Las Rosas (LR)


Las Rosas (LR) is a large commercial dairy farm owned and managed by the D'Aremberg family since 1986. It has 3800 cows. LR sells milk, cheese and yoghurts. In 1996, LR started to export some of its dairy products. Profits and cash flow have been improving year on year. LR has no outstanding loans and therefore its current gearing ratio is zero.
LR's unique selling proposition (USP) comes from the organic quality of its products as they are made without chemical additives. The cows' diet does not include hormones and other supplements. The farm's products also meet national and international quality standards.
LR's corporate culture encourages innovation and the use of cell production. To stay ahead of the competition LR has increased its spending on research and development (R\&D) and workers are given the opportunity to create new products, or to add value to existing ones. LR's financial manager, however, believes that the R\&D budget is too high and needs to be cut. He also argues that there are too many legal constraints limiting the development of new products.
LR's management is considering buying El Remanzo, a large sheep farm located nearby. This acquisition will cost $24\$24 million and LR will need to cut its R\&D budget to zero and organize a new loan to finance the takeover. A significant restructuring would need to occur at both LR and El Remanzo to allow both companies to combine resources and knowledge. However, the potential economies of scale experienced by LR could be substantial.
Total capital employed at LR is $45\$45 million.

Smith's Foods Ltd (SF)
Charles Smith and seven friends started a private limited company, Smith's Foods Ltd (SF), to produce ready-made healthy meals for people with diabetes*. Using a cost-plus (mark-up) pricing strategy, SF's mission is to make inexpensive, widely available meals that help diabetics manage their carbohydrate intake accurately.
Despite reliance on inexpensive social media marketing, S F grew rapidly. Due to this rapid growth, however, the quality of its products deteriorated, and a number of its meals were found to contain different quantities of carbohydrate than those stated on the packaging. Negative comments appeared on SF's Instagram page. Charles responded quickly to reassure customers and offered refunds. SF's response led to the company receiving an industry award for ethical behaviour.
Charles introduced flow production to reduce the cost of S F 's meals, which changed S F 's scale of operations and increased its gearing ratio. However, Charles had little business experience of using flow production and problems emerged.
External stakeholders began to look into SF's operations. One supermarket chain, Good Foods (GF), contacted Charles and offered to take over SF, keeping Charles on the board of directors. This takeover would allow SF's meals to be produced at a lower cost and reach a wider target market. GF would also finance research and development into new meals with more carefully controlled carbohydrate levels.
However, SF would close. Negative publicity would be considerable. The remaining shareholders have threatened to launch a new business, creating their own brand of meals for people with diabetes in direct competition with GF.
* diabetes: a medical condition that causes a person's blood sugar level to become too high. People with diabetes need to be mindful of the amount of carbohydrates (which includes sugar) they include in their diet.

Explain one benefit and one cost to S F of using a flow production method.

Item 1: Extract from Beral Courier, a local newspaper

Item 1: Extract from Beral Courier, a local newspaper Rumours of increased violence outside the UWP-protected area were recently confirmed by the office of the local governor. Attacks against vehicles on roads near local towns such as Bosca, Boussena, Gana and Saura have been confirmed by local police. One driver, who was returning from Saura, was seriously injured. In another instance, there was severe damage to a road, causing vehicles to take a different route, which doubled the travel time. The UWP Mission has announced its intention to increase UWP patrols in the area. The impact of the increased violence has had an immediate impact on local Beral shops, which reported shortages of produce.

Item 5: Extract of a memo from Colonel Michael Donovan to General Diane Pierce regarding workforce planning By changing from a traditional construction approach to a cell production approach, the total time taken to complete the hospital can be shortened to 31 weeks. This is one week longer than the original estimate but still six weeks earlier than the traditional approach. In a cell production approach, most of the troops would be divided into cell "teams". Each team would be responsible for the construction of one wing (cell) of the hospital (Alpha, Beta, Charlie, and Delta). Although some tasks would have to be done for the entire hospital (such as painting and cleaning), most tasks will be completed by different cell teams, each building their own wing of the hospital. There are both advantages and disadvantages to this approach.
