A job specification could be considered a more precise job description that details the exact educational degrees, experience, skills, and requirements for a role. In most cases, these terms are used interchangeably and nearly always describe the same document.
To make it easier to create and manage job descriptions that are complete, clear and consistent, it is best to start with a job description template. The number of templates you need will depend on the variety of jobs in your organization, but as with all things - less is more. But while many HR professionals and managers agree that job description templates are a foundational talent management tool, many struggle with knowing exactly what to include in their templates.
