Traditional Information Systems
Transaction processing system (TPS)
Transaction processing was one of the first business processes to be computerized, thereby producing a system known as the TPS. The TPS serves as a foundation for the other information systems that may be present in an organisation (discussed later.) TPSs perform routine operations or transactions; e.g. customer orders, purchase orders, receipts, etc. The amount of support for decision making that TPSs directly provide managers and workers is low. These systems require a large amount of input data and produce a large amount of output without requiring sophisticated or complex processing. The TPS may be based on the functional structure of the organisation and may comprise, for example, order entry, inventory control, payroll, accounts payable, accounts receivable, general ledger, etc. The input data are the basic business transactions mentioned earlier (e.g. customer orders, purchase orders, receipts, time cards, invoices, and payroll checks.
The two basic types of TPSs based on the processing type are batch processing system whereby business transactions are kept over a period of time and prepared for processing as a single unit or batch. The essential characteristic of a batch processing system is that there is some time lag between the moment the transaction occurs and the time it is processed and the organisation’s record updated.
Available computer technology now also allows the transaction to be processed on-line in real time (OLTP, on-line transaction processing). Each transaction is processed immediately, and the system immediately updates the records affected by that single transaction.
The principal purpose of TSSs is to answer routine questions and to track the flow of transactions through the organisation.
TSSs are routinely…...

...Costing (ABC) over other costing systems. Also identify at least one company that uses ABC and describe how it benefits the company. Introduction This paper has been formulated in order to determine the basic nature of Activity Based Costing, its advantages and disadvantages. These points are further elucidated by a case study of a Taiwanese hot spring country inn’s implementation of the ABC system. What is Activity Based Costing The Activity-Based Costing theory started in 1987 by Robert S. Kaplan and W. Bruns as a better alternative to the traditional costing method. It has activities as the fundamental cost objects and assumes that activities cause costs and that cost objects create demands for the activities. A traditional costing system uses a single, volume based cost driver. In most cases the traditional system assigned the overhead cost to products on the basis of their usage of direct labor. For this reason traditional cost systems often yields inaccurate product costs and becomes inadequate in terms of calculating true cost to produce specific products for specific customers. ABC system was developed to overcome the shortcomings of the traditional method by using many cost drivers to allocate a indirect costs instead of just using one cost driver such as machine hours. ABC system uses a different approach and allows improvement on the control of overheads by cost/cause relationships that are activity and cost. This flexible system is able to relate costs to......

...accounting section, it helps make it easy and interesting to the individual. Indeed computerized accounting has a great impart in the accounting system. But to say that two or three weeks of training in computer program in accounting is the best way in accounting system, for that I disagree with it. Yes the computerized accounting has help in many ways but it does not supersede the manual or the tradition way of accounting. The manual or traditional way of accounting is the process of recording transaction on the paper or in a document in a raw fact. The combination of the two which is the manual and computerized accounting system is the best way of accounting but specializing in the computerized system is not the best way. There are functions that that can be concerned as in effective way of accounting. * COST One of the bigger advantages in the manual accounting is the cost saving compare to computerized accounting. Computerized accounting software is expensive according to accounting.

Time Driven Abc

...Time Driven ABC costing is more superior to the traditional method in many different ways. Overall there are many negatives to the traditional system including its higher cost, low accuracy and is an extremely complicated system. The time driven ABC costing has many benefits including its lower cost, ease of implementation, higher accuracy and the larger scope of its models. Traditional ABC costing has been used for a very long time but with the introduction of modern computers it allows for Time driven to be a much more effective cost system. The traditional cost system is quite expensive and time consuming because it requires a lot of people to maintain and gather the necessary information to try to create an accurate cost system. Due to the time consuming nature of the system it is infrequently updated and leads to inaccurate cost estimates. Also when information was gathered from employees many employees did not consider the time spent in a nonproductive fashion. So many cost drivers were created under the notion that employees were working at full capacity. Overall the traditional cost system does not even come close to matching the accuracy of Time Driven ABC costing. Time Driven ABC costing is superior to traditional costing mostly because of its increased accuracy. It is much easier to implement because the only factors that it requires is the cost rate of supplying resource capacity and the consumption of the resource capacity by the products or services.

