To achieve that, moderate skill level of workers is required. The advantages of batch process are that it allows workers to specialist in specific lobscouse and use the specialist equipment, different batches of different production an be made. On the other hand, there are also disadvantages of batch process. Firstly, specialization means that the workers are doing repetitive jobs, which can result to boredom. Secondly, the machinery needs to be reset and cleaned in between batches. This can be time consuming which in turns slows down the production. Also, when the hamburgers are produced by batches, they would keep them for as long as possible and eventually discard them if they were not sold. This will increase the cost for McDonald’s.

Both companies operate in an international setting and employ a diverse workforce with mixed cultures. Even if these factors hold for both companies, it is a operational wonder how both manage to have sizeable amounts of profit. We will write a custom essay sample on Operations management or any similar topic only for you Order Now For instance, Ford Motors established an automobile park wherein various factories dedicated to specific assembly lines have been established side by side. The factories lie close to the existing 80-year old facility in Southern Chicago. Each facility in this complex puts the assembly line in the various Ford automobiles closer. This strategy copied from low-cost vehicle assembly plants in Latin American countries saves the company up to $15 million annually in lost transportation costs. Before, it takes about a day in order to transport automobile parts from Ford’s component suppliers to the main assembly plant in Southern Chicago. Although initial costs are up to $250-million, the automobile company prioritized the quality of their supplier parts that would now take only 15-minutes in transport from one factory to the other within the park. According to Brown, â€Å"operations have been promising within the park† since it opened in early 2004. On the other hand, operations management innovations in Hard Rock have been similar to that of other companies such as Starbucks. This time though, Hard Rock has been successful in benchmarking itself as a fashionable and trendy bar restaurant serving great food, updated music as well as sold-out events. Hard Rock also became known in recent years by breaking into new territories by opening new Hard Rock Hotels in Bali, Indonesia, Pattaya, Thailand, Las Vegas, Nevada, among others. This has proven that the company amidst stiff competition. In general, Ford and Hard Rock have been perfect examples of how operations management principles can still improve quality even under profit maximizing measures. How to cite Operations management, Essays Operations management Free Essays Introduction Strategic Focus, one amongst the most important step in the design and development of a product, enables companies to discover and explicitly commit themselves to important considerations (Ahoy, 2008). In the current case studies of Ready Materials and Zara, efficient and effective strategic focus assisted in expanding and extending the business into the narrow market or industry segment. More specifically, the super-responsive supply chain developed by Zara permitted the company in designing, producing and delivering new garments for marketing worldwide (Gattorna 1998). We will write a custom essay sample on Operations management or any similar topic only for you Order Now Ready Materials, on the other hand, possessed no clear strategic focus and witnessed complexities in meeting the volatile demand pattern. This characteristic absence of strategic focus caused a demand uncertainty, which eventually led to the emergence of buffering mechanisms (forward load, inventory and capacity). Owing to the fluctuating nature of daily demand, most of the purchasers of Ready Materials have aligned their orders with respect to a day per day operation and waited for the dispatch for an average time of 24 hours. Use of capacity buffering system in the form of annualised hours helped in managing Ready Materials at times of demand fluctuations, enabling adjustments to the working day by up to two hours, either way, without any intimation (Gattorna, 2009). Though these buffering mechanisms caused the company to witness low levels of staff morale and retention, in recent years, this has gained immense attention with the work force finishing the task early more often than late. Buffering mechanisms undertake the forms of order backlogs link with a variable extension to lead time. Inventory buffering mechanism, used by Ready Materials, compressed the customer response time by committing capacity in the advance of demand. Reducing the capital or, in other words, operating at the negative working capital helps in aligning with offsetting the investment in additional capacity. Thus, managing buffering mechanisms through resource alerts and effective prioritisation of resource attention assists projects