The effects of productivity on profitability: a case study at firm level using an activity-based costing approach

Productivity and profitability are important concepts and measures describing the performance and success of a firm. We know that increase in productivity decreases the costs per unit produced and leads to better profitability. This common knowledge is not, however, enough in the modern business environment. Productivity improvement is one means among others for increasing the profitability of actions. There are many means to increase productivity. The use of these means presupposes operative decisions and these decisions presuppose informationabout the effects of these means. Productivity improvement actions are in general made at floor level with machines, cells, activities and human beings. Profitability is most meaningful at the level of the whole firm. It has been very difficult or even impossible to analyze closely enough the economical aspects of thechanges at floor level with the traditional costing systems. New ideas in accounting have only recently brought in elements which make it possible to considerthese phenomena where they actually happen. The aim of this study is to supportthe selection of objects to productivity improvement, and to develop a method to analyze the effects of the productivity change in an activity on the profitability of a firm. A framework for systemizing the economical management of productivity improvement is developed in this study. This framework is a systematical way with two stages to analyze the effects of productivity improvement actions inan activity on the profitability of a firm. At the first stage of the framework, a simple selection method which is based on the worth, possibility and the necessity of the improvement actions in each activity is presented. This method is called Urgency Analysis. In the second stage it is analyzed how much a certain change of productivity in an activity affects the profitability of a firm. A theoretical calculation model with which it is possible to analyze the effects of a productivity improvement in monetary values is presented. On the basis of this theoretical model a tool is made for the analysis at the firm level. The usefulness of this framework was empirically tested with the data of the profit center of one medium size Finnish firm which operates in metal industry. It is expressedthat the framework provides valuable information about the economical effects of productivity improvement for supporting the management in their decision making.

New evidence on trade liberalization and productivity growth

Although the subject of a large number of studies, the debate on the links between trade reform and productivity growth is still unresolved and most studies at the micro level have not been able to establish a relationship between the two phenomena. Brazil provides a natural experiment to study this issue that is seldom available: it was one of the closest economies in the world until 1988, when trade reform was launched, and intra-industry data are available on an annual basis before, during and after liberalization. Using a panel of industry sectors this paper tests and measures the impact of trade reform on productivity growth. Results confirm the association between the former and the latter and show that the magnitude of the impact of tariff reduction on the growth rates of TFP and output per worker was substantial. Our data reveal large and widespread productivity improvement, so that the estimations in this paper are an indication that liberalization had an important effect on industrial performance in the country. Cross-sectional differences in protection are also investigated.

FDI inflows and outflows, intellectual property rights, and productivity growth

Using panel data of 57 countries during the period of 1995-2012, this study investigates the impact of intellectual property rights (IPR) processes on productivity growth. The IPR processes are decomposed into three stages, innovation process, commercialization process, and IPR protection process. Our results suggest that better IPR protection is directly associated with productivity improvement only in developed economies. In addition, the contribution of IPR processes on growth through foreign direct investment (FDI) appears to be very limited. Only FDI inflows in developed countries which help to create a better innovative capability lead to a higher growth. And in connection with FDI outflows, only IPR protection and commercialization processes are proven to improve productivity in the case of developing countries, particularly when the country acts as the investing country.

Productivity in Knowledge Worker Teams

The use of Information and Communication Technologies in work pro- cesses has not brought the expected productivity improvement. Some studies even suggest that the always-on model decreases productivity. This article proposes work teams as a new unit for knowledge worker productivity analysis in organizations. Organizations? ability to adopt new analysis measures is analyzed in three case studies.