...what is traditional financial system? Traditional financial systems mean financial systems are used in companies before. Risks of traditional financial systems 1. Delays – The CEO needs the latest consolidated financials. The best finance can do is offer reports that are already weeks old – or reports based on today’s numbers that will be available next week. 2. Security Risks – Security is compromised when someone accidentally emails confidential reports to a vendor instead of the board of directors. 3. Errors – To create reports, the finance staff has to download data from one or more financial systems and aggregate, manipulate, and format the data in a spreadsheet – providing ample opportunity for errors and reducing finance productivity. 4. Increased Software Costs – The controller gets a $100,000 invoice for add-on data warehousing and reporting software – plus an HR request for $100,000/year for IT staff to manage them. Traditional Financial Systems vs. the Cloud The business world today is highly competitive, collaborative, and distributed. In order to gain a sustainable advantage, every stakeholder must make intelligent decisions based on real-time information.

Activity Based Costing

...using the same traditional costing systems, Cooper and Kaplan (1991).The absorption costing paved way due to the lack of visibility for indirect costs so the ABC has been adopted by many organizations rapidly. According to Krajnc et al. (2011), the main difference of ABC to absorption costing lies on how they treat indirect production costs (overheads) and sales. The fundamental goal of ABC is to identify as much as possible direct relationships between products and resources consumed through activities conducted from production to disposal. The ABC system is based on the assumption that the support activities such as activities and sales, the cost of which traditional systems characterized as overheads, offer opportunities for the implementation of activities, and thus are not just for sharing costs. In an absorption costing when the volume of overheads is larger, the likelihood of distortions in reported costs is also greater. In general, overheads that exceed 15 percent of the total cost can cause inaccuracies, Turney (1996). Many companies had major problems by these inaccuracies and so they started using ABC. The traditional approach to cost allocation consists of three steps: Concentration of costs in the productive and non - productive parts. Allocation of the cost of non-productive segments in section production. Distribution of the resulting costs of production in the department products, services and customers. The costs resulting from the traditional......

Activity Based Costing: Abc/Abm Implementation

...Abstract There are two main cost allocation systems exist. Traditional cost allocation system allocates costs based on volume of production or proportionally to sales revenue. Such approach usually underestimates costs for low-volume products or services and over-estimates costs of high-volume products or services. To avoid such situations Activity Based Costing (ABC) system was developed. ABC system main principle is to identify main activities of the company, group costs of these activities, identify how these activities can be measured and assign costs to products or services though these measures. ABC system helps managers to allocate costs more accurate to final products or services. However, ABC system has some limitations. For ABC implementation company needs a lot of resources (trained personnel, additional IT and information resources). Some of the potential users are often change their mind of ABC implementation after expenses for system implementation and maintenance are calculated. Other disadvantage is the complexity of the system. Implementation of ABC system could be highly complex if company has a lot of products and need to allocate its costs to a number of activities. Support and maintenance of such systems is complicated and time consuming process. ABC system gathers and provides valuable information for decision making. This approach is called Activity Based Management and could be used to improve efficiency of the company. Notwithstanding its......

Pto Polcies

...with two different PTO policies is a difficult task as ultimately; there must be one newly created policy for all employees to follow. In addition, HR will need to further research each company for information to determine the newly formed paid time off policy once the companies have merged. Length of Employment * Usually it is important to know how long an employee has been with the company. Paid time off is accumulated over time and the length of an employee at a company can really alter their paid time off. This information is important to make sure paid time off is given fairly but also to protect the company from people who join the company just to receive paid time off. Attendance * Employees work different hours throughout the day, week, month and year. Some employees are required to work 40 hours a week; some are required to work more or less. This information is needed to help define the paid time off policy and help narrow down the qualifications Employee type * In most companies there are full time employees whom are entitled to all benefits and incentives. There are also outsourced and contractor employees within a company. The different types of employees do not share the same benefits and this is why this information is important to HR.

Emergence of Activity Based Costing

...Emergence of Activity Based Costing The Traditional cost accounting methods were designed around 1870-1920 and in those days industry was labour intensive and there were no machinery. The product variety was small and the overhead costs in companies were generally low compared to today. During the 1980s, it became clear the conventional techniques for recovering overheads were increasingly providing the management with cost information that was inaccurate and misleading. As a result new techniques for overhead recovery were needed. In order to produce a more accurate costing system, cooper and Kaplan in 1987 developed a more refined approach for assigning overhead to products and computing product costs and called this approach Activity Based Costing (ABC). It was first clearly defined as a chapter in their book Accounting and Management: A field study perspective. (Kaplan, Roberts 1987). While mainly used for private businesses, ABC has recently been used in public forums, such as those that measure government efficiency Features of the ABC and Traditional costing system Activity Based Costing can be defined as an accounting methodology that assigns costs to activities based on their use of resources, rather than products or services. This enables resources and other associated costs to be more accurately attributed to the products and the services which they use. It doesn’t change or eliminate any costs; it provides detailed information about how costs are......
