From quality gurus and TQM to ISO 9001:2015: a review of several quality paths

A revision of several paths for the Quality journey is presented: from Quality Gurus and Total Quality Management (TQM) models to the ISO 9000 International Standards Series. Since ISO 9001:2008 is now in the revision process to the expected ISO 9001:2015 version, an analysis is made of he proposed changes and the underlying reasons and the impacts foreseen on the more than 1.3 Million certified organizations. This revision should be a step towards TQM and reflect the changes of an increasingly complex, demanding and dynamic environment, while assuring that complying organizations are able to provide conformity products and services that satisfy their customers. Major benefits are expected such as less emphasis on documentation and new/reinforced approaches: consideration of Organizational Context and (relevant) Stakeholders, Risk Based thinking and Knowledge Management.

ISO 9001:2015, Uma Oportunidade para o Reajustamento das Empresas no Sector Metalúrgico Metalomecânico

O pretexto da implementação de um Sistema de Gestão da Qualidade numa empresa de produção de fundos copados, constitui pretexto para provocar uma análise mais profunda e fundamentada do tema e objetivo para este projeto. Entender um conceito tão subjetivo como o de qualidade afigura-se como necessidade primária para o início da reflexão. Percorremos em seguida a história do conceito desde a Europa Medieval até à revolução na qualidade que acabaria por acontecer no Japão após a II Guerra Mundial. A qualidade como a entendemos hoje deve-se ainda a contributos de personalidades que identificaram vários métodos que surgiram ao longo do tempo e que foram melhorando o conceito, de entre as quais se referem três: William Deming, Joseph Moses Juran e Philip B. Crosby. Em seguida reflete-se acerca do impacto real da implementação da ISO 9000, recorrendo ao estudo de Olivier Boiral, que fornece uma aproximação bastante real dos benefícios da implementação de sistemas de gestão da qualidade. Ainda no segundo capítulo analisamos a importância do processo de certificação, concluindo que a tarefa extra de uma organização externa certificar o SGQ constitui indubitavelmente uma forma de manter o sistema rigoroso e disciplinado. No terceiro capítulo, “ISO 9001:2008 VERSUS ISO 9001:2015”, analisamos em detalhe as principais alterações da futura norma ISO 9001:2015 relativamente à iISO 9001:2008: introdução do “pensamento baseado no risco”; enfase dado à abordagem por processos; enfase dado à “gestão da mudança”; “gestão do conhecimento”; “direção estratégica”, integrando os sistemas de gestão e da qualidade; a determinação de que todas as normas que integram um sistema de gestão seguirão um novo formato, chamado “high-level structure” como definido no Anexo SL; e enfase ainda dado à consideração do feedback de todos os processos e stakeholders envolvidos. Seguidamente, no capítulo “Apresentação da “Empresa Lda””, apresenta-se a empresa alvo deste caso de estudo, uma indústria metalomecânica que fabrica fundos copados para o mercado nacional e internacional. Analisadas as principais alterações entre a atual e a futura norma, no capítulo “SGQ Proposto Assente na Futura Norma ISO 9001:2015” propõem-se alterações ao sistema já implementado anteriormente com base na aceitação da futura ISO 9001:2015 e alterações que esta prevê. Os processos e procedimentos que representem mais tempo e custo serão 6 identificados, assim como aqueles que poderão ser mais rapidamente adaptados para que o SGQ seja assim otimizado e mais adaptado aos recursos disponíveis. Para esta reflexão e desenvolvimento de uma nova estratégia recorre-se a vários instrumentos: estabelecem-se objetivos, efectua-se a análise SWOT, uma análise FMEA, a Análise de Gestão do Conhecimento e finalmente a Análise das Partes Interessadas. Em conjunto com as propostas de ações referidas nas análises anteriores descrevem-se de seguida as propostas de ação de intervenção nos fluxogramas. Os processos e procedimentos que aqui se destacam são aqueles que se consideram poderem constituir impacto eficaz e que vão ao encontro daquilo que é proposto na nova norma ISO 9001:2015, tendo em conta as principais alterações vistas anteriormente.

