Abstract in English, Afrikaans and Sesotho / The study was inspired by the global phenomenon of failure rates of outsourcing ventures; yet, the outsourcing value proposition of 3PL providers is promising and potentially lucrative. The approach of the outsourcing venture was thus investigated, specifically how to align and integrate outsourcing parameters appropriately at the inception of the outsourcing venture in order to attain the benefits brought about by the outsourcing decision over the projected life of the outsourcing venture. To this effect, a strategic decision-making model, with the objective of ascertaining optimal alignment and integration was developed. The model comprises a dualistic development followed by a methodological process path to operationalise the strategic decision-making model. A services continuum (development one) is established, which is a permutation matrix that classifies four aspects of importance (service type, category of 3PL provider, strategic alignment and investment), in order to align the aspects optimally and enable appropriate model application. The services continuum is a conglomeration of nine models:  a capabilities matrix for 3PL provider services;  a framework for evaluating the supply chain role of 3PL providers;  a mathematical model;  a supplier selection and evaluation process;  a presentation of the Hayes–Wheelwright framework;  an outsourcing variables differentiated model;  four categories of the 3PL providers model;  an estimated path model; and  a process integration via survey data collection model. The services continuum was extended for utilisation with risk management practices, and an outsourcing risk matrix (development two) was established. The enablement of the outsource risk matrix is an element review, consisting of three categories: collaboration and integrated planning systems; performance measurement; and broad-based black economic empowerment. The strategic decision-making methodology process path was developed as having three phases, which operationalise the strategic decision-making model. The research was primarily focussed on literature reviews, with the models classified according to the services continuum. To a lesser extent, the research focussed on primary data, which served as model application input specifically for application requirements related to Sasol. The study established a universally applicable strategic decision-making model, as well as the application of the model for Sasol’s outbound (final packaged product) supply chain. / Thuto e ile ya kgothaletswa ke tshebetso ya lefatshe mabapi le maemo a ho hloleha ha ho nyaolwa/ntshuwa ha diprojeke kgwebong; leha ho le jwalo, tlhahiso ya boleng ba ditshebeletso tsa 3PL e a tshepisa ebile e ka ba le hlahiso ya tjhelete e ngata.

Die benadering wat die uitkontrakteringonderneming volg, is derhalwe ondersoek en in die besonder hoe om die uitkontrakteringparameters by die aanvang van die uitkontrakteringonderneming toepaslik in lyn te stel en te integreer om die voordele te benut van die uitkontrakteringsbesluit oor die geprojekteerde lewe van die uitkontrakteringsonderneming. ’n Strategiesebesluitnemingsmodel wat ten doel het om optimale inlynstelling en integrasie te verseker, is dus ontwikkel. Die model bestaan uit ’n dualistiese ontwikkeling, gevolg deur ’n metodologiese prosesbaan om die strategiese besluitnemingsmodel te operasionaliseer. ’n Dienstekontinuum (ontwikkeling een) is op die been gebring, wat ’n permutasiematriks is wat vier aspekte van belangrikheid (dienssoort, kategorie van die 3PL-verskaffer, strategiese inlynstelling en investering) klassifiseer, ten einde die aspekte optimaal in lyn te stel en toepaslike modeltoepassing moontlik te maak. Die dienstekontinuum bestaan uit ’n versameling van nege modelle:  ’n bekwaamheidsmatriks vir 3PL-diensverskafferdienste;  ’n raamwerk om die voorsieningskettingsrol van 3PL-verskaffers te evalueer;  ’n wiskundige model;  ’n verskafferseleksie en evalueringsproses;  ’n aanbieding van die Hayes-Wheelwright-raamwerk;  ’n uitkontrakteringsveranderlike-gedifferensieerde model;  vier kategorieë van die 3PL-verskaffersmodel;  ’n geraamde baanmodel; en  prosesintegrasie deur middel van ’n ondersoekdata-insamelingsmodel. Die dienstekontinuum is uitgebrei vir gebruik by risikobestuurspraktyke en ’n uitkontrakteringrisikomatriks (ontwikkeling twee) is op die been gebring. Die bemagtiging van die uitkontrakteringsrisikomatriks is ’n elementhersiening, wat uit drie kategorieë bestaan: samewerkings- en geïntegreerdebeplanningstelsels; prestasiemeting; en breë swart ekonomiese bemagtiging. Die strategiese besluitnemingsmetodologieprosesbaan is met drie fases ontwikkel, wat die strategiese besluitnemingsmodel operasionaliseer. Die navorsing het hoofsaaklik op literatuuroorsigte gefokus, met die modelle wat volgens die dienstekontinuum geklassifiseer is. Die navorsing het in ’n mindere mata op die primêre data gekonsentreer, wat as die modeltoepassingsinset gedien het, in die besonder vir die toepassingsvereistes wat op Sasol betrekking het. Die studie het ’n universele, toepaslike strategiesebesluitnemingsmodel daargestel, asook die aanwending van die model op Sasol se uitgaande voorsieningsketting (finaal verpakte produk). / Business Management / D.
