PurposeThe purpose of this paper is to evaluate the effects of supplier development programs on the short‐term performance of suppliers and the more long‐term development of their capabilities given the relational learning context of the dyad.Design/methodology/approachData were collected through a survey of strategic suppliers from original equipment manufacturers of the automotive industry located in Mexico.FindingsResults suggest that basic and widely used forms of supplier development hardly lead to improved operational and financial performance of suppliers. More demanding and less frequently used forms of supplier development may lead to improved supplier performance given the suppliers have sufficient absorptive capacity and the presence of an adequate collaborative and relational learning context.Research limitations/implicationsOnly suppliers of firms in the automotive industry were surveyed; participant suppliers were referred by buying firms operating in Mexico.Practical implicationsWhen designing supplier development activities, buying firms need to take into consideration that high involvement and investment on supplier development activities is required when their goal is to improve the supplier base.Social implicationsGovernments organizing supplier development programs should consider the importance of promoting knowledge transfer activities above evaluation and feedback to assure the success of their efforts to develop the national supply industry.Originality/valueThe value of supplier development programs is explored in this paper, taking into account the efforts of the buying firms to transfer knowledge and the moderating effect of the relational and learning context. Relevant recommendations for the design of such programs to buyers, suppliers and government are discussed.

The construction sector is progressively becoming more circular by reducing waste, re-using building materials and adopting regenerative solutions for energy production and biodiversity protection. The implications of circularity on construction activities are complex and require the careful evaluation of impacts to select the appropriate path forward. Evaluations of circular solutions and their environmental efectiveness are often performed based on various types of life cycle-based impact assessments. This paper uses systemic thinking to map and evaluate diferent impact assessment methodologies and their implications for a shift to more circular solutions. The following systemic levels are used to group the methodologies: product (material life cycle declarations and building assessments), organisation (certifcation and management schemes) and system (policies, standards and regulations). The results confrm that circular economy is integrated at all levels. However, development and structure are not coordinated or governed unidirectionally, but rather occur simultaneously at diferent levels. This recursive structure is positive if the methods are applied in the correct context, thus providing both autonomy and cohesion in decision making. Methods at lower systemic levels may then improve production processes and stimulate the market to create circular and innovative building solutions, whereas methods at higher systemic levels can be used, for example, by real estate builders, trade organisations and governments to create incentives for circular development and innovation in a broader perspective. Use of the performance methods correctly within an actor network is therefore crucial for successful and efective implementation of circular economy in the construction sector. ; publishedVersion
