In this assignment I will be discussing software used in my chosen department and the key work processes, identify and explain the key mobile devices used and how the internet used by the employees, and which would be the best methodology to improve systems.

Task 1

In this assignment I have chosen the accounting department, I will be discussing key work process within this department and the software that is used for these processes. According to Z.Hussain (2009) a system ‘is a set of interrelated parts, arranged into an organized whole or orderly structure’ systems within accounting are very systematic a methodical as all decisions is made according to plans. A system contains many sub systems, these are smaller systems (departments) within the system that work to run the system effectively and efficiently, these sub-systems may be different but they are interrelated as they share data/information between each other to goals that help towards filling the larger goals of the accounting system.

Figure.1 – The chart above shows that accounts can be separated into two sub systems, and can further be decomposed into sub-sub systems. By decomposing a system it shows the different tasks that occur in the system, what these tasks are and how they are done to meet the main targets of the department.

When systems are decomposed, each system has its own characteristics, which can be explained by the business organizational hierarchy. This hierarchy consists of EIS (executive information system), MIS (management information systems), and TPS (Transaction processing system). An example of this would be at Phones4u the bottom of the hierarchy there would be sales consultants, in the MIS there would be managers and at the top would be head office/ executives/ accounts department. Information is passed and processed as it moves up the hierarchy, so the output of the TPS would be the input of the MIS and the output of the MIS will be the input of the EIS.

Figure.2

Figure.2 shows that each system has different characteristics, as each stage has different responsibilities and carries out different purposes to ensure the end target is reached. So at the TPS stage there is a high number of employees where as at the EIS stages there are fewer employees, the same way at the TPS stage According to Z.Hussain (2009) decision making is more of a routine and is repetitive and at the strategic level it is more of a one of decision and is focused more on the user.

All the systems have inputs, process and then outputs, the processes are usually done by software, and data is processed into useful information which can then be used to make decisions or can be processed further.  I’m going to be focusing on the financial sub system, and the sub-sub –system of sales.  At phones4u at the operational level (TPS) it would be selling mobile phones, the input was scanning the barcode of phones, which would then be processed with the ‘point of sale’ system which takes the phone out of the stock showing that it has been sold, and the output is a receipt as well as the change of stock in the system. This output is then used by managers at the management level (MIS), The input at this stage is the receipt which electronically be sent to the mother system in store, the processing of these receipts is done by the ‘end of day’ system that calculates money come into store, money gone out, and left over product, the output of this level is a manager’s report. This report is then sent to head office which sends it to all the departments that need the data for example accounts, this is the DSS system accounts then use this data as input and use software such as SAGE to input the data and process it to give an output of balance sheets/cash flow/budgeting etc . These documents  are then sent to the strategic level executives, who then use the data as an input processing at this stage consist of evaluating and looking at the figure of the business to then make decisions on next year’s/months target, budgets etc.  In the same way raw data is collected at TPS stage for all the sub-sub-systems and is processed and moved up the hierarchy to be processed further and at the EIS system level the data is then processed to give an end result to how the company is doing and what should be.

Much Software are used According to the usage of them and the size of the business that they are used in. The different software’s used are chosen according to how useful they will be while working with them. There are a lot of them that can be used but some of the major ones are listed below:

Task 2

A wireless device is any device that can send information wirelessly from one device to another so it does not consist of any physical wires, mobile devices are portable, and can connect to the internet wirelessly. In my chosen department it is very important to be able to access data, emails etc on the go without being inside the office. Mobile devices that allow an individual to access are very useful for an individual to carry out their duties outside the office as well as inside. These devices help to save a business money as well as ...