Development of an inspection regime for on-site domestic wastewater treatment systems

The overall purpose of this study was to develop a thorough inspection regime for onsite wastewater treatment systems, which is practical and could be implemented on all site conditions across the country. With approximately 450,000 onsite wastewater treatment systems in Ireland a risk based methodology is required for site selection. This type of approach will identify the areas with the highest potential risk to human health and the environment and these sites should be inspected first. In order to gain the required knowledge to develop an inspection regime in-depth and extensive research was earned out. The following areas of pertinent interest were examined and reviewed, history of domestic wastewater treatment, relevant wastewater legislation and guidance documents and potential detrimental impacts. Analysis of a questionnaire from a prior study, which assessed the resources available and the types of inspections currently undertaken by Local authorities was carried out. In addition to the analysis of the questionnaire results, interviews were carried out with several experts involved in the area of domestic wastewater treatment. The interview focussed on twelve key questions which were directed towards the expert’s opinions on the vital aspects of developing an inspection regime. The background research, combined with the questionnaire analysis and information from the interviews provided a solid foundation for the development of an inspection regime. Chapter 8 outlines the inspection regime which has been developed for this study. The inspection regime includes a desktop study, consultation with the homeowners, visual site inspection, non-invasive site tests, and inspection of the treatment systems. The general opinion from the interviews carried out, was that a standardised approach for the inspections was necessary. For this reason an inspection form was produced which provides a standard systematic approach for inspectors to follow. This form is displayed in Appendix 3. The development of a risk based methodology for site selection was discussed and a procedure similar in approach to the Geological Survey of Irelands Groundwater Protection Schemes was proposed. The EPA is currently developing a risk based methodology, but it is not available to the general public yet. However, the EPA provided a copy of a paper outlining the key aspects of their methodology. The methodology will use risk maps which take account of the following parameters: housing density, areas with inadequate soil conditions, risk of water pollution through surface and subsurface pathways. Sites identified with having the highest potential risk to human health and the environment shall be inspected first. Based on the research carried out a number of recommendations were made which are outlined in Chapter 10. The principle conclusion was that, if these systems fail to operate satisfactorily, home owners need to understand that these systems dispose of the effluent to the 'ground' and the effluent becomes part of the hydrological cycle; therefore, they are a potential hazard to the environment and human health. It is the owners, their families and their neighbours who will be at most immediate risk.

Niche conservatism in non-native birds in Europe: niche unfilling rather than niche expansion

Aim Niche conservatism, or the extent to which niches are conserved across space and time, is of special concern for the study of non-native species as it underlies predictions of invasion risk. Based on the occurrence of 28 non-native birds in Europe, we assess to what extent Grinnellian realized niches are conserved during invasion, formulate hypotheses to explain the variation in observed niche changes and test how well species distribution models can predict non-native bird occurrence in Europe. Location Europe. Methods To quantify niche changes, a recent method that applies kernel smoothers to densities of species occurrence in a gridded environmental space was used. This corrects for differences in the availability of environments between study areas and allows discrimination between 'niche expansion' into environments new to the species and 'niche unfilling', whereby the species only partially fills its niche in the invaded range. Predictions of non-native bird distribution in Europe were generated using several distribution modelling techniques. Results Niche overlap between native and non-native bird populations is low, but niche changes are smaller for species having a higher propagule pressure and that were introduced longer ago. Non-native birds in Europe occupy a subset of the environments they inhabit in their native ranges. Niche expansion into novel environments is rare for most species, allowing species distribution models to accurately predict invasion risk. Main conclusions Because of the recent nature of most bird introductions, species occupy only part of the suitable environments available in the invaded range. This signals that apart from purely ecological factors, patterns of niche conservatism may also be contingent on population-specific historical factors. These results also suggest that many claims of niche differences may be due to a partial filling of the native niche in the invaded range and thus do not represent true niche changes.

A Novel Acute Retroviral Syndrome Severity Score Predicts the Key Surrogate Markers for HIV-1 Disease Progression.

