Productivity trends in the Thai manufacturing sector : the pre- and post-crisis evidence relating to the 1997 economic crisis

Arunsawadiwong, Suwannee January 2007 (has links)
The principal aim of this thesis is to examine the validity of the claim that low productivity led to a decline in Thailand’s competitiveness, and hence, to the 1997 economic crisis. For a decade from 1985 to 1995, Thailand was one of the world’s fastest-growing economies with an average real annual GDP growth of 8.4 percent. However, such growth was criticized as being simply the result of large inward investment and rapid accumulation of capital, leading to very little productivity growth, and therefore, being unsustainable in the long run. Worse still, the later surges of capital inflows came in mainly as speculative stashes, instead of as foreign direct investments in production and businesses. Hence, as predicted, the boom finally came to a sudden end in 1997. The economic growth statistics recorded severe contraction, financial market collapsed, the currency was battered, domestic demand slumped, severe excess capacity was experienced, employment deteriorated, personal and corporate income diminished, inflation and the cost of living mounted, and finally, poverty surged. This thesis utilizes a stochastic production frontier approach to verify the claim that low productivity lessened Thailand’s competitiveness. This approach, unlike the standard econometric approach, allows the existence of technical inefficiency in the production process. It also, unlike other non-parametric approaches, recognizes that such inefficiency can sometimes occur as a result of external factors that are out of the firms’ direct control, such as statistical errors and random shocks. The period covered in this thesis is from 1990 to 2002. This is divided into 2 sub-periods, i.e. the pre-crisis period (1990 – 1996) and the post-crisis period (1997 – 2002). The estimation results indicate a structural shift in the Thai manufacturing sector, from being labour intensive in the pre-crisis period to being capital intensive in the post-crisis period. The productivity level also improved post-crisis, as compared to the pre-crisis level, and is shown to follow an increasing trend. The low productive investment level in the pre-crisis period is identified as having led to the decline in the manufacturing sector’s efficiency. The thesis concludes that this low productivity level did indeed lead to the decline in Thailand’s competitiveness, and hence, to the decline of export growth, which was at that time the main source of Thailand’s economic growth; in turn, playing an important role in precipitating the 1997 economic crisis.

