A Crisis at Hafford Furniture: Cloud Computing Case study MMBA 507 Student ID: 300333323 PROBLEM DESCRIPTION Hafford Furniture was a furniture manufacturer since 1970, supplying to furniture retailers, wholesalers and occasionally one-time bulk purchasers across the United States. Hafford relied on a Business Information System (BIS) to handle all the internal business processes. The BIS was seamlessly connected to a VAN-based EDI system, which served as the customer’s interface for making orders. In 2008, Hafford’s entire IT infrastructure and data storage were destroyed by a massive hurricane. Hafford was able to restore the company data with its disaster recovery plan, but not all its IT function. In March 2009, VP of IT proposed in a management meeting to adopt SaaS cloud solution to restore the IT function. Hafford could access to the same BIS without having to worry about the cost to rebuild another IT data centre. He projected that the IT staff strength could be halved, as the cloud vendor would take care of the management of the software’s platform and its infrastructure.

In January 2010, Hafford was faced with appalling sales report for the year before, mostly caused by bottlenecks in the ordering system supported by PFI. Not only was the cloud capability insufficient, PFI was also filing for bankruptcy and undergoing liquidation. Hafford once again fell into a desperate situation. REVIEW OF KEY ISSUES Management issues Lack of Corporate governance The weak corporate governance in Hafford is especially notable in the fundamental change process. While there was an internal policy for creating a fundamental change in Hafford (Fig 1), Feckle, the President, had ignored it by entering into a cloud contract without consulting any of his top management, just one day after the premature proposal was shared with him. It was extremely risky to make such a significant business decision without sufficient knowledge in the service that he engaged. To make a well-informed decision, Feckle should have adhered to the corporate policy and trusted the IT professionals to evaluate and recommend a suitable vendor. Figure 1 Fundamental change policy 2. Failure to think critically during decision-making It is understood that Hafford used to adopt a VAN-based EDI-system specifically due to its security, despite it being slower and more costly. In Norris’ proposal for using cloud, he altered the company’s priority by pushing for an internet-based EDI-system, without providing solid justification. Questions like â€Å"will the internet-based EDI change the business in any way?† or â€Å"will it compromise customers’ security? † were not asked. The management seemed to have accepted this change too easily, without understanding its impacts. This concern should have been analysed more thoroughly before concluding to transit to an internet-based EDI-system. 3. Poor understanding of business needs The IT obj ective was not fully aligned with the business objectives. For example, in 2009, while the company was expecting a 30-35% increase in sales due to the efforts in a series of product improvements, the IT team was preparing a cloud proposal to the company basing only on the old IT functions. It had missed out on considering how it could support an explosive sales surge. Furthermore, Hafford was switching its VAN-based EDI to an internet-based EDI, which could potentially allow Hafford to widen its reach to attract a new group of SME customers. This could play a part in increasing their sales. However, Hafford did not foresee these changes, likely due to lack of communication between departments within Hafford. IT issues 1. Lack of thorough analysis in cloud computing The IT team failed to conduct due diligence in exploring all possible solutions that could meet its needs. While cloud offered great advantages for the company, it might have been too hasty to consider only private cloud as the final solution. In fact, public, private or hybrid cloud offered different potentials and could achieve the goal within competitive cost as well. The IT team should also have analysed each cloud model against its business needs before determining if software as a service (SaaS), platform as a service (PaaS), infrastructure as a service (IaaS) or a combination of services would work best. 2. Lack of on-going management While cloud is said to be flexible, it demands some level of active management to harness the most of it after implementation. The IT team should be able to react quickly to resolve problems like the order bottleneck or a data lock-in. Besides, the IT team should have been more vigilant in ensuring business continuity for the company. RECOMMENDATION The key failure observed in the case was the lack of understanding in cloud computing and the lack of communication in the company. Like any other business decisions, the management should have exercised prudence by developing clear objectives and analysing the opportunities and threats before arriving at its conclusion. In this section, a recommended methodology to approach Hafford’s IT restoral problem is presented. Step 1. To develop business objectives The most important step is to approach a business problem with a clear business objective. It will be necessary for the management to look at the restoral of the IT centre as a collaborative business problem. Communication within the organisation is crucial