...Constructing Formulas for Mathematical Operations in Excel (Basic Tips and Techniques) Michelle A. Applequist Computer Information Systems (CIS105) Professor Hari Dhungana Strayer University September 1, 2009 Constructing Formulas for Mathematical Operations in Excel Microsoft Excel uses formulas to construct mathematical operations in a worksheet. After data have been entered into the worksheet, you can perform calculations, analyze data, and create charts. An Excel formula (calculations you create) and functions (formulas pre-existing in Excel) calculates the data entered in the worksheet. Formulas calculate numbers in a particular order. “Excel has one of the most comprehensive set of formulas, not only to perform calculations but also to manage data and records. It also has the ability to instantaneously re-calculate the results as the raw data changes” (Khoo, 2006-9, para. 2). To construct a formula after you have entered data, you must click in the cell that you want the results to appear in, and then type the formula. You can construct formulas by using the sum function, and editing numbers in a cell. It is stated that: Sum is an Excel function—a prewritten formula. Sum indicates the type of calculation that will take place (addition). When the sum function is activated, Excel looks above the active cell for a range of cells to sum. If there is no range above the cell, Excel will look to the left for a range of cells to...

In its first month of operation, Maze Company purchased 100 units of inventory for $6, then 200 units for $7, and finally 150 units for $8. At the end of the month, 180 units remained. Compute the amount of phantom profit that would result if the company used FIFO rather than LIFO. The company uses the periodic method. FIFO: $1,410 150 units multiplied by $8 equals $1,200 30 units multiplied by $7 equals $210 $1,200 plus $210 equals $1,410 LIFO: $1,160 100 units multiplied by $6 equals $600 80 units multiplied by $7 equals $560 $600 plus $560 equals to $1,160 Therefore, the phantom profit would be $250 if the company were to use the FIFO rather than LIFO.

...Organizational Design Inescapable? A solid organizational design is what makes the difference; it relies on how strong and solid the organizational structure and design are. According to the Center for Organizational Design, organizational design is defined as a step by step methodology that identifies dysfunctional aspects of workflow, procedures, structures and systems. Realigns them to fit current business realities/goals and then develops plans to implement the new changes. The process focuses on improving both the technical and people side of the business (Allen, 2012). As we live in a world of transition, where everything is changing at the speed of light. The organizational design is an inescapable part of any organization; big or small, is the key element for integrating the people, information, and technology. Having a strong organizational design provides a clear vision, and mission, it empower employees in the decision making of the organization. As a result, the reporting process will be transparent; the information will flow smoothly, and it will provide a definite work process. With a well design structure, everyone will know their responsibility and who they report to (Ingram, n. d.). As our economics and globalization crisis has growth, this has pressure the organizations to re-invent their strategies, structures, roles and functions to be in line with their new goals and objectives. Subsequently, building a team of highly talented professionals, and...

...Organizational Structures After reading this chapter, you should be able to discuss: ■ The differences between line and staff positions as shown on organization charts. ■ How an organization chart is structured showing the lines of authority. ■ The different types of organizational structures presently used by retailers. ■ The beginnings of organization structuring for large department stores and how they have changed to suit today’s companies. ■ Reasons why chain organizations conduct their businesses as centralized op- erations. ■ Why some chains have decentralized some of their functions. ■ Reasons for separating the buying and selling functions. Once the decision has been made to begin a retail venture, it is necessary to plan its organ- izational structure in a way that maximizes efficiency and profitability. All of the duties and responsibilities of those in the company must be identified, and lines of authority must be carefully delineated so that all members of the organization will understand what their job responsibilities are. By doing so, everyone knows who will report to whom, who the deci- sionmakers are, and which advisory personnel is on hand to assist in the decision-making process. No matter how large or small the operation, whether it is a major department store or single-unit boutique, each company must be structured in such a way that best serves its needs and makes the business a success. To clarify their organization’s structure so that all employees...

...Organisation structure Structure relates to a skeletal framework of activities and processes in an organisation and specifies the roles of these in achieving goals and objectives of the organisation. According to (Mullins, 2009), a good structure is highly important due to the fact that decisions on structure are primary strategic decisions which can make or break an organisation. One important aspect of a good structure is the human element. Organisation structure should be designed so as to encourage employees and increase the morale and job satisfaction of organisation members which will result to overall organisation efficiency. (Mullins, 2006) describes nine basic considerations in the design of organisation structure. The fundamental step is to define organisational objectives to enable further analysis and comparisons of other forms of structure. Clarification of objectives A clear definition of objectives is vital to provide a framework for the design of structure of an organisation. Organisation objectives provide fundamental schemes for division of labour and creation of group units and sub units. Clearly stated aims and objectives will assist in decisions on the strategy and structural dimension to employ to achieve organisational objectives. Task and element functions Certain functions must be performed in order to produce a good or service, from the development of the good or service to finance of resources used in the complete processing. These functions...

