The local productive arrangements (LPA) are organizational mechanisms that enable the continuous performance of small businesses in production processes and business management models. To promote continuous improvement is essential that companies make decisions based on data that reflects business’ performance (performance measurement) and promote the cluster performance. This way, the aim of this article is to describe the performance measurement process that will support the corporate management of Micro and Small enterprises (SME) of a Local Productive Arrangement in Maringá, State of Paraná, Brazil. To develop this paper, the bibliographic search and action research methods were used. The field research was developed from the cooperation project (PROJVEST) conducted at the LPA, which goal is to deploy improvement actions in project’s participating companies. Metrics and performance indicators constructed from the diagnosis in the areas of Production, Quality and Ergonomics in companies will be presented. Among the main results, can be pointed out that the performance management of LPA is promoting the introduction of corporate management practices in SMEs, stimulating business cooperation, the continuous innovation in manufacturing processes and product quality and business processes.

Estudo sobre a comunicação organizacional e a capacidade de inovar em empresa de pequeno porte. A questão norteadora busca responder se a comunicação organizacional pode fazer avançar e/ou apoiar a inovação em micro e pequenas empresas. O objetivo central é analisar a relação existente entre a inovação e a comunicação organizacional. Aplicou-se o método estudo de caso e a pesquisa documental para interpretação de instrumento diagnóstico denominado “Radar da Inovação” em uma empresa de pequeno porte, localizada no interior de São Paulo. O diagnóstico é realizado com base em dimensões avaliativas que visam verificar a maturidade e o grau de inovação em micro e pequenas empresas. Por meio da avaliação dessas dimensões foi possível construir quadros analíticos e destacar a influência da comunicação organizacional na promoção da inovação. Os resultados apontam que todas as dimensões do “Radar de Inovação” podem melhorar sua performance por meio da comunicação organizacional.

This paper is a study on corporate communication and the ability to innovate in small businesses. The guiding question seeks to respond whether organizational communication is able to make progress and / or support innovation in micro and small companies, and the main objective is to analyze the relationship between innovation and organizational communication. It was applied the case study method and document research for interpreting a diagnosis instru- ment called “Innovation Radar” in a small business company located in the countryside of São Paulo state. The diagnosis is made based on assessment dimensions aimed at checking the maturity and the degree of innovation in micro and small companies. By evaluating these di- mensions it was possible to build analytical frameworks and highlight the influence of corporate communication in promoting innovation. The results indicate that every dimension of the “In- novation Radar” can improve their performance by means of corporate communication.

Methods of recording soil erosion using photographs exist but they are not commonly considered in scientific studies. Digital images may hold an expressive amount of information that can be extracted quickly in different manners. The investigation of several metrics that were initially developed for landscape ecology analysis constitutes one method. In this study we applied a method of landscape metrics to quantify the spatial configuration of surface micro-topography and erosion-related features, in order to generate a possible complementary tool for environmental management. In a 3.7 m wide and 9.7 m long soil box used during a rainfall simulation study, digital images were systematically acquired in four instances: (a) when the soil was dry; (b) after a short duration rain for initial wetting; (c) after the first erosive rain; and (d) after the 2nd erosive rain. Thirteen locations were established in the box and digital photos were taken at these locations with the camera positioned at the same orthogonal distance from the soil surface under the same ambient light intensity. Digital photos were converted into bimodal images and seven landscape metrics were analyzed: percentage of land, number of patches, density of patches, largest patch index, edge density, shape index, and fractal dimension. Digital images were an appropriate tool because they can generate data very quickly. The landscape metrics were sensitive to changes in soil surface micro-morphology especially after the 1st erosive rain event, indicating significant erosional feature development between the initial wetting and first erosive rainfall. The method is considered suitable for spatial patterns of soil micro-topography evolution from rainfall events that bear similarity to landscape scale pattern evolution from eco-hydrological processes. Although much more study is needed for calibrating the landscape metrics at the micro-scale, this study is a step forward in demonstrating the advantages of the method.
