There is a need to determine the performance benefits that firms gain from enterprise resource planning (ERP) systems, and the factors that contribute to success. Consequently, the central research problem is:To determine the impact of ERP systems on organisational performance by analysing achieved ERP benefits within the framework of a suitable performance measurement system (PMS), and to investigate the association between critical success factors (CSFs) and ERP benefits.A list of expected ERP benefits and CSFs is compiled. Performance measurement models are evaluated, and one model is designed to evaluate ERP impact. ERP experts refine identified ERP benefits and CSFs using structured interviews. These are built into a questionnaire, and used to survey South African (SA) companies in manufacturing, mining, and power generation.Results indicate that business benefits are realised by companies that implement ERP systems. By building benefits into the performance measurement model, a positive impact on organisational performance is observed. Although a core list of CSFs is identified, and three associations are found between CSFs and ERP benefits, further research is needed. OPSOMMINGDaar bestaan 'n behoefte om die voordeel wat onderneminghulpbronbeplanningstelsels aan ondernemings bied te bepaal en die faktore wat bydra tot die sukses daarvan te ondersoek. Die navorsingsvraag is dus:Om die impak van onderneminghulpbronbeplanningstelsels op die organisatoriese prestasie van ondernemings te ondersoek binne die raamwerk van 'n gepaste prestasiebestuurstelsel, asook die verband tussen kritiese suksesfaktore en onderneminghulpbronbeplanningstelsels.'n Lys van verwagte ondermeninghulpbronbeplanning voordele en kritiese suksesfaktore is saamgestel.Prestasiemeetmodelle is evalueer en een model is ontwerp om onderminghulpbronbeplanning se impak te evalueer. Hieruit word 'n vraelys saamgestel. Die vraelys word dan gerig aan Suid-Afrikaanse ondernemings in die vervaardiging-, mynbou-en kragopwekkingbedryf.Die resultate toon dat besigheidsvoordele realiseer word deur ondernemings wat onderneminghulpbronbeplanningstelsels implementeer. 'n Positiewe impak op organisatoriese prestasie word ervaar deur voordele by die prestasiemeetmodel in te sluit.
Interest in consensus in strategic operations needs to be matched by the ability to measure it accurately. This paper identifies a weakness in current measures of consensus, and designs a new instrument, measuring both before and after, that formulates a strategic plan. Convergence of participants' opinions as an indicator of consensus is proposed and applied, then determined and analysed. The instrument is applied in twelve companies, represented by 27 participating individuals, using a standard manufacturing strategy-setting methodology. Results indicate that convergence (consensus) rather than divergence predominates. Divergence, the opposite of convergence, also becomes important, further expanding the perspective of consensus. OPSOMMINGBelangstelling in konsensus aangaande strategiese bedryfsaktiwiteite moet gepaard gaan met die vermoë om dit akkuraat te kan meet. Hierdie artikel identifiseer tekortkominge in bestaande maatstawwe van konsensus en ontwerp 'n nuwe instrument wat beide voor-en na-metings kan doen sodat 'n strategiese plan geformuleer kan word. Konvergensie van die deelnemers se opinies as 'n indikator van konsensus word voorgehou, toegepas en daarna geanaliseer. Die instrument is toegepas in twaalf maatskappye wat verteenwoordig is deur 27 deelnemende individue waar 'n standaardmetodologie vir die opstel van 'n vervaardigingstrategie gevolg is. Die resultate toon dat konvergensie (konsensus) eerder as divergensie oorheers. Divergensie, die teenoorgestelde van konvergensie, word ook belangrik aangesien dit die perspektief van konsensus uitbrei.
The Toyota Production System (TPS) has been cited as being the pinnacle of continuous improvement approaches in manufacturing organisations, and many models of the TPS are well known. However, some authors question the effectiveness of established approaches, and propose Bateson's theory of learning [1] to be an effective way to explain phenomena like the TPS. This paper investigates the degree to which TPS elements are found in selected South African organisations. It constructs a model of the TPS using Bateson's theory of learning as a framework. The adoption of TPS elements is investigated through multiple qualitative case studies in seven organisations. The analysis follows a clustering and crosscase approach combined with pattern matching. While elements vary in their use, the selected organisations practise the TPS substantially less than the model advocates, with the model being least practised in low volume job/batch manufacturing. Product-process differences and higher levels of the TPS model may clarify peculiar outcomes. OPSOMMINGDie Toyota Vervaardigingstelsel (TPS) word deur sommige beskou as die toppunt van volgehoue-verbetering metodes tans in gebruik deur veral vervaardigingsmaatskappye, en teorieë oor die stelsel is welbekend. Sommige kenners reken egter die huidige verstaan van die TPS skiet tekort in sekere aspekte, en stel Bateson se teorie [1] oor hoe mense leer voor as 'n beter manier om 'n fenomeen soos die TPS te verstaan. Hierdie artikel ondersoek die voorkoms van die basiese aard van die TPS by geselekteerde Suid-Afrikaanse organisasies. Bateson se teorie word as 'n raamwerk gebruik om 'n model van die TPS op te stel. Kwalitatiewe gevallestudies, waaraan sewe organisasies deelneem, word gebruik om data in te samel. Die analise volg 'n groepering en kruisondersoek benadering tesame met patroonontleding om tot 'n gevolgtrekking te kom. Elemente van die model word wisselend toegepas en aansienlik minder as wat die TPS model voorhou, met die minste toepassing gevind in lae volume / lot-vervaardiging omgewings. Interessante uitkomste word moontlik verduidelik deur produk-proses vergelykings asook die toepassing van die hoër vlakke van die TPS model soos opgestel.
This article investigates how supply chains, especially long supply chains, compete in the South African aerospace industry. A multiple case study methodology is employed, involving six selected firms. Semi-structured interviews provide the primary source of data. Multiple case analysis identifies similarities in competitive dimension criteria for supplier-firm and customer-firm units in the supply chain. Results indicate that supplier-firm units compete on the basis of speed, dependability, quality, flexibility, and cost. Customer-firm units compete on the basis of speed, quality, and flexibility. The results also identify focus areas for future research into how long supply chains compete in the South African aerospace industry. OPSOMMINGHierdie artikel ondersoek hoe voorsieningskettings, veral uitgerekte kettings, meeding in die Suid-Afrikaanse lugvaartindustrie. 'n Meervoudige gevallestudie-metodologie is gevolg waartydens ses ondernemings bestudeer is. Semi-gestruktureerde onderhoude was die primêre bron van data. Meervoudige gevalle-analise identifiseer ooreenkomste in die mededingingskriteria vir leweransiers-en kliëntefirmas. Die resultate toon dat leweransiers kompeteer op spoed, betroubaarheid, kwaliteit, aanpasbaarheid en koste. Kliëntefirmas ding mee op grond van spoed, kwaliteit en aanpasbaarheid. Die resultate identifiseer fokusareas vir verdere navorsing op hierdie terrein.
