In order to complete a project in time, companies must determine both the duration of the entire project as well as each of its individual tasks. Very often less experienced companies do not collect data affecting time limit for project completion. Then time required to perform specified activities are determined based on estimation and companies own experience. To minimize the risk error arising as a result of using incomplete historical data and simultaneously increasing the effectiveness of estimating the duration of the project, most project managers with pleasure use the PERT method (Program Evaluation and Review Technique) to estimate the duration of individual tasks of the project on the basis of three intermediate estimation values: optimistic, realistic and pessimistic. This paper will set the duration of an IT (Information Technology) project implementation tasks, determine both critical tasks as well as critical path of the project. Based on estimates deadlines events values, the probability of occurrence time limits shall be also appointed.
