Now answer the questions below: Question 1: The Zara case shows how information systems can impact every single management discipline. Which management disciplines were mentioned in this case and how does technology impact each? (50% of the total mark) The case study mentioned management disciplines including information gathering, processing, storing, distributing and use of information. Gather market information One of the successful factors in Zara is they know the market trends. Zara deploys the latest information technology tools to facilitate the information exchange and collect market data through both formal and informal channels – the PDA and POS systems. The Personal Digital Assistants (PDA) system Zara’s store managers were given personal digital assistants (PDAs) so they could gather customer input outside an office setting. The staff in Zara would regularly gather information from customers, such as the trend of fashion customers preferred and feedbacks of garment that they would like to see more in the shop. The range of information collected included colours, length and even small detail of the clothes were collected from customers through front line shop staff.

The staff will investigate the unsold items that customers tried on but didn’t buy, to find out their preferences in cloth, color, or styles offered among the products in stock. The Point-of-sale (POS) system Besides the informal channel to gather customers needs (through conversations), the head office will collect information through a formal channel, the store’s point-of-sale (POS) system. This system is a transaction process that captures customer purchase information, in order to show how garments rank by sales. Since the POS system is linked with the PDA system, in less than an hour, managers can send updates that combine the hard data captured at the cash register with insights on what customers would like to see. Information on customer needs and trend information collected daily are fed into a database at head office regularly. The PDAs support the connection between the retail stores and head office. Each store managers are assigned with market specialists, they will communicate regularly through PDAs to transmit all kinds of information to head office. [1] Zara store management and staff use PDAs and POS systems to gather and analyze customer preference data to plan future designs based on feedback, rather than prediction. Data driven product development The data collected from PDA as well as POS system formed a valuable marketing database and provided data allows the design teams to plan styles and issue re-buy orders based on feedback rather than hunches and guesswork. The goal is to improve the frequency and quality of decisions made by the design and planning teams. The designers from â€Å"The Cube† follow evidence of customer demand. When they deign new garments or decide which kind of fabric, cut and price points to be used or modify existing designs, they will base on information from PDAs and POS rather than create trends by pushing new lines via advertisements or catwalk fashion shows. Vertically integrated value chain Inditex is a vertically integrated group, it owns several layers in its value chain. The distribution center in La Coruna equipped with up-to-date equipment for fabric dyeing and processing, cutting and garment finishing. The vertically integrated ability allows the group to response faster against the latest fashion trend including provide the appropriate for new lines. Zara’s IT expenditures are low by fashion industry standards. The spectacular benefits reaped by Zara from the deployment of technology have resulted from targeting technology investment at the points in the value chain where it has the greatest impact, and not from the sheer magnitude of the investment. This is in stark contrast to Prada’s experience with in-store technology deployment. Inventory control Zara uses Toyota-designed logistics system and overnight parcel services to manipulate items stocked in the five-million-square-foot distribution center in La Coruna, or a similar facility in Zaragoza in the northeast of Spain. About two and a half million items were handled every week and none of them stayed in the warehouses more than 3 days. Before sending to each store, clothes are ironed in advance and packed on hangers, with security and price tags fixed beforehand. This system helps staff in Zara utilize their time efficiently with the inventory during busy periods. Just-in-time manufacturing (JIT) The JIT approach to manufacturing involves timing the delivery of resources so that they arrive just when needed. Inventory optimization models help the firm determine how many of which items in which sizes should be delivered to each specific store during twice-weekly shipments, ensuring that each store is stocked with just what it needs. Trucks serve destinations that can be reached overnight, while chartered cargo flights serve farther destinations within forty-eight hours. And the firm can coordinate outbound shipment of all Inditex brands with return legs loaded with raw materials and half-finished clothes