The sum of all knowledge resides somewhere.
It is not exactly in Wikipedia or Google. Maybe the knowledge will get captured inside the knowledge blockchain.
In theory the organization has more information than what any one person knows, but an individual has more knowledge than what is shared with organization.
Individuals do get hired for knowledge. Companies train individuals to fill in missing knowledge gaps.
In most companies any intellectual property created while at work belongs to the company.
Knowledge is fluid and it keeps evolving. How do you make sure that new information gets and relevant older information can be found.
Each individual has their own personal knowledge and an organization has its knowledge processes which is a combination of the individual and the collective.
The interaction and the flow between the individual and the collective is truly the knowledge system of an organization.
