Evaluation Of A Sdlc, System Development Life Cycle

1. According to Rosenblatt (2014), a SDLC, system development life cycle, describes how to plan and manage systems development and the activities and functions of systems developers will perform. The waterfall model is divided in five steps and the result of each one is a deliverable to the next step. The first step is called Systems Planning and starts when the IT department does a systems request. This phase is responsible for doing a preliminary investigation to know the situation and evaluate the necessity of this new system. The principal part of this investigation is called feasibility study and it is responsible for showing anticipated reviews of the costs, benefits and course of action. The second step is called Systems Analysis and it purpose is to build a document with the system requirements, showing details as management and user requirements, benefits, development strategies and costs. The third step is the System Design, happens when is necessary to create a physical model and identify the processes (inputs and outputs), satisfying the requirements. Its deliverable is the systems design specification. The fourth step is the System Implementation and during this phase, the new system is constructed. The purpose of this step is to deliver an information system, functio ning and documented. The last step is the Systems Support and Security and during this phase, the IT department is responsible for maintaining, enhancing and protecting the new system.

Organisational Culture and Organisational Structure

Question: Discuss about theOrganisational Culture and Organisational Structure. Answer: Introduction Organisational culture is a system consists of explicit and implicit instructional techniques and policies, designed to outline the various work functions and responsibilities. Organisational culture signifies the combined values, beliefs and the ideologies of the members of an organisation and is a collective product of several factors such as, product, history, values, market strategies, employees, management strategies, national cultures, also the beliefs, norms, systems of the particular organisation. In this essay, the famous Australian supermarket chain Woolworths Limited is taken to analyse the organisational culture, the organisational structure, and the application within the organisation. (Methner, Hamann and Nilsson 2015) The major factors determining the organisational culture are symbols, rituals, story, and control and power link. The symbols in an organisational culture determine the human behaviour within the company. Symbols trigger to remind people the rules and regulations, beliefs and policies within the culture. They sometimes act as a simple way to keep the employees aligned. Those can also be used as the indication status with the organisational culture, containing office decor, clothing etc. The status symbols are indicators to use the proper behaviour with others in the hierarchy within the organisation (Neuhaus et al. 2014). The symbols determine the appropriate attitude towards other employees according to their status and position in the company. There might be several symbols around a company, starting from welcoming cultural members around the globe to the pictures of different products on the walls. Rituals are an integral element in an organisational culture. It generally contribu tes to the operating process of the company. The rituals are the procedure or the set of proceedings, which are repeated in a specific situation with a particular meaning, but it also had a symbolic part to embody the values of the company. The stories within an organisation are the sequence of true events, though often exaggerated when told to the new employees. The most common narratives in an organisation are the stories of the founders or the chief leaders, the challenges they have faced and their way to deal with those hurdles etc. In a way, these stories are mainly used to encourage the employees; also, these are the medium of carrying the legacy in a company. The organisational culture also influences the management to have a control over its employees. If the management has a definite form of guidance, well-described jobs, and authoritative decision taking procedures, it is considered to have a formal process of control over its employees, whereas, the collective decision-ma king process is considered a cultural way of control. This also depends on the power link within the organisation, which describes the hierarchy (Persson 2013). With respect to the in-house environment in Woolworths, there are few major points in implementing the organisational culture. Woolworths has always been an example of excellent leadership and creating a sustainable environment by closely working with their suppliers. They have improved their amount of profit and overall organisational culture through it as well. The workspace is considered as a driver of the performance of the employees. The culture creates a sense of continuity, order and commitment in the employees, so that they can work with dedication. Having a perfectly implemented organisational culture establishes a sense of positivity within the employees, so that they also have the encouragement for work (Persson 2013). Woolworths always aims to improve their organisational culture by involving themselves in the community and working together towards the constant growth of the company. This always helps to improve the personality of an employee, where he has the correct amb ience to work (Shields et al. 2015). There are few challenges in implementing the organisational culture in a company, because there are always commitment issue among the employees. Different teams might have issues against each other, like the sales and the accounts team can turn against each other; logistics and manufacturing team might have conflicts between them on the basis of creating new products. This can always affect the productivity of the company. However, several surveys show that, to increase the employee loyalty, the leadership needs to be effective and strong, and the personal issues should be kept aside when it comes to company growth. Organisational Structure Organisational structure can be an ambiguous term to determine, but to state it minimally, it can be said that it defines a specific hierarchy in a company of every shape and size. However, the organisational strategy is the plan to execute the use of the primary resources in the company. The organisational structure plays a major role to achieve the general strategy in a company, where the organisational culture plays a very important role to accomplish the company policies as well. There are several issues in a company for the execution of the organisational structure; one of the major issues is the function. Several companies use vertical or horizontal structure to grow rapidly. Mostly small companies use the horizontal structure, where the manager can directly contact the president. It also defines the distribution of authority within the organisation. The company needs to channelize their communication flow through the team leaders, so that the employees do not get confused about the reporting. In fact, the structure helps the employers define the skills of their employees as well. The linear structure helps the superintendents to evaluate the progress of the work of their employees (Sorensen and Stanton 2013). If the work-progresses are sorted within the company, it is helpful in achieving the targets as well. It can also be said, that the structure promotes teamwork, where all the employees work towards a common goal. The structure also allows the change i n the company policy. In other words, the structure is helpful to regulate the company policies. The six key element of organisational structure are Work specialization, Departmentalisation, Chain of command, Span of control, Centralisation and decentralisation, and Formalisation. The company structure entirely depends on these key elements and they determine the flow of the strategies as well. (Hubbard, Rice and Galvin 2014) Woolworths is a popular company, grown rapidly within few years, and has around 400 stores all over Australia. The company is known to be polite and respectful towards their employees and considers them the biggest assets in the organisation. Woolworths always believe in assigning right job to right people. They always work together to make their employees better and more committed retailers. Woolworths has classified their organisation into different sectors to departmentalize their tasks (Lozano 2013). In the organisation, the chain of command is a continuous flow of control, where an employee is answerable to his direct superintendent. The sales managers of both the retail and the wholesale accounts are answerable to the director of sales. The functional and the divisional structure of Woolworths is divided in a designed way. The company follows the divisional structure, where the general manager of any retail outlet is always responsible for their performances in every sector. There are several challenges in the implementation of the organisational structure like the communication problem, delegation of responsibility in different sectors etc. Apart from that, the implementation can cost a fortune for the company. Nevertheless, there are few proposed changes can be done, like developing the right job description for the employee, so that there will not be any confusion or difficulty in assigning any task (Bailey 2016). If there are huge gaps between the job requirement and the employee profile, the growth of the company can be hampered. The company can plan an organisational chart after a certain interval to avoid misunderstanding. Reference List Bailey, M., 2016.

