Introduction:
Lean manufacturing: Lean manufacturing is a systematic approach of identifying and eliminating waste through continuous improvement, flowing the product at the pull of the customer in pursuit of perfection. Lean manufacturing is a comprehensive approach to eliminating waste from your operation. It is a systematic methodology that uses various tools to achieve the goal of reduced waste. The principle of lean manufacturing is to reduce cost through continuous improvement that will eventually reduce the cost of services and products, thus growing more profits.

Waste: Waste can be defined as a substance or a thing that is no longer useful in a process. Waste is in fact anything that adds cost, but not value to a product. Toyota executive Taiichi Ohno identified seven types of wastes in manufacturing system, namely:
Overproduction- It is considered to be the worst of the wastes, as it multiplies the other 6 wastes and hides your true capability, thereby causing you to make bad decisions such as turn work away or invest in unnecessary additional capacity.
Defects- It is also pure waste as poor quality is produced. Time, energy and materials are consumed needlessly, and even if the customer is not lost, you still need to do the work again.
Inventory- It is the worst of all the 7 wastes. It ties up cash, requires labor, energy and fixed assets to manage it, and moreover it provides a false sense of comfort by hiding problems.
Motion- In terms of ease of elimination and size of improvement impact, the waste of motion ranks very high and is often the target of kaizen.
Process- It means that a process is not necessary or uses more resources then the customers need require.
Transportation- It is quite visible and clearly adds no value, yet by itself not such a huge waste. This waste can shoot up the priority list whenever it increases the…...

...the subject radiate from the central image as branchers, and branches comprise the key word printed on associated line. Topics of lesser importance are also represented as branches attached to higher level branches and the branches from a connected nodal structure. Mind map then can be enhanced and enriched with colors, pictures, codes and dimension to add interest, beauty and individuality. These will in turn aid creativity, memory and specially the recall of information. Tony Buzan in his book mind maps for kids (2003) said that mind maps are the tool of choice to help us to get our memory tuned. Mind maps work so well because they work with two sections of our memory, which are the imagination and association. He said that mind mapping is a special form of note-taking and planning that work with your brain to make it easier for you to remember things. We must use colors and images to help get our imagination whirring and the way we draw them with words or images resting on connecting, curvy lines or branches , that will help our memory make strong associations. Mind maps will help us to make a distinction between our mental storage capacity, moreover,it will assist us to demonstrate our mental storage efficiency, storing data efficiently, and multiplies our capacity. Mind maps may also aid recall of existing memories. By presenting ideas in a radial, graphical, non-liner manner. Its encourage a brainstorming approach to planning and organizational tasks.......

...Abstract - The aim of this paper is to present that how Value stream mapping (VSM) can be applied to restaurant industry and especially fast food sector. The purpose was to identify wastes and how these can be reduced and/or eliminated by the help of value stream. A case study in Pakistan based restaurant has been carried out to illustrate this. A current state value stream map has been developed. Value stream map highlights opportunities to improve wastes and problems along the restaurant supply chain. Results indicated a non value adding steps of 29% at the processing. Value stream can be readily applied to restaurant industry. Keywords – Value stream mapping, Restaurants, Pakistan I. INTRODUCTION The concept of fast food goes back half a century, yet has found its way into the Pakistani market only a decade or so back. With the introduction of many foreign brands finding their way into the country, in the late nineties, the Pakistani market has finally become accustomed to manufacturing and providing service in such a way that goes around the wholesome fast paced scenario. As time has passed, Pakistani restaurants have picked up the technique to play alongside the foreign players. Now we can see that many local brands have established their image on the fact that they provide not only locally designed food, enveloping the fast food concept. Hence we can say that fast food has evolved and redesigned the whole Pakistani restaurant market. In the past five......

...time and cycle time. Thus, it leads to higher cost and more waiting time which is affecting the restaurant’s business. Value Stream Mapping is put into practice at China Wok by first identifying the various steps in the process. Then current state at China Wok will be identified and examined. Discussions/ meetings will be conducted with the workers and manager along with few interviews. Data will be gathered from them. Current State Value Stream Map is developed with the help of the collected data and information. It provides the current steps information, and also the information required to ship the final products (Jones & Womack, 1996). Cycle time and lead times are then calculated. Non-value added and value added activities are also recognized. VSM will be developed by removing the non-value added activities and wastes. Microsoft Excel and Microsoft Visio are used as a part of the research, to draw the current and the future state maps. http://library.semo.edu:3608/ehost/detail?vid=13&sid=239841dc-2435-4355-b159-20a6d0246a0e%40sessionmgr112&hid=121&bdata=JnNpdGU9ZWhvc3QtbGl2ZQ%3d%3d#db=a9h&AN=5531067 http://library.semo.edu:3608/ehost/detail?vid=15&sid=239841dc-2435-4355-b159-20a6d0246a0e%40sessionmgr112&hid=121&bdata=JnNpdGU9ZWhvc3QtbGl2ZQ%3d%3d#db=a9h&AN=22099719 Afridi, I.

