Supplier Development: Practices and Critical Factors : A Dyadic Multiple-case StudySoleymani Farokh Zadeh, Hoda January 2013 (has links)
Background: As enterprises focus on their core competence, outsourcing other activities other firms can do better, the necessity of managing supplier relationships and upgrading the inter-firm relationships become evident. Supplier development as a potential attempt, tries to fill the gap between ideal criteria and the particular suppliers’ actual capabilities and performance in the supply chain. The buying firms initiate the supplier development efforts in order to increase their abilities to create and deliver a superior value to their own customers. In this respect, it is essential to investigate the practices and story of what the buyer and the supplier do in relation to supplier development and what factors contribute to the success of the program and benefits of the dyad. Furthermore, acknowledgment of difficulties that might bring failure in the SD should be taken into consideration so as to possibly avoid them. The supplier development is widely neglected a dyadic view in literature review. The importance of this study is adding the supplier’s standpoint to the buyer’s view in order to achieve the dyadic perspective associated with the practices, the success factors and the barriers. Purpose: This research aims to identify and describe the practices of supplier development in buyer-supplier dyads. The success factors of the supplier development program and the barriers to the supplier development programs are also investigated based on the buying and supplying firms’ perspectives. The main goal is to contribute to a better understanding of the supplier development from a dyadic standpoint. Method: This study is conducted from an interpretivism standpoint with the use of a deductive approach and qualitative strategy. A holistic multiple-case study of two plastic manufacturing firms as the buyers and their three main suppliers (three dyads) is applied in Iran. The empirical data is gathered via 6 different semi-structured interviews. The empirical evidence is analyzed by using within-case, cross-case and pattern matching analysis. The study considers the ethical issues; harm to participant, informed consents, invasion privacy and deception. The research quality is based upon trustworthiness and authenticity. Result, conclusion: Thanks to within-case analysis which generates the dyadic view with respect to practices, success factors and barriers to supplier development, amazing result is achieved that rarely mentioned by the previous research. A number of conflicting views between the buying firm and the supplier is found due to dyadic investigation which demonstrates the gaps between the buyer and supplier’s perceptions in dyadic relationship. The dyads are simultaneously involved in both direct and indirect supplier development practices. Based on the level of buying firm’s involvement in supplier development activities, the dyads partially follow the degree of sequence from low, moderate to high involvement levels. Each dyad can eliminate or keep the lower level of buyer’s involvement activities when they start the moderate and high level of buyer’s involvement practices. However, the specific position cannot be identified for a particular dyad and the supplier development activities are scattered in all three levels. Based on the dyadic standpoint, the factors that contribute to success of the supplier development program in each dyad can be seen as buyer-, supplier-specific and interface success factors. In this regards, this dyadic multiple-case study confirms the reviewed literature associated with success factors and finds supplier’s top management support and previous supplier development experiences as the additional factors in supplier-specific area that contributes to the successful inter-firm relationship and the supplier development that are not pinpointed by the previous studies. Barriers to the supplier development are factors which hinder the success of the supplier development program. According to the literature review, the barriers could be divided into buyer-, supplier- specific as well as buyer-supplier interface barriers. This study partially confirms the previous studies and reveals some surprising results. One of the most useful findings of the research is that only one barrier in buyer-specific category is verified by one of the dyadic cases. However, in addition to identified barriers, lack of supplier’s top management support and supplier’s indolence are seen as the supplementary supplier-specific barriers to the supplier development. Interestingly, there are other types of barriers that cannot be found in the previous research which is categorized as context barriers. This type includes those kinds of barriers that are originated in the context of relationship in a dyad.

