Ensuring customer satisfaction and stakeholder satisfaction in product and service delivery by providing competitive advantage has started to attract attention as an important priority not only for the private sector but also for public institutions. In this context, organizations can initiate the changes required by the age by applying post-modern management approaches and create proactive and reactive strategies by analyzing the environment. There are various methods used by organizations in this process. Six sigma concept is considered as a concept that advocates perfectionism and error-free in terms of providing customer satisfaction and increasing quality in many businesses, especially in production enterprises. On the other hand, lean production and management practices are also the art of embracing being free from elements that are not needed in the realization of activities. The Lean Six Sigma concept is a philosophy that focuses on business units and processes together. Lean Six Sigma advocates perfectionism and simplicity in all corporate processes by addressing the advantages of Six Sigma and Lean Management in a single managerial technique. In this research, it is aimed to examine Lean Six Sigma theoretically by considering Six Sigma and Lean Management techniques which are effective in the emergence of Lean Six Sigma concept. Referring to the studies on Six Sigma, Lean Management and Lean Six Sigma, it was concluded that the concept should be adopted and implemented in the private and public sector, not in a single process or unit, but in all institutions.","PeriodicalId":158468,"journal":{"name":"Journal of Life Economics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116132333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Böylelikle GYO’lar, yatırımcıların yalnız başlarına satın alımlarını gerçekleştiremeyecekleri gayrimenkullere ortak olabilme imkânı sunmaktadır. Özellikle, gelişmekte olan ülkelerde gayrimenkul yatırımları, diğer yatırım alanlarına göre daha az riskli olmaları ve yatırımcılara uzun vadede daha yüksek getiri sağlamaları nedeniyle yatırımcılar için daha cazip görünmektedir. Ayrıca, GYO’ların kârlılık oranlarının borsa performanslarını nasıl ve ne yönde etkileyeceği de yatırımcılar için önem taşımaktadır. Türkiye’de son yıllarda gayrimenkul sektöründe gözlemlenen hareketlilik, yatırımcıların gayrimenkul projelerine yönelmelerinin yanı sıra GYO’lara yatırımda bulunarak kazanç sağlama arzuları, bu sektörde faaliyette bulunan şirketlerin başarımlarını yakınen takip etmeyi zorunlu kılar. Buradan yola çıkarak, Borsa İstanbul’da işlem gören GYO’ların kârlılık oranlarının borsa performans endekslerinden piyasa değeri/defter değeriyle (PD/DD) ilişkisi panel regresyon analizi yardımıyla analiz edilmiştir.

In estimating the SVAR regression model, granger causality, impulse-response functions and forecast error variance decomposition were employed and evaluated. The sample consisted of Namibian commercial banks. By auditing liquidity data between 2009 and 2018, empirical results showed that liquidity risk is caused by a combination of structural shocks. The granger causality, impulse-response functions and forecast error variance decomposition documented that credit risk (non-performing loans) is key factor affecting liquidity conditions in Namibia in the medium to long run. In addition, the empirical results showed that quality earnings (ROA) have minimal impact on liquidity conditions in the short run. Reforming assets quality policies and earnings quality policies can be valuable policy tools to minimize liquidity shortages and avoid insolvent banks in Namibia.","PeriodicalId":158468,"journal":{"name":"Journal of Life Economics","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115625084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