Blood Turns The Wheels Of Our Lives free essay sample

Essay, Research Paper Blood Turns the Wheels of our Lifes Guns have played an of import function in the defining of America, from the revolution in 1776 to the rampant offense of modern twenty-four hours. They have been used to contend two universe wars and halt dictatorship all across the Earth. The ownership and use of guns in America is good because it advocates self defence, supports the conflict against dictatorship, and encourages psychological development in society. Crime in America does non fluctuate in conformity to guns and conceptual ego defence demands to be more fecund and recognized. Crime has ever taken topographic point and will ever take topographic point, and felons will ever hold guns ; this world allows people no pick except to understand and accept the function of guns. The most important gun control Torahs of the 20th century have had small affect on offense and decease rates. The National Firearms Act of 1939 and the Gun Control Act of 1968 had perfectly no evident affect on the invariably fluctuating decease rates ( GunTruths. com ) . In fact the slaying rate rose significantly twelve old ages following the Gun Control Act of 1968 ( GunTruths.com ) . Since 1900 the figure of pieces in the state has invariably risen. However, the figure of violent offenses caused by pieces has been in flux, without any respect to gun ownership. At the terminal of the 20th century the greatest figure of pieces are owned, yet the slaying rate is at a 30 twelvemonth low ( GunTruths.com ) . In a survey by the University of Chicago sing the disincentive of offense because of pistols, it was shown that slaying was reduced by 8.5 per centum, colzas by 5 per centum and aggravated assaults by 7 per centum ( GunTruths.com ) . Guns are an imperative portion of endurance and protection, without them we will be capable to fear and submission deducing from offense and the menace of force. Tyranny has been a menace in America from it # 8217 ; s get downing old ages as a new state to it # 8217 ; s substantiated place as a universe power. When Great Britain ruled over what is now the United States, subjugation and revenue enhancement without representation were common parts of people # 8217 ; s lives. The allowance of guns within colonial society enabled civilians to contend against Britain and to liberate themselves from civil development. They decided that their hereafter was non one of dictatorship and subjugation, but one of freedom and autonomy. Firearms were the most used arm in the American revolution and without the usage of pieces the state in which we reside would non be today ( Zinn, p.76 ) . Throughout the last two centuries guns have been used to protect freedom and people # 8217 ; s manner of life. When the south succeeded from the brotherhood it was guns which were used to contend for their manner of life. When inkinesss were oppressed in the mid 20th century they turned to transporting guns for protection. The Black Panthers carried pieces for their ain protection in the mid 20th century. Today all around the universe the American authorities conflicts against undemocratic and oppressive forces utilizing pieces. The usage of guns against subjugation is a really of import construct for Americans to understand for it could be extremely necessary someday. Americans could be faced with a determination to take up weaponries someday and dice on their pess instead than populate on their articulatio genuss. Fatal gun accidents take topographic point all around our state. Peoples have become sympathetic and weak to this state of affairs, particularly in respects to the deceases of immature kids. There were one-thousand-five 100 inadvertent deceases due to pieces in 1997 ( FBI.gov ) . Merely two-hundred and 20 of those deceases were kids, which is merely approximately 15 per centum of the entire sum ( FBI.gov ) . In many instances these accidents occur because an person has acted irresponsibly with a piece, in decision pickings their ain life. In other instances person will move irresponsibly and take person else # 8217 ; s life. In the first state of affairs the individual deserves to decease for moving with a deficiency of intelligence. Society is better off without these potentially unsafe people. Their station in life could be one taking to the decease or hurts of persons around them. In the 2nd state of affairs the individual # 8217 ; s life is given in order to learn the attacker and society the dangers of intellectually inferior people. These people who by chance shoot another individual should be regarded as inept and exemplified as a failure in society. The decease of their victim is a sufferer # 8217 ; s decease, one that is looked upon as something that benefited society. The accidents that could potentially take topographic point due to pieces are calamities that further the psychological promotion of society. Firearms have affected America in many positive ways in respects to the combat of oppressive forces, supporting one # 8217 ; s self and germinating society psychologically. Gun will ever be an component in our lives ; if they are outlawed, so the lone people who will have guns will be the felons. Firearms have been an optimum tool in America, they guarantee our freedom and they will play a big function in any major struggle in old ages to come. Guns allow us to free ourselves of potentially negative parts of our society, such as irresponsible persons. Everyone can profit from the allowance of guns in our society, for if we don # 8217 ; t protect ourselves and make our ain freedom, who # 8217 ; s traveling to make it for us?

