Performance rental technicians prepare, maintain, issue, transport, set‐up, program, operate, take in, check, clean and store audiovisual, performance and event equipment. Their work is based on plans, instructions and order forms.

Performance video operators control the (projected) images of a performance based on the artistic or creative concept, in interaction with the performers. Their work is influenced by and influences the results of other operators. Therefore, the operators work closely together with the designers, operators and performers. Performance video operators prepare media fragments, supervise the setup, steer the technical crew, program the equipment and operate the video system. Their work is based on plans, instructions and other documentation.

Software analysts elicit and prioritise user requirements, produce and document software specifications, test their application, and review them during software development. They act as the interface between the software users and the software development team.

Software and applications developers and analysts conduct research; plan, design, write, test, provide advice on and improve information technology systems such as hardware, software and other applications to meet specific requirements. Competent performance in most occupations in this sub-major group requires skills at the fourth ISCO skill level. Tasks performed usually include: researching information technology use in business functions and identifying areas in which improvements could be made to maximize effectiveness and efficiency; conducting research into the theoretical aspects of and operational methods for the use of computers; evaluating, planning and designing hardware or software configurations for specific applications; designing, writing, testing and maintaining computer programs for specific requirements; evaluating, planning and designing Internet, Intranet and multimedia systems. Occupations in this minor group are classified into the following unit groups: 2511 Systems Analysts 2512 Software Developers 2513 Web and Multimedia Developers 2514 Applications Programmers 2519 Software and Applications Developers and Analysts Not Elsewhere Classified.

This unit group covers software and applications developers and analysts not classified elsewhere in Minor Group 251: Software and Applications Developers and Analysts. For instance, the group includes those professionals specializing in quality assurance, including software testing. In such cases tasks would include - (a) developing and documenting software testing plans; (b) installing software and hardware and configuring operating system software in preparation for testing; (c) verifying that programs function according to user requirements and established guidelines; (d) executing, analysing and documenting results of software application tests and information and telecommunication systems tests; (e) developing and implementing software and information system testing policies, procedures and scripts. Examples of the occupations classified here: - Quality assurance analyst (computers) - Software tester - Systems tester.

Software architects create the technical design and the functional model of a software system, based on functional specifications. They also design the architecture of the system or different modules and components related to the business' or customer requirements, technical platform, computer language or development environment.

Software developers implement or program all kinds of software systems based on specifications and designs by using programming languages, tools, and platforms.

Software developers research, analyse and evaluate requirements for existing or new software applications and operating systems, and design, develop, test and maintain software solutions to meet these requirements. Tasks include - (a) researching, analysing and evaluating requirements for software applications and operating systems; (b) researching, designing and developing computer software systems; (c) consulting with engineering staff to evaluate interfaces between hardware and software; (d) developing and directing software testing and validation procedures; (e) modifying existing software to correct errors, to adapt it to new hardware or to upgrade interfaces and improve performance; (f) directing software programming and development of documentation; (g) assessing, developing, upgrading and documenting maintenance procedures for operating systems, communications environments and applications software; (h) consulting with customers concerning maintenance of software systems. Examples of the occupations classified here: - Programmer analyst - Software designer - Software developer - Software engineer Some related occupations classified elsewhere: - Applications programmers - 2514.

Software testers perform software tests. They may also plan and design them. They may also debug and repair software although this mainly corresponds to designers and developers. They ensure that applications function properly before delivering them to internal and external clients.

Sound designers develop a sound design concept for a performance and supervise the execution of it. Their work is based on research and artistic vision. Their design is influenced by and influences other designs and must be conform with these designs and the overall artistic vision. Therefore, the designers work closely with artistic directors, operators and the artistic team. Sound designers prepare audio fragments to be used in a performance, which can involve recording, composing, manipulating and editing. Sound designers develop plans, cue lists and other documentation to support the operators and production crew. Sound designers sometimes also work as autonomous artists, creating sound art outside a performance context.

Sound editors create the soundtrack and sound effects for motion pictures, television series or other multimedia productions. They are responsible for all the music and sound featured in the movie, series or videogames. Sound editors use equipment to edit and mix image and sound recordings and make sure that the music, sound and dialogue is synchronised with and fits in the scene. They work closely together with the video and motion picture editor.

Sound mastering engineers convert finished recordings to the desired format such as CD, vinyl and digital. They ensure the quality of the sound on all formats.

Sound operators control the sound of a performance based on the artistic or creative concept, in interaction with the performers. Their work is influenced by and influences the results of other operators. Therefore, the operators work closely together with the designers and performers. They prepare audio fragments, supervise the setup, steer the technical crew, program the equipment and operate the sound system. Their work is based on plans, instructions and other documentation.