OBJECTIVE: Best long-term practice in primary HIV-1 infection (PHI) remains unknown for the individual. A risk-based scoring system associated with surrogate markers of HIV-1 disease progression could be helpful to stratify patients with PHI at highest risk for HIV-1 disease progression. METHODS: We prospectively enrolled 290 individuals with well-documented PHI in the Zurich Primary HIV-1 Infection Study, an open-label, non-randomized, observational, single-center study. Patients could choose to undergo early antiretroviral treatment (eART) and stop it after one year of undetectable viremia, to go on with treatment indefinitely, or to defer treatment. For each patient we calculated an a priori defined "Acute Retroviral Syndrome Severity Score" (ARSSS), consisting of clinical and basic laboratory variables, ranging from zero to ten points. We used linear regression models to assess the association between ARSSS and log baseline viral load (VL), baseline CD4+ cell count, and log viral setpoint (sVL) (i.e. VL measured ≥90 days after infection or treatment interruption). RESULTS: Mean ARSSS was 2.89. CD4+ cell count at baseline was negatively correlated with ARSSS (p = 0.03, n = 289), whereas HIV-RNA levels at baseline showed a strong positive correlation with ARSSS (p<0.001, n = 290). In the regression models, a 1-point increase in the score corresponded to a 0.10 log increase in baseline VL and a CD4+cell count decline of 12/µl, respectively. In patients with PHI and not undergoing eART, higher ARSSS were significantly associated with higher sVL (p = 0.029, n = 64). In contrast, in patients undergoing eART with subsequent structured treatment interruption, no correlation was found between sVL and ARSSS (p = 0.28, n = 40). CONCLUSION: The ARSSS is a simple clinical score that correlates with the best-validated surrogate markers of HIV-1 disease progression. In regions where ART is not universally available and eART is not standard this score may help identifying patients who will profit the most from early antiretroviral therapy.

An Adaptive Field Detection Method For Bridge Scour Monitoring Using Motion-Sensing Radio Transponders (RFIDs), TR-617, 2014

A comprehensive field detection method is proposed that is aimed at developing advanced capability for reliable monitoring, inspection and life estimation of bridge infrastructure. The goal is to utilize Motion-Sensing Radio Transponders (RFIDS) on fully adaptive bridge monitoring to minimize the problems inherent in human inspections of bridges. We developed a novel integrated condition-based maintenance (CBM) framework integrating transformative research in RFID sensors and sensing architecture, for in-situ scour monitoring, state-of-the-art computationally efficient multiscale modeling for scour assessment.

Official Positions for FRAX® clinical regarding falls and frailty: can falls and frailty be used in FRAX®? From Joint Official Positions Development Conference of the International Society for Clinical Densitometry and International Osteoporosis Foundation on FRAX®.

Risk factors for fracture can be purely skeletal, e.g., bone mass, microarchitecture or geometry, or a combination of bone and falls risk related factors such as age and functional status. The remit of this Task Force was to review the evidence and consider if falls should be incorporated into the FRAX® model or, alternatively, to provide guidance to assist clinicians in clinical decision-making for patients with a falls history. It is clear that falls are a risk factor for fracture. Fracture probability may be underestimated by FRAX® in individuals with a history of frequent falls. The substantial evidence that various interventions are effective in reducing falls risk was reviewed. Targeting falls risk reduction strategies towards frail older people at high risk for indoor falls is appropriate. This Task Force believes that further fracture reduction requires measures to reduce falls risk in addition to bone directed therapy. Clinicians should recognize that patients with frequent falls are at higher fracture risk than currently estimated by FRAX® and include this in decision-making. However, quantitative adjustment of the FRAX® estimated risk based on falls history is not currently possible. In the long term, incorporation of falls as a risk factor in the FRAX® model would be ideal.

