In Colombia, micro, small and medium-sized enterprises are searching for tools contributing to perdurability and competitiveness of their businesses, overcoming the most common problems of micro, small and medium-sized enterprises: short lifecycles and low growth. Since these organizations account for over 90% of the domestic production sector and are responsible for 35% of GDP as reported by DANE, it is important to the country that these organizations be competitive and sustainable. As a consequence of this, a methodology was developed for management integration for these enterprises. The research was developed following a sequential explanatory design, and the methodology designed was submitted to an expert panel taking into account pertinence and relevance criteria. Likewise, the statistical method was considered for content validity based on Lawshe formula with the correction factor proposed by Tristán-López. According to the results, the proposed methodology makes it possible for management to be integrated, as shown by the results of the content validity criteria, such as pertinence (IVC= 0.8542), relevance (IVC= 0.9167) and Cronbach’s alpha (a=0.9886). It is concluded that the methodology designed provides the input required for management integration based on the strategic direction and is applicable to the studio scenario.