in aligning all the stakeholders’ goals. With effective teamwork, the IT will appreciate the business values better and be able to analyse the suitability of various options. Step 2. To compare various viable options The IT team should research on what the available solutions are, before zeroing into a particular infrastructure option. While the restoral of a physical data centre may be expensive, there may be payment structures that could help reduce the impact. On the other hand, cloud computing may appear cheaper but it inextricably exposes users to a range of risks, especially in the aspect of security. Also, there are hybrid options that can minimise risk while offering cost benefit. In short, the IT team should fully understand the merits and shortcomings of the following options before selecting the IT infrastructure. 1. Public cloud 2. Hybrid cloud 3. Private cloud 4. Public cloud – Physical data centre 5. Physical data centre Step 3. To choose the suitable cloud service model There are three common service models in cloud computing. It is important to evaluate each model’s attributes and determine which cloud model would be more suitable for the business needs. 1. Software as a service (SaaS) To understand threats and opportunities of cloud computing Cloud computing offers the following powerful advantages but also opens a gateway to a wide range of threats. 1. Elasticity Usage-based pricing model, charging users only for the capacity used Scalability in terms of network and speed depending on demand 2. Simplicity Setting up and maintaining a data centre can take significant manpower. Cloud computing offers convenient and economical business solutions to clients, while taking advantage of the economy of scale by taking care of one specialised area in bulk. 3. Cost-efficiency No capital cost required. Companies benefit from the transference of risk (of over-provisioning and under-provisioning) of investing in a private data centre. While accepting these benefits from cloud, users should also exercise due diligence by being aware of all the possible problems cloud computing brings. Some of the crucial problems are outlined as follows. 1. Business continuity There is always a risk with placing valuable business information with a single third party. As such, the best way to go about is to even out the risk by employing multiple cloud providers and devising a business continuity strategy should any of them fail. Data lock-in It would be risky for a company to be unable to easily extract their data and programmes from one cloud provider to another due to compatibility issues of the programme and data from one cloud provider. In order to mitigate this risk, SaaS developer could use standardised API so that the business can remain flexible and mobile. 3. Data security While most cloud providers invest a considerable amount of attention on managing security, users should assess the security standards adopted by the cloud provider against their requirements before engaging it. 4. Insufficient capacity Although it is said that cloud is scalable, in rare occasions, businesses may experience traffic surges beyond what their contracted cloud can offer. Hence, it is important to strategize carefully before deciding on the cloud service. Step 5. Choosing the cloud vendor After thorough analysis and establishing a clear description for the cloud service needed, the user will have to evaluate the following factors to arrive at the most suitable vendor. 1. Pricing structure While cloud vendors typically follow a pay-as-you-use pricing model, pricing structure varies. For example, Google AppEngine charges users by the cycles used while AWS charges by the hour for the number of instances the user occupied. 2. Security Users need to look at a cloud service’s physical as well as network security. This refers to the physical location the cloud provider houses its equipment and network security measures like firewall and data encryption. Also, a cloud provider should be compliant to government standards specific to your business. In the case of Hafford Furniture, it was an auditing requirement for Hafford to ensure the cloud vendor is compliant with Statement on Auditing Standard No.70. 3. Other factors A clean record does not promise anything, it would be beneficial to also look at the vendor’s track record against available benchmark systems. Also, it would be helpful to have a vendor that can provide reasonably good service. Hence, it is important to know about the extent of customer support services, the setting up process and the ser vicing response and resolution time. Step 6. Engagement of cloud vendor and getting started During cloud rollout, especially from a different sort of data management, it would be common to face various teething problems. Cloud vendor should try to achieve seamless implementation, and companies might need to prepare their staff and/or customers should it affect their routine jobs significantly. Step 7. On-going active management of the cloud service Internal IT team should be continuously vigilant towards possible threats to ensure that the cloud service adopted by the company is safe and secure. Active backups of data must not be neglected. Also, internal feedback reviews could help the IT team understand the possible difficulties faced by the users, and also stay up to date with the company’s business initiatives.

