Tools are devices you use to carry out functions efficiently. Tools aid you in getting things done. To succeed in your work, tools are essential. They supplement and enhance your own skills and capabilities. You must keep your tools sharp and in working order for them to be useful. Often, you have to adapt them to fit your needs and style.
Tools can range from apps that keep you organized, to methods to track projects and performance, to specific approaches to interviewing and hiring, for example. There are many places where tools are defined and recommended for you. One of my favorites is www.manager-tools.com.
