A skill is an ability to perform a specific task or activity to a high level of proficiency.
Within ability6 we manage at task and process level. Therefore, we have to decide if the skill is going to be treated as a type of process or a type of task.
If the skill is a narrow technical skill, for example Excel spreadsheet skills, this should be defined as a task.
The collection of tasks would then be grouped under a process, such as month end reports. (of which Excel proficiency would be identified as a required skill/task)
If the skill is a broader skill, for example Project Management, this should be defined as a process.
The process (Project Management) would be broken down into its component tasks, such as; PRINCE2 Foundation skill, Completed xyz Project management methodology etc .