Chinas Three Sovereigns and Five Emperors

Chinas Three Sovereigns and Five Emperors Back in the earliest mists of recorded history, over four thousand years ago, China was ruled by its very first dynasties: the mythical Three Sovereigns and Five Emperors. They ruled between about 2852 and 2070 BCE, before the time of the Xia Dynasty.   Legendary Reigns These names and reigns are legendary more than they are strictly historical. For example, the claim that both the Yellow Emperor and Emperor Yao ruled for exactly 100 years immediately raises questions.   Today, these very earliest of rulers are considered demigods, folk heroes, and sages all rolled into one. The Three August Ones The Three Sovereigns, also sometimes called the Three August Ones, are named in Sima Qians Records of the Grand Historian or Shiji from about 109 BC.   According to Sima, they are the Heavenly Sovereign or Fu Xi, the Earthly Sovereign or Nuwa, and the Tai or Human Sovereign, Shennong.   The Heavenly Sovereign had twelve heads and ruled for 18,000 years.  He also had 12 sons who helped him rule the world; they divided humanity into different tribes, to keep them organized. The Earthly Sovereign, who lived for 18,000 years, had eleven heads and caused the sun and moon to move in their proper orbits. He was the king of fire, and also created several famous Chinese mountains. The Human Sovereign had only seven heads, but he had the longest lifespan of all the Three Sovereigns - 45,000 years.   (In some versions of the story, his whole dynasty lasted that long, rather than just his own life.)  He drove a chariot made of clouds and coughed the first rice out from his mouth. The Five Emperors Again according to Sima Qian, the Five Emperors were the Yellow Emperor, Zhuanxu, Emperor Ku, Emperor Yao, and Shun.   The Yellow Emperor, also known as Huangdi, supposedly ruled for an even 100 years, from 2697 to 2597 BCE.   He is considered the originator of Chinese civilization.   Many scholars believe that Huangdi was actually a deity, but was later transformed into a human ruler in Chinese mythology. The second of the Five Emperors was the Yellow Emperors grandson, Zhuanxu, who ruled for a modest 78 years.   During that time, he changed Chinas matriarchal culture to a patriarchy, created a calendar, and composed the first piece of music, which was called The Answer to the Clouds. Emperor Ku, or the White Emperor, was the great-grandson of the Yellow Emperor.   He ruled from 2436 to 2366, just 70 years.   He liked to travel by dragon-back and invented the first musical instruments. The fourth of the Five Emperors, Emperor Yao, is viewed as the wisest sage-king and a paragon of moral perfection.   He and Shun the Great, the fifth emperor, may have been actual historical figures.   Many modern Chinese historians believe that these two mythological emperors represent folk memories of early, powerful warlords from the era just before the Xia Period. More Mythological Than Historical All of these names, dates, and fabulous facts are obviously more mythological than historical.   Nonetheless, it is fascinating to think that China has some sort of historical memory, if not precise records, from about 2850 BCE - almost five thousand years ago.

Of the most unanswered questions in the human experience, the question of how people successfully navigate a relationship is one of the more prominent. Self-help books, advertising, and talk shows all make use of the topic to promote the sale of their product. However, a deconstruction of romance to examine the components that create this state can help further the understanding of the phenomenon of love. According to Marshall and Rossman (2006), a sense of ‘Should-do-ability‘, ‘Do-ability’ and ‘Want-to-do-ability’ should be examined when approaching a project. Under the ‘Should-do-ability‘ category, a researcher must decide if the research should be done. The research study on romance should be done to further the understanding of this particular human experience. The research can definitely be approached as the concept of romance is highly prevalent in the cultural experience so therefore has a capacity for ‘Do- The question that the research will attempt to answer is best answered from a narrow perspective. The participants in the study will be from a specific parameter of possible relationship types. The main assumption that has been made is that love is a valid state of emotion, but this assumption should be backed by physiological and psychological foundation. In attempting to answer the core question, it will be essential to both observe and interview those who believe they have successfully attained a consistency in the way

Compagnie Generale des Eaux Case Study Example | Topics and Well Written Essays - 1000 words