...that firms pursuing a single or dominant strategy achieve lower levels of cost saving performance, as compared with firms pursuing a “balanced” approach that emphasizes two or three different strategies in roughly equal measure. Research limitations/implications – This study relies on very limited performance variables, mainly cost reduction. Additional variables that addressed growth and core competence would provide additional insight on the link between outsourcing and performance. Practical implications – Goal intensity is positively related to higher performance on desired outsourcing outcomes. Firms demonstrated greater success in their ability to pursue multiple outsourcing strategies over firms pursuing a single strategy. Originality/value – The link between strategy and outsourcing performance had not been empirically established.

Mapping

...Prof. Arthur Archer 01/13/12 Mapping The author’s definition of mapping goes far and beyond the basic definition of the word. From the first sentence of his paper, James Corner sets up the reader and accurately introduces his intentions of redefining what mapping is; “Mapping is a fantastic cultural project, creating and building the world as much as measuring and describing it.” The introductory paragraph mentions the “agency” of mapping. It is not until later in the reading that one begins to understand what is meant by the “agency”. The intentions become clearer once we define the term agency. The dictionary Merriam-Webster defines the operation as “the capacity, condition, or state of acting or of exerting power” and in an instrumentality sense: “a person or thing through which power is exerted or an end is achieved”. So as Mr. Corner later describes maps have an immense power over us, of how we view the world, what things are important to us, and in turn the maps we create have the power to guide us in certain direction, or from a certain point of view. At times Corner speaks about agency of mapping as if he feels that it should become a field of study as a whole, because of all the different elements that it envelopes; the study of natural processes and historical context to name a few. That the creation of a map should not be simply to record or trace. A map is a collection of data that represents information gathered during mapping. According to Corner a map is......

... Sheryl Smith Argument Mapping PAD 520 Dr. Glenn Starks October 26, 2015 Create an argument map based on the influence diagram presented in Case 1.3 and complete all the criteria provided in the exercise, beginning with claim. Claim: “The U.S. should return to the 55-mph speed limit in order to conserve fuel and save lives. Information: Authorities consider reducing highway speed from 70-mph to 60-mph could reduce gasoline consumption between 2% and 3%. Which would explain the price reduction at least by 10%. With today’s prices at 38 cent a gallon. However, a lower speed limit saves approximately 167,000 barrels of oil per day and would save approximately 6,400 lives a year.” (Dunn, William N. (2012), Para. 3. P. 24). Warrant 1: While reducing the speed limit can increase the fuel efficiency on the vehicles. Backing: Some cars are already made with fuel injection while driven between 30-mph and 60-mph. Mileage will drop noticeably if driven over 65 mph. Slowing down would reduce the amount of gasoline used as well as limitation grants. On a central standpoint these changes will cost less. Warrant 2: Reduced speed limit will also decrease the loss to of aid due to increasing gasoline prices. Backing 2: Reduce the number of victim will also reduce the governments cost of medical care. Objections: Shortening the speed will rise travel time as well as leading to traffic jams on major highways. Claim: “The U.S. should return to the 55-mph speed limit in order to......

...Question #1. Eliminating the queue of work dramatically quickens the time it takes a part to flow through a system. What are the disadvantages of removing those cues? Answer. Eliminating the queue reduces product inventory and limits machine capacity to increase productivity if demand increases. Additionally, removing one machine from the process effectively eliminates equipment redundancy and in the event of equipment malfunction of sole remaining machine will result in the interruption of the manufacturing process. It will be necessary to perform regular maintenance on sole remaining machine to insure it’s in good operating condition and not in danger of catastrophic break-down. Question #2. How do you think the machine operators would react to the change? Answer. It is natural for employees to experience anxiety, concern and frustration with the change in processes and job responsibilities. To help mitigate this it will be necessary for the company to inform and educate the employees in advance of the changes and help them understand the necessity for change. The changes are being implemented to improve productivity and provide the company a competitive advantage in the market-place. Failure to effect these changes could have a profoundly negative impact on company profitability and impact on employees. Additionally, company employees would be included in the analysis of productiy and the identification of process improvements. Including the employees as......
