Buyers need information richness to make informed purchases, and sellers need information reach to properly market and differentiate themselves from the competition.
is the ability of an organization to tailor its products or services to the customers’ specifications.
For example, customers can order M&M’s in special colors or with customized sayings such as “Marry Me.”
occurs when a company knows enough about a customer’s likes and dislikes that it can fashion offers more likely to appeal to that person, say by tailoring its website to individuals or groups based on profile information, demographics, or prior transactions.
Amazon uses personalization to create a unique portal for each of its customers.

the introduction of ebusiness brought about disintermediation
Occurs when a business sells direct to the customer online and cuts out the intermediary.
This business strategy lets the company shorten the order process and add value with reduced costs or a more responsive and efficient service.
steps are added to the value chain as new players find ways to add value to the business process.
Levi Strauss originally thought it was a good business strategy to limit all online sales to its own website. A few years later, the company realized it could gain a far larger market share by allowing all retailers to sell its products directly to customers.
As ebusiness matures it has become evident that to serve certain markets in volume, some reintermediation may be desirable.
refers to the creation of new kinds of intermediaries that simply could not have existed before the advent of ebusiness,
including comparison-shopping sites such as Kelkoo
and bank account aggregation services such as Citibank.12
measures advertising effectiveness by counting visitor interactions with the target ad,
including time spent viewing the ad, number of pages viewed, and number of repeat visits to the advertisement.
Interactivity measures are a giant step forward for advertisers, since traditional advertising methods—newspapers, magazines, radio, and television—provide few ways to track effectiveness.

sometimes referred to as an estore.
An online version of a retail store where customers can shop at any hour. or etailer.
It can be an extension of an existing store such as The Gap or operate only online such as Amazon.com.
There are three ways to operate as a B2C:
3.) pure play
applies to any consumer who sells a product or service to a business on the Internet.
One example is customers of Priceline.com, who set their own prices for items such as airline tickets or hotel rooms and wait for a seller to decide whether to supply them.
The demand for C2B ebusiness will increase over the next few years due to customers’ desire for greater convenience and lower prices.
applies to customers offering goods and services to each other on the Internet.
A good example of a C2C is an auction where buyers and sellers solicit consecutive bids from each other and prices are determined dynamically.
eBay, the Internet’s most successful C2C online auction website, links like-minded buyers and sellers for a small commission.
Other types of online auctions include forward auctions where sellers market to many buyers and the highest bid wins, and reverse auctions where buyers select goods and services from the seller with the lowest bid.
Internet Service Provider (ISP)
is a company that provides access to the Internet for a monthly fee.
Major ISPs in the United States include AOL, AT&T, Comcast, Earthlink, and Netzero, as well as thousands of local ISPs including regional telephone companies.
real time communication
occurs when a system updates information at the same rate it receives it.
Email was a great advancement over traditional communication methods such as the U.S. mail, but it did not operate in real time.
is a service that enables instant or real-time communication between people.
Businesses immediately saw what they could do:
Instant messaging (Iming)
Answer simple questions quickly and easily.
Resolve questions or problems immediately.
Transmit messages as fast as naturally flowing conversation.
Easily hold simultaneous IM sessions with multiple people.
Eliminate long-distance phone charges.
Quickly identifying which employees are at their computers.
converts an audio broadcast to a digital music player.
Podcasts can increase marketing reach and build customer loyalty.
Companies use podcasts as marketing communication channels discussing everything from corporate strategies to detailed product overviews. The senior executive team can share weekly or monthly podcasts featuring important issues or expert briefings on new technical or marketing developments.
web conferencing or webinar
blends videoconferencing with document sharing and allows the user to deliver a presentation over the Web to a group of geographically dispersed participants.
Regardless of the type of hardware or software the attendees are running, every participant can see what is on anyone else’s screen.
Schools use Web conferencing tools such as Illuminate Live to deliver lectures to students, and businesses use tools such as WebEx to demonstrate products.
Web conferencing is not quite like being there, but professionals can accomplish more sitting at their desks than in an airport waiting to make travel connections.
content magement systems (CMS)
help companies manage the creation, storage, editing, and publication of their website content.
CMSs are user-friendly; most include Web-based publishing, search, navigation, and indexing to organize information; and they let users with little or no technical expertise make website changes.
is the scientific classification of organisms into groups based on similarities of structure or origin.
Taxonomies are also used for indexing the content on the website into categories and subcategories of topics. For example, car is a subtype of vehicle. Every car is a vehicle, but not every vehicle is a car; some vehicles are vans, buses, and trucks.
Taxonomy terms are arranged so that narrower/more specific/”child” terms fall under broader/more generic/”parent” terms.
is the set of ideas about how all information in a given context should be organized.
Many companies hire information architects to create their website taxonomies.
A well-planned taxonomy ensures search and navigation are easy and user-friendly. If the taxonomy is confusing, the site will soon fail.

