The sysadmin is on call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it. They may also need to have teamwork and communication skills; as well as being able to install and configure hardware and software. Sysadmins must understand the behavior of software in order to deploy it and to troubleshoot problems, and generally know several programming languages used for scripting or automation of routine tasks.
A typical sysadmin's role is not to design or write new application software but when they are responsible for automating system or application configuration with various configuration management tools, the lines somewhat blur.

In some organizations, computer security administration is a separate role responsible for overall security and the upkeep of firewalls and intrusion detection systems , but all sysadmins are generally responsible for the security of computer systems.
In larger organizations, some of the tasks above may be divided among different system administrators or members of different organizational groups. For example, a dedicated individual s may apply all system upgrades, a Quality Assurance QA team may perform testing and validation, and one or more technical writers may be responsible for all technical documentation written for a company.
