...Access Control, Time Log, and Billing Application Executive Summary The need to maximize the economic performance in business organizations remains a key objective for many companies. Since firms lack an effective way to monitor the activities of the workforce, most of the business organizations needs to acquire access control systems, time log, and the billing application. The system assists companies in determining the productivity of the enterprise. Development of well-functioning application that would suit the needs of the ultimate users is often a challenge to the IT engineers. The main issue with the incomplete application is caused by inadequate communication between the developer and the program developers. There have been many research reports that suggest the appropriate procedures in the development of programs to avoid development of uncompetitive programs. Another issue with the development of faulty programs includes failures of the sponsors to provide the adequate requirements for the application. A research on this matter indicates that many firms continue experiencing reduced quality systems. Some organizations spend enormous amount of finances in hope to acquire adequate systems that would satisfy their intended needs. It is unfortunate that some of the developed systems end failing to deliver as expected by the sponsors. Such issues emerge from inadequate communication between the users and developers. In some cases, they might manifest after implementation...

...Gun Control, An Idea That’s Time Has Come As a Criminal Justice student I lean toward the gun control side of the current debate. In his Federalist Papers James Madison said, “Americans have the right and advantage of being armed – unlike the citizens of other countries whose governments are afraid to trust the people with arms” (Raymond). Madison may be right about our citizens having more rights than those in other countries, but our government places too much trust in the American people. If you take away privately owned guns, it does not solve anything because doing so would consequentially create a communist or police state. Instead of taking away the guns, a better solution is to control who buys guns and for what purpose they should be used. Opponents of gun control may say that a seven-day waiting period before being able to buy a gun does nothing to help fight or prevent crime or to save lives, it is needed to keep more people from dying, to keep people from being robbed, and to keep guns out of the hands of known criminals. There are over 283 million licensed guns in the U.S. (Herbert 1), and that does not include unregistered and illegal weapons that people own, sell to and buy from unlicensed or criminal sources. The Second Amendment of the U.S. Constitution grants Americans the right to “bear arms,” but when they kill innocent people or even themselves, should all Americans have that right? More than 50% of U.S. homes own one or more guns (White 1). The question...

...INTERNAL CONTROLS JANINE LEWIS XACC/280 DECEMBER 8, 2013 JOSE RODRIGUEZ INTERNAL CONTROLS Internal controls are methods that companies put in place to protect themselves from errors, internal fraud or corruption. The methods consist of review, checks and balances, and procedures that make sure a company’s business is being conducted orderly and efficiently. They also ensure that the policies and procedures that are put in place are being adhered to. Internal controls are necessary for many reasons; however there are two primary goals. One is to protect the company and prevent theft, errors, fraud, and unauthorized use of resources and assets. The other is to detect and quickly reconcile any errors that may occur, and ensure that accounting and financial data is accurate and reliable. The Sarbanes-Oxley Act of 2002 was put in place as a result of the many corporate scandals that has happened. Under this act, companies are required to have an internal control system in place. If a random or scheduled audit discovers a company does not, they are subject to fines and possible jail time. SOX have affected internal controls in several different ways. In one way, it keeps a continuous watch over a company’s internal control system to ensure that the current methods continue to be reliable and effective. For example, over time, a company may change its computer system, its reporting method, or other ways pertaining to their finances...

...Project : Logistics Control Tower Objective: To design a Logistics Control Tower Solution for E-Commerce Companies Write-up: A control tower is a single command centre for visibility, decision-making, and action, based on real-time data. It’s a powerful cloud service providing a comprehensive unified prospective of your business; top-down to bottom-up. Cross functional team can now rely on a single product to plan, monitor and respond to all business challenges (in this case all issues occur in logistics) quickly, collaboratively enabling you to measure the impact of changes, study response scenario, recalibrate strategies and envision what’s coming down the road, allowing you to see and know it all at the same time. With the help of control tower, Company (and supply chain) will come to be recognized not as a collection of separate functions but as a system in which the flows of information, materials, manpower, capital equipment, and money setup forces that determine the basic tendencies towards growth, fluctuation, and decline. A Supply Chain Control Tower system includes a dedicated team of people responsible for monitoring the alerts of the tower and for taking action when the tower predicts an incident may happen or if an incident already happened. This designated team is delegated the authority to make real time decisions based on the alerts and recommendations reported by the Control Tower. A properly structured Control Tower must be “armed with both the ability to determine...

...Chapter 18 Production Planning and Control In any manufacturing enterprise production is the driving force to which most other functions react. This is particularly true with inventories; they exist because of the needs of production. In this chapter the relationship of production planning and control to work-in-process inventories is stressed. Objectives of Production Planning Control The ultimate objective of production planning and control, like that of all other manufacturing controls, is to contribute to the profits of the enterprise. As with inventory management and control, this is accomplished by keeping the customers satisfied through the meeting of delivery schedules. Specific objectives of production planning and control are to establish routes and schedules for work that will ensure the optimum utilization of materials, workers, and machines and to provide the means for ensuring the operation of the plant in accordance with these plans. Production Planning and Control Functions All of the four basic phases of control of manufacture are easily identified in production planning and control. The plan for the processing of materials through the plant is established by the functions of process planning, loading, and scheduling. The function of dispatching puts the plan into effect; that is, operations are started in accordance with the plant. Actual performance is then compared to the planned performance, and, when required, corrective action is taken. In some instances...

...this document and save it to your student account. Lesson: Control structures – Notes From the website: academy.oracle.com, go through the section on “Understand IF and WHILE structures” and take notes using the questions below. A. Understand IF and WHILE structures What is a control structure? Control structures are pre-defined statements that determine the order in which programming instructions are executed. List the control structures available in Alice: • Do in order • Count • While • For each in • If • Do together • Each in together What is a conditional execution control structure? Allow you to control execution based on a condition, or a decision being made. What are the two parts to an IF control structure? If and Else. What are two facts about a WHILE control structure? • Acts like a gatekeeper to an event. • Must be true to allow the programming instructions within the loop to execute. What happens when the condition of a WHILE is false? The control structure will be skipped and execution will continue with the next programming statement following the WHILE control structure B. When to use the control structures In this chapter, and Chapter 5, we will use these control structures: • Do in order – use this when you want the actions to happen sequentially (one at a time, in order) • Do together – use this when you want the...

...Describe the kind and strategies of control applied by your manager to control the employees' job. Be specific by showing examples. In case you are not working, please, refer to your last job. Controls can be classified according to the time at which the control is applied to the activity-before, during or after. My last job was in OCASA, my manager was Lisebel Sardinas she is a good manager, she gave me the responsibility on my jobs and tasks day by day, the time elements in controls that I considered she used inside the company is the Feedback controls; the major reason is because she evaluate an activity after it is performed, as example every Friday after 12 pm I did a report, and she evaluated how much I advanced in my job and how this affected directly or indirectly the control on OCASA, what I did in my job was send and copy each of the invoice of the customers Monday to Wednesday, and Wednesday to Friday receive the checks or confirmation of deposits of each accounts receivables, Monday early she used the feedback control to develop a new strategy if the employee was inefficient on the job. Is important for controls in my opinion have a monitor of activities while they are carried out and I think she used this control concurrent on the weekdays to help to us, do a better job, because she observed performance and how the employee has been progressive if she noted that something is in bad communication immediately she took the time to correct the action and show to the...
