- Downtime refers to a period of time when a system is unavailable - Costs of downtime are not only associated with lost revenues, but also with financial performance, damage to reputation, and even travel or legal expenses - Reliability and resilience of IT systems have never been more essential for business success

Organizations must enable employees, customers, and partners to access information electronically. You should know that the biggest issue surrounding information security is not a technical issue, but a people issue. The first line of defense an organization should follow to help combat insider issues is to develop information security policies and an information security plan.

- Information security policies identify the rules required to maintain information security, such as requiring users to sign off before leaving, never sharing passwords, and changing passwords every 30 days - Information security plan details how an organization will implement the information security policies - The best way for a company to safeguard itself against people is by implementing and communicating its information security plan - This becomes even more important with Web 2.0 and the use of mobile devices, remote workforce, and contractors are growing

You should understand the importance of decision making for managers at each of the three primary organization levels (strategic, managerial, operational).

- Strategic level - unstructured decisions - managers develop overall business strategies, goals, and objectives as part of the company's strategic plan - Unstructured decisions occur in situations in which no procedures or rules exist to guide decision makers toward the correct choice - Related to the long-term business strategy of the firm o Example: decision about entering a new market over the next 3 years - Managerial level - semi-structured decisions - employees are continually evaluating company operations to hone the firm's abilities to identify, adapt to, and leverage change - Semi-structured decisions occur in situations in which few established processes help to evaluate potential solutions, but not enough to lead to a definite recommended decision - Example: decision about producing new products or changing employee benefits - Operational level - structured decisions - employees develop, control, and maintain core business activities required to run the day-to-day operations - Structured decisions arise in situations where established processes offer potential solutions - Example: decision about reordering inventory or creating the employee staffing and weekly production schedules

You should understand what a supply chain is, and recognize how efficient and effective supply chain management can reduce the power of market forces and affect strategy (p. 215), and understand the importance of IS in supporting supply chain management.

- Supply chain - all parties involved, directly or indirectly, in obtaining raw materials or a product - Supply chain management (SCM) - the management of information flows between and among activities in a supply chain to maximize total supply chain effectiveness and corporate profitability - Supply chain is an intricate network of business partners linked through communication channels and relationships - Supply chain management systems manage and enhance these relationships with the goal of creating a fast, efficient, and low-cost network for business relationships that take products from concept to market - Efficient and effective supply chain management systems can enable an organization to have these effects on Porter's five forces: - Decrease the buyer power and increase supplier power - Increase buyer's switching costs to reduce the threat of substitute products and services - Create entry barriers to reduce the threat of new entrants - Increase efficiencies while seeking a competitive advantage through cost leadership - Procurement - the purchasing of goods and services to meet the needs of the supply chain - Supported by 3D printing - Logistics - includes the processes that control the distribution, maintenance, and replacement of materials and personnel to support the supply chain - Supported by RFID and drones - Materials management - includes that activities that govern the flow of tangible, physical materials through the supply chain, such as shipping, transport, distribution, and warehousing - Supported by robotics - focuses on creating artificial intelligence devices that can move and react to sensory input

You should understand the challenges and risks inherent in system development projects. You should be able to discuss the causes of these failures (refer to pp. 267). You need not know all the details of each phase of the SDLC, but should know, in broad strokes, what goes in in each phase.