No. of bitstreams: 1 Thiago Antonio Souza.pdf: 1549573 bytes, checksum: 50bb2fe3750913e23e67747ffad33743 (MD5) Previous issue date: 2015-12-23 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / CNPQ – Conselho Nacional de Desenvolvimento Científico e Tecnológico / Hospitais brasileiros tipicamente convivem com um desnivelamento entre capacidade e demanda. Os subsistemas público e privado são incapazes de coordenar situações de falta e excesso de capacidade identificados, de forma concomitante, em suas respectivas estruturas. Custos tornam-se um elemento focal em ambos os casos, quer visando qualidade e segurança quer visando incremento de capacidade, enfocando áreas chave do serviço hospitalar: serviços cirúrgicos, de internação, de emergência e de diagnóstico. O Lean Healthcare, neste contexto, se torna uma filosofia possível para a mudança organizacional dos processos hospitalares visando o incremento de sua eficiência. Este estudo discute a aplicação de conceitos do Lean Healthcare em serviços cirúrgicos, com base em evidências coletadas de três estudos realizados integradamente em um hospital universitário de grande porte, pertencente ao subsistema de saúde público brasileiro. O primeiro estudo enfoca a análise de eficiência do centro cirúrgico, propondo e aplicando o indicador Operating Room Effectiveness (ORE). O segundo, analisa e propõe formas de nivelar a produção (Heijunka) de cirurgias de diferentes demandas competindo pelo mesmo centro cirúrgico, em um contexto de capacidade inferior à demanda. O terceiro estudo desenvolve o conceito de Planejamento, Programação e Controle do Fluxo de Pacientes (PPCFP), com vistas ao planejamento integrado de consultas, cirurgias, pré-operatórios e aquisição de materiais. A aplicação dos modelos conceituais propostos revela potenciais vantagens, ainda a serem estudadas em amplitude e longitude como alternativa para outras organizações do setor. Como resultados locais, além do aporte de conceitos de Engenharia de Produção aplicada ao contexto de saúde, foram identificados: ganho operacional médio de 12% de eficiência nas salas de cirurgia; redução em 40% do tempo médio de espera para cirurgias eletivas; redução média de filas para consultas em 50%; melhor planejamento e controle de eficiência e produção; e economia de cerca de R$ 5.000.000,00 resultante dos três casos. / Brazilian hospitals typically work with a depression between capacity and demand. The public and private subsystems are unable to coordinate situations of shortage and excess capacity identified in their respective structures, concomitantly. Costs become a focal element in both cases, aiming to quality and safety or to increase capacity, focusing on key areas of hospital service: surgical services, admission, emergency and diagnostic. In this context, Lean Healthcare becomes an attractive philosophy for organizational change of hospital processes aiming at increasing its efficiency. This study discusses the application of Lean Healthcare concepts in surgical services, based on evidence collected from three studies integrally in a large University Hospital, part of the Brazilian public health subsystem. The first study focuses on the operating room efficiency analysis, proposing and applying the indicator Operating Room Effectiveness (ORE). The second study analyzes and proposes alternatives to level the production of surgeries (Heijunka) of different brands, competing for the same operating room, at a low capacity context. The third study develops the concept of Planning, Programming and Control of Patient Flow (PPCPF), to establish integrated planning consultations, surgeries, preoperative and acquisition of materials. The application of the proposed conceptual models reveals potential advantages, yet to be studied in amplitude and longitude as an alternative to other industry organizations. As local gains, in addition to the approximation of Industrial Engineering concepts to the health context, it have been identified: 12% increase in the surgical center’s average efficiency; 40% reduction in the average waiting time for elective surgery; 50% reduction in the number of queued consultations; better planning and control efficiency and production; and savings of about R$ 5,000,000.00 resulting from the three cases.

碳排放管制對臺灣工業部門生產效率及汙染減量成本之分析 / Analysis of production efficiency and pollution abatement cost of Taiwan's industrial sector under CO2 regulation

蒲嵩杰, Pu, Song Jie Unknown Date (has links)
全球暖化已成為大多數國家近幾年所關心的議題。雖然臺灣政府於2010年5月所核定的「國家節能減碳總計畫」之中,儘管減量目標及原則業已確立,但未充分探討各別產業的面臨碳排放管制時所造成的影響,因此,臺灣各產業或次部門究竟應承擔多大的減量責任仍是混沌不明。 為了更清楚瞭解碳排放管制對於臺灣工業部門之各產業的影響,本文以方向性距離函數,估算工業部門中14個產業367家上市櫃、興櫃和公開發行公司於2005年至2010年,在不同電力消費所產生的CO2之責任歸屬情況下之生產效率及汙染減量成本,以反映各產業於管制下的機會成本,便於鎖定某些產業或公司,來賦予減量責任。結果發現,各產業在實施碳排放管制後的效率水準,會高於未實施碳排放管制時的效率水準,且各產業的平均總汙染減量成本與每噸二氧化碳減量成本相差甚大。而臺灣尚未通過相關法規以規範各產業二氧化碳排放水準,若各產業節能技術或政府相關配套政策未改善,倉促實施碳排放管制,除了對管制對象的產生影響外,也可能間接衝擊未管制對象。政府除了加強輔導各種產業從事節能技術外,也需要適當的公布各產業各公司的各種汙染排放量資訊,以供各界研究碳排放管制或其他汙染排放管制對社會的影響。 / Global warming has become the topic of most countries which concerns things in recent years. Government sets up CO2 reduction objectives and principle in “General National Plan for Energy Saving and Carbon Reduction” in 2010, but the plan doesn’t probe effect of CO2 regulation which different industries. Therefore, it is unknown that different industries should be responsible for the abatement of CO2. In order to clearly understand effect of CO2 regulation for Taiwan industrial sector, this paper use directional distance function to estimate production efficiency and pollution abatement cost of 367 public companies in 14 industries in industrial sector from 2005 to 2010, and to reflect different industries’ opportunity cost under CO2 regulation. Production efficiency of different industries after the implementation of CO2 regulation will be higher than before the implementation of CO2 regulation. On the other hand, different industries have a variety of average pollution abatement cost and pollution abatement cost of CO2 per ton. However, Taiwan has not yet adopted the environment laws to set up industrial CO2 emission level, if the government hurriedly implemented CO2 regulation for Taiwan industrial sector, may be indirectly influence other sectors. Hence, the government should not only urge that industries must be engaged in energy-saving technologies, but also announce companies’ various pollution emission information which provides research institutes to analyze effect of social welfare under CO2 regulation.

