This practical guide presents a new model of consulting - that of the internal project manager. With their help, complex tasks in SMEs can often be solved internally without the need for external assistance. Although there are often significant reservations about external consulting firms, decision-makers frequently see no alternatives. This is mainly because the potential, knowledge, and skills of their own employees are underestimated. Studies show that for SMEs, their own employees are the most important success factor for maintaining a sustainable market presence. The book thoroughly outlines each project phase using an internal project manager, and the necessary methods and tools are explained step by step. Practical examples and more than 170 illustrations assist in the implementation within one's own company.