Kiinteistönhoidon make-or-buy -analyysin valmistelu toimintoperusteisesti Case: Andritz-Ahlstrom Oy

Tutkielmassa kartoitetaan tekijöitä, jotka vaikuttavat yrityksen kiinteistönhoidon make-or-buy –päätöksiin. Tutkielman päätavoitteena on selvittää case –yrityksen kiinteistönhoidon toimintoperusteiset kustannukset. Osatavoitteena testataan toimintoperusteisen kustannuslaskennan soveltuvuutta yrityksen tukitoimintojen kustannuslaskennassa. Tutkielma on tyypiltään laadullinen tutkimus ja tutkimusotteena on käytetty konstruktiivista tutkimusotetta. Tutkimusmetodiltaan työ on case-tutkimus. Tutkielmassa rakennetaan toimintoperusteinen kustannuslaskentamalli, jolla selvitetään case -yrityksen kiinteistönhoidon palveluiden tuottamisesta aiheutuvat kustannukset. Laskentatulosten pohjalta todetaan ne toiminnot, joihin kiinteistönhoidon järjestäminen case -yrityksessä sitoo rahaa ja joihin tulisi kohdistaa kustannusten leikkaamistoimenpiteet. Kiinteistönhoidon toimintoja analysoidaan yksitellen sekä toiminnon toimintoperusteisten kustannusten kautta että etsien tekijöitä, jotka vaikuttavat palvelun itse tekemiseen tai palvelun ostamiseen ulkopuoliselta toimittajalta. Tutkielmassa ei tehdä kannattavuusvertailuja itse tekemisen ja ostopalveluiden välillä.

Cumulative Costs of Caries Prevention and Treatment in Children - with Special Reference to Work Division and Cohort Effect

Lapsen karieshoidon kustannuskertymän muutokset ja karieshoidon toimintakäytäntöjen yhteys kustannuksiin Tutkimuksen tavoitteena oli mitata terveyskeskuksessa hoidettavien lasten karieshoidon kumulatiivisia kustannuksia ja verrata niitä kahden erilaisen toimintatavan välillä. Lisäksi tarkasteltiin lasten hampaiden terveyttä. Tutkimus tehtiin julkisen palvelutuottajan näkökulmasta. Tutkimusaineisto kerättiin Kemin ja Tornion terveyskeskusten suun terveydenhuollon potilaskertomuksista. Kemin kohortit 1980, 1983 ja 1986 (n = 600) ja Tornion kohortit 1980 ja 1992 (n = 400) edustivat perinteistä ja Kemin kohortit 1989, 1992 ja 1995 (n = 600) uutta toimintatapaa työnjaon ja ehkäisyn ajoituksen suhteen. Kohortteja ja kaupunkeja verrattiin hampaiden terveyden (dmft/DMFT = 0 ja dmft ja DMFT keskiarvot 5 ja 12 vuoden iässä) ja voimavarojen käytön suhteen. Panoskäyttö johdettiin käyntimäärien avulla laskennallisen työajan kautta. Kustannuskertymät muodostettiin käyttämällä henkilöstömenoista laskettuja suorittajakohtaisia yksikkökustannuksia. Panoskäytön ja yksikkökustannusten kautta muodostettiin kustannuskertymät. Kustannusten ja terveysvaikutusten suhteita arvioitiin kustannus-vaikuttavuusanalyysissä. Suuhygienistien työpanosta hyödyntävällä varhaisen ehkäisyn toimintamallilla saavutettiin vähäisemmin kustannuksin alle kouluiässä parempi ja kouluiässä yhtä hyvä hammasterveys kuin perinteisellä, enemmän hammaslääkärien työpanokseen perustuvalla tavalla. Karieksen hoitoon liittyvien käyntien määrä oli nuorimmissa syntymävuosikohorteissa pienempi kuin vanhimmissa kohorteissa. Käynnit hammaslääkärissä vähenivät eniten. Toimintatavalla oli merkittävä vaikutus lapsen karieshoidon kokonaiskustannuksiin. Herkkyysanalyysin mukaan karieshoidon kustannukset olivat työnjakoa hyödyntämällä kolmanneksen pienemmät, kuin jos hoidon suorittajana olisi ollut ainoastaan hammaslääkäri-hoitaja työpari. Lasten karieshoidon kustannusvaikuttavuus kohentui molemmissa terveyskeskuksissa nuoremmissa kohorteissa vanhempiin verrattuna. Suun terveydenhuollon potilaskertomuksia olisi hyödynnettävä toiminnan kehittämisessä. Varhaisen ehkäisyn avulla voitaisiin kaikkien suun terveydenhuollon ammattihenkilöiden työpanos kohdentaa kustannustehokkaasti.

