What Computer Systems Analysts Do
Analysts create diagrams to help programmers and architects build computer systems.
Computer systems analysts study an organization’s current computer systems and procedures and design information systems solutions to help the organization operate more efficiently and effectively. They bring business and information technology (IT) together by understanding the needs and limitations of both.
Computer systems analysts typically do the following:
- Consult with managers to determine the role of IT systems in an organization
- Research emerging technologies to decide if installing them can increase the organization’s efficiency and effectiveness
- Prepare an analysis of costs and benefits so that management can decide if IT systems and computing infrastructure upgrades are financially worthwhile
- Devise ways to add new functionality to existing computer systems
- Design and implement new systems by choosing and configuring hardware and software
- Oversee the installation and configuration of new systems to customize them for the organization
- Conduct testing to ensure that the systems work as expected
- Train the systems’ end users and write instruction manuals
Computer systems analysts use a variety of techniques such as data modeling to design computer systems. Data modeling allows analysts to view the processes and data flows even before programs have been written.
Once programs have been written, analysts conduct in-depth tests and analyze information and trends in the data to increase a system’s performance and efficiency.
Analysts calculate requirements for how much memory and speed the computer system needs. They prepare flowcharts or other kinds of diagrams for programmers or engineers to use when building the system. Analysts also work with these people to solve problems that arise after the initial system is set up. Most analysts do some programming in the course of their work.
Most computer systems analysts specialize in certain types of computer systems that are specific to the organization they work with. For example, an analyst might work predominantly with financial computer systems or engineering computer systems.
Systems analysts help other IT team members understand how computer systems can best serve an organization by working closely with the organization’s business leaders.
In some cases, analysts who supervise the initial installation or upgrade of IT systems from start to finish may be called IT project managers. They monitor a project’s progress to ensure that deadlines, standards, and cost targets are met. IT project managers who plan and direct an organization’s IT department or IT policies are included in the profile on computer and information systems managers.
Many computer systems analysts are general-purpose analysts who develop new systems or fine-tune existing ones; however, there are some specialized systems analysts. The following are examples of types of computer systems analysts:
Systems designers or systems architects specialize in helping organizations choose specific types of hardware and software systems. They translate the long-term business goals of an organization into technical solutions. Analysts develop a plan for the computer systems that will be able to reach those goals. They work with management to ensure that systems and the IT infrastructure are set up to best serve the organization’s mission.
Software quality assurance (QA) analysts do in-depth testing and diagnose problems of the systems they design in order to make sure that critical requirements are met. They also write reports to management recommending ways to improve the systems.
Programmer analysts design and update their system’s software and create applications tailored to their organization’s needs. They do more coding and debugging than other types of analysts, although they still work extensively with management and business analysts to determine what business needs the applications are meant to address. Other occupations that do programming are computer programmers and software developers.