Melhoria e automação de linhas de montagem

Hoje em dia, e com os avanços tecnológicos a surgirem de forma constante, existem novas áreas que têm de ser consideradas com um foco importante por parte de todas as organizações, sendo uma delas a robótica industrial. Motivada em aumentar o seu output, as condições de trabalho para os seus colaboradores, bem como todas as condições de organização da logística interna, a Grohe Portugal, mais especificamente o departamento da montagem, achou relevante fazer um estudo de métodos e tempos, calculando os ganhos potenciais de aumento de output com introdução de robótica nas linhas dos cartuchos. Os objetivos principais seriam então, fazer uma restruturação de todo o layout dessas linhas, tendo como foco automatizar alguma(s) operação(ões), conseguindo assim uma melhoria significativa do output dessas linhas com o menor payback possível. Posto isto, esta dissertação pretende apresentar o trabalho desenvolvido junto da Grohe Portugal, que teve como objetivo fazer os estudos e a automatização de linhas de montagem de cartuchos, bem como melhorar algumas linhas de montagem tendo em conta fatores ergonómicos. Relativamente à automatização da linha dos cartuchos, foi importante estudar todos os seguintes aspetos:  utilização de unidades robóticas;  ergonomia;  ganhos de produtividade;  automatizar ou semi-automatizar operações;  simplificar processos de montagem;  simplificar setups;  solicitar orçamentos;  elaborar caderno de encargos. Para a realização deste projeto, o trabalho desenvolvido foi decomposto em várias etapas, entre as quais se destacam:  análise e estudo dos métodos e sequências de montagem;  levantamento de todos os componentes e operações de montagem até à obtenção do cartucho final;  estudo de tempos de todas essas operações de montagem;  caraterização de um novo layout para as linhas com a introdução de unidades robóticas, tanto quanto possível, mais adequadas;  elaboração de caderno de encargos para ser enviado a empresas, para estas poderem apresentar uma orçamentação, bem como indicar as unidades robóticas mais adequadas para as tarefas pretendidas;  automatização da linha dos cartuchos. Relativamente ao projeto de novas linhas de montagem tendo em conta fatores ergonómicos, de forma a melhorar os sistemas de abastecimento e as condições de trabalho por parte dos operadores, foram postos em prática diferentes passos, nomeadamente:  identificação de todos os processos de montagem realizados pelos operadores na linha a melhorar;  estudo e definição da disposição dos componentes na nova linha, bem como a sua forma de abastecimento;  projeto da nova linha de montagem em 3D com recurso ao software SolidWorks;  realização prática da linha, acompanhando e ajudando a equipa da ferramentaria. O balanço final do trabalho foi bastante positivo, tanto na automatização das linhas de montagem dos cartuchos, em que todo o seu estudo foi alcançado com sucesso, como no melhoramento ergonómico das linhas de montagem, tendo-se alcançado melhorias em alguns índices de qualidade, tempos de abastecimento, organização das linhas, e nas condições de iluminação, resultando essas melhorias numa avaliação positiva por parte dos colaboradores que nelas trabalham todos os dias.

Vanhusten hyvä kotona asuminen: tutkimusta kuntatuottavuudesta, älykodeista ja apuvälinepalveluprosesseista

The purpose of the research was to investigate operational processes related to home care of the elderly as well as use of assistive devices in smart home environments, and operational processes that are generally related to use of assistive devices – from the point of view of productivity improvement. The themes were looked into from the points of view of both the elderly and care personnel. In addition, perspectives of near relatives of the elderly, of the larger service system as well as of companies that provided assistive devices to the smart homes were taken into consideration. In the study of home care processes, 32 customer interviews and 17 employee interviews were carried out. This report contains a summary that is based on a separate report of the home care study. The study of home care was conducted in 2006. The use of technological and mechanical assistive devices and the related operational processes were investigated with the help of the smart home pilot in 2007–2008. The study is described in this report. The smart home pilot was implemented in four different housing service units for elderly people at Lahti, Nastola and Hollola. They were in use during short-term housing periods related to, for instance, end of hospitalisation, holidays of caring relatives and assessment of living and housing conditions. More than 60 different assistive devices and technologies were brought to the smart homes. During the pilot period, experiences of customers and personnel as well as processes related to the use of assistive devices were investigated. The research material consisted of 20 survey questionnaires of personnel and customers, four interviews with customers, five interviews with personnel, feedback survey responses from 14 companies, and other data that were collected, for instance, in orientation events. The research results highlighted the need for tailored services based on an elderly person’s needs and wishes, while taking advantage of innovative and technological solutions. As in the earlier home care study, also assistive device-related operational processes were looked into with the help of concepts of ‘resource focus’, ‘lost motion’ and ‘intermediate landing’. The following were identified as central operational processes in assistive device-related services (regardless of the service provider): (1) acquisition process of technologies and assistive devices as well as of rearrangement and rebuilding works in the home, (2) introduction and orientation process (of the elderly, their relatives and care personnel), (3) information and communication process, and (4) service and monitoring process. In addition, the research focused on design and desirability of assistive devices as well as their costs, such as opportunity costs. The process-based points of view gave new knowledge that may be used in the future to develop service processes and clarify their ownership so that separately managed cross-functional processes could be built with participants from different sectors to operate alongside organisations of elderly care. Development of functionality of assistive device-related services is a societally significant issue.

