Answer:

You should determine the knowledge that your organization needs to operate their processes and make products and services according to requirements.
You should maintain this knowledge and make it available as needed, for example, when new people are contracted.
Consider your current knowledge when making changes, and determine how you will gain additional or updated knowledge if necessary for the changing needs.
