An overview of the new tax return form and tax system

Ferreira, Petrus Hendrik (Petri) 18 February 2009 (has links)
During May 2007 it was announced that individual taxpayers would receive simplified tax return forms, will not need to do any more calculations and will no longer need to attach supporting documentation for the 2007 year of assessment. It was also announced that the tax system would be changed, making the turn around times for the assessment of tax returns faster. The primary objective of this research was to determine what effect the new tax return form, as well as the new tax system, would have on the tax practitioner submitting their client’s return. It was considered impractical to compare this study to other studies done. It was therefore decided that a questionnaire would be sent out. After considering all the research performed, it could be concluded that the new tax return form, as well as the new tax filing system, was welcomed by the taxpayer and the tax practitioner, and was a definite improvement, although some implementation problems were encountered.

3D-skanning för kvalitetsarbete i produktionsprocessen för krafttransformatorer : Kartläggning av möjligheter för potentiella processförbättringar hos Hitachi ABB Power Grids / 3D-scanning for quality management in the production process of power transformers

Niroozad, Ellika, Dellerer, Josefine January 2021 (has links)
Hitachi ABB Power Grids is a world leading manufacturer of power transformers, operating on an increasingly competitive market. With the advancements in digitalization and electrification, the production of power transformers has been subject of higher demands, both in terms of product quality and production efficiency. To stay ahead of market rivals, constant development of the business and its production processes is necessary, which has been enabled by increased access to innovative technical solutions. Novel appliances and areas of development has been investigated, of which 3D-scanning is one of the promising technologies that has proven useful in the manufacturing industry.  The purpose of this study has been to map the production process of power transformer manufacturing at Hitachi ABB Power Grids, with the intention of identifying potential areas for use of 3D-scanning technology in quality management. By analyzing each individual production segment, the study has sought to answer to where in the production system that 3D-scanning technology can be beneficial, what type of improvements it can contribute with, and what risks and limitations that using the technology might entail.  The results were obtained by analyzing empirical data, collected through both qualitative and quantitative methods. Interviews with employees and on-site observations has been the main sources of data, together with documentation and statistics from the company’s own data bases.  Central factors that the analysis was built upon are the registered costs of failure and reported quality defects, combined with the appropriateness of 3D-scanning technology in each segment regarding the practical usability, advantage in time, economic profitability, and the feasibility of implementation in the production system. A value assessment was made of the device’s potential, leading to identifying improvements in transparency, traceability, and efficiency. Some of the discussed drawbacks were limited visual access, faulty handling of the equipment, and excessive reliance on the technology. / Hitachi ABB Power Grids är en världsledande tillverkare av krafttransformatorer, agerandes på en alltmer konkurrensbenägen marknad. Med digitaliseringens och elektrifieringens framfart ställs högre krav på produktionen av krafttransformatorer, både gällande produktkvalitet och produktionseffektivitet. För att bibehålla en ledande position krävs därför ständig utveckling av verksamheten och dess processer, vilket bland annat möjliggjorts av den ökade tillgången till innovativa tekniska lösningar. Nya verktyg och förbättringsområden undersöks, varpå en av de uppmärksammade teknikerna är 3D-skanning, vilket visat sig användbart inom tillverkningsindustrin.  Syftet med studien har varit att kartlägga processen för krafttransformatortillverkning hos fallstudieföretaget Hitachi ABB Power Grids, med avsikt att identifiera möjligheterna kring användning av 3D-skanningsteknik i kvalitetsarbetet. Genom att undersöka varje individuellt delmoment i produktionsprocessen har studien sökt besvara var i produktionssystemet som 3D-skanningstekniken kan medföra förbättringar, vilken typ av förbättringar som kan åstadkommas, samt de risker och begränsningar som användning av tekniken eventuellt kan medföra.  Resultaten erhölls genom analys av empiriska data som samlats in genom både kvalitativa och kvantitativa metoder. Intervjuer med personal och observationer på anläggningen har utgjort de huvudsakliga källorna till information, tillsammans med dokumentation och statistik från företagets interna databaser.  Centrala faktorer som analysen har byggt på är produktionens registrerade felkostnader och rapporterade kvalitetsfel, i kombination med 3D-skanningsteknikens lämplighet för respektive avsnitt gällande praktisk användbarhet, tidsmässig fördel, ekonomisk lönsamhet och implementerbarhet i produktionssystemet. En värdering gjordes därefter av teknikens potential, och förbättringar i form av transparens, spårbarhet och effektivitet kunde identifieras. Några av de brister som uppmärksammades var begränsad visuell åtkomst, felaktig manövrering av utrustningen och överdriven tillförlitlighet till tekniken.