refers to any software whose source code is made available free (not on a fee or licensing basis as in ebusiness) for any third party to review and modify.
Business 2.0 is capitalizing on open source software. Mozilla, for example, offers its Firefox Web browser and Thunderbird email software free. Mozilla believes the Internet is a public resource that must remain open and accessible to all; it continuously develops free products by bringing together thousands of dedicated volunteers from around the world. Mozilla’s Firefox now holds over 20 percent of the browser market and is quickly becoming a threat to Microsoft’s Internet Explorer. How do open source software companies
user contributed content or user generated content
is created and updated by many users for many users. Websites such as Flickr, Wikipedia, and YouTube, for example, move control of online media from the hands of leaders to the hands of users. Netflix and Amazon both use user-generated content to drive their recommendation tools, and websites such as Yelp use customer reviews to express opinions on products and services. Companies are embracing user-generated content to help with everything from marketing to product development and quality assurance.
where buyers post feedback on sellers. eBay buyers voluntarily comment on the quality of service, their satisfaction with the item traded, and promptness of shipping. Sellers comment about prompt payment from buyers or respond to comments left by the buyer. Companies ranging from Amazon to restaurants are using reputation systems to improve quality and enhance customer satisfaction.

is collaborating and tapping into the core knowledge of all employees, partners, and customers. Knowledge can be a real competitive advantage for an organization. The most common form of collective intelligence found inside the organization is knowledge management (KM)
knowledge management (KM)
supports the capturing, organization, and dissemination of knowledge (i.e., know-how) throughout an organization. KMS can distribute an organization’s knowledge base by interconnecting people and digitally gathering their expertise.
consists of anything that can be documented, archived, and codified, often with the help of IT. Examples of explicit knowledge are assets such as patents, trademarks, business plans, marketing research, and customer lists.
is the knowledge contained in people’s heads. The challenge inherent in tacit knowledge is figuring out how to recognize, generate, share, and manage knowledge that resides in people’s heads.
The most common form of collective intelligence found outside the organization is crowdsourcing
The idea that collective intelligence is greater than the sum of its individual parts has been around for a long time

is the practice of expanding your business and/or social contacts by constructing a personal network
Social networking sites provide two basic functions.
The first is the ability to create and maintain a profile that serves as an online identity within the environment.
The second is the ability to create connections between other people within the network.
social networking analysis (SNA)
maps group contacts (personal and professional) identifying who knows each other and who works together.
In a company it can provide a vision of how employees work together.
It can also identify key experts with specific knowledge such as how to solve a complicated programming problem or launch a new product.

describes the collaborative activity of marking shared online content with keywords or tags as a way to organize it for future navigation, filtering, or search.
The entire user community is invited to tag, and thus essentially defines, the content. Flickr allows users to upload images and tag them with appropriate keywords. After enough people have done so, the resulting tag collection will identify images correctly and without bias.
is similar to taxonomy except that crowdsourcing determines the tags or keyword-based classification system. Using the collective power of a community to identify and classify content significantly lowers content categorization costs, because there is no complicated nomenclature to learn. Users simply create and apply tags as they wish. For example, while cell phone manufacturers often refer to their products as mobile devices, the folksonomy could include mobile phone, wireless phone, smart phone, iPhone, BlackBerry, and so on. All these keywords, if searched, should take a user to the same site. Folksonomies reveal what people truly call things

allows users to share, organize, search, and manage bookmarks. Del.icio.us, a website dedicated to social bookmarking, provides users with a place to store, categorize, annotate, and share favorites. StumbleUpon is another popular social bookmarking website that allows users to locate interesting websites based on their favorite subjects. The more you use the service, the more the system “learns” about your interests and the better it can show you websites that interest you.
blog or web blog
is an online journal that allows users to post their own comments, graphics, and video. Unlike traditional HTML Web pages, blog websites let writers communicate—and reader’s respond—on a regular basis through a simple yet customizable interface that does not require any programming.
is the practice of sending brief posts (140 to 200 characters) to a personal blog, either publicly or to a private group of subscribers who can read the posts as IMs or as text messages. The main advantage of microblogging is that posts can be submitted by a variety of means, such as instant messaging, email, or the Web.
Real Simple Syndication (RSS)
is a Web format used to publish frequently updated works, such as blogs, news headlines, audio, and video, in a standardized format. An RSS document or feed includes full or summarized text, plus other information such as publication date and authorship. News websites, blogs, and podcasts use RSS, constantly feeding news to consumers instead of having them search for it. In addition to facilitating syndication, RSS allows a website’s frequent readers to track updates on the site.
the word is Hawaiian for quick) is a type of collaborative Web page that allows users to add, remove, and change content, which can be easily organized and reorganized as required. While blogs have largely drawn on the creative and personal goals of individual authors, wikis are based on open collaboration with any and everybody. Wikipedia, the open encyclopedia that launched in 2001, has become one of the 10 most popular Web destinations, reaching an estimated 217 million unique visitors a month
describes how products in a network increase in value to users as the number of users increases. The more users and content managers on a wiki, the greater the network affect because more users attract more contributors, whose work attracts more users, and so on. For example, Wikipedia becomes more valuable to users as the number of its contributors increases.
is a website or Web application that uses content from more than one source to create a completely new product or service. The term is typically used in the context of music; putting Jay-Z lyrics over a Radiohead song makes something old new. The Web version of a mashup allows users to mix map data, photos, video, news feeds, blog entries, and so on to create content with a new purpose.