Basel 2:n vaikutukset pk-yritysten rahoituspäätöksiin

Maailmantalouden globalisoitumisen myötä riskienhallinan rooli erityisesti rahoitusmarkkinoilla on korostunut entisestään. Pankeille on säädetty vakavaraisuusvaatimuksia, joita noudattamalla pyritään rahoitus-markkinoiden vakauden ja läpinäkyvyyden edistämiseen. Tämän tutkimuksen tarkoituksena on selvittää minkälaisia vaikutuksia pankkien uudella vakavaraisuussäädöksellä, Basel 2, on suomalaisten pk-yritysten rahoituspäätöksiin. Aiheesta ei ole vielä Suomessa tehty vastaavanlaista empiiristä tutkimuksesta. Tämä tutkimus on tehty yhteistyössä Elinkeinoelämän keskusliiton kanssa. Tuloksia analysoitiin erilaisten oletushypoteesien mukaan. Kokonaisuudessaan Basel 2:n odotetaan näkyvän yrityksissä kiristyneinä lainaehtoina. Tulosten mukaan noin joka viides yritys raportoi lainaehtojensa kiristyneen viimeisen kahden vuoden aikana. Vakuuksien vaatimus sekä luoton riskiperusteinen hinnoittelu olivat myös lisääntyneet merkittävästi. Lisäksi tutkimuksessa saatiin myös yllättäviä tuloksia esimerkiksi perheyritysten vaikutusten kohdalla. Tuloksissa on pyritty ottamaan huomioon markkinahäiriön aiheuttamat vaikutukset.

Sarbanes- Oxley – lain vaikutus suomalaisten yhtiöiden tilintarkastukseen

Tutkielmassa tarkastellaan Sarbanes-Oxley -lain Auditing Standard 5:n (AS 5) vaikutusta suomalaisten yhtiöiden tilintarkastukseen. Teoriaosuudessa käsitellään corporate governancea ja tilintarkastusta sen osana, COSO ERM -viitekehystä ja kontrolleja sekä Sarbanes Oxley -lakia. Tutkielman painopisteenä ovat AS 5:n sisältökokonaisuudet: mm. ylhäältä alas- ja riskiperusteinen lähestymistapa sekä turhien tarkastusprosessien poistaminen. Tutkimusaineisto kerättiin vuosina 2007–2009 erilaisista ammattilehdistä ja blogeista sekä haastattelemalla kolmea suurten tilintarkastusyhteisöjen tilintarkastajaa. AS 5 näyttää korostaneen riskiperusteisuutta tilintarkastuksessa sekä tehostaneen tilintarkastusprosessia mm. sallimalla aiempien vuosien tarkastustietojen entistä laajemmin käytön. Näyttää myös siltä, että AS 5 on alentanut tilintarkastuspalkkioita.

Sähkönsiirtoyritysten kunnossapidon taloudellinen malli

Sähkönsiirtoyritysten kunnossapidon taloudellinen malli eli SKUTMA, on sähköverkkoyhtiöille suunniteltu luotettavuuspohjainen kunnossapitomalli, mikä priorisoi ja ajoittaa sähkönjakeluverkon komponenttien huolto- ja investointiajankohdat. Malli hyödyntää dynaamisen optimoinnin algoritmia kustannusminimien löytämiseksi tarkastelujaksolta ja simuloi komponenttien rappeutumasta rappeutumismallin avulla. Tässä diplomityössä on kehitetty kunnossapito-ohjelma SKUTMA-mallin pohjalta, minkä avulla tutkitaan mallin toimivuutta oikeilla johtolähdöillä ja sen hyödyntämistä sähköverkkojen kunnossapidon suunnittelussa. Työssä käydään läpi myös kunnossapitoohjelman laskenta metodiikkaa ja sen ominaisuuksia. Tämän työn lopputuloksena saadaan selkeä kuva mallin toiminnasta, käytettävyydestä ja jatkokehityspotentiaalista.
