REVISIÓN DE MÉTODOS DE DIMENSIONADO DEL BUFFER EN EL MÉTODO DE LA CADENA CRÍTICA

Abstract

Buffers are fundamental elements to protect the programming in Critical Chain Project Management. Buffer's sizing has a significant impact on project’s timeline. Based on the 50% Rule proposed by Dr. Goldratt and considering the criticism of the lack of justification of the method, other more scientific procedures have been developed. This paper identifies seven sizing methods obtained from an exhaustive bibliographic review. A practical application of these methods in the same project is presented, and comparisons of the results obtained are shown. Knowing the different methods for buffers’ calculation, and depending on the number and accuracy of the data available for programming, the project manager will choose the most appropriate procedure according to project’s size, cost and risk.