- Systems development life cycle (SDLC) - the overall process for developing information systems, from planning and analysis through implementation and maintenance - Phase 1: Planning - establishes a high-level plan of the intended project and determines project goals - Phase 2: Analysis - the firm analyzes its end-user business requirements and refines project goals into defined functions and operations of the intended system - Phase 3: Design - establishes descriptions of the desired features and operations of the system, including screen layouts, business rules, process diagrams, pseudo code, and other documentation - Phase 4: Development - takes all the detailed design documents from the design phase and transforms them into the actual system - Phase 5: Testing - brings all the project pieces together into a special testing environment to eliminate errors and bugs and verify that the system meets all the business requirements - Phase 6: Implementation - the organization places the system into production so users can begin to perform actual business operations with it - Phase 7: Maintenance - the organization performs changes, corrections, additions, and upgrades to ensure the system continues to meet business goals - Primary reasons projects fail: - Unclear or missing business requirements - business requirements drive entire systems and if they are not accurate they will not be successful - Skipped phases - Changing technology - technology changes so fast that is it almost impossible to deliver an information system without having to update it - The cost of finding errors - if an error is found in the testing or implementation phase, it is going to cost a lot to fix because the organization has to change the actual system - Balance of the triple constraints (time, resources, scope) - if any one of these variables changes, then at least one other is likely to be affected

You should be able to describe the information age and the differences between data, information, business intelligence, and knowledge.

- The information age is the present time, during which quantities of facts are widely available to anyone who can use a computer - Data are raw facts that describe the characteristics of an object or event - Information is data converted into a meaningful and useful context - BI is information collected from multiple sources that analyzes patterns, trends, and relationships for strategic decision making - Knowledge is the skills, experience, and expertise, coupled with information and intelligence, that create a person's intellectual resources

You should be able to describe how the evolution of the web progressively enhanced business collaboration tools. While you need not know the details of all the technologies described in the chapter, you should be able to recognize appropriate uses of the most common tools and be able to compare them. These common tools are email and texting, which you should already be familiar with, plus blogs, wikis, and social media, which are listed as key terms.

- The network effect describes how products in a network increase in value to users as the number of users increases - Web 1.0 included email - The evolution from Web 1.0 to Web 2.0 allowed for user-contributed content, allowing for blogs, wikis, social networks - Social networks allow for tagging and social bookmarking - Blogs are online journals that allow users to post their own comments, graphics, and video - A wiki is a type of collaborative web pages that allows users to add, remove, and change content, which can be easily organized and reorganized as needed - Mashups are websites that use content from more than one source to create a completely new product or service - Web-conferencing blends videoconferencing with document sharing and allows the user to deliver a presentation over the web to a group of geographically dispersed participants - Videoconferencing allows people at two or more locations to interact via two-way video and audio transmissions as well as share documents - Can increase productivity because users participate without leaving their offices - Podcasting converts an audio broadcast to a digital music player - Can increase market reach and build customer loyalty - Email allows people to inform and communicate with many others simultaneously, immediately and with ease - Instant messaging enables instant or real-time communication between people

You should understand the meaning of Figure 4.13 as it relates to information security. Remember, this isn't really about itemizing lists. Instead, the concepts around each of these areas and what makes them unique from one another.

- Three areas of information security include: - People - Authorization and Authentication - Data - Prevention and Resistance - Attacks - Detection and Response 1) People - Authentication is a method of confirming users' identities - Authorization is the process of providing a user with permission including access levels and abilities - Authentication and authorization techniques fall into three categories; the most secure procedures combine all three - Something the users knows - user ID and password - Something the user has - smart card or token - Something that is part of the user - fingerprint and voice signature 2) Data - Content filtering occurs when organizations use software that filters content to prevent accident or malicious transmission of unauthorized information - Encryption scrambles information into an alternative form that requires a key or password to encrypt - Many companies have a private decryption key and give customers a public encryption key - Firewalls are hardware/software that guard a private network by analyzing incoming and outgoing information for the correct markings 3) Attacks - Intrusion detection software (IDS) features full-time monitoring tools that search for patterns in network traffic to identify intruders

You should be able to explain that untethered connectivity, anytime, anywhere, has fueled a major market and technology disruption, which has permeated almost every consumer market worldwide. The student will further expound that the "domino effect" of the success of wireless technology has resulted in a unique opportunity for innovation and creativity in technology, marketing, and business strategy.

