A estratégia viável é investir no aumento da qualidade e produtividade. O foco desse trabalho é investigar fatores relevantes para mensurar o Return on Investment (ROI) em Melhoria de Processo de Software (MPS). Com o objetivo de propor um framework constituído por fases baseado nos conceitos da ROI Methodology, utilizando indicadores utilizados por David Rico em ROI of SPI e uma seleção de medições utilizadas para MPS. As fases são: Identificação do problema; Diagnóstico detalhado; Estimativa de ROI; Implementação e Encerramento. Para cada fase, baseados no paradigma GQM Goal-Question-Metric foram definidos indicadores de medição para monitorar o FROISPI. As quatro primeiras fases seguem o conceito clássico do PDCA, que para cada solução sugerida de melhoria, analisa seus resultados e se os mesmos forem considerados plenamente satisfatórios, seguirá para a fase de Encerramento, caso contrário o processo cíclico continua até a necessidade de melhoria ser satisfeita. Na fase de Encerramento serão apresentados à alta direção os resultados alcançados com a utilização do FROISPI. O experimento foi executado em três organizações de maturidade bem distintas, mas somente uma organização conseguiu concluir com êxito

Mutual Fund Investment based on Genetic Algorithm

Chen, Chih-shiang 21 October 2011 (has links)
This research proposes a decision and behavior model which tries to approximate the fund trading. The main idea is based on the principle of the publication ¡§Genetic Algorithms for the Investment of the Mutual Fund with Global Trend Indicator¡¨, and four optimization schemes are proposed as well. First, the calculation of GTI is refined to prevent the possible problems caused by the case that all the fund are getting rise, or the opposite. Second, the tolerance is considered to avoid the reduction of profits owing to the increase of rates for transaction which Funds, those near threshold ones, might exchange ranking too often. Third, the concept of Stop-Loss Point is involved to release the fund dynamically instead of oversell. The last, Someone like to investment more profitable with short-term data, but high-risk. Someone like to investment long-term data, therefore, we added (1-£\)History + (£\)Recent to make users could set by themselves. And we also design genetic algorithm to calculate £\ for reference. Under the constraints of three different coefficients of stop-loss and release, the Return of Investment (ROI) is four times than original one(8.98%), which is compared in 2007.

The Impact of BIM/VDC on ROI : Developing a Financial Model for Savings and ROI Calculation of Construction Projects

Salih, Sen January 2012 (has links)
Building Information Modeling (BIM) or Virtual Design and Construction (VDC) recently has been regarded as crucial by the architecture, engineering, and construction (AEC) industry. The use of BIM/VDC represents the creation and use of a three-dimensional (3D) virtual model that amplifies the design, construction, and operation of a building. This technological improvement fundamentally changes the process of how the buildings are designed and constructed. However, the approach to the use of advanced technology in the AEC industry does not seem to be welcomed by the majority of the industry regarding high initial cost of implementation. This study presents data gathered from meetings, interviews and a case study which was a construction project run in Sweden to determine the savings implementing BIM/VDC and to reveal the return on investment (ROI) from a general contractor (GC) perspective. The potential savings to the GC to invest in BIM/VDC were estimated based on the PENG model, measurable cost benefits associated with reduced schedule overruns and reduced change order cost. This thesis confirmed that BIM/VDC results in vast savings and positive impacts on ROI based on the results from the case study which deployed it successfully.