Efektivnost produkce vybraných konvenčních a ekologických farem v západních Čechách / Efficiency of production of selected conventional and organic enterprises in west Bohemia region

KECSEIOVÁ, Klára January 2011 (has links)
The aim of the work is to analyse the production efficiency of conventional and organic farms in the Western Bohemia. Based on the data of questionnaire investigation in 2009 I selected four farms from the Pilsen Region. Evaluative criteria were as follows: the total area under cultivation, farming system (conventional or organic), type of arable crops (especially wheat, oat, potatoes). The data were extracted from terrain investigation, telephone conversations, interview with farmers, yearbook of organic farming, situational review and forecast balance of Czech Statistical Office and Ministry of Agriculture. Supporting data were extracted from ÚZEI database. Crop yields, the costs of crops and selling price in recent 10 years were investigated. From the results it can be concluded, that crop yields in organic farming are lower than crop yields in conventional farming. The yields of wheat growing in organic farming are 40 % lower than in conventional farming. The yields of potatoes growing in organic farming are 40 % lower than in conventional farming and the yields of oat growing in organic farming are 30 % lower than in conventional farming. Production efficiency of chosen crops in organic farming is comparable to conventional farming due to higher redemption price and lower costs. In some organic farms the growing of chosen crops is even more profitable than in conventional farms. Structure of costs in organic farming is the most differential component comparable to conventional farming. It is because of different spending of fertilization and crop management practice.

<b>Using Predictive Analytics to Reduce Small Business Cost Estimation Error</b>

Diana H Solt (17222431) 19 October 2023 (has links)
<p dir="ltr">Small and medium enterprises generally employ the use of custom developed quoting programs to bid on goods and services. Custom bid programs (e.g., Microsoft Excel) are used to capture the company-specific costs of production. The inputs of variable costs, such as machine rate and scrap rate, are critical to get correct (Brassington & Pettitt, 2013); however, companies often rely on educated guesses and industry expertise to quote packaging products to end-users. Due to the guesswork involved there can be a financial difference between the quoted costs and actual costs. This variance is often the cause of significant lost dollars. Price, if not determined correctly, could negatively impact both the company’s and the product’s profitability (Helna, 2020). Predictive analytics can be used to support quoting activities by providing a future value based on previous job performance. The purpose of the present study is to identify whether predictive analytics can be used to predict machine rate and scrap rate to give more accuracy to quoting estimation.</p>

Το "παράδοξο της ενέργειας" στην ελληνική βιομηχανία : έκταση, υιοθέτηση τεχνολογιών εξοικονόμησης ενέργειας και αντιρρύπανσης και επιδράσεις στην απόδοση, αποτελεσματικότητα και παραγωγικότητα

