Strukturer och Preferenser inom Konsultmarknaden : En utforskande studie av upphandlingsprocessen för tjänstemannamässig arbetskraft inom tillverkning och logistik / Organizational Structures and Preferences within the Consultancy Industry : An explorative study of the procurement process for engineering services within manufacturing and logistics

Maglica, Daniel January 2017 (has links)
Studiens övergripande syfte är att öka förståelse och förutsättningarna för att studera affärsmöjligheter. Studien har bedrivits induktivt och utgår ifrån 48 stycken intervjuer med verksamhetsspecifika beslutsfattare inom upphandlingsprocessen. Beslutsfattarna är spridda över 11 svenska branscher. Resultatet visar på en stor variation med avseende på upphandlingsmängd för respondentverksamheterna, där en högsta upphandlingsmängd var 110 heltidsanställda konsulter per år och en minsta mängd var 0. Median mängden för de verksamheter som ingick i urvalsgruppen var 3 heltidsanställda konsulter per år. Vidare identifierades 10 stycken konkurrensprioriteringar för urvalsgruppen. 3 konkurrensprioriteringar var exklusiva för den grupp som tillämpade en centraliserad upphandlingsmodell och 3 var exklusiva för den grupp som tillämpade en decentraliserad upphandlingsmodell. Korrelationer mellan leverantörspreferenser med avseende på mängden aktivt bidragande leverantörer och upphandlingsmängder identifierades även. Studien har bidragit med en holistisk bilateral modell som beskriver affärsutbytet mellanen konsultverksamhet och en upphandlande verksamhet. Modellen underlättar vidare studier på så sätt att bakomliggande mekanismer för affärsmöjligheter blir lättare att studera rent systematiskt. Modellen som konstruerats kan användas som ramverk för att bedöma alternativa affärsutbyten. Genom att jämföra relativa värden och preferenser kan olika situationer bedömas för att avgöra vilket alternativ som innebär störst sannolikhet för god affärsmöjlighet. / The primary objective of the study is to increase the knowledge and conditions for studying business opportunities. The study has been conducted inductively and utilizes 48 interviews with firm specific decision-makers within the procurement process. The decision-makers are active in 11 swedish industries. The results show great variation with regards to the procurement volumes for the participating firms, where the largest volume is 110 full-time-equivalent consults per year and smallest is 0. The median value for the sample firms where 3 full-time-equivalent consults per year. 10 factors for driving competition where also identified for the sample group. 3 factors where exclusive to the firms that utilized a centralized procurement model and 3 factors where exclusive to the firms that utilized a decentralized procurement model. Correlations beteen preferences with regards to the amount of active suppliers and procurement volumes were also identified. This study has developed an holistic bilateral model, from the findings, that describes the business trade between a consultancy firm and a procuring firm.

Crescimento e uso de nitrogênio e fósforo de quatro gramíneas nativas do Rio Grande do Sul / Growth and nitrogen and phosphous uses of four native grasses of Rio Grande do Sul state

Oliveira, Leandro Bittencourt de 25 March 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This thesis has the aim to evaluate growth of native grasses of natural grasslands Rio Grande do Sul state: Axonopus affinis, Paspalum notatum, Andropogon lateralis e Aristida laevis belonging to plant functional types A, B, C and D, respectively, in response to increasing N and P in soil. For this, the four grasses were grown in greenhouse with different N and P soil availability. The results were presented in two articles: the first evaluated species responses to increase N and P soil availability and relationships with functional traits and with tissue nitrogen concentration. The second article describes species response to increasing soil P availability besides P chemical fractions accumulated on plant tissue and acid phosphatase activity on leaves. All species respond to increase soil N and P availability but it was evidenced that resources capture species presented shorter time responses than conservation species. Independent of soil nutrients availability conditions where species were grown, the grass P. notatum showed the greater N and P use efficiency. The higher potential of relative response to increase N plus P and P availability was found for the grass A. affinis, which has leaf traits of resources capture species. For this, it was suggested that resources capture species have greater potential response to fertilization in relation to resources conservation species. / Esta tese tem o objetivo de avaliar o crescimento das gramíneas nativas das pastagens naturais do Rio Grande do Sul: Axonopus affinis, Paspalum notatum, Andropogon lateralis e Aristida laevis representantes dos tipos funcionais de plantas A e B de captura de recursos, e C e D de conservação de recursos, respectivamente, em reposta ao aumento na disponibilidade de nitrogênio e de fósforo no solo. Para isso, as quatro espécies foram cultivadas em casa de vegetação com diferentes condições de disponibilidade de P e N no solo. Os resultados foram apresentados em dois artigos: O primeiro avaliou a resposta das espécies à disponibilidade de N e P e as relações com atributos funcionais e com as concentrações de nitrogênio no tecido. O segundo artigo trata da capacidade das plantas em responder ao aumento da disponibilidade de P no solo além das frações químicas de acúmulo de P no tecido e da atividade da fosfatase ácida nas folhas. Nos dois artigos, as espécies responderam em massa tanto ao aumento da disponibilidade de N e de P quanto só de P. Porém no primeiro artigo, ficou evidenciado que a resposta foi identificada em um período mais curto para as espécies com características de captura de recursos em relação às de conservação de recursos. Independente das condições de disponibilidade de nutrientes onde as espécies foram cultivadas, a gramínea P. notatum demonstrou a maior eficiência de utilização tanto de N quando de P. O maior potencial de resposta relativo ao aumento da disponibilidade de N e P e de P foi encontrado para a gramínea A. affinis, a qual possui atributos foliares de captura de recursos. Assim, como esperado as espécies de captura de recursos têm maior potencial de resposta a adubação em relação às espécies de conservação de recursos.