Comparative Analysis of Software Development Practices across Software Organisations : India and SwedenAbheeshta, Putta January 2016 (has links)
Context. System Development Methodologies (SDM’s) have been an area of intensive research in the field of software engineering. Different software organisations adopt different development methodologies and use different development practices. The frequency of usage of development practices and acceptance factors for adoption of development methodology are crucial for software organisations. The factors of acceptance and development practices differ across geographical locations. Many challenges have been presented in the literature with respect to the mismatch of the development practices across organisations while collaborating across organisations in distributed development. There is no considerable amount of research done in context of differences across development practices and acceptance factors for adoption of a particular development methodology. Objectives. The primary objectives of the research are to find out a) differences in (i) practice usage (ii) acceptance factors such as organisational, social and cultural b) explore the reasons for the differences and also investigate consequences of such differences while collaborating, across organisations located in India and Sweden. Methods. A literature review was conducted by searching in scientific databases for identifying common agile and plan-driven development practices and acceptance theories for development methodologies. Survey was conducted across organisations located in India and Sweden to find out the usage frequency of development practices and acceptance factors. Ten interviews were conducted to investigate, reasons for differences and consequences of differences from the software practitioners from organisations located in India and Sweden. Literature evidences were used to support the results collected from interviews. Results. From the survey, organisations in India have adopted a higher frequency of plan driven practices when compared to Sweden and agile practices were adopted at higher frequency in Sweden when compared to India. The number of organisations adopting "pure agile" methodologies have been significantly higher in Sweden. There was significant differences were found across the acceptance factors such as cultural, organisational, image and career factors between India and Sweden. The factors such as cultural, social, human, business and organisational factors are responsible for such differences across development practices and acceptance factors. Challenges related to communication, coordination and control were found due to the differences, while collaborating between Indian and Sweden sites. Conclusions. The study signifies the importance of identifying the frequency of development practices and also the acceptance factors responsible for adoption of development methodologies in the software organisations. The mismatch between these practices will led to various challenges. The study draws insights into various non-technical factors such as cultural, human, organisational, business and social while collaborating between organisations. Variations across these factors will lead to many coordination, communication and control issues. Keywords: Development Practices, Agile Development, Plan Driven Development, Acceptance Factors, Global Software Development. / -

Urbanização e cheias: medidas de controle na fonte. / Urbanization and flood: low impact development practices.Tominaga, Erika Naomi de Souza 24 October 2013 (has links)
A urbanização acelerada das últimas décadas aliada à ocupação desordenada e intensa impermeabilização do solo, têm agravado as cheias nas cidades brasileiras. Na cidade de São Paulo, recentemente, os períodos chuvosos, entre os meses de outubro e março, de 2009-2010 e 2010-2011 foram especialmente relevantes, quando ocorreram precipitações intensas e de longa duração que causaram grandes inundações e alagamentos por toda a cidade. Outro agravante é a continuidade da utilização única e exclusivamente de técnicas clássicas com enfoque higienista para a solução dos problemas de drenagem urbana, como é o caso das canalizações dos córregos e rios. Diante dessa problemática surge uma nova abordagem do tema que envolve o manejo sustentável das águas pluviais por meio da utilização de um conjunto de medidas de controle da fonte, que podem ser integradas aos sistemas de drenagem existentes. Essas medidas se baseiam na retenção e infiltração das águas pluviais e na retenção de poluentes, reduzindo a probabilidade de inundações e contribuindo para a melhoria da qualidade da água dos sistemas hídricos urbanos. O objetivo deste estudo foi avaliar, por meio da modelagem matemática, o efeito que a implantação de medidas controle na fonte pode proporcionar no abatimento dos picos de cheia em áreas urbanas densamente ocupadas. Para tanto foi selecionada a bacia do córrego da Luz localizada no centro da cidade de São Paulo que apresenta altas taxas de impermeabilização do solo. As análises foram feitas com o PCSWMM, que é um sistema de suporte a decisão espacial desenvolvido pela CHI para o SWMM5 da EPA. Foram selecionadas medidas de controle na fonte que possam se adequar em locais onde a disponibilidade de espaço é pequena, como é o caso dos pavimentos permeáveis, telhados verdes e jardins de chuva. Os cenários analisados consideraram a situação atual sem implantação de medidas de controle e a implantação individual e combinada das medidas de controle na fonte. São avaliados eventos de precipitações, considerando diferentes períodos de retorno e durações de chuva e a porcentagem de área impermeável contribuinte para as medidas de controle. Uma análise geral dos resultados da modelagem permite apontar que o amortecimento dos picos de cheia foi verificado em todos os cenários, em maior ou menor intensidade, e o melhor desempenho no abatimento do pico de cheia foi verificado nos cenários que consideraram a implantação de pavimentos permeáveis. Os resultados da modelagem e os baixos custos de implantação dos pavimentos permeáveis sugerem que esta medida, dentre as três analisadas, é a que apresenta melhor custo-benefício. Contudo sabe-se que a implantação de pavimento asfáltico permeável em 100% da área disponível pode não ser viável. Logo a implantação conjunta com outras medidas de controle