For the area of project work, which largely consists of non-routine activities, reusing already acquired knowledge is advantageous for solving project tasks more quickly and efficiently. How can existing knowledge be documented so that it is easily found by those seeking it? How can one effectively manage knowledge in its unity of presentation and retrieval by the knowledge holder, and presentation and provision to the knowledge seeker? This book provides companies with concrete suggestions. The focus is on opportunities that build on the existing foundation, rather than on large electronic application systems. It includes detailed case studies.