three areas of information security
1.) People– authentication and authorization
2.) Data– prevention and resistance
3.) Attacks– detection and response
data prevention and resistance
public key encription
attack: detection and response
intrusion detection software
occurs when organizations use software that filters content, such as emails, to prevent the accidental or malicious transmission of unauthorized information.
Organizations can use content filtering technologies to filter email and prevent emails containing sensitive information from transmitting, whether the transmission was malicious or accidental.
It can also filter emails and prevent any suspicious files from transmitting such as potential virus-infected files.
Email content filtering can also filter for spam, a form of unsolicited email.
scrambles information into an alternative form that requires a key or password to decrypt.
If there were a security breach and the stolen information were encrypted, the thief would be unable to read it.
Encryption can switch the order of characters, replace characters with other characters, insert or remove characters, or use a mathematical formula to convert the information into a code.
public key encryption (PKE)
uses two keys: a public key that everyone can have and a private key for only the recipient
The organization provides the public key to all customers, whether end consumers or other businesses, who use that key to encrypt their information and send it via the Internet. When it arrives at its destination, the organization uses the private key to unscramble it.

If they are missing, the firewall prevents the information from entering the network. Firewalls can even detect computers communicating with the Internet without approval.
scans and searches hard drives to prevent, detect, and remove known viruses, adware, and spyware. Antivirus software must be frequently updated to protect against newly created viruses.
intrusion detection software (IDS)
eatures full-time monitoring tools that search for patterns in network traffic to identify intruders. IDS protects against suspicious network traffic and attempts to access files and data.
If a suspicious event or unauthorized traffic is identified, the IDS will generate an alarm and can even be customized to shut down a particularly sensitive part of a network.
After identifying an attack, an MIS department can implement response tactics to mitigate the damage.

