"What does this mean? Well, John divides KM projects into two groups, judged by the broader goals the project is designed to accomplish (separated by a Big K and little k, to be exact). “Little k” projects aim to capture new knowledge gleaned through solving customer problems and sharing them with employees and customers, while “Big K” projects are much more broad.
In our area of expertise, which John defines as “Big K,” we’re finding that organizations are truly struggling to keep track of information housed in an increasingly diverse and populated amount of internal and external systems. This means that KM projects are always ongoing; the systems in place to house relevant knowledge are never fully up to date." from source: http://www.customerthink.com/blog/