in taking an advantage. It minimises the impact of Parkinson’s Law, and prevents unnecessary distraction alongside facilitating recovery planning when required, yet at a time in advance when the project or company is in trouble. Presence of high demand uncertainty necessitates the need of project and strategic management (Lake, 2010). As indicated earlier, the use of buffering and alignment mechanisms, allow the resources and companies to gain a st rategic focus of resource attention besides enabling the advantage of good morale and early task finish. Much focus can be levied on time schedule management, and this automatically decreases unnecessary distraction, further enabling for the recovery planning to prevail, when needed. However, this is only necessary whenever the company witnesses extreme difficulty (Ahoy, 2008). Managing of uncertainty remained at the core of improvement of project performance for Ready Materials. Making use of highly sophisticated just in time systems could help in adjusting to the alignment and this automatically offers an efficient strategic focus. At such times, the company is required to get the projects completed both ahead of schedule and with efficient reliability of stock delivery dates that were promised. This specific approach to alignment offers mechanisms which allow a â€Å"complete system† view of projects. The mechanism of alignment recognises and safeguards the uncertainty and thereby avoids the Parkinson’s Law at the task level whilst considering Murphy’s Law at the project stage. All of these implications suggest an intimate interrelationship between strategic focus, buffering and alignment. Effective and efficient management of these three segments of operational management helps each of the companies in driving towards success (Vital e, 2002). It is the duty of project managers to shift their attention from assuring the achievement of strategic focus, task estimates and intermediate milestones. All of these are vital from the date it is required to the final promised due date. But, a grasping of the whole implication of this approach is an immense challenge. Running factories for only a single shift, sending half empty loads to other countries, which were followed by Zara, could help in focusing local efficiency at the expense of international responsiveness. Investing in the overall capital assets can eventually enhance the strategic focus and organisational flexibility (Stratton, 2008). Owing production assets can offer the company a level of control over its schedules and the companies no matter what they intend to do. Besides manufacturing of complicated products, it can enhance strategic focus and thereby minimise the incorporation of buffering mechanisms and alignment patterns. References Ahoy, K. (2008).

How to cite Operations management, Essay examples Operations Management Free Essays Operation management is the activity of managing the resources, such as capital, facilities, raw materials, technology, and so on, which create and deliver services and products. ( Slack et al, 2011 ) No organization could survive in long term if it cannot manage operations management effectively. The importance of operations management is that it affects an organization’s costs. We will write a custom essay sample on Operations Management or any similar topic only for you Order Now There are three activities of operations management, which is directing the overall strategy of the operation, designing the operation’s services, products, and processes, delivering to customer, and developing process performance. IKEA’s History and its Operations Management IKEA was founded in 1943 in Sweden, and it is a successful international retailer with 276 stores in 36 countries. IKEA offers a large variety of well designed furnishing products with low costs, which has contributed to its success. IKEA also contributes a lot to the environment. It cares about the safety of raw materials and production. For example, IKEA stopping selling plastic bags, and it encourage customers to bring their own bags. To support â€Å"less plastic bags† action, IKEA reduced 30 cents each of its own recycle bags. Supply Network Design and Supply Chain Management Most IKEA stores locate outside city centers in order to reduce transportation costs and capital costs. For example, there are two IKEA stores in Singapore, one is in Queenstown, the other one is in Tampines. These two places is not in the city center. Besides, Singapore is a small country that allows IKEA to save more delivery costs comparing with those big countries, such as America. In order to keep the price low, IKEA transports products by truck, rail, and ship. Flat packs and stackable products allows IKEA to handle more of them during delivering. Process Design and Layout Firstly, IKEA’s biggest symbol is its large blue building with yellow shop sign. Secondly, its showroom design is similar to ‘one way’ layout, which makes customers wanna visit the whole store. Thirdly, IKEA provides convenience