Tidsvinster med automatiserade regressionstester

Ström, Marcus, Kjessler, Oskar January 2022 (has links)
Denna studie undersöker tidsvinsterna med en investeringen av automatiserade regressionstester i förhållande till manuellt genomförande. Syftet med detta är att skapa ett beslutsunderlag av ROI och break-even beräkningar med avsikten att minska osäkerheten ifall investeringen kommer resultera i en tidsvinst under systemets livslängd samt hur stora dessa vinster kan bli. För att undersöka detta har automatiska regressionstester utvecklats, där en mätning av tidsåtgången för detta användes som den investerade tiden. De automatiska testernas tid för genomförandet av studiens testfall jämfördes med den manuella motsvarigheten. Detta har tillsammans med empiriskt material från intervjuer stått som grund för ROI och break-even beräkningar gällande investeringen av automatiska regressionstester. Det empiriska materialet bidrog till beräkningarna med parametrarna testfrekvens, testmängd och livslängd. Till skillnad från tidigare forskning genomför studien beräkningar med flera testfrekvenser, vilket resulterade i att även vid en relativt låg testfrekvens har automatiska regressionstester goda förutsättningar för ett positivt ROI. Vid en medel till hög testfrekvens kunde break-even punkten uppnås inom ett år med möjligheter för stora tidsvinster. Det empiriska materialet har även påvisat att uppstartsfasen, systemtypen, testfallens komplexitet och återanvändning är faktorer som kan påverka tidsvinsterna. / This study examines the time savings of an investment in automated regression tests relative to a manual approach. The purpose of this is to produce an underlay for decision making consisting of ROI and break-even calculations which has the intention of reducing uncertainty in case the investment will result in time savings within the systems life span as well as how big these savings can become. To examine this, automated regression tests have been developed where time spent was measured to be used as the invested time. The time it took for the automated tests to execute the studies test cases were compared with the manual counterpart. This has, together with the empirical material from the interviews, formed the basis for ROI and break-even calculations regarding the investment of automated regression tests. The empirical material contributed to the calculations with parameters for test frequency, test amount and life span. Unlike previous research, this study uses calculations with a higher amount of test frequencies which showed that even with a relatively low test frequency, automated regression tests have good opportunities for a positive ROI. With a medium to high test frequency, the break-even point was reached within one year with possibilities for great time savings. The empirical material has also shown that the start-up phase, system type, test case complexity and reusability are factors that can affect the time savings.

The relationship between corporate social responsibility and firm performance: a study of South African listed companies

Mukoki, Paul Shepherd 06 April 2016 (has links)
A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, Johannesburg in partial fulfilment of the requirements for the degree in Master of Commerce (50% course work) / A growing number of institutional investors that are adopting corporate social responsibility (CSR) philosophy are playing a crucial role in influencing listed companies to adopt and address CSR issues. CSR is defined as “…a concept whereby companies integrate social and environmental concerns in their business operations…” (European Commission, 2010). CSR is now widely accepted as a way of doing business in the contemporary environment. It is evident in companies that are spending large sums of money, time and effort on satisfying various stakeholders’ requirements for responsible behaviour. Despite the growing pressure on companies to become socially responsible, the direct benefits of CSR contribution to firm performance remain questionable. From existing literature the relationship between CSR and firm performance have pointed to mixed results (Gladysek & Chipeta, 2012; Aggarwal, 2013). This study examines the relationship between CSR performance and firm performance using the CSRHub sustainability indexes as proxy for CSR performance. The firm performance measures of firm value (Tobin’s Q) and financial accounting performance (return on assets) were used. Annual data of firms from the Johannesburg Stock Exchange (JSE) from year 2009 to 2012 was analysed using the Multiple Regression Analysis techniques. The study revealed that significant and positive relationship exists between CSR/environmental performance and firm value of listed South African companies. The study concluded that there is no significant relationship between firm performance and the other components of CSR such as community relations, employment relations, and governance. The relatively small sample size of the listed companies, some missing values on the sample data and the shorter time period on the study are the main limitations acknowledged in this report. In the overall, the study provides important insights for understanding the contribution of CSR and its disaggregated components to firm performance.

