patterns, and associations in order to make decisions. <\/i><\/p>\n

7. What is pretexting?<\/p>\n

<\/i>a. Pretexting occurs when an attacker calls a helpdesk or security administrator <\/i>and pretends<\/i> to be a particular <\/i>authorized user<\/i> having trouble logging in<\/i>. <\/i>Then, by providing some personal information about <\/i>the authorized user<\/i>, <\/i>the attacker<\/i> convince<\/i>s<\/i> the <\/i>security <\/i>person to reset the password and <\/i>tell him what it is<\/i>.<\/i><\/p>\n

8. What are the components of a good backup plan?<\/p>\n

2. Summarize Carr\u2019s argument in \u201cDoes IT Matter.\u201d<\/p>\n

<\/i>a. Information technology is now a commodity and cannot be used to provide an organization with competitive advantage. <\/i><\/p>\n

3. How is the 2008 study by Brynjolfsson and McAfee different from previous studies? How is it the same?<\/p>\n

<\/i>a. It is different because it shows that IT can bring a competitive advantage, given the right conditions. It is the same in <\/i>the sense <\/i>that it shows that IT, by itself, does not bring competitive advantage. <\/i><\/p>\n

4. What does it mean for a business to have a competitive advantage?<\/p>\n

<\/i>a. A company is said to have a competitive advantage over its rivals when it is able to sustain profits that exceed average for the industry. <\/i><\/p>\n

5. What are the primary activities and support activities of the value chain?<\/p>\n

8. Give an example of a semi-structured decision and explain what inputs would be necessary to provide assistance in making the decision.<\/p>\n

<\/i>a. A semi-structured decision is one in which most of the factors needed for making the decision are known but human experience and other outside factors may still play a role. The student should provide an example of a decision that uses an information system to provide information but is not made by the system. Examples would include: budgeting decisions, diagnosing a medical condition, and investment decisions. <\/i><\/p>\n

9. What does a collaborative information system do?<\/p>\n

<\/i>a. A collaborative system is software that allows multiple users to interact on a document or topic in order to complete a task or make a decision.<\/i><\/p>\n

10. How can IT play a role in competitive advantage, according to the 2008 article by Brynjolfsson and McAfee?<\/p>\n

<\/i>a. The article suggests that <\/i>IT can influence competitive advantage when <\/i>good management develops and delivers <\/i>IT-supported <\/i>process <\/i>innovation<\/i>.<\/i><\/p>\n

 <\/p>\n

Chapter 8<\/p>\n

 <\/p>\n

1. What does the term business process<\/i> mean?<\/p>\n

4. What is an ERP system? How does an ERP system enforce best practices for an organization?<\/p>\n

<\/i>a. An ERP (enterprise resource p<\/i>lanning) system is a software application with a centralized database that is implemented across the entire organization. It enforces best practices through the business processes embedded in the software. <\/i><\/p>\n

5. What is one of the criticisms of ERP systems?<\/p>\n

<\/i>a. ERP system<\/i>s<\/i> can lead to the commoditization of business processes, meaning that every company that uses an ERP <\/i>system <\/i>will perform business processes the same way. <\/i><\/p>\n

6. What is business process reengineering? How is it different from incrementally improving a process?<\/p>\n

<\/i>a. Business process r<\/i>eengineering (BPR) occurs when a business process is redesigned from the ground up. It is different from incrementally improving a process <\/i>in that<\/i> it does not simply take the existing process and modify it. <\/i><\/p>\n

7. Why did BPR get a bad name?<\/p>\n

<\/i>a. BPR became an excuse to lay<\/i> <\/i>off employees and try to complete the same amount of work using fewer employees. <\/i><\/p>\n

8. List the guidelines for redesigning a business process.<\/p>\n

<\/i>a. The guidelin<\/i>es are as follows:<\/i> <\/i><\/p>\n

<\/i>i. Organize around outcomes, not tasks. <\/i><\/p>\n

<\/i>ii. Have those who use the outcomes of the process perform the process.<\/i><\/p>\n

<\/i>iii. Subsume information-processing work into the real work that produces the information. Treat geographically dispersed resources as though they were centralized.<\/i><\/p>\n

<\/i>iv. Link parallel activities instead of integrating their results. <\/i><\/p>\n

<\/i>v. Put the decision points where the work is performed, and build controls into the process. <\/i><\/p>\n

<\/i>vi. Capture information once, at the source. <\/i><\/p>\n

9. What is business process management? What role does it play in allowing a company to differentiate itself?<\/p>\n

<\/i>a. Business process management (BPM) can be thought of as an intentional effort to plan, document, implement, and distribute an organization<\/i>\u2019<\/i>s business processes with the support of information technology. It can play a role in differentiation <\/i>through built-in reporting, and <\/i>by empowering employees, enforcing best practices, <\/i>and <\/i>enforcing consistency. <\/i><\/p>\n

10. What does ISO certification signify?<\/p>\n

<\/i>a. ISO certification shows that you know what you do, do what you say, and have documented your processes. <\/i><\/p>\n

<\/i>a. They may wish to build their own in order t<\/i>o have something that is unique (<\/i>d<\/i>ifferent from their competitors),<\/i> <\/i>and\/or <\/i>something that more closely matches their business processes. They also may choose to do this if they have more time <\/i>and\/<\/i>or more money available to do it. <\/i><\/p>\n

6. What is responsive design?<\/p>\n

<\/i>a. Responsive design is a method <\/i>of<\/i> developing <\/i>websites <\/i>that allows <\/i>them<\/i> to be viewed on many different types of devices without losing capability or effectiveness.

<\/i>a. The three eras are as follows:<\/i> <\/i><\/p>\n

<\/i>i. \u201c<\/i>Globalization 1.0<\/i>\u201d<\/i> occurred from 1492 until about 1800. In this era, globalization was centered around countries. It was about how much horsepower, wind power, and steam power a country had and how creatively it was deployed. The world shrank from size <\/i>\u201c<\/i>large<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>medium.<\/i>\u201d<\/i><\/p>\n

<\/i>ii. \u201c<\/i>Globalization 2.0<\/i>\u201d<\/i> occurred from about 1800 until 2000, interrupted only by the two World Wars. In this era, the dynamic force driving change was <\/i>comprised of <\/i>multinational companies. The world shrank from size <\/i>\u201c<\/i>medium<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>small.<\/i>\u201d<\/i><\/p>\n

<\/i>iii. \u201c<\/i>Globalization 3.0<\/i>\u201d<\/i> is our current era, beginning in the year 2000. The convergence of the personal computer, fiber-optic Internet connections, and software has created a <\/i>\u201c<\/i>flat-world platform<\/i>\u201d<\/i> that allows small groups and even individuals to go global. The world has shrunk from size <\/i>\u201c<\/i>small<\/i>\u201d<\/i> to size <\/i>\u201c<\/i>tiny.<\/i>\u201d<\/i><\/p>\n

3. Which technologies have had the biggest effect on globalization?<\/p>\n