Κουνετάς, Κωνσταντίνος 13 April 2009 (has links)
Το πρόβλημα της κλιματικής αλλαγής αποτελεί έναν από τα κυριότερα σημεία έντονου ενδιαφέροντος για τις περισσότερες χώρες. Μάλιστα, τα επόμενα χρόνια αναμένεται να δοθεί μεγαλύτερη προσοχή στην ανάπτυξη πολιτικών που θα μειώνουν τις εκπομπές ρυπογόνων αέριων ρύπων. Η εξοικονόμηση ενέργειας, ως μέτρο πολιτικής, θα συνεχίσει να αποτελεί μια σημαντική στρατηγική ανάπτυξης για την οικονομία της χώρας μας, μια και συνδέεται σε σημαντικό βαθμό, με την κατανάλωση ενέργειας όπως και με την μείωση των εκπομπών αερίων ρύπων. Επιπλέον, συντονισμένες προσπάθειες τόσο από την Ευρωπαϊκή Ένωση όσο και από άλλους οργανισμούς (IEA, OECD) θέτουν σε βασικό άξονα προτεραιότητας την μείωση της κατανάλωσης ενέργειας, την χρησιμοποίηση εναλλακτικών μορφών και ανανεώσιμων πηγών και την μείωση των ρυπογόνων εκπομπών ιδιαίτερα στον βιομηχανικό κλάδο. Στα πλαίσια της παρούσας διατριβής αναλύονται θέματα που σχετίζονται με την υιοθέτηση τεχνολογιών εξοικονόμησης ενέργειας από Βιομηχανικές επιχειρήσεις. Κεντρικό στοιχείο αυτής της προσέγγισης είναι το “Παράδοξο της Ενεργειακής Αποδοτικότητας”. Τρία συγκεκριμένα θέματα εξετάζονται σε αυτή την κατεύθυνση. Πρώτον, η διερεύνηση των παραγόντων που οδηγούν στην εμφάνιση του “παραδόξου της ενεργειακής αποτελεσματικότητας” και συγκεκριμένα αν οι αποφάσεις των επιχειρήσεων για υιοθέτηση τέτοιων τεχνολογιών συνυπολογίζουν το στοιχείο της αποδοτικότητας των επενδεδυμένων κεφαλαίων. Δεύτερον, και με δεδομένο ότι στα αποτελέσματα του προηγούμενου σταδίου ανάλυσης αναδεικνύουν την σημαντικότητα του παράγοντα της πληροφορίας, αναπτύσσεται μια εκτενής προσέγγιση που αφορά τόσο το περιεχόμενο όσο και τον ρόλο του παράγοντα της πληροφορίας στην διαδικασία υιοθέτησης ΤΕΕ. Τρίτο, διερευνάται η επίδραση της υιοθέτησης των ΤΕΕ στην παραγωγική αποτελεσματικότητα και παραγωγικότητα των βιομηχανικών επιχειρήσεων. Για τις ανάγκες της ανάλυσης αυτών των θεμάτων αναπτύσσονται δύο επιμέρους μικροοικονομικά υποδείγματα και μια μέθοδος μέτρησης της παραγωγικότητας σε ετερογενής τεχνολογίες. Το πρώτο μικροοικονομικό υπόδειγμα διερευνά την διαδικασία λήψης επενδυτικών αποφάσεων σε ΤΕΕ υπό το πρίσμα της συσχέτισης της επενδυτικής επιλογής με την κερδοφορία, σε πλαίσιο μερικής παρατηρησιμότητας. Το δεύτερο μικροοικονομικό υπόδειγμα επανατοποθετεί την έννοια της πληροφορίας και διερευνά τους παράγοντες που προσδιορίζουν το επίπεδο πληροφόρησης της επιχείρησης για ΤΕΕ. Τέλος για την μέτρηση της επίδρασης των ΤΕΕ στην παραγωγική αποτελεσματικότητα και παραγωγικότητα αναπτύσσεται μια μέθοδος που λαμβάνει ρητά υπόψη της την τεχνολογική ετερογένεια. Η διερεύνηση των τριών αυτών ζητημάτων βασίζεται στην ανάλυση εμπειρικών δεδομένων που αφορούν επιχειρήσεις οι οποίες ενέταξαν στην παραγωγική τους διαδικασία τεχνολογίες εξοικονόμησης ενέργειας στην περίοδο 1990-2004. Οι επενδύσεις αυτές επιδοτήθηκαν κυρίως στα πλαίσια του Β’ και Γ’ Κοινοτικού Πλαισίου Στήριξης. Τα δεδομένα συλλέχθηκαν με την μέθοδο των προσωπικών συνεντεύξεων (ερωτηματολόγια). Συμπληρωματικά δεδομένα αντλήθηκαν από την βάση δεδομένων της ICAP. / The improvement for energy efficiency is generally viewed as an important option to reduce greenhouse gas emissions and environmental damage caused by other pollutants (e.g. NOX,SOX). Moreover, is clearly interwoven with the exploitation of new and innovative technologies through the production process and its consequent paradox, the so called “energy efficiency paradox”. This paradox has recently attracted the interest of