1 CHAPTER 6 6 People Syllabus outcomes Describes and compares key roles and responsibilities of people in the field of information and software technology. Overview This chapter examines the roles and responsibilities of people in the field of information and software technology. Careers are divided into three sections: system development; operations and maintenance; and end user support. Each section describes a range of career opportunities and career paths.

2 6.1 System development People in system development are involved in the planning, design and construction of a computer system. There are a number of career opportunities, such as project managers, systems analysts, programmers, software engineers, computer engineers, multimedia specialists and web designers. Project managers Project managers supervise all aspects of a project (see Figure 6.1). Project managers are required to determine the goals of the project, a costing of the project and ensure the project is delivered on time. Project managers are also responsible for resolving any conflicts and checking the work of each member of the team. A project manager only needs a broad understanding of the information technology industry. However, project management does require good interpersonal and Figure 6.1 Project managers supervise their teams leadership skills. Systems analysts Systems analysts solve computer problems and enable information technology to meet the needs of the user. They help an organisation realise the maximum benefit from its investment in equipment and personnel. Systems analysts are involved in the planning, implementation and maintenance of the computer system. They must have good management and personal skills to be able to interview users of the system, determine their hardware and software requirements and develop a plan of action. Most systems analysts have university degrees in either computer science or business. They must have a broad knowledge of computers and keep up-to-date with recent developments in information technology. They are often required to test new products. Systems analysts are given a variety of titles such as computer analyst, systems consultant, or systems officer. 128 HI Tech: Information and Software Technology

3 Programmers Programmers design and write software. A programmer depends on a systems analyst to provide a detailed description of the user s requirements. This description is called the design specifications. A programmer writes programs using a programming language such as Visual BASIC, PROLOG, Java or C++. It is common for several programmers to work together as a team under a senior programmer s supervision. Programmers usually have completed a degree at university. There are two types of programmers, the systems programmer and the application programmer. A systems programmer writes the systems software such as the operating system. For example, they could make changes to the way the CPU communicates with peripheral devices or the relationship between workstations on a network. An application programmer writes software to handle a specific job such as a program to track inventory. The software may be written by revising an existing software package. Application programmers are usually focused on business, engineering or science. Software engineers Software engineers design, create and modify software to solve a computer problem. They are focused on developing software products including the certification, maintenance and testing of the software. Most software is very large and complex. It is often built by a team of experts guided by a software engineer. The team includes programmers, engineers, designers and marketing people. Software engineers must have good programming skills and a detailed understanding of software technologies. They are more concerned with developing algorithms than writing the program code. Project management is an important feature of software engineering. Software engineers require a university degree in information technology and programming (see Figure 6.2).

4 IT skills in greatest demand at present are in the areas of client server applications, Internet, multimedia, database management and system software support. Multimedia specialists Multimedia specialists are involved in the integration of text, graphic, audio, animation and video. They could be involved in authoring commercial CD and DVD products, designing websites or creating promotional demonstrations. Multimedia specialists require a combination of skills and experience in different areas. The development of a multimedia product may require content providers and technical staff: Content providers are people who provide the material for the multimedia product. This may include text, drawings, video footage and audio tracks. Generally these people are skilled in their field without necessarily having any technical skills in the software or hardware areas. Technical staff modify the material developed by the content providers into the appropriate format for the final product. They include design staff who work to develop the overall theme and look of the product. Web designers Web designers are responsible for the creation and management of a website (see Figure 6.3). They must have a good knowledge of programming, excellent writing skills and a detailed understanding of design. Web designers must be able to sell a design idea to their client. They work closely with clients and must develop websites to meet their client s needs. Web designers are often required to work long and irregular hours to meet deadlines. They must be flexible and able to work under pressure. Web designers usually operate within a team and must enjoy working closely with people. Web Figure 6.3 A web designer works closely with others to develop products to meet a client s needs 130 HI Tech: Information and Software Technology

5 designers need to be competent in database development and have a high proficiency in HTML and Java. Computer engineers Computer engineers design and invent new hardware and software. They are involved in a range of projects such as the design, development, testing and supervision of new integrated circuits. Computer engineers are attracted to new developments such as robotics and machines with artificial intelligence. Computer engineers usually construct prototypes before building the new product. They work as part of a team. A career as a computer engineer requires a university degree in engineering or computer science.

They ensure the system is achieving its purpose. Career opportunities include managers, computer operators, technicians, data entry operators, network administrators and database administrators. Figure 6.4 An information systems manager oversees the computer operation in an organisation Managers Managers oversee the computer operation and ensure that personnel and machines are working efficiently. Managers must have leadership skills as well as technical knowledge about systems development, so a degree in business and information systems is generally required. They have a variety of titles, with slightly different roles, including information systems manager (see Figure 6.4). An information systems manager plans and oversees all the information resources in the organisation. 132 HI Tech: Information and Software Technology

