The purpose of this paper was to identify through a systematic literature review the relevant supplier development (SD) practices and the supplier evolution concept in the last three decades. The literature review identified the relevant SD concepts, which figure out a proposed conceptual framework to depict the supplier development process in a holistic way, and its expanded version aims to help organizational managers develop their strategic suppliers. The method used was a systematic literature review ranged from 01/01/1999 until 30/06/2018. The obtained results show us that the supplier's development concepts presented an evolutionary process over time, undergoing a paradigm shift from a transaction-oriented way to a relation-oriented relationship. The proposed expanded framework resulting from this work aims to favor managers to direct their suppliers' practices better. The analysis of the results obtained indicates that the purchasing companies and their suppliers need to intensify the long-term relationships between them to face the challenges promoted by the intense use of new technologies induced by IIoT.

Wind energy is an additional source of renewable energy, those energies that do not harm the environment and fits in the group of alternative energies. Brazil has one of the cleanest energy matrices in the world, mainly a matrix based on hydro power. The country is considered the most promising market for wind energy in Latin America, with an estimated wind potential of 300 GW. The research aimed to identify and define variables that most strongly impact the economic viability of operating equipment and wind farms in Northeast Brazil, identifying the key performance factors for the economic analysis performed, such as technologies, equipment size and productive efficiency. The study focused on wind turbines with installed capacity above 1MW, capable of generating power at more competitive costs. Deterministic models were used in the analysis of investment projects, which included the elaboration of the Discounted Cash Flow (DCF) and the adoption of indicators such as Net Present Value, Internal Rate of Return and Pay-back, complemented with a sensitivity analysis of the main variables impacting the economic viability of wind investments in Northeast Brazil. The cash flow analysis allowed the calculation of the break-even for the different variables analyzed, equipment load factor, wind turbine investment and effective hours available for wind generation, among others. Although for the situation analyzed, wind generation projects in the Northeast of Brazil are economically viable, the profitability of these projects for the assumptions of the calculation assumed is still low, considering they generate a 15 year Pay-back and a return rate of 9.22% as opposed to an assumed financing cost of 7,3% p.a.