- Untethered connectivity, anytime, anywhere, has fueled a major market and technology disruption - The success of wireless technology has resulted in a unique opportunity for innovation and creativity in technology, marketing, and business strategy - Three business applications taking advantage of wireless technologies include RFID, GPS, and GIS - RFID allows for asset tracking which allows a company to focus on its supply chain, reduce theft, identify the last known user of assets, and automate maintenance routines - Companies that deal in transportation combine GISs with database and GPS technology to plot routes with up-to-the-second information about the location of all their transport vehicles - GIS is also good at finding patterns - IT consumerization is the blending of personal and business use of technology devices and applications - Is having a huge impact on corporate MIS departments because they must determine how to protect their networks and manage technology that they did not authorize or recommend - Mobile device management tools enforce policies, track inventory, and perform real-time monitoring and performing

You should be able to describe the importance and methods to represent data in a visual format.

- Use visual representations so the data can be more easily understood - Infographics present the results of data analysis, displaying the patters, relationships, and trends in a graphical format - Great data visualizations provide insights into something new about the underlying patterns and relationships - Data visualization describes technologies that allow users to see or visualize data to transform information into a business perspective - Powerful way to simplify complex data sets by placing data in a format that is easily grasped or understood far quicker than the raw data alone - Helps people make decisions faster - Data visualization tools move beyond Excel graphs and charts into sophisticated analysis techniques such as controls, instruments, maps, time-series graphs, etc. - Can help uncover correlations and trends in data that would otherwise go unrecognized - Business Intelligence Dashboards track corporate metrics such as CSFs and KPIs and include advanced capabilities such as interactive controls, allowing users to manipulate data for analysis

You should understand that the Internet is a "network of networks" and the web is just one applications that uses it. The worldwide web is a dominant application, and it underlies many modern technologies, but the term "web" has become much broader in common use and is casually used to describe many things that don't use web technology. For example, the IoT and Web 3.0 are not about web pages.

- WWW is just one part of the Internet and its primary use is to correlate and disseminate information - Uses web browser to find information - Internet includes the WWW and other forms of communication systems like email - Mostly infrastructure - Web 1.0 - users of a website are passive; only owners control content - Extended the reach of many businesses to global markets - Web 2.0 - user-contributed content; collaboration inside and outside of an organization; content sharing through open sourcing; reputation system - Technical skills are no longer required to use and publish information on the WWW, eliminating entry barriers for online businesses - Web 3.0 - machine-based learning and reasoning; semantic web - Offers a way for people to describe information such that computers can start to understand the relationships among concepts and topics

You should understand why the SDLC was originally implemented as a waterfall method and how Agile seeks to improve on waterfall. You should understand the concept of iterative development, and how advances in technology have made it more practical (e.g., effective prototyping).

- Waterfall methodology - a sequence of phases in which the output of each phase becomes the input for the next - In the SDLC, this means that the steps are performed one at a time, in order - No longer serves today's development efforts because it is inflexible, expensive, and requires rigid adherence to the sequence of steps - Prototyping is a modern design approach where the designers and system users use an iterative approach to building the system - Discovery prototyping builds a small-scale representation or working model of the system to ensure it meets the user and business requirements - Iterative development - consists of a series of tiny projects - Has become the foundation for multiple agile methodologies - Agile methodology - aims for customer satisfaction through early and continuous delivery of useful software components developed by an iterative process using the bare minimum requirements - Fast and efficient with lower costs and fewer features - Helps refine feasibility and supports the process for getting rapid feedback as functionality is introduced - Four forms: rapid prototyping, extreme programming methodology, RUP methodology, scrum methodology

You should understand the usefulness of workflow control systems, BPMN, and analytics to business process improvement.

- Workflow control systems monitor processes to ensure tasks, activities, and responsibilities are executed as specified - BPMN is a graphical notation that depicts the steps in a business process - Business process improvement attempts to understand and measure the current process and make performance improvements accordingly
