Customers’ satisfaction is a decisive factor in the development process of business which has also an effective impact on contributing a country's GDP. Private banks have been emerged over the time in developing countries where customers’ satisfaction is the driven force of banking industry investigated in Bangladesh. In this study a conventional American Customer Satisfaction Index model has been used over Bangladesh to compare overall performance of banking industry. Customers’ satisfaction in Bangladesh has been measured from the different angle of customers’ perception based on their portfolio. This research has been designed on a quantitative approach followed by survey research method. Questionnaire was administered to collect data through objective list as well as physical interaction with the respondents from different locations in the capital city of Bangladesh named Dhaka. Collected data had been analyzed applying Partial Latent Square (PLS) software program. The study outcomes showed that the perceived quality is the main determinant factor on customer satisfaction towards banks in Bangladesh. It also revealed that significant relationship exists between customers’ satisfaction and customers’ loyalty. The revised model in 2016 represents the benchmark scores of customers’ satisfaction in Bangladesh lagged behind consecutively 18 and 13 scores than that of USA and Taiwan. Considering the study results, we summed the quality of service leads to satisfied customers in turns towards customers loyalty. Banks also can get competitive advantage by evaluating all classes of customers equally through providing superior services to them.

This study investigates the effect of National American Customer Satisfaction Index (NACSI) to aggregate consumer spending at different stage of business cycle. In this paper we use the data from The National Bureau of Economic Research (NBER) to determine the recession term ,and we use EGARCH model to catch the asymmetric performance of aggregate consumer spending at different stage of business cycle. In this study we found that when the economic is not in recession period, improvement in aggregate customer satisfaction have a positive impact on future changes in aggregate discretionary consumer spending. The growth in financial obligations ratio have a negative impact on future changes in aggregate discretionary consumer spending at whole business cycle. The growth in financial obligations ratio also attenuate the positive impact from customer satisfaction, and the effect become more strong in recession period.

I dagens samhälle är det allt viktigare för företag att behålla sina existerande kunder då konkurrensen blir allt hårdare. Detta medför att företag försöker vidta åtgärder för att vårda relationer med sina kunder. Detta problem är även högst relevant inom IT-branschen. Inom IT-branschen är det vanligt att arbeta agilt i IT-projekt. Vår samarbetspartner har sett ett ökat behov av att mäta servicekvalitet på ett återkommande sätt inom IT-projekt, detta för att mäta relevanta variabler som sträcker sig utanför kravspecifikationen. För att mäta framgång gällande detta arbetssätt vill man kunna mäta Nöjd Kund Index (NKI) för att kunna jämföra IT-projekt internt i företaget. Då tidigare forskning visat avsaknad av modeller innehållande både mätning av servicekvalitet samt NKI har lämplig litteratur studerats där det framkommit att modellen SERVQUAL är vedertagen för mätning av servicekvalitet och modellen American Customer Satisfaction Index (ACSI) är vedertagen för mätning av NKI. Detta har legat till grund för arbetets problemformulering och syfte. Syftet med arbetet är att skapa en vidareutvecklad modell för mätning av NKI för att jämföra IT-projekt internt samt återkommande mätning av servicekvalitet inom IT-projekt. Framtagande av denna modell har sedan skett genom forskningsstrategin Design and Creation. Intervjuer har genomförts för kravfångst till den vidareutvecklade modellen. Resultatet av denna forskningsstrategi blev sedan en vidareutvecklad modell baserad på ovan nämnda modeller med återkommande förhållningssätt för mätning av servicekvalitet inom IT-projekt och mätning av NKI för att jämföra IT-projekt internt i företaget. Den framtagna modellen har sedan verifierats genom ytterligare intervjuer med respondenter som innehar god erfarenhet från kundsidan av IT-projekt. Från dessa intervjuer kunde sedan slutsats dras att denna modell är att anse som applicerbar i empirin gällande IT-projekt. / In today's society, it is increasingly important for companies to retain their existing customers when competition becomes increasingly fierce. This means that companies are trying to take steps to nurture relationships with its customers. This problem is very relevant in the IT industry. In the IT industry, it is common to work agile in IT projects. Our partner has seen an increased need to measure service quality with a regular approach in IT projects, in order to measure the relevant variables that extend beyond the specifications. To measure success regarding this approach would be to measure Customer Satisfaction Index (CSI) of IT projects. As previous research demonstrated the absence of models containing both the measurement of service quality and CSI have literature studied where it emerged that the model SERVQUAL is established for the measurement of service quality and model the American Customer Satisfaction Index (ACSI) is established for the measurement of CSI. This has been the basis of work problem and purpose. The aim is to create an improved model for the measurement of CSI between IT projects and recurring measurement of service quality in IT projects. Creation of this model has been made through research strategy Design and Creation. Interviews have been conducted for requirements capture to the refined model. The result of this research strategy was then a further developed model based on the above models with recurring approach for the measurement of service quality in IT projects and measurement of CSI between IT projects. The resulting model is then verified through further interviews with respondents holding good experience from the customer side of IT projects. From these interviews conclusion could be drawn that this model is considered to be applicable in the empirical data regarding IT projects.
