In Chile, as in many other areas of the world, water supplies have been poorly managed and water availability is decreasing. In order to manage water resources more sustainably and equitably, it is necessary to understand and predict their supply and use considering the characteristics of a particular zone. This study aimed to develop a conceptual model for water management in the Libertador Bernardo O’Higgins Region in Chile. The model considers the water needs of industries with production activities, human consumption, and the ecological flow of each sub-basin in the area. The results show that the proposed model contributes to the understanding of the critical variables, their agents, and the interaction between the hydric demands, which enables the prioritization of human consumption and the ecological flow. Furthermore, the cross-analysis between the offer and demand indicates that current and predicted consumption levels will only be sustainable up to the year 2031. The findings may be of use to decision-makers seeking to improve water management plans in this area and elsewhere, and to others interested in modeling water management in different areas. © 2022 by the authors.

The objective of this research is to determine the main existing gaps before implementing agile methodologies in IT-SMEs (Information Technology - Small and Medium-Sized Enterprises) with traditional methodolo-gy for project management. To this effect, a qualitative approach to the opinions of three managers, two project engineers, and six programmer analysts of a company is proposed, which is based on semi-structured interviews, considering a convenience sample, in order to understand the existing difficulties in the company under study, contrasting this reality through surveys aimed at 29 IT professionals from other organizations. The results of the analysis reveal that the main gaps for the implementation of agile methodologies in SMEs are organizational culture at odds with agility, lack of commitment from management, and resistance to change. It is concluded that the proposal turns out to be effective for understanding the main gaps to be solved before starting the implementation of an agile methodology in an IT-SME, thus allowing the organization to be aligned with agility.