7 Computer operators Computer operators look after computing resources in a large computer system such as a mainframe. Their tasks often include preparing, starting up, and running the computers and peripheral devices. A computer operator is responsible for the maintenance of hardware and software, security, virus scanning, regular backups and providing consumables. If the equipment breaks down they attempt to fix the problem and, if necessary, liaise with a technician to fix the problem. Many computer operators receive their training on-the-job, although university qualifications are becoming necessary. They need a logical mind and to be able to work under pressure. Technicians Technicians install, maintain and repair the hardware of a computer system. To prevent the computer from breaking down, they perform routine checks and service. This may involve checking for loose connections, cleaning any moving parts and running diagnostic programs to check that everything is working correctly. If a component such as a motherboard is not working they replace it and take it back to a workshop for repair. Technicians must have a thorough understanding of information technology and usually have a strong background in electronics. Computer service technician Fadia is a computer service technician who enjoys her work. She is dealing with cutting edge technology each day. Fadia gets to use equipment that other people dream about. It is exciting playing with the latest CPU and using the best quality graphic cards. Fadia travels to homes or offices each day to fix a client s problem. The hardest task for a technician is finding the cause of the problem. It often takes some detective work. You need a logical mind to identify the problem. Fadia not only fixes computers but also assembles them. She inserts components onto the motherboard and connects peripheral devices. Fadia s role involves setting up computers for people who have just purchased a new system. She spends most 6 People 133

Tasks 1 Fadia gets to use equipment that other people dream about. Describe the latest equipment that people dream about. 2 Does a career as a computer service technician interest you? Give reasons for your answer. Data entry operators Data entry operators are people who accurately and quickly enter, modify and delete data. Data entry operators work with large computer systems and are trained on-the-job, although good typing skills are required. Smaller companies may employ a secretary whose job would include data entry. Network administrators Network administrators are responsible for the security and administration of a network. They also design and implement systems to keep the network working in the event of a power failure or emergency. The duties of a network administrator include installing new hardware and software, maintaining peripherals on the network, training staff, changing passwords, enforcing licensing agreements, developing a storage system and providing routine backups. Network administrators need a good understanding of network hardware and a detailed knowledge of at least one major network operating system (see Figure 6.5). Network related problems are often very complex so a network administrator should enjoy solving challenging problems. A network administrator is also required to adapt to new technology and to have good communication skills.

Briefly outline the career paths for each course, the content taught and any requirements for admission. 6.3 End user support An end user or user is a person or a group of people who make use of the information technology. They operate the computer system to perform a particular task. Users have different levels of skills, from inexperienced beginners to information technology professionals. They require support in a range of tasks, such as using a piece of software, installing new equipment or simply understanding the basics of a computer system. Career opportunities involved in end user support include training specialists, support staff, consultants and sales staff. Training specialists Training specialists teach users how to operate their computer systems. Training is needed in the installation of a new computer system and to ensure users are efficiently using software applications. There are many opportunities for qualified instructors in schools, TAFEs, universities and private industry. Trainers present information to individuals, at meetings, workshops or conferences (see Figure 6.6). They may be asked to develop training documentation, multimedia presentations or create a tutorial for the computer. It is essential that trainers keep pace with the latest developments in information technology. Trainers usually require industry qualifications such as a Microsoft Certification. Future growth in demand for IT skilled people is expected to increase by over 24 per cent in the next three years. Support staff Support staff provide hardware and software support to a range of users. Their roles and responsibilities may include advice on backup and virus detection, undertaking preventative maintenance, installing hardware and software, documenting solutions and responding to problems. Support staff need a broad knowledge of 136 HI Tech: Information and Software Technology

Help desk staff receive notification of problems by phone or . Help desk staff enter details of problems into help desk software, prioritise problems, solve problems and, if necessary, refer problems to more qualified staff. Most information technology organisations employ help desk support staff to answer a wide range of questions on their products. Help desk Alexis works on the help desk for a business called IT Results. His day involves answering a constant stream of phone calls from people who have forgotten their passwords to people whose computers do not work. Most problems can be dealt with immediately. However, if this is not possible, Alexis records the problem and passes it to a technician. Alexis enjoys his job but it can be quite stressful. When people have deadlines and their computer is not working they can get very angry. For this reason, help desk staff need excellent communication skills and the ability to solve problems quickly and effectively. 6 People 137

12 Help desk staff are most needed when there is a new or updated system being installed. Users will have questions and need help until they become familiar with the new software, or hardware s operation. Alexis has been able gain a huge variety of knowledge and skills working on the help desk. The experience gained has the potential to open career opportunities in the future. Alexis would like to move from help desk into help desk management where you actually visit the user or client to fix problems. Tasks 1 Would you be interested in working on a help desk? Give reasons for your answer. 2 Developments in information technology will make the help desk unnecessary. Do you agree with this statement? Give reasons for your answer. Consultants Consultants are experts who charge a fee for providing advice or service. They draw on their experience gained in one or more areas, such as education, finance or engineering. Consultants must have good technical skills and the ability to communicate their suggestions effectively to their clients (see Figure 6.7). Figure 6.7 Searching for a job on the Internet (screen capture taken 23 July 2004) Sales staff Sales staff are employed by an organisation to sell the company s products. Sales staff provide information to customers to enable them to choose a product that meets their needs. Sales staff in information technology may have customers who want to purchase a new computer, a piece of software or who are inquiring about a new computer game. They 138 HI Tech: Information and Software Technology