to customer from free parking, large and clear notice board. IKEA not only offers functional furnishing products, but also restaurant, grocery stores which has majority of Swedish food, and children play area. ( IKEA ‘s Official Website ) Product Design IKEA designs stylish products that can be flat-packed efficiently. ( Slack et al, 2011 ) And it makes products with low costs that are affordable to customers. Customers have to collect the flat-packed goods from the store and assemble those products by themselves. (IKEA also provides delivery service ) In this way, IKEA could reduce labor costs ,storage costs, and shipping costs in order to support its high efficiency. In fact, both customer and IKEA benefit from this concept. IKEA’s has built good relationship with its suppliers. It has suppliers from more than 50 countries and Its purchasing teams are located all over the world and work with them. IKEA insists to work environmental friendly. ( ICMR, 2006 ) IKEA only accept woods from qualified forest which is verified as responsibly managed. According to IKEA’s introduction, it provides collection points for customers to return waste. During manufacturing process, it tries to minimize wastes. IKEA would use the waste to produce other items if possible. In a word, IKEA makes a great effort to use and produce remanufactured and renewable goods. IKEA does a great number of tests of productions every year, and it also has third-party auditors to do the tests also. Since IKEA purchase raw materials in large volume, it enables IKEA to reduce costs. With all these effort, IKEA is able to produce sustainable goods with high quality and low costs. In a way, IKEA does not only save direct costs, but also gain intangible costs, such as good reputation and trustworthiness. Quality Management From operation’s perspective, quality is to meet customers’ expectation. In the customers’ perspective, quality is what they think the product should be. IKEA offers delivery service, assembly service, kitchen installation, sewing service, children service, interest free, gift cards, and return policy. ( IKEA Official Website ) People love IKEA’s products, but dislike the shopping experience because there is always crowded and a long queue in the store. IKEA provides catalogue and brochures to customers, and it creates mobile Apps so that customers could download and read it. Customers can see new products and discount products with price. IKEA creates planning tools for customers, which allow customers plan before they shopping. Customer can do their planning online, and they can also check the stock availability. There is a code with every product, customer can check its availability via its official website. It is not easy to create such visibility to customers. It did help people to understand their need, and avoid crowd. Most important, it saved customers’ time and cost since they do not need to go to the store in person first. Nowadays, people rely on internet more than ever, IKEA should try to make itself and the system more approachable and complete. Effective operations management can bring an organization competitive advantage and profit. IKEA has presented a great example. Only each process can interact effectively, can the organization run smoothly. Reference: 1.

Asim was concerned because in its production of iron reinforcement rods SRM used about 20 tonnes of iron billets every month. Iron billets were being produced in only two locations in Pakistan, Lahore and Karachi. We will write a custom essay sample on Operations Management or any similar topic only for you Order Now For several years SRM had bought iron billets from the supplier in Lahore. Purchases were made on a weekly basis, and the expediting and clerical cost per requisition were Rs1 50 and Rs 33 respectively. Cost of unloading the iron billets into SRM was Rs 8. 30 per tonne 2 of iron billets. The storage space for iron billets at SRM was enough for two months demand with extra leased storage space available at Rs 199. 20/tonne/year. A few months back, Asim had been informed by his purchasing agent that the local supplier had followed his Karachi competitor in announcing a new price structure: 2 US $ 1. 00 = Pak Rs 19. 1. The six metre billets used by SRM weighed about 250 kg each.

SRM now had to deal with the Karachi supplier whose prices were the same as the local supplier, except that they did not include the transportation costs from Karachi. Asim contacted a few transporters in Lahore and found that transportation cost of iron billets from Karachi was Rs 830 per tonne. However, large trucks with 20 tonne capacity were also available at Rs 10,000 per truck. It normally took one week for consignment from Pakistan Steel to reach their destinations in Lahore. Asim wondered what effects these new developments would have on his cost structure. 2 How to cite Operations Management, Essay examples Operations Management Free Essays OPERATIONS MANAGEMENT: as a competitive weapon mks mks@mdi. ac. in http://mks507.
