There is no real definition of collaborative knowledge management or CKM. But, you can think of CKM as a process in which organizations generate value from intellectual and knowledge-based assets. When you get the value of those assets, you have to share with your employees, departments, and even competition with another company to design the best practices of that knowledge.
We can also define collaborative knowledge management, as well as tools that support team members and share information that can contribute to the knowledge base system. The core is basically what all the needs of every person to make a wide range of advantages in this world and this is all considered to be a collaborative knowledge management.
For example, the company has been researching a new product that they want to create. They are a company of ideas but to make money from this product, they will need to include people who own the material to create a product, they must include a designer who will take the material and actually make a product, and they must include the marketing people will market and sell the product. This does not even mention the lawyers and business people that you need to include to get the patent.
This is an example of collaborative knowledge management. This company has taken the knowledge and share them with other several different companies to provide the knowledge that the value for the group as a whole because everyone will make a profit. Management types occur every day but in today's technology, the business people who try to take advantage of actual ideas about collaborative knowledge management and installing it into a software that will make it more concrete and applicable. With other words, they tried to put a value on the idea that places values on each other the idea of knowledge. If there are ways to make money, no matter how many layers you create from an idea
