The purpose of this study was to build an instrument for evaluating the technical-tactical performance of the volleyball players, which enables a decision making by the coach. The study variables were the evaluation of the technical performance of the volleyball players and the evaluation of the tactical performance of a volleyball team. A computer tool for evaluating the technical-tactical performance of volleyball players was developed. Through a computer program established in Microsoft Office Excel, which allowed registering and immediately accessing the necessary information during the development of a game. The variable of technical performance evaluation covers the following technical foundations, with their respective categorization of values. The tactical performance evaluation variable of the team was composed by the distribution of the raised, the technical efficiency percentage of the attack in k1 and k2, and the analysis of raised distribution and efficiency of attack by rotation. The program consists of 6 Excel books that work in an interrelated manner. The first five correspond to the sets played and the sixth corresponds to the summary of all the information entered. The match data were entered in the story sheet, to codify the technical-tactical situations of the game full. The sheets are divided into: Active (Final sheet, general sheet, difference sheet, atqefi sheet, atqk2 analysis sheet and summary sheet per player), Intermediate (Data and ATAQRSM), and Passive (Tables).