Compagnie Generale des Eaux - Case Study Example The efforts of Guy Dejouany express the company's commitment in maximizing its financial resources by putting them in different investment opportunities. The leader should also be noted for his effort in minimizing company risk by not putting all its investment in a single industry. In contrast, he tried to distribute risk by putting the company's fund in various industries. Guy Dejouany also broadened intensified the influence of CGE by broadening its reach and market base. By establishing presence in industries where the company has no previous operation, CGE gained more bargaining power through its large size and coverage. However, it should also be noted that the choice of which industry to diversify into is the sole choice of Dejouany according to his personal experiences and relationships instead of generating more formal business analyses. The leader has launched aggressive efforts in order to ward off competition or strengthen the business organization's position against its rivals. In terms of management style, Guy Dejouany can be characterized as a charismatic leader who influenced people through his personality. Though engaged in a wide array of businesses, decision making is highly centralized emanating from a superior who very much involved in the operations of each business unit. During his administration, transactions and relationships have operated on trust while no significant attention is put on the performance of his subordinates. Models of Diversification Employed by Dejouany Keeping in mind that CGE has started as a player in the water utility business, the company's efforts to diversify in health care, transport, telecommunication, and real estate sectors represent a move toward unrelated diversification. With this, it should be noted that Dejouany employed conglomerate diversification or opting to deliver new products to new markets which are the currently not served. In other instances, he also utilized vertical diversification by acquiring business organizations which are in the same value chain. Basing decisions solely in his relationships and personal experiences, Dejouany had undoubtedly entered industries which are highly unrelated. Conglomerate diversification has been used in order to manage the complexity of various businesses under a single portfolio. However, instead of utilizing the company's resources to execute similar processes within business units, CGE maintained the separation between its business entities. In contrast to the typical strategy of acquiring promising small companies, CGE opted to establish new companies which will serve new clients. There has also been no establish relationship between business units and often, subsidiaries are unaware that they are a part of a single organization. Problems in the 1990s The year 1990s sees the near collapse of CGE because of its disastrous financial and overall performance. The problems of the business organization can be traced to its larger business environment and issues inherent to its operation and governance. As discussed above, the decisions within CGE are solely made by Dejouany who build businesses

Extraction of Blue Ice Area in Antarctica

Extraction of Blue Ice Area in Antarctica Chapter 3 METHODOLOGY High resolution satellite data has made it possible to obtain optimistic results in feature extraction processes. High resolution World-View-2 data is used for mapping blue ice areas (BIAs) in Antarctic regions. World-View-2 provides extensively high accuracy, agility, capacity and spectral diversity. First high-resolution 8-band multispectral commercial/business satellite is World-View-2 launched October 2009. Working at an elevation of 770 kilometres, World-View-2 gives 46cm panchromatic resolution and 1.85m multispectral resolution. World-View-2 has a normal revisit time of 1.1 days and it is able of catching up to 1 million square kilometres of 8-band imagery per day. Satellite pictures generally track seasonal annual variations in BIAs coverage over the past 30 year on the East Antarctic plateau region. In late studies, the distribution of BIAs can likewise mulled over from the SAR (synthetic aperture radar) images. In SAR satellite image, blue ice can likewise be outwardly perc eived. The amplitude of blue ice is less than that of snow (white), because the ice surface is smoother than the latter. Yet, distinction is not at all that conspicuous when applying Semi-automatic extraction approach. Blue ice can be distinguished effortlessly in the coherence map got from two SAR pictures in a view of higher coherence of blue ice. It is additionally found that the picture texture data is useful for distinguishing various types of blue ice like rough, smooth and level blue ice. In this study, Atmospheric corrected (QUAC) sharpen calibrated image (World-View-2 data) is used for extracting blue ice areas in Schirmacher Oasis in Antarctic region. Extraction of blue ice area in Antarctica deal with the total area of blue ice areas excluding the other feature (non-target) appearing on or near it. Blue ice areas have some specific qualities that make them of special interest for extraction as they are just 1% of Antarctic region. Many remote sensing approaches have been implemented to monitor and map Antarctic BIAs. 3.1 Methodology Protocol The extraction of blue ice areas is simplified by the Methodology protocol. As the whole image takes time for processing, as Schirmacher Oasis is with an area of 34km ², ranks among the smallestAntarctic oasis and is a typicalpolar desert, so the image is divided in 12 test tiles of different