researchers and organizations (IEA,OECD) in an attempt to bring to light the source of it, the causalities between the adoption of energy efficient technology (EET) and the behaviour of firms . Three research questions have been examined in the specific Phd Thesis. Our first main research question were examined by formulating and testing the following hypothesis: the decision of the firms to adopt or not EET, is correlated to their profitability. Our second research project develops in two stages. The first stage aims at examining the factors influencing retrieval of information concerning EETs by manufacturing firms, while at the second stage we distinguish between readily available and emerging energy efficiency technologies and examine the factors affecting information acquisition for each one of these two broad sets of technologies. Finally, in order to disentangle firm’s heterogeneity we developed a methodological framework to calculate total factor productivity and its components differences arising from EETs adoption. Our first research question examines the energy efficiency paradox demonstrated in Greek manufacturing firms through a partial observability approach. Maximum likelihood estimates that arise from an incidental truncation model reveal that the adoption of the energy saving technologies is indeed strongly correlated to the returns of assets that are required in order to undertake the corresponding investments. The source of the energy efficiency paradox lies within a wide range of factors. Policy schemes that aim to increase the adoption rate of energy saving technologies within the field of manufacturing are significantly affected by differences in the size of firms. Finally, mixed policies seem to be more effective than polices that are only capital subsidy or regulation oriented. Answering the second research question, we aim to redefine the notion of awareness regarding the adoption of EETs. In a second stage we explore the crucial factors that affect the information level of EET adopters, distinguishing between epidemic and emerging technologies information. Our empirical findings reveal that the main factor that exerts positive influence on the level of information acquired by the firms may be encompassed in a set of variables that reflect what may be called a “business culture” regarding the EET Finally, we examined the impact of EETs adoption to Greek manufacturing firms operating under heterogeneous technology sets and we measured the components of total factor productivity (TFP) and its components arising from scale and technological differences. In order to examine our research questions we formulate a unique database. Our database came to light from the necessity of the Greek government to conserve energy in manufacturing and to reduce dangerous emissions in order to meet the criteria of the Kyoto Protocol. An extensive questionnaire was addressed to the 298 firms across the country that adopt EETs that have been subsidized from (i) the Support Frameworks for Regional and Industrial Development, (ii) the Energy Operational Program (OPE), which was part of the second European Union Support Framework (1994-2000) and (iii) the Operational Program ‘Competitiveness’, which is part of the third European Union Support Framework (2000-2006). Finally, 161 of them agreed to be interviewed on the basis of the questionnaire. Face to face interviews took place in the first six months of 2004. Additional data derived from ICAP financial database.

