Planning processes undergo unexpected changes with frequent re-planning, resulting in disconnection with business strategies, loss of coherence between planning horizons, and failure to achieve expected organizational results. The purpose of this paper is to identify the factors that cause changes, selecting the most critical ones, as well as their effects on planning processes. To achieve this objective, a systematic literature review and an empirical study in an oil and gas company were carried out. Five factors of greater influence on the processes were identified: organizational pressures, information inconsistencies, schedule changes, estimates and shared resources. In this study, the analysis of the "schedule changes" factor is presented, with its possible causes and their effects. Most respondents indicated that schedule changes is the factor of greatest impact in portfolio management, project management, and shared resources management, among the five studied ones, due to repriorizations, project insertion and exclusion, limitations of resources not considered in the portfolio, among others. This work presents an innovative look at a complex scenario that is the multi-project portfolio management with shared resources in the petroleum industry, being an important input for the organizations in promoting a more effective project management. Project managers and teams will be able to identify and treat possible factors present in their processes, obtaining better results in the implementation of new enterprises.