How mentorship is perceived to contribute to the well-being of an employee in an explosives manufacturing organisation / Hendrik Jacobus Botha

Botha, Hendrik Jacobus January 2014 (has links)
The title of the research is “How mentorship is perceived to contribute to the well-being of an employee in an explosives manufacturing organisation”. This research was conducted within AEL Mining Services, an explosives manufacturing organisation that is part of the AECI group of companies. The object of the research was to gain a better understanding of the association between mentorship and well-being, based on how the experience is perceived by the employee that was either part or not part of such a program, be it formal or informal. During the literature study authors such as Keating (2012:91), Govender and Parumasur (2010:2) and Masango (2011:1) felt very strongly that mentorship begins on the day of birth and continues throughout one‟s entire life where competencies in the mentor role entail understanding self and others, communicating effectively and developing employees and it is clear that great leaders would not have achieved their full potential without effective mentoring. During the literature study it was also found that advantages as well as disadvantage are linked to mentorship, but that the advantages outweigh the disadvantages. Research identifies the need for sustainable development and although a variety of mentorship models exist that are currently used, it is evident that mentorship does have an impact on whoever is subjected to it. The study adopted a quantitative methodology, in which more than one questionnaire was utilised. Mentorship was identified as the independent variable and well-being as the dependent variable. For this study, the respondents were required to disclose geographical information concerning themselves and in addition to this, the Mental Health Continuum and General Health Questionnaire was utilised in order to determine the level of well-being as perceived by the respondents, based on mentorship or the lack thereof. The Statistical Consultation Services of the North-West University determined the statistical methods and procedures for the analyses of the research. Ellis and Steyn (2003:51-53) make it clear that in many cases it is important to know whether a relationship between two variables is practically significant. The research made use of triangulation where Gratton and Jones (2010:121) propose that triangulation can strengthen the validity of research, and is useful as a means to demonstrate trustworthiness in the analysis. Based on the results generated from the statistical analysis, the mentored group has a better overall state of health and psychological well-being than the non-mentored group. The deduction is thus made that with mentorship there is a significant difference in the overall well-being of an employee that was subjected to such a program. Recommendations were made regarding further research that needs to be conducted, in which a mentorship program is tailored for a specific company/organisation within the explosives manufacturing industry, then implemented and the results of it measured over a period of time. / PhD, North-West University, Potchefstroom Campus, 2014

Six Sigma : a framework for successful implementation in South African firms / A.G. Britz

Britz, Albertus Gerhardus January 2008 (has links)
There can be little doubt that Six Sigma is far more than just another novelty concept; in fact, it can be considered as a proven quality philosophy and if applied correctly, ensures a competitive advantage. A rapidly increasing number of firms, from all industries and of all sizes, are now reporting significant savings or returns on their program and training investments, because of the implementation of Six Sigma. This paper investigates the origin, definition, financial benefits and challenges of Six Sigma and its implementation. Certain critical success factors determine the successful implementation of Six Sigma in any firm. Many firms have reported significant benefits as a result of Six Sigma project implementation, though not all are yet success stories. This paper reviews the literature related to the critical success factors for the effective implementation of Six Sigma. This research will provide the useful information for firms, which are willing to implement Six Sigma and help firms avoid the risks during the process of Six Sigma implementation. The primary objective of this exploratory research is to identify the critical success factors required for the successful implementation of Six Sigma. Then, based on the critical success factors identified in literature and the survey, the purpose is to develop and propose an applicable framework for firms to successfully implement Six Sigma. The research is explorative of nature and a survey research design was used with a questionnaire as data-gathering instrument. Descriptive statistics (e.g. means and standard deviations) were used to analyse the data. The results confirmed that the most critical success factors for successful Six Sigma implementation include management commitment, change management, effective communication and alignment. The proposed framework presents six interlinking components of Six Sigma which is dependent on these four critical success factors. Limitations in the research are identified and recommendations for future research are made. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2009.

Investování do nemovitostí / Investment in Real Estate

Kosová, Gabriela January 2019 (has links)
The thesis project analyses current investment opportunities in the real estate market. It investigates the standard sales through real estate agencies and direct sales from developers; the core focus is however on alternative options of buying properties, such as foreclosure auctions, auctions of financial authorities, purchases of agricultural land, etc. The theoretical part of the work examines the ba-sic terminology and ways of buying properties. The practical part uses the findings and evaluates investment opportunities with regard to their risks, the difficulty of the process of acquiring the property and most importantly the return on investment.