pode melhorar o desempenho de um sistema de controle de cheias. / The accelerated urban growth in the last decades associated with a disordered occupation and excessive impervious surfaces has worsened the floods in Brazilian cities. In the City of São Paulo, lately, the rainy season between October and March, in 2009-2010 and in 2010-2011, were especially relevant. There were intense and long-lasting rainfalls that caused flooding all over the city. Another aggravating factor is the single and exclusive use of traditional stormwater management methods for solving urban drainage problems, which is the case of stream and river canalizations. When faced with these problems, a new approach that involves the sustainable management of rainwater starts growing. These techniques include a set of low impact development practices that should be incorporated to the existing drainage systems. They are based on the detention and infiltration of stormwater, also the retention of pollutants. They also contribute to decreasing flood probability and to improving water quality of urban water systems. The goal is to evaluate, through a mathematical modeling, the low-impact development practices effect on reducing the peak runoff rates in highly urbanized areas. To this end, a subcatchment located in the center of São Paulo city, called Córrego da Luz, was chosen. This subcatchment has high rates of soil imperviousness. The analysis will be made with the PCSWMM, which is a spatial decision support system for the SWMM5 from EPA. The PCSWMM was developed by CHI. The low-impact development techniques selected for this study are permeable pavements, green roofs and rain gardens. These techniques can be implemented in places where space is no longer available. The scenarios must consider the current situation without the implementation of control measures, the individual and combined implementation of these practices. Various rainfall events were evaluated considering different durations. Also evaluated were the different percentages of impervious areas treated by low-impact development techniques. An overview of modeling results allows stating that the reduction of peak runoff was observed in all the scenarios, at greater or lower intensity. But the best performance was observed in scenarios that considered the implementation of permeable pavements. Modeling results and low-cost implementation of permeable pavements suggest that it is the most cost-effective measure, among the three analyzed. However, it is known that the implementation of permeable pavement in 100% of the available area may not be feasible. Hence, the combined implementation with other low-impact developments might improve the performance of a flood control system.

Analytical Probabilistic Models for Evaluating the Hydrologic Performance of Structural Low Impact Development PracticesZhang, Shouhong 04 April 2015 (has links)
<p>Low Impact Development (LID) practices have been increasingly used to mitigate the adverse impacts of urbanization. Reliable methods are in need to provide hydrologic performance assessment of different types of LID practices. The purpose of this thesis is to develop a set of analytical models which can be used to assist the planning and design of commonly used structural LID practices such as green roofs, rain gardens, bioretention and permeable pavement systems.</p> <p>The analytical LID models are derived on the basis of exponential probability density functions (PDF) of local rainfall characteristics and mathematical representations of the hydraulic and hydrologic processes occurring in association with the operation of LID practices. Exponential PDFs are found to provide good fits to the histograms of rainfall characteristics of five cities located in different climatic zones. The mathematical representations are all physically based and most of the input parameters used in these representations are the same as those required in commonly used numerical models.</p> <p>The overall reliability of the analytical LID models are tested by comparing the results from these analytical models with results determined from long-term continuous simulations, in addition to that the accuracy of the analytical model for green roofs is also verified against observations from a real case study. The long-term rainfall data from the five cities and a variety of LID practice design configurations are used in the comparisons. The relative differences between the results calculated using the analytical LID models and the results determined from corresponding SWMM simulations are all less than 10%.</p> <p>The Howard’s conservative assumption is adopted in the development of the analytical models for rain gardens and permeable pavement systems. This assumption results in conservative estimations of the stormwater management performances of these LID practices. Instead of adopting the Howard’s conservative assumption, an approximate expected value of the surface depression water content of a bioretention system at the end of a random rainfall event [denoted as ] is derived and used in the development of the analytical model for bioretention systems. The use of is proven to be advantageous over the use of the Howard’s conservative assumption.</p> <p>The analytical LID models are comprised of closed-form mathematical expressions. The application of them can be easy and efficient as illustrated in the application examples. For a specific location of interest, with a goodness-of-fit examination of the exponential PDFs to local rainfall data and verification of the accuracy of the analytical LID models, these models can be used as a convenient planning, design, and management tool for LID practices.</p> / Doctor of Philosophy (PhD)

The Impact of Elementary Career Development Practices and Elementary School Counselor Self EfficacySeibert, Michele G. 15 January 2014 (has links)
Career development is becoming a nationwide focus beginning in elementary schools for a variety of reasons. This is particularly true in Virginia as noted by Virginia’s College and Career Readiness Initiative published in September of 2010 by the Virginia Department of Education. Virginia’s Board of Education adopted the Virginia state school counseling standards in January of 2004 that specifically identified career development as an integral part of elementary school counseling (Virginia Board of Education, 2004).