Pumppujen ja sekoittimien korjausprosessin kehittäminen tietojohtamisen näkökulmasta

Tämän diplomityön tavoitteena oli tehostaa sekä kehittää pumppujen ja sekoittimien korjausprosessin tiedonhallintaa, jotta tietoon liittyvät ongelmat, virheet sekä turhan työn tekeminen vähentyisivät. Samalla tavoitteena oli myös tutkia, minkälaista tietoa prosessissa liikkuu, miten se liikkuu, mihin sitä varastoidaan, kenellä on tietoon pääsy ja sitä kautta havaita tuottavuutta alentavia ongelmakohtia sekä luoda suunnitelmat tulevaisuudessa tehtäville korjaaville toimenpiteille. Tutkimuksen viitekehys sekä pohja rakennettiin liiketoimintaprosessien johtamisen mahdollistaman kehityksen sekä tietojohtamisen tarjoamien työkalujen ympärille pitäen mielessä tiedon merkitys yhtenä yrityksen tärkeimmistä resursseista kilpailuedun kannalta. Tutkimuksen empiirisen osan primäärinen aineisto kerättiin osallistumalla kehitettävään prosessiin sekä havainnoimalla sen etenemistä ja siinä tapahtuvia toimintoja. Sekundäärisenä aineistona hyödynnettiin aikaisemmin luotuja prosessikuvauksia. Korjausprosessin tiedonhallinnan nykytila kyettiin tunnistamaan tutkimalla ja analysoimalla kerättyä aineistoa, jonka perusteella saatiin selville tietoon liittyvät ongelmakohdat. Havaittiin, että ongelmia tuottaa pääasiassa väärästä tiedosta syntyneet virheet, tiedon hidas liikkuminen, tiedon kumuloitumattomuus, rajalliset käyttöoikeudet ja toiminnanohjausjärjestelmän kankeus. Havaittujen ongelmakohtien eliminoimiseksi luotiin suunnitelmat korjaaville toimenpiteille. Myös joitain yksinkertaisempia toimenpiteitä kyettiin jo tekemään tutkimuksen aikana. Tutkimuksesta saadut tulokset olivat hyviä, sillä suunnitelmat korjaavista toimenpiteistä tulevat lisäämään korjausprosessin tehokkuutta sekä tuottavuutta vähentämällä turhan työn tekemistä sekä parantamalla sen tiedonhallintaa. Tulevaisuudessa prosessiin sisältyvä tieto liikkuu nopeammin, virheet vähentyvät, oikean tiedon hyödynnettävyys kasvaa ja toiminnanohjausjärjestelmä tukee ja mahdollistaa tehokkaammin prosessiin liittyvää tiedonhallintaa kasvattaen yrityksen kilpailukykyä suhteessa saman toimialan kilpailijoihin.

Modifioidun MAG-kaarihitsausprosessin hyödyntäminen railotilavuuden pienentämisessä mekanisoidussa orbitaalihitsauksessa.

Länsimaisen työn hinta luo jatkuvan paineen hitsauksen tuottavuuden parantamiseen. MIG/MAG-hitsauksen tuottavuutta voidaan parantaa tehostamalla hitsausprosessia, vähentämällä hitsien lukumäärää ja pienentämällä hitsiaineen tarvetta. Eri virtalähdevalmistajat tuovat markkinoille hitsausprosesseja hitsauksen tehostamiseen, joilla pystytään korvata vähemmän tuottavia hitsaustyövaiheita. Hitsien lukumäärän vähentäminen on rakenteen suunnitteluun liittyvä tekijä ja hitsiaineen tarpeen pienentäminen voidaan toteuttaa railogeometrian muutoksilla tai tuotteen sopivalla suunnittelulla. Diplomityössä on tutkittu 30 mm paksujen S355 rakenneteräsputkien hitsauksen tuottavuuden kasvattamista käyttäen nykyaikaisia modifioituja kaarihitsausprosesseja ja railotilavuutta pienentämällä. Työssä vertailtiin 30o ja 60o railokulmalla tehtyjä liitoksia. Railogeometrian muutoksen lisäksi diplomityössä vertailtiin eri menetelmien tehokkuutta putken pohjapalon hitsauksessa.

The use of simulation for forecasting the number of docks necessary in an expedition department

The simulation is a very powerful tool to develop more efficient systems, hence it is been widely used with the goal of productivity improvement. Its results, if compared with other methods, are not always optimum; however, if the experiment is rightly elaborated, its results will represent the real situation, enabling its use with a good level of reliability. This work used the simulation (through the ProModel (R) software) in order to study, understand, model and improve the expenditure system of an enterprise, with a premise of keeping the production-delivery flow considering quick, controlled and reliable conditions.

