...Kristen’s Cookie Co. – Katherine Fanola Individual Assignment Question 1: Draw a Flow Diagram Question 2: How long will it take to fulfill a rush order? The answer is 26 minutes. First, the customer will order which will not take any time. Then, Kristen begins by washing and mixing which will have a cycle time of 6 minutes. Next, spooning will take Kristen 2 minutes, leaving a finish time at 8 minutes (6 min+2min). Then Kristen’s roommate will heat the oven which will take 1 minute leaving a finish time of 9 minutes (8 min+1 min). The cookies will bake for 9 minutes leaving a finish time of 18 minutes (9 min+9 min). Time for the cookies to unload and cool down will then be an additional 5 minutes leaving a finish time of 23 minutes (18 min+5 min). Last step is for customer to pay and for the money to be collecting taking a total of 3 more minutes and leaving a finish time of 26 minutes (23 min + 3 min). Therefore, total time to fulfill a rush order is 26 minutes. Question 3: How many orders can you fulfill in a night, assuming you are open for 4 hours each night? The answer is 22 dozen cookies. Operating for 4 hours in a night is equivalent to operating for 240 minutes. If each order size is one dozen cookies, then order completion time for 1 batch will be 26 minutes. Then, the time for every additional dozen of cookies after that will take 10 minutes. It will take 236 minutes for 22 dozen cookies to be ordered in this case, and it will take 246...

Financial Department is using the Master‐Budget Method for their assesment. As seen in the table above, if the 10M€ is divided by the prevision of 200 rooms and after the addition of the variable costs, the Cost would be higher than the 140€ offer that they have received. After this decission, the forecast for the year will need to be adjusted as the occupancy will be lower now; Master‐Budget 10.000.000,00 € 175 156,56 € 13,00 € 169,56 € 2.

It has 741 stores nationally, including 45 BI-LO Supermarkets that also stock Coles private label brands, and more than 100,000 employees. Coles was founded by George James (G.J.) Coles when what was called the "Coles Variety Store" opened on 9 April 1914 in Smith Street in the Melbourne suburb of Collingwood. Expansion to more stores occurred and the chain was regarded as leaders in providing value to Australian shoppers (G. J. Coles learned the retail trade working for his father's "Coles Store" business at Wilmot, Tasmania between 1910 and 1913). Coles' interest in food retailing was spurred in 1958 when it acquired 54 John Connell Dickins grocery stores. It then acquired the Beilby's chain in South Australia in 1959 and 265 Matthews Thompson grocery stores in New South Wales in...

...Looking Beyond The Boundaries – A strategy to gain competitive advantage for the Coles Group of Australia By Aruna Kulatunga MGG9352 Management Processes and Systems. Semester 1, 2007 Looking Beyond The Boundaries – A strategy to gain competitive advantage for Coles Group Executive Summary The Coles Group of Australia has allowed its competitive advantage to slip away to rival Woolworth by failing to differentiate its core strategies and by failing to articulate well the strategies that could have been differentiated. In a bid to gain competitive advantage, this report suggests that the Coles Group should look beyond the company boundaries, extending its value chain to suppliers, partners and customers in a seamless manner, employ process like Total Quality Management and Business Process Reengineering in extending the value chain, bedded in a well structured change management programme and look towards globalisation and franchising along with such counter-intuitive, yet innovative, location strategies such as competitive clustering and saturation marketing to regain its competitive advantage. Page 2 23/10/07 Looking Beyond The Boundaries – A strategy to gain competitive advantage for Coles Group Introduction Strategy gurus Porter (1998, p. 2), Mintzberg (1994), Hamel (1998), Hamel and Prahalad, (1994) Champy and Nohria (1996) and Hammer (quoted in Champy and Nohria, (1996)) agree in principle that in order to meet business needs, specific actions need to be...

...Linkin Park is an American rock band from Agoura Hills, California. Formed in 1996, the band rose to international fame with their debut album Hybrid Theory, which was certified Diamond by the RIAA in 2005 and multi-platinum in several other countries.[1] Their following studio album Meteora, continued the band's success, topping the Billboard 200 album chart in 2003, and was followed by extensive touring and charity work around the world.[2] In 2003, MTV2 named Linkin Park the sixth-greatest band of the music video era and the third-best of the new millennium.[3] Billboard ranked Linkin Park No. 19 on the Best Artists of the Decade chart.[4] The band was recently voted as the greatest artist of '00s in a Bracket Madness poll on VH1.[5] Having adapted nu metal and rap metal to a radio-friendly yet densely layered style in Hybrid Theory and Meteora,[6][7][8] the band explored other genres in their next studio album Minutes to Midnight (2007).[9][10] The album topped the Billboard charts and had the third-best debut week of any album that year.[11][12] The band continued to explore a wider variation of musical types in their fourth album A Thousand Suns (2010), layering their music with more electronic sounds and beats. Their most recent work Living Things (2012) combines musical elements from all of their previous records. The band has collaborated with several other artists, most notably with rapper Jay-Z in their mashup EP Collision Course, and many others on Reanimation.[7]...
