For someone looking at knowledge management for the first time I would suggest to understand that knowledge management is a matter of not only tools and techniques but it also involves understanding the processes that you are going to follow, and also understanding the culture of the organization.
Many well thought through efforts fail because they are not in contact with the general culture of the organization. In order to get an effective knowledge management environment you need to have people that are willing to share their knowledge in the first instance. Understanding and appreciating the evolution that takes place in getting the right attitudes and the sharing of information is very important. Next, it is important to find the tools, capabilities and processes for the organization.
Finally, and most important is making knowledge management part of the normal processes that the organization carries out. Too often knowledge management has been looked upon as a waste for people to do in addition to their job. - Peter Fuchs of the Brain Technologies