Impact of human dimensions on smallholder farming in the Eastern Cape Province of South Africa

Kibirige, Douglas January 2013 (has links)
Considering the backward and forward linkages, the agro-industrial sector contributes about 12 percent of South Africa‘s GDP, and employs approximately 8.5 million people. In the Eastern Cape Province, the sector contributes about 1.9 percent of the Provincial GDP, and over 3 million people derive their livelihoods from subsistence smallholder farming. Despite its importance, agricultural productivity has stagnated for several years across the Eastern Cape rural communities. There have been several attempts by the government to improve the agricultural productivity on smallholder farms since the end of apartheid, especially through the establishment of small-scale irrigation schemes, subsidization of farm inputs, and provision of credit facilities and enacting a number of land reform policies. In spite of the government support, most rural communities like Qamata and Tyefu are still faced with high levels of poverty affecting 76 percent and 91 percent of the population, respectively. This research evaluated the current smallholders‘ production efficiency, and the link between smallholder farmers‘ human dimensions (entrepreneurial spirit and positive psychological capital, goals and social capital, and other efficiency related variables) with production efficiency and household commercialisation index/level. The study used participatory approaches for site selection, sample selection and data collection. The analysis was based on both information from informal interviews and formal primary data collection. The Data Envelopment Analysis and Stochastic Production Frontier techniques were used to determine the relative efficiencies of individual farmers and to identify the major factors that influence the efficiency of production. Overall, 158 farmers were interviewed both at Qamata and Tyefu irrigation schemes. Descriptive statistics of this study indicated that most of the farmers were men with an average age of 61 years, and mean household size of 4 persons with the household head having at least obtained some primary school education. Farming is the major source of livelihood for smallholders with an average income of R4527.49 per crop season. Smallholders use improved seeds, fertilizers and tractor for ploughing with less use of pesticides and herbicides. Although smallholder irrigators generate more gross margins from maize and cabbage enterprises, generally both categories of farmers exhibited a low average household commercialization index for maize and cabbage at 0.41 and 0.22, respectively. Both Data Envelopment Analysis and Stochastic Production Frontier results indicate that farmers are about 98 percent technically efficient in maize and cabbage enterprises, respectively. However, farmers were allocatively inefficient as they were under-utilizing seed and pesticides while over-utilizing inorganic fertilizers. Factors that are positively associated with technical efficiency in maize production included household size, farming experience, off-farm income, use of agro-chemical; gross margins and commercialisation level of maize output. Determinants of technical efficiency in cabbage enterprise included farming experience, amount of land owned, use of agro-chemicals, group membership and gross margins accrued to cabbage sales. Farmers‘ human dimensions that could be more positively and significantly associated with production, efficiency and household commercialisation level included risk taking (hope), innovativeness (confidence) and optimism for entrepreneurial/positive psychological capital. Farmers‘ goals included self-esteem and independence, and only external social capital which were identified to be more positively and significantly associated with farmers‘ production efficiency and commercialization level. The transition from homestead subsistence to commercial oriented small-scale irrigation farming is inevitable since smallholder irrigators earn more incomes from maize and cabbage and are relatively food secure. However, the key policy options that must be considered to address inefficiencies and improved commercialization level to aid the transition include: agricultural policies geared toward attracting youth in farming, improved quality of extension services, speeding up the land reform process, and formation of cooperatives and participatory policy formulation that takes full cognizance of the farmers‘ human dimensions. Since farmers‘ human dimensions as defined in the literature and this study are not things that are amenable to direct policy intervention, they can only be modified indirectly through policy actions that affect their determinants. This means that a number of the demographic and socio-economic characteristics such as age, sex and education level of household head, farming experience, size of land owned, crop incomes, source of water for irrigation and location of the irrigation scheme that govern the way people perceive reality and respond to them must be the focus of concerted policy actions over the medium to long term.