...Learning Zone Management Structures (Relevant to Paper 2: Business Communication and Organization and Management) Sebastian A. Bombaci, CPA Introduction When a new employee joins a company one of the first things they learn is the company’s management structure. This includes understanding the working relationships with their manager, subordinates and peer group. Management structures appear in every type of organization including government departments, nongovernment organizations (NGOs), charities, and even the local sporting association. Choosing the correct management structure ensures an organization’s continued growth, content employees and profitable returns for the shareholders. Choosing the wrong structure creates tensions between employees and managers, allows inefficient work practices to flourish and reduces company profitability. In the worst case an incorrect management structure can lead to company closure. Unfortunately, many managers take it for granted that their organization’s management structure is correct, static and never requires changing. However, such assumptions are naïve and as the pace of change increases, there is a need to continually assess the suitability of a company’s management structure. A very topical example of an inappropriate management structure is that of the American automobile manufacturers. A combination of out-dated management structures, inefficient business processes, poor work-place relationships...

...this coordination, the organization must have a structure to it. Organizational structure is essential in specifying reporting relationships, delineating formal communication channels and in linking all activities together toward organizational goal achievement. There are two primary structure types; organic and mechanistic. There are four main elements to organizational structure; centralization, formalization, hierarchy, and departmentalization. These elements often coexist in organizational structures and their configuration will determine whether an organization is organic or mechanistic. Organic organizations are less formal and more flexible than traditional organizations and are characterized by such things as flexibility, informality, and knowledge based authority. An organic structure is laid out like a network and emphasizes horizontal specialization, personal coordination, and extensive communication. Organic organizations are generally flat and decentralized, with little reliance on formal authority, which enables faster decision making. Mechanistic structures are primarily hierarchical, with an emphasis on specialization, and vertical communication. Mechanistic structures also place an emphasis on control by relying on rules, policies, and procedures in conducting operations. Mechanistic structures are highly formalized and centralized and as a result are more rigid and resistant to change. Determining which structure is best is dependent on the stage of development...

...BSA 310 May 15, 2011 Rich Harrell Critical Information Systems An Information System is an organizations framework for efficiency, productivity, and functionality. It “is a collection of hardware, software, data, people and procedures that are designed to generate and disseminate information and data that supports the activities of an organization” (International Graduate, 2011). Kudler Fine Foods is an organization specializing in providing domestic and imported sustenance to consumers. This paper clarifies an information system critical to their business process and examines how this system has an effect on the organization’s intricate structure. Information Systems Information systems used by organizations often follow a “traditional hierarchical structure” (Turban & Volonino, 2010. p.42). The structure commonly consists of seven functional types (1) Personal and Productivity Systems, (2) Transaction Processing Systems, (3) Functional and Management Information Systems, (4) Enterprise Systems, (5) Inter-organizational Systems, (6) Global Systems, and (7) Special Systems. Each category plays an essential role in the overall function of an organization when utilized. The development of an application program is used to execute or support a specific organization task or business process through the use of that information system. Although system types and applications can be independent of each other, most systems and programs are often reliant on each...

...possible. Activities, for example such as task allocation, coordination, and supervision directed toward the attainment of organizational aims are the elements of organizational structure. In conjunction with structure is organizational design, the plan. According to Hearst Communications, Inc. (2013), “When a company's leaders develop plans for how their company should function or would perform better, they undertake the business of organizational design. Good design takes inventory of all the tasks, functions and goals of a business, and then develops groupings and orderings of job positions; departments and individuals to best and most efficiently achieve those ends. Usually, designs are expressed through an organizational chart, which helps players throughout an organization understand functions and power relationships” As a business’s environment changes it is vital to identify, reassess, and possibly change one’s organizational structure and design. Knowing how to respond to the environment aids the company as economic, legal, political, and social circumstances change. Virgin America Airlines is expanding into China, and management realizes recommended changes in strategy may affect its current organizational structure and design. This discourse summarizes its existing organizational structure and describes the existing organizational design with specific discussion of how work is divided among people and departments as well as how Virgin America Airlines uses its resources...

...wanted to reorganize their organization structure to help them improve efficiency, respond to environmental changes and increase communication between apartments. Environment: Aquarius is a traditional organization and has a hierarchy system that makes the company inflexible to change. They need to change this in order to keep their organization alive from other advertising firms (competitors) and current customers changing advertisement firms. Size: Aquarius is a middle-sized firm that offers two services to their clients. They currently have an organization structure that was a hierarchy structure which included upper management, managers and other operational staff. Culture: Aquarius wanted to improve on their communication of their departments so they can sustain and increase their excellence of attracting and maintaining their clients. Technology: Aquarius had many different communication methods and tools to deal with their clients. They contacted clients through email, telephone and made formal meetings with their clients. They also had the technology and software to create ads for televisions, newspapers, the radio, the internet and billboards 2. I think Aquarius should move towards more of a horizontal structure rather than a vertical or traditional (hierarchy) structure. I think they need to integrate their Accounts, Operations and Marketing teams to have more horizontal communication between each other. The horizontal structure will allow more of decentralized decision...