Light energy management in peach: utilization, photoprotection , photodamage and recovery. Maximizing light absorption in orchard is not always the best solution

The relation between the intercepted light and orchard productivity was considered linear, although this dependence seems to be more subordinate to planting system rather than light intensity. At whole plant level not always the increase of irradiance determines productivity improvement. One of the reasons can be the plant intrinsic un-efficiency in using energy. Generally in full light only the 5 – 10% of the total incoming energy is allocated to net photosynthesis. Therefore preserving or improving this efficiency becomes pivotal for scientist and fruit growers. Even tough a conspicuous energy amount is reflected or transmitted, plants can not avoid to absorb photons in excess. The chlorophyll over-excitation promotes the reactive species production increasing the photoinhibition risks. The dangerous consequences of photoinhibition forced plants to evolve a complex and multilevel machine able to dissipate the energy excess quenching heat (Non Photochemical Quenching), moving electrons (water-water cycle , cyclic transport around PSI, glutathione-ascorbate cycle and photorespiration) and scavenging the generated reactive species. The price plants must pay for this equipment is the use of CO2 and reducing power with a consequent decrease of the photosynthetic efficiency, both because some photons are not used for carboxylation and an effective CO2 and reducing power loss occurs. Net photosynthesis increases with light until the saturation point, additional PPFD doesn’t improve carboxylation but it rises the efficiency of the alternative pathways in energy dissipation but also ROS production and photoinhibition risks. The wide photo-protective apparatus, although is not able to cope with the excessive incoming energy, therefore photodamage occurs. Each event increasing the photon pressure and/or decreasing the efficiency of the described photo-protective mechanisms (i.e. thermal stress, water and nutritional deficiency) can emphasize the photoinhibition. Likely in nature a small amount of not damaged photosystems is found because of the effective, efficient and energy consuming recovery system. Since the damaged PSII is quickly repaired with energy expense, it would be interesting to investigate how much PSII recovery costs to plant productivity. This PhD. dissertation purposes to improve the knowledge about the several strategies accomplished for managing the incoming energy and the light excess implication on photo-damage in peach. The thesis is organized in three scientific units. In the first section a new rapid, non-intrusive, whole tissue and universal technique for functional PSII determination was implemented and validated on different kinds of plants as C3 and C4 species, woody and herbaceous plants, wild type and Chlorophyll b-less mutant and monocot and dicot plants. In the second unit, using a “singular” experimental orchard named “Asymmetric orchard”, the relation between light environment and photosynthetic performance, water use and photoinhibition was investigated in peach at whole plant level, furthermore the effect of photon pressure variation on energy management was considered on single leaf. In the third section the quenching analysis method suggested by Kornyeyev and Hendrickson (2007) was validate on peach. Afterwards it was applied in the field where the influence of moderate light and water reduction on peach photosynthetic performances, water requirements, energy management and photoinhibition was studied. Using solar energy as fuel for life plant is intrinsically suicidal since the high constant photodamage risk. This dissertation would try to highlight the complex relation existing between plant, in particular peach, and light analysing the principal strategies plants developed to manage the incoming light for deriving the maximal benefits as possible minimizing the risks. In the first instance the new method proposed for functional PSII determination based on P700 redox kinetics seems to be a valid, non intrusive, universal and field-applicable technique, even because it is able to measure in deep the whole leaf tissue rather than the first leaf layers as fluorescence. Fluorescence Fv/Fm parameter gives a good estimate of functional PSII but only when data obtained by ad-axial and ab-axial leaf surface are averaged. In addition to this method the energy quenching analysis proposed by Kornyeyev and Hendrickson (2007), combined with the photosynthesis model proposed by von Caemmerer (2000) is a forceful tool to analyse and study, even in the field, the relation between plant and environmental factors such as water, temperature but first of all light. “Asymmetric” training system is a good way to study light energy, photosynthetic performance and water use relations in the field. At whole plant level net carboxylation increases with PPFD reaching a saturating point. Light excess rather than improve photosynthesis may emphasize water and thermal stress leading to stomatal limitation. Furthermore too much light does not promote net carboxylation improvement but PSII damage, in fact in the most light exposed plants about 50-60% of the total PSII is inactivated. At single leaf level, net carboxylation increases till saturation point (1000 – 1200 μmolm-2s-1) and light excess is dissipated by non photochemical quenching and non net carboxylative transports. The latter follows a quite similar pattern of Pn/PPFD curve reaching the saturation point at almost the same photon flux density. At middle-low irradiance NPQ seems to be lumen pH limited because the incoming photon pressure is not enough to generate the optimum lumen pH for violaxanthin de-epoxidase (VDE) full activation. Peach leaves try to cope with the light excess increasing the non net carboxylative transports. While PPFD rises the xanthophyll cycle is more and more activated and the rate of non net carboxylative transports is reduced. Some of these alternative transports, such as the water-water cycle, the cyclic transport around the PSI and the glutathione-ascorbate cycle are able to generate additional H+ in lumen in order to support the VDE activation when light can be limiting. Moreover the alternative transports seems to be involved as an important dissipative way when high temperature and sub-optimal conductance emphasize the photoinhibition risks. In peach, a moderate water and light reduction does not determine net carboxylation decrease but, diminishing the incoming light and the environmental evapo-transpiration request, stomatal conductance decreases, improving water use efficiency. Therefore lowering light intensity till not limiting levels, water could be saved not compromising net photosynthesis. The quenching analysis is able to partition absorbed energy in the several utilization, photoprotection and photo-oxidation pathways. When recovery is permitted only few PSII remained un-repaired, although more net PSII damage is recorded in plants placed in full light. Even in this experiment, in over saturating light the main dissipation pathway is the non photochemical quenching; at middle-low irradiance it seems to be pH limited and other transports, such as photorespiration and alternative transports, are used to support photoprotection and to contribute for creating the optimal trans-thylakoidal ΔpH for violaxanthin de-epoxidase. These alternative pathways become the main quenching mechanisms at very low light environment. Another aspect pointed out by this study is the role of NPQ as dissipative pathway when conductance becomes severely limiting. The evidence that in nature a small amount of damaged PSII is seen indicates the presence of an effective and efficient recovery mechanism that masks the real photodamage occurring during the day. At single leaf level, when repair is not allowed leaves in full light are two fold more photoinhibited than the shaded ones. Therefore light in excess of the photosynthetic optima does not promote net carboxylation but increases water loss and PSII damage. The more is photoinhibition the more must be the photosystems to be repaired and consequently the energy and dry matter to allocate in this essential activity. Since above the saturation point net photosynthesis is constant while photoinhibition increases it would be interesting to investigate how photodamage costs in terms of tree productivity. An other aspect of pivotal importance to be further widened is the combined influence of light and other environmental parameters, like water status, temperature and nutrition on peach light, water and phtosyntate management.