items from locations out-side of Spain thanks to the revised shipping models through Air France–KLM Cargo and Emirates Air. Zara’s products are manufactured for a limited production run. This approach encourages customers to buy right away and at full price. The constant parade of new, limited-run items also encourages customers to visit often. Staff allocation Headquarter of Zara uses software to arrange staff’s roster. The manpower is allocated based on each store’s forecasted sales volume, with locations staffing up at peak times such as lunch or early evening. The firm claims these more flexible schedules have shaved staff work hours by 2 percent. This constant refinement of operations throughout the firm’s value chain has helped reverse a prior trend of costs rising faster than sales. Zara’s combination of vertical integration and technology-orchestrated supplier coordination, just-in-time manufacturing, and logistics allows it to go from design to shelf in days instead of months. [pic] Question 2: Do you think information systems are a strategic liability for Zara? Give reasons. (50% of the total mark) Porter’s five forces analysis To understand the business condition of fashion industry, we need to use Porter’s five forces model. It is shown how the market behaved at the very beginning of the company according to the Porter’s 5 forces analysis. Bargaining Power of Suppliers This is how much pressure suppliers can place on a business. If one supplier has a large enough impact to affect a company’s margins and volumes, then they hold substantial power. †¢ There are many suppliers for raw material †¢ There are many substitutes †¢ Presence of substitute inputs †¢ The nature of the products allow to storage them long time, unless the trends conditions. Bargaining Power of customers This is how much pressure customers can place on a business. †¢ Switching to another (competitive) product is simple The product is not extremely important to the buyer; they can do without it for a period of time. †¢ Customers are price sensitive †¢ Buyer do not have switching costs †¢ Many availabilities of existing substitute products †¢ Buyer is price and style sensitive †¢ Low purchase volume per customer. †¢ Highly dynamic, customers preference changes frequently in short time Competi tive rivalry within an industry This describes the intensity of competition between existing firms in an industry. Garment industry is highly competitive generally earn low returns. For many industries, this is the major determinant of the competitiveness of the industry. Sometimes rivals compete aggressively and sometimes rivals compete in non-price dimensions such as innovation, marketing, etc. †¢ It is a mature industry with very little growth. Companies can only grow by stealing customers away from competitors. †¢ It has a lot competitors in the industry about the same size †¢ Little differentiation between competitors’ products and services. Key competitors include Gap,, Benetton, H, Forever 21 , etc. Pfeifer, (2008); Rohwedder and Johnson, (2008) H has increased the frequency of new items in stores, Forever 21 and Uniqlo get new looks within 6 weeks and Benetton, a firm that previously closed some 90 percent of US stores, now replenishes stores as fast as once a week †¢ The barriers to get out of the industry are low in distribution and high in manufacture †¢ Since the chances of clothes getting damaged before sold is very little, the storage costs would be low †¢ High manufacture costs because of high raw material cost and manpower cost Threat of new Entrants No distribution barriers to entrance because it only consists on low costs of renting a shop, no administrative restrictions, low initial capital to start †¢ Reduced reaction possibilities in front of new entrants †¢ In production, there are barriers for the existence of economies of scale. †¢ The start up capital needed is high †¢ Need time to build up relationship with supply chain and s uppliers Threat of substitute products What is the likelihood that someone will switch to a competitive product or service? If the cost of switching is low, then this poses to be a serious threat. Buyer can easily found substitute †¢ Relative price performance of substitutes †¢ Buyer switching costs is low †¢ Perceived level of product differentiation †¢ Fad and fashion †¢ Technology change and product innovation The main issue is the similarity of substitutes. For example, if the price of coffee rises substantially, a coffee drinker is likely to switch over to a beverage like tea because the products are so similar. If substitutes are similar, then it can be viewed in the same light as a new entrant. Zara’s success factors The success factors/ competitive advantages include always producing the style that customers are looking for, short production time from design stage and limited quantities. Information system plays strategic liability in the following: Collecting Market Data customer’s needs Product development JIT production Considering the information technology investment helping Zara to maintain it’s competitive advantages, it is strategic liability for the firm.

