Supply chain integration is a key factor in improving business performance. Despite this growing interest, little research has highlighted this issue that will determine the survival of many companies. The purpose of this study was to examine the relationship between the supply chain integration practices (SCMP) and the financial and operational performance of Tunisian manufacturing companies. To achieve this, a questionnaire was used as a research tool for data collection. Multiple regression analysis using SPSS26 software was used to answer study questions and examine study hypotheses. According to research, SCMP includes customer relationship management (CRM), supplier relationship management (SRM), buyer-supplier collaboration (BSC), joint knowledge creation (JCK), level of information sharing (IS), goal congruence (GC) , risk management (RM), internet usage (IU), quality management (QM) , except information quality (IQ), collaborative planning, forecasting and replenishment practices (CPFR), and just-in-time (JIT), are all significantly related to the financial and operational performance of the companies surveyed. Some recommendations are proposed to help managers better manage knowledge throughout the supply chain.

The aim of this paper is to propose a combined approach for studying entrepreneurial opportuni-ties based on effectual variables. The proposed mixed approach is carried out in three phases. First, entrepreneur’s effectuation variables are selected via a cognitive map and MICMAC meth-od. Second, a Neural Network (ANN)-based model is performed to highlight the emergence of potential entrepreneur’s conception which rely on effectuation key variables with survival and performance. Finally, ANN model is applied based on effectuation variables. Indeed, many con-firmations and interesting findings have been concluded. The results of the proposed approach are essential to understand Tunisian entrepreneur’s thinking and acting in entrepreneurship pro-cess. We make enrichments to the way of theorizing and practicing entrepreneurship, avoiding the idea of mythic entrepreneur.
