In times when the level of organization within a company can become a crucial competitive factor, the demand for organizational consulting is also increasing. To save time and money, many companies have now established this consulting function internally. The scope of internal organizational consulting is as diverse as the names under which it operates: in-house consulting, organizational development, quality management, personnel development, controlling, and many more. What is still lacking is not only a shared professional identity among internal consultants but also a collectively shared knowledge base. Joana Krizanits provides a well-founded overview in this book of the tasks, tools, and key competencies of internal organizational consultants. Her case studies from industry, administration, church, telecommunications, media, and politics highlight the commonalities.