The effects of Marijuana essays

The effects of Marijuana essays Marijuana can cause many harmful effects. There has never been a major test though. The ones theyve used have shown very different things. I have been very surprised by what I have been reading. I cannot believe the difference in what different scientists think. One says, It's hard to know for sure whether regular marijuana use causes cancer. But it is known that marijuana contains some of the same and sometimes even more, of the cancer-causing chemicals found in tobacco smoke. Studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day. While in certain places it is legally perscribed to people with many different types of cancer. The New scientist says, A FRENCH government study has heaped fuel on the debate over the safety of cannabis by listing it as the least dangerous of all potentially addictive drugs. It also concludes that alcohol is among the most dangerous. The study, commissioned by French health minister Bernard Kouchner, was carried out by a panel of 10 French and foreign scientists headed by Bernard-Pierre Roques of the Ren Descartes University of Paris. The panel searched the scientific literature for information about psychological and physical dependence, neural and general toxicity and social hazards such as aggressive behavior caused by various legal and illegal drugs. The team then grouped the substances into three categories of dangerousness. Cannabis was the only drug put in the least dangerous category. While cautioning that no drug they assessed was "completely free of danger", the researchers gave cannabis a rating of "weak" for social hazard and addictiveness, "very weak" for general toxicity and zero for neurotoxicity. In the most dangerous category, they included heroin and other opiates, and cocaine. Alcohol was also placed in this category because of its stro...

Environmental Studies - Air Pollution Essay Example | Topics and Well Written Essays - 750 words

Environmental Studies - Air Pollution - Essay Example Air pollution also affects the environment in that it causes visibility impairment, damages soil property and structure and most unfortunately, it harms the ozone which in turn changes the structure of the ecosystem Schenelle, Benedict and Alfred say (25), reduces the amount and rate of CO2 by plants .Ozone damage may also cause reduction in biodiversity. Vallero (54) mentioned that biologically, the effects of the air pollution are easily evident among animals who primarily feed on plants that have been affected by the effects of air pollution. The exact direct effect of air pollution on human beings has been hard to measure due to the exposure to other numerous pollution and early medical treatment. Since air pollution is usually in gaseous form it tends to move around easily and globally. Abiotic factors are usually non living things that exist in the environment that affect how living organisms live. Minerals, temperature, salinity, wind, air, light, soil conditions, cloud cover and water availability are some of the examples of the abiotic factors in an ecosystem. Air pollution inevitably affects the cloud cover which in turn regulates the intensity of light penetration to the atmosphere. This affects plants in that they are not able to make food and it also predisposes human beings to rickets. Contaminants in the air specifically carbon dioxide, nitrogen oxides and sulfur dioxide sometimes mix with molecules of water or rain to form acid rain. Acid rain is corrosive in nature, because of this it burns the plants sometimes to complete wither and death. â€Å"This rain also causes corrosion of infrastructure through rust, and weakening them which causes accidents that usually not anticipated†, says Holgate (13). Air pollution also affects the rainfall timing and sequence. Biotic factors are living organisms in the ecosystem. Fungus, bacteria, mammals, plants are some of the examples of ecosystem biotic factors. Air pollution determines which vegetati on grows properly and where. Most animals survive under specific weather conditions, but, air pollution has completely altered the temperature of specific places. Light penetration in aquatic bodies has affected the manner in which aquatic animals thrive in their environment. Human beings are known to release dangerous substances into the air which in turn affects them, animals and plant. Air pollution is becoming a great problem to the human race, especially the elderly and children who have slightly weaker respiratory systems compared to the entire demographic sects. Depletion of the ozone layer, smog presence in the environment and global warming are some of the major human facilitated air pollution as mentioned by Schnelle et al. (63). These adverse effects are known to cause numerous and sometimes rare diseases to human beings. Quite often these diseases are respiratory infections or skin diseases as mentioned by Holgate (35).Human beings are also involved in forums to design n ew rule and technology to reduce air pollution. The current environmental and conservation problems caused by air pollution include: Fossil fuel emission has led to depletion of the ozone layer. Excessive release of poisonous gases has led to destruction of wildlife Death of animals from fluoride toxicity. Respiratory and skin diseases on human beings Chlorosis in plants cause by overexposure to acid rain. Global warming. Deforestation. Some of the measure or steps to be taken to prevent or at least reduce the amount of air