is the ability to get a system up and running in the event of a system crash or failure that includes restoring the information backup.
is the ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service.
For example, fault tolerance enables a business to support continuous business operations if there is a power failure or flood.
Fault tolerance is an expensive form of backup, and only mission-critical applications and operations use it.
a specific type of fault tolerance, occurs when a redundant storage server offers an exact replica of the real-time data, and if the primary server crashes, the users are automatically directed to the secondary server or backup server.
This is a high-speed and high-cost method of backup and recovery.
occurs when the primary machine recovers and resumes operations, taking over from the secondary server.
backup and recovery plan
able to recover information or systems in the event of a catastrophic disaster such as a fire or flood
business continuity planning
creates a way for a company to recover and restore partially or completely interrupted critical functions within a predetermined time after a disaster or extended disruptions
disaster recovery plan
which is a detailed process for recovering information or a system in the event of a catastrophic disaster. This plan includes such factors as which files and systems need to have backups and their corresponding frequency and methods along with the strategic location of the storage in a separate physical site that is geographically dispersed. A company might strategically maintain operations in New York and San Francisco, ensuring that a natural disaster would not impact both locations. A disaster recovery plan also foresees the possibility that not only the computer equipment but also the building where employees work may be destroyed
is a separate and fully equipped facility where the company can move immediately after a disaster and resume business.
is a separate facility that does not have any computer equipment but is a place where employees can move after a disaster.
is a separate facility with computer equipment that requires installation and configuration.
disaster recovery cost curve
(1) the cost to the company of the unavailability of information and technology and
(2) the cost to the company of recovering from a disaster over time.
the best recovery plan in terms of cost and time is where the two lines intersect. Creating such a curve is no small task. Managers must consider the cost of losing information and technology within each department or functional area, and across the whole company.
business continuity planning (BCP)
which details how a company recovers and restores critical business operations and systems after a disaster or extended disruption.
This plan includes such factors such as identifying critical systems, business processes, departments, and the maximum amount of time the business can continue to operate without functioning systems.
The plan will even detail the order in which functional areas should be restored, ensuring the most critical are focused on first.
refers to the varying levels that define what a user can access, view, or perform when operating a system. Imagine the people at your college accessing the main student information system. Each person that accesses the system will have different needs and requirements;
for example, a payroll employee will need to access vacation information and salary information, or a student will need to access course information and billing information.
or unrestricted access to the entire system. Administrator access can perform functions such as resetting passwords, deleting accounts, and shutting down entire systems.
maintainability or flexability
efers to how quickly a system can transform to support environmental changes. For example, when starting a small business you might not consider that you will have global customers, a common mistake. When building your systems, you might not design them to handle multiple currencies and different languages, which might make sense if the company is not currently performing international business. Unfortunately, when the first international order arrives, which happens easily with ebusiness, the system will be unable to handle the request because it does not have the flexibility to be easily reconfigured for a new language or currency. When the company does start growing and operating overseas, the system will need to be redeveloped, which is not an easy or cheap task, to handle multiple currencies and different languages.
refers to the ability of an application to operate on different devices or software platforms, such as different operating systems. Apple’s iTunes is readily available to users of Mac computers and also users of PC computers, smart phones, iPods, iPhones, iPads, and so on. It is also a portable application.
reliability (or accuracy)
ensures a system is functioning correctly and providing accurate information. Inaccuracy can occur for many reasons, from the incorrect entry of information to the corruption of information during transmissions. Many argue that the information contained in Wikipedia is unreliable.
describes how well a system can scale up, or adapt to the increased demands of growth. If a company grows faster than anticipated, it might experience a variety of problems, from running out of storage space to taking more time to complete transactions. Anticipating expected, and unexpected, growth is key to building scalable systems that can support that development.
measures how quickly a system performs a process or transaction. Performance is a key component of scalability as systems that can’t scale suffer from performance issues. Just imagine your college’s content management system suddenly taking five minutes to return a page after a button is pushed.
determines future environmental infrastructure requirements to ensure high-quality system performance. If a company purchases connectivity software that is outdated or too slow to meet demand, its employees will waste a great deal of time waiting for systems to respond to user requests.
is the degree to which a system is easy to learn and efficient and satisfying to use. Providing hints, tips, shortcuts, and instructions for any system, regardless of its ease of use, is recommended.
which refers to the computer chip performance per dollar doubles every 18 months. Although Moore originally assumed a two-year period, many sources today refer to the 18-month figure.
three pressures driving sustainable MIS infrastructures
1.) increased electronic waste
2.) increased energy consumption
3.) increased carbon emissons
is a collection of computers, often geographically dispersed, that are coordinated to solve a common problem. With grid computing a problem is broken into pieces and distributed to many machines, allowing faster processing than could occur with a single system.
delivers electricity using two-way digital technology. It is meant to solve the problem of the world’s outdated electrical grid, making it more efficient and reliable by adding the ability to remotely monitor, analyze, and control the transmission of power.
refers to the use of resources and applications hosted remotely on the Internet. The term comes (at least in part) from the image of a cloud to represent the Internet or some large networked environment.
offers a pay-per-use revenue model similar to a metered service such as gas or electricity. Many cloud computing service providers use utility computing cloud infrastructures,
infrastructure as a Service (IaaS
is a service that delivers hardware networking capabilities, including the use of servers, networking, and storage over the cloud using a pay-per-use revenue model. With IaaS the customer rents the hardware and provides its own custom applications or programs. IaaS customers save money by not having to spend a large amount of capital purchasing expensive servers, which is a great business advantage considering some servers cost more than $100,000.
which means the MIS infrastructure can be automatically scaled up or down based on needed requirements.
software as a Service (SaaS)
delivers applications over the cloud using a pay-per-use revenue model.
Platform as a Service (PaaS)
supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model. PaaS is a perfect solution for a business as it passes on to the service provider the headache and challenges of buying, managing, and maintaining Web development software. With PaaS the development, deployment, management, and maintenance is based entirely in the cloud and performed by the PaaS provider, allowing the company to focus resources on its core initiatives.
creates multiple “virtual” machines on a single computing device. A good analogy is a computer printer. In the past you had to purchase a fax machine, copy machine, answering machine, and computer printer separately. This was expensive, required enough energy to run four separate machines, not to mention created additional amounts of ewaste.
is a facility used to house management information systems and associated components, such as telecommunications and storage systems. Data centers, sometimes referred to as server farms, consume power and require cooling and floor space while working to support business growth without disrupting normal business operations and the quality of service.