Effektivisering av badrumsproduktion i en industrialiserad bostadsfabrik : En jämförelse och rekommendation av Lean-effektivisering och inköp av prefabricerade badrumsgolv- och moduler / Streamlining the bathroom production in an industrialized housing factory : A comparison and recommendation of Lean efficiency and purchase of prefabricated bathroom floors- and modules

Kuna, Robert, Bidros, David January 2018 (has links)
Syfte: Att mäta och kartlägga produktionen i en industrialiserad bostadsfabrik samt mäta effektiviteten av dess badrumstillverkning. Den erhållna informationen används vidare som grund för effektiviseringsförslag presenterade för fabriksledningen. Lösningsförslagen är fördefinierade som ”Förbättring av befintlig produktion med hjälp av Lean”, ”Produktion med förtillverkat badrumsgolv” och ”Produktion med förtillverkade badrumsmoduler”. Metod: Mätmetoden som användes vid fabriken är en frekvensstudie (WSM), anpassad efter fallstudiens behov. Mätteknikern går med jämnt tidsintervall till arbetsstationer och antecknar vilken aktivitet som pågår i samma sekund. Efter flera tusen upprepningar skapas en genomsnittlig aktivitetsbild över fabrikens badrumsproduktion. Vidare bearbetas informationen för att erhålla visuella grafer där problem lättare kan identifieras. När problemen fastställts kan lösningsförslagen tas fram och presenteras.  Resultat: Genom att implementera förtillverkade badrumsgolv- eller modul går det att korta badrummens ledtid samt öka hela fabrikens produktionskapacitet. Vidare eliminerar dessa lösningsförslag även kompetenskrävande arbetsmoment, vilket underlättar personalersättning vid exempelvis sjukdom.  Implikationer: De i studien framkomna resultaten antyder att företag lidande av växtvärk har stora möjligheter att omstrukturera och avlasta sin produktion, på så vis att en högre produktionskapacitet erhålls. I detta fall kan produktionskapaciteten utökas på tre olika sätt med olika effektivitetsgrad. Fallstudien kan dock inte svara på exakt i vilken grad effektivitet kan uppnås utan dessa lösningsförslag bör simuleras för att kunna svara på detta. Potential för vidare forskning finns där fallstudien undersöker hur dessa lösningsförslag påverkar fabrikens helhet. Begränsningar: Storleken och komplexiteten i den beaktade fabriksstrukturen begränsade fallstudien från att analysera fabrikens helhet. Avgränsningar behövde göras vid badrumsproduktionen och produktionen av vissa element i badrummen behövde försummas för att författarna rimligen skulle kunna klara av arbetet. / Purpose: To measure and map out the production of an industrialized housing factory, in addition to measure the effectiveness of its bathroom production. The gathered information is then used as foundation for the efficiency improvement proposal presented for the board of directors. The efficiency improvement proposals are predefined as “Improvement of existing production using Lean”, “Production with prefabricated bathroom floors” and “Production with prefabricated bathroom modules”. Method: The measurement method used at the factory was a frequency study called Work Sampling Method (WSM), adjusted after the case study’s needs. The measurement technician goes with regular intervals to workstations and notes the activity happening in that same moment. After several thousand recurrences, an average activity image can be derived from the data depicting the bathroom production. Furthermore, the data is processed to obtain visual graphs where problems become more distinguishable. When the problems are identified, solutions and propositions can be developed and presented. Findings: By implementing prefabricated bathroom floors- or modules the factory can reduce its production time and thereby increase the factories production capacity. Furthermore, the propositions and solutions eliminate competence-required operations within the factory. Thereby facilitates the staff replacement.. Implications: The study shows that companies suffering from growing pain have considerable facilities to restructure and relieve its production, in such a way that a higher production capacity is obtained. The production capacity in this case can be expanded by three different methods with various degrees of efficiency. The case study can however not determine the exact degree of efficiency, to obtain these the propositions should be simulated. Further potential research should be done on how the case studies propositions affect the whole of the factory. Limitations: The size and complexity of the observed factory structure limited the case study from analyzing the whole of the factory. Delimitations had to be done at the bathroom production and the production of certain elements involved in the bathroom production had to be neglected.