A Neglected Aspect of Business: Human and Social Capital in the Sri Lankan Tea Plantations

This paper examines idiosyncrasies of tea plantation culture and politics in relation to Sri Lankan national and popular cultural typologies, with special reference to female tea plantation workers. Tea production in Sri Lanka is heavily based on manual labour, and it is the largest industry that provides accommodation for employees and their families. In this paper, it is argued that politico-cultural production relations have dominated labour productivity in tea plantations. Ways in which female workers have been marginalized, through patriarchal politics, ethnicity, religion, education, elitism, and employment are explained. This culture of the plantation community operates negatively with respect to the management agenda. It is also argued that social capital development in tea plantations is important not only for productivity improvement, but also for reasons of political and social obligation for the nation, because migrant plantation workers have been working and living in plantations over 150 years.

Enhancing performance through the introduction of customer orientation into the building components industry

Purpose: This paper aims to describe an investigation into how company performance can be improved by integrating internal and external customers and technology. The approach was developed, implemented and evaluated in the operations of the building components industry. The research was carried out in the precast concrete division of a Singapore company. Design/methodology/ approach: For the purpose of undertaking the investigation an exploratory case study approach was used. This was divided into conceptual and action research stages. The action research was also used to implement the changes in the company. Questionnaire surveys were carried out among company employees and external customers to assess the effect of these changes. Results of the investigation were derived using content and statistical analysis. Triangulation between three sources was used for validating the data. Findings: The exploratory case study strategy resulted in rich research data, which provided evidence of the changes taking place and integration happening, leading to improved performance. The action research approach proved a powerful tool where the uncertainty of outcomes makes it near impossible to make accurate forecasts. Another output of the research was the development of an "integrated customer orientation" (ICO) model. Research limitations/implications: The research in this paper used a single site action research investigation so should be interpreted within the specific company and industry context. There are implications for theory and practice in a number of areas of production and marketing as well as contributions to understanding about productivity improvement and organisational development. The investigation also fulfils the dual objectives of action research by contributing to both knowledge and practice. Originality/value: The paper describes a unique approach towards improving productivity, quality and service through the use of action research to implement changes, as well as providing the research evidence to evaluate both the process of implementation and results achieved. © Emerald Group Publishing Limited.
