The paper presents how the critical path method is applied to the management of the unique items production. The case of a complex product was taken into consideration: equipment for detergent automatic wrapping. The first step was the signing of the contract with the beneficiary. Then all the activities which lead to the equipment finalization were taken into account: design, supply, execution, assembly, testing and delivery. All these were implemented in the Microsoft Project® software application, which yielded important information for the project manager: critical path, critical activities, finalization deadline and related costs. According to the data of the first version, supplementary resources were added for some critical activities, which yielded the reduction of the project execution duration.