This study was conducted to identify what career development practices K-5 elementary school counselors reportedly conducted in the 2010-2011 school year, the extent counselors believed they were meeting Virginia elementary counseling standards, and if a relationship existed between counselor self-efficacy and specific career development practices. The researcher also measured if a relationship existed between counselor self-efficacy and the total number of career development activities each counselor conducted in the 2010-2011 school year. Virginia public elementary school counselors were emailed and asked to participate in an online survey that was comprised of a portion of The Florida School Counselors Survey 2000 (Osborn & Baggerly, 2004) and The School Counselor Self-efficacy Scale (SCSE) (Bodenhorn & Skaggs, 2005).
Results indicated the activities conducted most often by counselors who reported meeting all state standards were: conducting classroom career exploration, using print materials, and using online career exploration programs. The career development practices showing a significant practical difference in means conducted by counselors with high self-efficacy scores included, conducted classroom career exploration, used online career exploration programs, informed parents of career development school counseling standards, and informed teachers of ways to incorporate career development into the classroom. No relationship was indicated between counselors conducting a certain number of career development practices and self-efficacy scores.
Implications from the results may benefit counselor educators to determine if it is necessary to expand elementary career development instruction and preparation for future elementary school counselors. Future research in this area would be helpful on both the state and national levels to create a detailed list of expectations and means of accountability in meeting both state career development standards and ASCA career development standards. / Ph.

Práticas culturais adotadas por uma empresa familiar visionária para perpetuar a ideologia central estudo de caso da expresso medianeira / Cultural practices adopted by a visionary business to perpetuate the central ideology expresso medianeira : case studyHuppes, Daniela 22 July 2008 (has links)
From studies of Collins and Porras (1995) which show that visionary businesses possess a fundamental central ideology for its perpetuation, the main objective of this work was to analyze the practices of human development and communication of a visionary business, in order to identify cultural elements used to strengthen the central ideology. Thus, the following specific objectives were determined: to examine basic values responsible for the permanent character of the organization in analysis, to verify how values are institutionalized, to investigate the communication system and to analyze the practices of human development of the business. The method adopted was a case study, applied at Expresso Medianeira, a family
business, in a collective transport segment, located in Santa Maria, Rio Grande do Sul. With the employment of interviews, document analysis and non-participant observation; it was possible to evidence that the cultural elements permeate the day-to-day of the organization.
The heroes, rites, rituals, ceremonies and stories are symbolic dimensions which strengthen the values declared by the business and lived by its members. These cultural elements manifest through the practices of communication and human development which are strategically utilized by Expresso Medianeira, such as events, processes of socialization, performance evaluation, and reward and penalty. / A partir dos estudos de Collins e Porras (1995) que mostram que as empresas visionárias possuem uma ideologia central fundamental para sua perpetuação, essa pesquisa buscou
analisar as práticas de desenvolvimento humano e de comunicação de uma empresa visionária, a fim de identificar que elementos culturais são utilizados para reforçar sua
ideologia central. Para tanto, foram traçados os seguintes objetivos específicos: examinar os valores básicos responsáveis pelo caráter permanente da empresa em análise, verificar como os valores são institucionalizados, investigar o sistema de comunicação e analisar as práticas de desenvolvimento humano adotadas. O método adotado foi o estudo de caso, aplicado na Expresso Medianeira, uma empresa familiar, do ramo de transporte coletivo urbano,
localizada em Santa Maria, Rio Grande do Sul. Com o emprego de entrevistas, análise de documentos e observação não participante foi possível constatar que os elementos culturais
permeiam o dia-a-dia da organização. Os heróis, ritos, rituais, cerimônias e estórias são dimensões simbólicas que reforçam os valores declarados pela empresa e vivenciados pelos
seus membros. Esses elementos culturais se manifestam através das práticas de comunicação e de desenvolvimento humano que são estrategicamente utilizadas pela Expresso Medianeira, como os eventos, os processos de socialização, de avaliação de desempenho e de recompensas e punições.
