ACS 1803 STUDY QUESTIONS 2 For final 1803 exam in April, 2009 (The following questions are intended to help guide your studying. Be sure to emphasize understanding of how all the ideas fit together - until you feel that you can explain these ideas to someone else. The final exam will be based almost entirely on material addressed in these questions below and on the bolded questions from the Mid-term study questions.) Firstly study all questions in bold on the study question sheet for the mid-term in March, 2009 modified for the final exam (to be found on the 1803 website). Then, study ALL questions on this sheet. 1. Explain the fixed assets system and the payroll system. ? 2. What are main features of Point of Sale systems? ? 2b. What is the difference between online processing and batch processing? (LO6 slide 3) Online processing can be processed individually in real-time, while batch processing is grouped and processed together at a later time. 2c. How does a management information system differ from a transaction processing system? TPS's are a special class of information system designed to process business events and transactions. MIS's are 1. a field of study that encompasses the development , use, management, and study of computer-based information systems in organizations. 2. An information system designed to support the management of organizational functions at the managerial level of the organization. The difference between the two is that a TPS is used at the operational level of management, while and MIS is used at a managerial level of management. 3. What is the purpose of budgeting systems? Why are spreadsheets a good base for such systems? Plan revenues and expenses line-by-line, can summarize in various ways, can compare this year's budget to last year's, can compare actual expenses vs. budgeted(get actuals from General ledger System).\ Spreadsheet-type systems are useful for budgeting, because of formulas and they can use last year's budget as a base for next year and maybe 5 years. 4. What is the contribution of cash management systems? What management level do they support? Outline one useful report. Ensure that business has sufficient cash to meet its needs for day-to-day operations and for acquisition of long-term assets. They support an operational level of management. One useful report is the cash flow report, which can forecast cash flows for, say 6 months. Flow = total cash receipts - total cash payments 5. Explain the purpose of capital budgeting systems. Provide help with planning acquisition(disposal) of major plant assets that will be 1 used by the business during many years. Provide outgoing and incoming cash for the life of the asset use assumptions consider the time value of money(net present value). 5b. Explain the contribution of Investment Management Systems; give an example. Oversee organization's investment in stocks, bonds, and other securities. On-line databases provide immediate updates for stock and bond prices. An example is how Value Screen inputs the current price of each stock and calculates the gain or loss the company's investment portfolio would generate if sold now. 6.Give an example of two strategic systems in the area of Finance. Provide an example of how each is used in industry. Financial Condition Analysis Systems: -provide insightful analyses of financial statements and data(e.g., ratios: current ratio, debt:equity ratio) On-line databases can allow for financial analysis of competitors, suppliers, buyers and other organizations Long Range Forecasting Systems: -may use both internal and external data -apply statistical techniques -may use graphics -analyse trends. ex. planning for long-term assets through equity financing 7. Outline 5 areas of production planning and control that could benefit significantly from information systems.(LO7, slide 4) Raw materials acquisition(when, how much) Machine and worker requirements Detailed production schedules Gathering evaluation statistics -sensors, scanners, shop floor terminals -quality control -comparing performance data to plans Cost accounting for manufacturing goods 8. What is the main output of a Master Production Schedule? What are three main inputs? Three main inputs are the accepted sales orders, sales forecast, and current finished goods inventory and the main output is lists of the number of units to be produced each week. 9. What is the main output of the Material Requirements Planning system? What are its 2 main inputs? The main output of the MRP system is a time-phased purchase orders for raw materials. The two main inputs are Bill of Materials and the Master Production Schedule. A Bill of Materials is a list of raw materials needed to produce one unit of finished product and the quantity of each material. 10. What are two main outputs from the capacity requirements planning system? A Route Sheet shows the sequence of required operations and the standard time allowed for each operation(usually person + machine) A detailed production schedule can also be produced from the CRP system. 11. Based on questions 7-10, and considering MRPII, explain, with adequate examples how information systems can assist production management. Information systems can assist production management in many different ways. One being it can allow production managers with detailed forecasts on what materials will be needed to produce the necessary products through the Bill of 2 Materials. They also can provide the Master Production schedule, which is actually a step before using the Bill of Materials, to tell the manager how much products will be produced in a given week. Then a route sheet can be used to figure out how much time will be spent in the production process. With all these different detailed reports, MRP, and CRP combined into MRPII all the necessary information for a production manager to view where production is at at any given time is easily accessible. To sum it up, information systems like MRPII simply make production management a easier task for its managers. 12. Explain the concept of vendor managed inventory and the role of computer system in this. Supplier's computer's tap into our inventory system to view when stocks are low. Computer support in manufacturing extensive, they support information systems 13. Explain the terms: supply chain, supply network, supply chain management. How do information systems assist in this area? Supply chain is the flow of materials, services and information form suppliers of merchandise and raw materials through to the organization's customers. Now it's called a supply network. Supply chain management is the processes and procedures used to ensure the delivery of goods and services to customers at the lowest cost while providing highest value to the customers. Suppliers are gaining access to an organizations production planning schedules to assure an ability to fulfill orders. Producing organizaton is opening its stems to the customer to allow the customer to view inventory and production levels before placing orders. A supply network is the flow of materials from multiple suppliers involved in the process of servicing a single organization. More detailed term than just a supply chain. Information systems can assist in this area to connect suppliers to other organizations, so they know when stocks are low. 13b. Outline one strategic support system in manufacturing. Dell computers' SCM system, Dell uses Ariba SCM to automate its purchasing process. The system is connected to its broad supplier network. This provides Dell with data to id inefficiencies within its supply network; and to negotiate key contracts for goods and services. 14. Describe clearly and completely any TWO systems which support marketing at the operational level. Be able to describe specific outputs Contact management systems: provide information on past contacts with specific customers. Output: call report- # of sales calls made by a salesperson, # and dollar amount of sales made by this person Telemarketing systems: Identify customers and automatically call them, use electronic phone directories, can make notes about calls, in a LAN-based system 200 telemarketers can use the same system at the same time. 15. Describe clearly and completely any TWO systems which support marketing at the tactical level. Be able to describe specific outputs Sales management systems: can help make tactical decisions such as- how sales territories should be shaped, how to allocate salespersons to territories, and what products should be offered to what customers. Examples of outputs 3 are effectiveness of different salespersons with different segments of the market, assessment of the productivity of the sales force and the fertileness of sales territories, and success of products by salesperson, territory, and product type. Pricing systems: help managers set prices for their products and services. Some i
