The sector provides more than 463 thousand jobs and represents 7.4% of the GDP. Most of the companies, mostly family businesses, do not have enough knowledge to implement a management model according to productivity standards and expected level of service. This article proposes a production model for the clothing industry based on Lean management, combining SIPOC, VSM, 5S techniques and a production system to increase profitability in the short term and make it sustainable in time. The model is validated by a case study in a representative company of the sector. The proposed activities were monitored through the study of work indicators, in which the results indicate an increase in productivity by 59% and the fulfillment by 48%.

A Kraljic matrix was used to identify products based on their criticality considering material segmentation, warehouse capacity and times, and ABC segmentation to classify products on each quadrant of the matrix. This project also focuses on defining purchasing and supply strategies in each quadrant of the matrix. This model involves the development of three processes that are related to a new purchasing strategy: economic order quantity, lot-for-lot ordering, and just in time. This new system is based on a more accurate inventory because continuous improvement attracts employees’ attention and engages them in reducing the number of manual notifications made by operators every month. Moreover, after implementing the new procedure for recording inventories, the inventory record was 87% accurate, whereas, in the past, the inventory was not counted and was performed by employees of other areas.

La presente tesis abarca la propuesta de un modelo de gestión de abastecimiento utilizando Supplier Relationship management y PDCA, los mismos que son enfoques logísticos y de mejora continua respectivamente, cuyo objetivo principal es aumentar el nivel de servicio, reducir costos e integrar los procesos a la cadena de abastecimiento. Hoy en día las PYMES tienen que enfrentar numerosos retos, entre ellos, incrementar las ventas diarias, mantener satisfechos a los clientes y aumentar la capacidad de respuesta. En ese sentido, el modelo descrito sirve para administrar eficientemente la cadena de suministro de las PYMES del sector agroindustrial, donde se destaca la importancia de integrar y desarrollar al proveedor a la cadena de suministro del cliente.

The dominance of federal and state contracts by large enterprises reduces the share of contracts small and medium-sized enterprises' (SMEs) business leaders obtain. As of the last census reading in 2016, SMEs received only 23% of contracts. The purpose of this multiple case study was to explore the strategies of 3 small business leaders, operating in south Florida, for obtaining state contracts through public procurement. The thematic findings were in the context of the principal-agent theory as the conceptual framework. The participants answered 10 questions in semistructured interviews and provided organizational procurement documents for review. The methodological triangulation of multiple data sources and data analysis led to the identification of 3 primary themes: business performance, overcoming barriers, and strategic initiatives. Enabling proper business performance protocols for revenue, company reputation, pricing, and compliance benefitted the 3 participants as a strategy for successfully winning state contracts. The participants first identified the barriers they experienced, which included access, bargaining power, funding, and labels. The barriers encountered by the participants became less overwhelming with the implementation of strategic initiatives based on knowledge, relationship building, skilled personnel, and taking action. Findings included the importance of SME business leaders and personnel educating themselves on the public procurement process and building relationships with individuals in the various agencies. Application of the findings may lead to a social change of higher small business employment rates, increased revenue, and improved innovation for business leaders.

This qualitative case study was used to examine the Request for Proposal (RFP) evaluation process used by airports for selecting concessions business operators, including retail and duty-free gift shops, restaurants, newsstands, and public parking. The case consisted of 42 purposefully selected RFPs from 35 airports representing 92% of all U.S. commercial airline passenger traffic compared against guidelines found in Airport Cooperative Research Program (ACRP) Report 54. A problem occurs when evaluation outcomes are challenged because of perceptions of bias, and formal protests and legal claims create delays that disproportionately affect small and minority-owned businesses. The purpose of this study was to compare RFP documents for congruence and influences of concessionaire evaluation ratings. Qualitative data analysis, qualitative content analysis, and interpretive coding were used to explain socioeconomic factors inferred from the documents. Gaps existed in available literature for the effect of airport size, governance type, and evaluator motivation on the RFP process. Study findings showed weighted evaluation criteria inconsistencies with the guidelines, evidence of innate governance system influences, government-operated airport RFP preference of revenue generation measures and socioeconomic attachments, independent authority operated preferences for command and control measures, and potential for the use of standardized core evaluation criteria. By challenging the premise of a bias-free government procurement process, positive social change was achievable through this study's reinforcement of federally qualified small and minority business expansion initiatives promoting open participation and fair competition in concessions opportunities at U.S. commercial passenger airports.

