This thesis focuses on analysing 7 + 1 types of waste according to the Lean organisation of manufacturing on a chosen company Bezak MTP d.o.o., with the goal of presenting the analysed waste to the company and eliminating said waste. In the first part, three basic and one side hypothesis were established, and the main hypothesis examines the claim that the company is not aware of the 7 + 1 types of waste according to the Lean organisation of manufacturing. This thesis explains theoretical principles of Lean and its waste. In the second part of the thesis, one waste for every type of waste according to Lean is examined in detail. Some waste was tracked with video surveillance, determined by bookkeeping notes and waste in the form of “unused human potential”, on examples of the Kaizen proposal. The calculation of yearly waste was carried out by analysing and examining. Also, according to the presentation to the company on waste that occurs in manufacturing, it was concluded that the company is partly aware of the waste, and that the company does not know how to eliminate it.