parts of entire World-View-2 image to achieve prior results. Atmospheric correction is done with QUAC (quick atmospheric correction) method to obtain better results. Atmospheric correction to each tile added suitable outputs results to workflow. Calibrated data is also used without applying atmospheric correction to it. Multiband image combination was made from atmospheric corrected data and calibrated data of the study area. Alternating snow and blue ice bands surface patterns are generally found in East Antarctica due to which it is hard task to clearly extract BIAs. For feature extraction processes region of interest (ROI) is considered in which blue ice is target and white ice appearing on or near the blue ice is considered as non-target. Methodology workflow is prepared in order to achieve good and prior results comparing with the previous studies. Extraction of blue ice is not that easy task as dust and white snow appears on it as non-target. Various Semi-automatic extraction methods like TERCAT, Target Detection Wizard, Mapping Methods, Spectral Matching and Object Base Image Analysis (OBIA) are used for extracting blue ice areas in Antarctica. The initial results obtained were good but not better enough to keep them prior. Many trials were carried out for extracting blue ice in Antarctica. Prior results were kept in workflow of methodology to compare them with every trial results. Object based and Pixel based both the classification are used in workflow to get good results. From the High resolution World-View-2 data reference data (digitized data) was prepared for blue ice area and extracted blue ice area was obtained from Semi-automatic extraction methods and OBIA. From the extracted blue ice, blue ice is considered as target and white snow appearing on it as non-target. Comparing reference data and extracted data Bias, % Bias and RMSE values were calculated. After that Average for Bias, % Bias and RMSE values is estimated. BIAS= % BIAS= RMSE= Where, Ref A is Reference area and Ext A is Extracted area n= no. of tiles processed. 3.2 Semi-automatic extraction methods The semi-automatic feature extraction approach intuitively makes endeavours to commonly empowering the insight or data of human perception framework to robustly detect the targeted feature and the computer-aided system to bring fast extraction of targeted feature and exact shape representation. In semiautomatic feature extraction strategy, first target feature is detected by human vision and a couple of estimates in terms of seed points or coaching samples concerning the targeted feature on highlight are typically given. The targeted feature is then portrayed automatically by the PC helped calculations. 3.2.1 TERCAT approach (ENVI 5.1 Exellis Help) [33] The Terrain Categorization (TERCAT) tool creates an output product in which pixels with similar spectral properties are clumped into categories. These categories may be either user-defined, or automatically generated by the classification algorithm. The TERCAT tool provides all of the standard ENVI classification algorithms, plus an additional algorithm called Winner Takes All. This is a voting method that classifies pixels based on the majority compiled from all of the other classification methods that were conducted. In this research, the sub approaches for TERCAT are Maximum Likelihood, Spectral Angle Mapper, Parallelepiped and Winner Takes All. 3.2.2 Target Detection approach (ENVI 5.1 Exellis Help) [33] Target detection algorithms work on the principle of extracting target features based on spectral characteristic of initial coaching spectral signatures of target features, and performing end to the background noise using spectral signatures of non-target features. If the users knows that the image contains at least one target of interest, the wizard can be used to find other targets like it in the same image. The workflow can also be accessed programmatically, so the user can customize options if needed. Target detection tools (ENVI 5.1) were executed to perform supervised image processing tasks into workflows (CEM, ACE, OSP, TCIMF, and MT-TCIMF) to extract blue ice areas (BIAs) as target and white ice as non-target. 3.2.3 Spectral Matching approach (ENVI 5.1 Exellis Help) [33] Spectral matching approaches extract the target features that are described in multispectral imagery based on the target feature’s spectral characteristics. Spectral matching algorithms confirm the spectral similarity or matching between input satellite imagery and reference key points to form an output product within which pixels with similar spectral properties are clumped into target and non-target categories. Spectral Matching (ENVI 5.1) were executed to perform supervised image processing tasks into workflows (MF, SAM, MTMF and SAMBM) to extract blue ice areas (BIAs) as target and white ice as non-target. 