American Advantages Essays (706 words) - , Term Papers

American Advantages American Advantages Why the British Should Not Have Defeated the Americans in the Revolution In the second half of the eighteenth century, the British were faced with rebelling colonies. Finally realizing that they had to fight to keep their colonial possessions, the British sent troops to America. Once the battles began in America, the British were not impressed with the colonial military, but the weak militias soon proved to be effective. With foreign aid from France, American devotion, and the lack of British vigor, the Americans soon discovered the open doors of independence. In my opinion, the American advantages and the British disadvantages proved to be the downfall of the English in the American Revolution. Even though the British army was larger, the American army proved to have talented fighters. The Continental Army and the state militias were essentially the two military organizations of the Americans. Throughout the war, the Americans employed only 231,771 men, which meant that the American forces rarely numbered over 20,000. Compared to the British, the American army was small, but their military tactics and skills were excellent. From a distance of 200 yards, an American rifleman could easily kill a British soldier. Many men observed that the British plainly fired in the general direction of the Americans, while the Americans aimed for the heads of the British. Also, the Americans had many more competent and talented leaders. George Washington and Benedict Arnold were two of the most brilliant American leaders. During this time period, the British firing techniques were not effective. The commanders lined up their troops in lines, one line in front of the other. Then, the British soldiers fired, knelt down, and then reloaded their weapons. While the British were standing in the open, the Americans used guerrilla tactics and fired upon the British while using the trees as protection. When the British retreated, they marched in a single file line. Brilliantly, the Americans ran ahead of the retreating British and picked them off with their rifles. Almost defenseless to this American technique, the British lost many soldiers. The British hired German mercenaries, Hessians, which proved to be an unreliable source of troops. Overall, the British did not win the war because the Americans knew how to fight effectively with their limited troops. With some foreign aid from France, the Americans found that they held an advantage in supplies. At one point in time, the Americans were using 90% provided French gunpowder. Also, the French provided a strong navy which protected the American coastline. France fought against the British because they wanted revenge, and they also wanted to reclaim some territory that they had lost in the Seven Years War. Fortunately, the Americans were supplied with French money, armies, and supplies, so I would have predicted an American win. One of the greater advantages that the Americans held was that the British underestimated them. Even before the war began, an anonymous British officer bragged that the Americans could be beaten by an experienced sheep herder. This remark clearly shows that the British thought that the Americans were weak. In fact, the confident British did not push to accelerate the war in 1775 and 1776. The Americans won the war because Lord Howe, a British leader, and his troops did not fight to destroy, but rather fought to control. If Howe would have fought to destroy, the Americans could not have fought back. England did not win the war because they were unprepared and over confident. In my mind, the Americans cherished a moral advantage that came from their belief in seeking freedom. Even in defeat, the Americans optimistically looked forward to the next battle and planned their strategy. Many Americans held the idea that they were going to fight until they won independence, or they would die fighting. This tenacious confidence proved to be the most effective fighting technique of the Americans. On the other hand, the British held the attitude that they were only keeping a bunch of weak farmers under control. From the British point of view, America acted as a giant trading post used to benefit England. The English stupidity combined with other disadvantages denied them even a chance of winning the war.
