1.0 Introduction
Information system, which is the most important technique in this information age, is playing an increasingly pivotal role in modern business organisations. The information age is relying on the information and communication technology (ICT), and it is using widely in every corner of the modern organisation (Hussain, 2009). Organisations may use ICT to transform business process and make them more efficient and accurate (Hussain, 2009). Moreover, ICT may be use to create, store and disseminate the business data and translate data into useful information. Managers may use this information to make some correct decisions (Hussain, 2009). Bright Light Limited (BLL) is a company which makes light bulbs and fluorescents. It started ten years ago as a small manufacturer. Nowadays, BLL has three hundred employees as a large company. There are numbers of central departments in BLL like Accounting, Marketing, HRM and Sales. Different departments in BLL handle different types of information system; however, the use of information system is small yet and this cause BLL lack of international competitive force and work inefficiency. Therefore, in the present age, BLL needs a large number of new information systems across all the departments (Hussain, 2009). In this report, I will show how the departments of Bright Light Limited(BLL) using the information system and I will create some new Computer-Aided Design system (CAD) and Computer-Aided Manufacturing system(CAM) across the departments of the BLL. Moreover, this report will descript different types of systems that BLL could acquire in its departments, it may give the international competition to BLL and it may help BLL to develop. Finally, this report will descript the working of shop-floor data collection system and tell managers the requirement of hardware and software, this is one of the most important systems and it may make the works in BLL more efficiency. 2.0 Task 1

2.1system theory concept
There are nine main departments in Bright Light Limited (BLL), which are: Accounting, Marketing, HRM, Electrical engineering and Design, Sales Warehousing, Manufacturing, Logistics and Despatch. Each department in BLL has their own functions and every department are interdependent. In this task, I will use the key systems theory concepts to show how the department use information system. In more detail, I will show the inputs, process, outputs and feedback in three departments as the following model. According to Hafeez (2007), a system can be define as a collection of interrelated parts that taken together from a whole (p15). As Figure2.1 in Appendix shows, all the system will have inputs and outputs. Inputs and outputs can be energy, raw material or labour power; this is depending on the department functions. Feedback is form seniors or customers and it can be used to help process aimed the goals (Harry, 1994). Moreover, inputs derived from and outputs are transferred to the environment of the system. The environment is defined something is not belonging to a system but interacts with the system (Hafeez, 2007). In the Appendix, the report shows the system of the following department: * HRM department (please refer Appendix Figure2.2)

* Accounting department (please refer Appendix Figure2.3) * Electrical engineering and design department (please refer Appendix Figure2.4) 2.2 Information flow
In the Appendix, the report shows three BLL departments with data flow diagram (DFD) and shows how the information flow system work in different departments.

* HRM department (please refer the Appendix)
Figure2.5 shows the level 0 and Figure2.6 shows the level 1 of HRM system. * Accounting department
Figure2.7 shows the level 0 and Figure2.8 shows the level 1 of Accounting. * Electrical engineering and design department
Figure2.9 shows the level 0 and Figure2.10 shows the level 1 of design department 3.0 Task 2
