The outline of the paper is as follows: in section 1 the goal of this paper is defined. In section 2, the most complex section of the paper, we present the summary of existing knowledge in this matter by reviewing the literature, critical factors of project's success, contingency theory, project typology, project activities classification. Section 3 explains the applied research methodology, the process of building theory from case study. In section 4 the new approach for the project activities typology is introduced, classification of project activities from the angle of five dimensions. In section 5 the application of the proposed approach in the CC/BM is presented, incorporating five identified activities dimension in the buffer sizing procedure. Section 6 contains some conclusions. The goal of this paper is presenting the typology of projects and proposes a new approach for typology of projects activities to define the impact of this factor on the size of inserted buffers in the Critical Chain Buffer Management Method (Goldratt 1997), solution applied in order to cope with inherent uncertainty associated with many projects. The presented classification was compiled from the analysis of the completed or still executed infrastructure and it projects which are performed as well by Polish public institutions, supported by European Union, and private sector.

W artykule analizuje się bufory czasowe jako narzędzie zapewnienia stabilności harmonogramu projektu. Bufory czasowe są znane w literaturze, ale nie ma zgodności co do sposobu wyznaczania ich wielkości. Większość znanych w literaturze metod nie uwzględnia cech charakterystycznych projektu i jego zadań bądź uwzględnia je w sposób niewystarczający. W artykule omawia się kilka metod wyznaczania wielkości buforów uwzględniających te charakterystyki, a następnie, na podstawie analizy rzeczywistego projektu, poddaje się te metody weryfikacji.

The paper presents 3 methods of time buffer size determination and an attempt to verify these methods in a real world project. The methods were compared using 3 criteria: their ability to ensure a schedule stability, the amount of time unnecessarily reserved in buffers with respect to the actual needs and the simplicity of their practical application.