3.2.4 Mapping Methods approach (ENVI 5.1 Exellis Help) [33] Selected hyperspectral Mapping Methods describes advanced concepts and procedures for analyzing imaging spectrometer data or hyperspectral images. Spectral Information Divergence (SID) is a spectral classification method that uses a divergence measure to match pixels to reference spectra. The smaller the divergence, the more likely the pixels are similar. Pixels with a measurement greater than the specified maximum divergence threshold are not classified. End member spectra used by SID can come from ASCII files or spectral libraries, or you can extract them directly from an image (as ROI average spectra). Mapping Methods (ENVI 5.1) were executed to perform supervised image processing tasks into workflows [SID SV (0.05), SID SV (0.07), SID SV (0.1), SID MV (0.05) and SID MV (0.09)] to extract blue ice areas (BIAs) as target and white ice as non-target. 3.2.5 Object Based Image Analysis (OBIA) approach (Ecognition Developer Help) [34] Object Based Image Analysis (OBIA), is an advanced method used to segment a pixel based image into map objects that can then be classified as a whole. This kind of analysis is ideal for mapping with high-resolution imagery, where a single feature (such as a tree) might have several different shades of pixels. The example of rule-set for Trial 1, 2, 3 and 4 for extracting blue ice areas in this research is stated below; For Trial 1: 02.063 50 [shape.: 0.8 compact.:0.6] Creating ‘level 1’ Export view to segmentation (no geo) Unclassified with mean nir-1>=50 and mean nir-1 Export view to assign class (no geo) Blue ice with mean nir-1>=50 and mean nir-1 Export view to merging (non geo) For Trial 2: 02.063 60 [shape.: 0.8 compact.:0.6] Creating ‘level 1’ Export view to segmentation (no geo) Unclassified with mean nir-1>=100 and mean nir-1 Export view to assign class (no geo) Blue ice with mean nir-1>=100 and mean nir-1 Export view to merging (non geo) For Trial 3: 02.063 70 [shape.: 0.8 compact.:0.6] Creating ‘level 1’ Export view to segmentation (no geo) Unclassified with mean nir-1>=150 and mean nir-1 Export view to assign class (no geo) Blue ice with mean nir-1>=150 and mean nir-1 Export view to merging (non geo) For Trial 4: 02.063 80 [shape.: 0.8 compact.:0.6] Creating ‘level 1’ Export view to segmentation (no geo) Unclassified with mean nir-1>=200 and mean nir-1 Export view to assign class (no geo) Blue ice with mean nir-1>=200 and mean nir-1 Export view to merging (non geo) The on-top rule-set is employed to extract blue ice areas as well as non-target depending on their mean band values. OBIA is making considerable progress towards spatially explicit information extraction advancement, such as is required for spatial planning as well as for many monitoring programmes. The Semi-automatic extraction strategies and OBIA utilized in this study to extract blue ice areas (BIAs) are supported differently on different underlying principles. To compare these strategies objectively, we kept the input ROIs (regions of interest or coaching samples) constant for all methods for each tile. ROIs are different for different tiles as the area differs. After classifying the image into target spectra, i.e., blue ice areas, using the Semi-automatic extraction methods and OBIA approaches, the 12 semi-automatically extracted tiles (for BIAs) were vectorized to calculate the area of individual tile.

War of 1812 :: essays research papers

List and discuss the events leading up to the War of 1812 and the impact it had on American and Great Britain relations, and the American economy. During Jefferson’s second term in office, fighting between Great Britain and France was posed as a threat to American shipping. Napoleon made the decision to exclude British goods from Europe. As a result, Great Britain decided to blockade Europe and prevent ships from entering or leaving the country. A year later, Britain confiscated American cargoes and seized more than a thousand American ships. France had seized about five hundred American ships as well. America’s anger began to focus mainly on the British, even though France was also involved. This was because of the British policy of impressments. The British decided to capture American sailors, or draft them into the British navy. Also, in 1807, the commander of a British warship insisted on boarding and searching the United States naval frigate Chesapeake. When a United States captain refused to allow him onboard, the British killed three Americans and wounded eighteen. As a result, Jefferson convinced Congress to declare an embargo and ban exporting products to other countries. The Embargo Act of 1807 was eventually lifted in 1809 because it stifled American business. A group of young congressmen, known as the war hawks, were angered by the presence of Native Americans in the Indiana territory. Trobule began when General William Henry Harrison persuaded several Native American chiefs to sign away three million acres of tribal land to the United States government. A confederacy of Native Americans began to organize a fight for their homeland against intruding white settlers. This was lead by Shawnee Chief Tecumseh. Tecumseh’s brother lead the Shawnee in an attack on Harrison, but was defeated. When the war hawks found out that the confederacy was using arms from British Canada, they again called for war. James Madison, another Virginia Republican, declared war against Britain in 1812. He believed that Britain was trying to strangle American trade and weaken the American economy.