Industrial online-reverse-auctions have become a common procurement strategy used by many firms to reduce the cost of purchased goods and services. The advantages of online-reverse-auctions include significant price reductions, increased purchasing and selling efficiencies, and access to new supply and purchasing markets. Despite these benefits, practitioners and academics alike have raised concerns with respect to the impact of online-reverse-auctions on the buyer-supplier relationship. Previous research suggests that the parameters and characteristics of an online-reverse-auction can influence the perceptions of online-reverse-auction participants. This dissertation investigates this phenomenon by examining how the design of an online-reverse-auction influences the supplier's perception of the buyer-supplier relationship. Specifically, this research considers the effects of online-reverse-auction design in terms of the independent variables of auction control, auction bid visibility, and auction award rules and the dependent variables of supplier commitment to the buyer and supplier trust in the buyer. Using a 2 x 2 x 2 quasi-experimental design and the statistical technique of MANCOVA, this study tests hypotheses related to how different online-reverse-auction design characteristics influence supplier commitment to the buyer and supplier trust in the buyer. The results of the study suggest that the type of online-reverse-auctions buyers utilize can have an impact on supplier perceptions of the buyer supplier relationship. Overall, the result suggest that supplier trust is influenced by the type of auction design buyers utilize, however, supplier commitment is not. Auctions utilizing third party auction providers, partial bid visibility, and post auction negotiations tended to result in higher levels of trust on the part of suppliers. This study makes a contribution to the literature in the following areas. First, this study is one of only a handful of empirical studies examining the effects of online-reverse-auction designs on the buyer-supplier relationship. While a considerable debate exists within the literature concerning the pros and cons of online-reverse-auctions, little empirical work exists. This study makes a contribution by providing insight with respect to how online-reverse-auction designs influence supplier perceptions of the buyer-supplier relationships. Secondly, this analysis considers the buyer-supplier relationship in terms of commitment and trust. Previous studies have largely neglected these constructs despite their prominence in the buyer-supplier relationship literature. Finally, given that the use of online-reverse-auctions seems well entrenched in the purchasing strategies of many buying organizations; this study provides guidance for the design of online-reverse-auctions such that buyers can potentially reduce the negative aspects of the process.

Global supply chains have become increasingly complex and a critical source of competitive advantage, which makes the understanding of how supply chains create and distribute value an essential task. Prior literature on concentration risks has primarily focused on customer concentration and has overlooked the challenges posed by the major upstream supply chain partners. In addition, CEOs with an optimal mix of technical and behavioral abilities can shape the strategic decision-making process to obtain an advantage against the nonfinancial stakeholders. The existing literature has also overlooked the significant role of the CEO in reducing the impact of supplier-base/customer-base concentrations. Utilizing objective supply chain relation data collected from Bloomberg SPLC and Compustat, we map the supplier base and the customer base for each electronic and chemical manufacturing firm publicly listed under S&P1500 for the fiscal year 2017. We then construct objective measures of supplier and customer concentrations and examine their impacts on the focal firm's financial performance measured by Tobin's Q, gross profit margin, and net profit margin. The performance metrics also include the focal firm's payable period (against the supplier-base) and receivable period (against the customer-base). We also collect information related to the CEOs appointed by the focal manufacturing firm, such as gender, age, and tenure from Execucomp, and consequently investigate their impacts on the supplier concentration and the customer concentration. Our empirical analysis shows contradictory results in the context of supplier-base/customer-base concentrations: higher supplier-base concentration is observed to harm the focal firm’s financial performance, but higher customer-base concentration leads to an increase in the focal firm’s profitability. Although CEO characteristics such as tenure and age did not have any notable impact, female CEOs are found to reduce the adversarial impact of supplier-base concentration and are assumed to exercise a voluntary power restraint against the cooperative customer-base.

New Product Development is a key strategy for company performance. Competencies involved in those projects are numerous and varied. Companies increasingly involve their suppliers in codevelopment projects to gather the most relevant knowledge, improve product quality and reduce time to market. Different levels of supplier involvement are defined in literature: white, gray and black box according to their responsibilities. This master thesis focuses on  he collaboration between supplier and customer in the case of New Product Development.  eflecting on existing literature, this master thesis first proposes a new taxonomy of boundary spanning, based on four main areas: knowledge transfer, knowledge translation, knowledge transformation and coordination. Secondly, each area is broken down into collaborative activities, which in turn are linked to the proper Information Technologies (IT). Finally, this typology is successfully confronted to two case studies.
