Purpose The purpose of this paper is to compare the practices of continuous improvement that are applied in medium and large manufacturing and service companies in two Latin American countries. At the same time, benefits and barriers experienced by these companies with regard to sustainability of continuous improvement are explored. Design/methodology/approach In order to generate a comparative study between two Latin American countries, interviews were conducted with managers linked to continuous improvement in medium and large companies in the State of Puebla and the Metropolitan District of Quito, which are important areas in Mexico and Ecuador, respectively. Data were collected by means of document analysis, semi-structured interviews, and direct observation. Findings Companies in both countries identify the use of various techniques and/or tools for continuous improvement. The results of the empirical evidence show how the impact of the application of the techniques has been beneficial in economic and human terms. Thus, the exploratory study has permitted the identification of the drivers and inhibitors in the maintenance of continuous improvement. Research limitations/implications The research is based on only two areas of the Latin American countries: Mexico and Ecuador. Their results can therefore not be generalized. The approach is applied in a specific environment, namely, the State of Puebla and the Metropolitan District of Quito. This study incorporates the perception of managers, directors, and/or supervisors involved in continuous improvement processes. Practical implications This paper seeks to provide analytical input. The study is of great interest to researchers, managers, consultants, and professionals linked to projects of continuous improvement who wish to incorporate continuous improvement practices which are sustainable over time. A new managerial behavior is the basis of continuous improvement, where the training and development of the human resource increases the commitment to achieve organizational changes. Originality/value This research makes an empirical contribution to the literature through the understanding of practices of continuous improvement in a Latin American context, highlighting the factors that improve or impede the process of continuous improvement. Particularly in Mexico and Ecuador, the empirical evidence on this subject is still scarce despite the existence of theoretical academic literature.

Small- and medium-sized enterprises (SMEs) play an important role in the economic growth of a country and of a sector. They seek to be incorporated into permanent productivity and competitiveness dynamics through a cooperation strategy. This article evaluated the application of management practices to horizontal SMEs networks of the dairy sector in Ecuador by following the constructivist methodology. The literature review and exploratory research indicated an understanding of cooperative work in the networks or Milk Collection Centers (MCCs) and identified the need to evaluate performance when applying management practices as an unavoidable element to enhance their operation and development. The construction phase took as reference a model for the evaluation of management practices in cooperation networks and contextualized it to the Ecuadorian environment. In the evaluation phase, three networks were evaluated, from which results and conclusions were obtained. The developed model identified six criteria with which the evaluations of MCCs were made, whose analysis allowed their performance level to be quantified and a proposal of some specific improvement opportunities for this sector and a group of SMEs.
