More than 170 organizations and individuals provided feedback as part of the consultation process.

Why has PRINCE2 been refreshed? PRINCE2 is often cited as the world’s most widely used project management method. Its success is largely due to it being non-proprietary but also due to the ability of organizations to apply it to a variety of industries, environments and project sizes.

...Overview Founded in 1999, Blue Nile had grown to become the largest online retailer of certified diamonds and fine jewelry, with sales of \$203.2 million in 2005 (up from \$169.2 million in 2004). According to Internet Retailer Magazine, in 2006 Blue Nile was larger than the next three largest online jewelers combined; the magazine had ranked Blue Nile No. 48 in its Top 400 Guide to Retail Web Sites; in its December 2006 issue, the magazine went a step further and named Blue Nile an Internet Retailer Best of the Web 2007 company (one of five companies cited). In 2006, the market for jewelry in the U.S. was an estimated \$55-\$60 billion industry. Annual sales of diamond jewelry were in the \$30-\$35 billion range, with diamond engagement rings accounting for sales of \$4-\$5 billion. In an industry famous for big markups, frequent closeout sales, and myriad judgments of value that often mystified consumers, the marketing challenge for online jewelers was to convince understandably skittish shoppers to purchase fine jewelry online. It was one thing to shop for a diamond in a reputable jewelry store where one could put on a ring or other jewelry item to see how it looked, perhaps inspect a stone with a magnifying glass or microscope, and have a qualified jeweler describe the features of various stone(s) and cuts, compare the character and merit of various settings, and explain why some items carried higher price tags than others. It was quite another thing to commit to......

...History of English Literature Overview Anglo-Saxon Literature (500-1100) The Angles and Saxon conquered what is now called England in the 5th and 6th centuries. Christian missionaries taught the English to write. Northumbria soon produced Caedmon and Bede. Heroic poetry of a Christian kind is the chief legacy of Old English literature, notably Beowulf and the Elegies. A considerable prose literature grew up after King Alfred. Middle English Literature (1100-1500) Literature in England in this period was not just in English and Latin but in French as well and developed in directions set largely in France. Epic and Elegy gave way to romance and Lyric. English writing revived fully in English after 1360 and flowered in the reign of Richard II (1372-99). It gained a literary standard in London English after 1425 and developed modern forms of verse, prose and of Drama. The conquest of England in 1066 by William of Normandy displaced English as medium of literature. The language of new rulers was French. Saxons dealing with the King had to learn French and French was the language of court and the law for three centuries. Four genres of Middle English are: i. 1. Fabliau 2. Lyric 3. Dream Allegory 4.

...Week 2 Reflection Summary Team A BIS/220 October 23, 2013 Chris Miserendino Week 2 Reflection Summary There are many data management issues that need to be considered when dealing with new data, transferring data, or just storing data for long periods of time. For instance, if a corporation or business needs to store data for long periods of time, they may have to come up with multiple ways of storing the data in the event one device or method fails. Also, all things eventually wear out in time. Therefore, servers, hard drives, databases and any other technological data storing equipment or methods, must be constantly upgraded or maintained to prevent data rot and equipment failures. Networks, communications, collaborations, databases, data sources, and applications are all related in that they are all used interchangeably. They each have their own purposes or applications. The means of accessing and using the desired information is what differentiates one from the other. For example, databases are used to centralize information that may consist of various degrees of information of reduced specifications and details. Databases also make it possible for employees and employers to access many sources of information from one place, rather than having to use different devices, channels, or methods of accessing information from different places. A database also allows access from various devises, such as computers, phones, and tablets. This allows for multiple......
