Which KM tool to choose

Knowledge Management can be anything that in one way or another facilitates communication, cooperation, and sharing of knowledge within and between organizations.

This opens up the field of possible knowledge management tools, methods, and techniques for anything from simple box lunches to complex and expensive enterprise knowledge management suites. There is no one KM tool, technology, or method. In KM „Anything goes!“ For this reason KM is a very creative and quickly changing field.

Chief Knowledge Officers (CKO) must know about a great variety of different kinds of solutions, IT-based, organizational, and interpersonal. Not only that, but CKOs also have to make decisions about which tool, technology or measure is the best in every different situation to implement.
From the CAS Course in Knowledge Management by IKF Luzern

It is a major principle of my work to not apply a tool just because it is a KM tool (and has a cool name), but to find the most appropriate one for every situation. A KM tool or method needs to bring exactly the outcome wished for, with the least possible effort and the smoothest possible implementation in the day-to-day business. The vast number of possibilities may seduce to choose something fancy that sounds impressing. But it is the simple tools, the ones already used in an organization, the ones people are familiar with, which are the tools to choose.
