A Theory of Constraints Service Systems Improvement Method: Case of the Airline Turnaround Problem

Applying Goldratt’s Framework to the Banking System

“…The importance of the specific factors that support this claim (H1.1: Existence of indicators, H1.2: Existence of vocabulary, H1.3: There is a specific implementation method) was confirmed in the Portuguese banking reality. However, it should be noted that, according to the responses from the banking employees surveyed, the majority (88.9 %) attributed greater influence to the existence of a deployment method (Ellis, 2011;Motwani et al, 1996b;Reid, 2007), while also recognizing the intervention of the other two. Regarding H1.4, it was observed that TOC is one of least well known continuous improvement tools among the banking employees surveyed with 7.3 %, being surpassed only by Total Productive Maintenance with 4.9 %.…”

“…Although in recent years the literature related to the topic has significantly increased, the approaches are still too incipient to match the large number of studies on TOC developed for industry (Ellis, 2011;Motwani et al, 1996a,b;Reid, 2007).…”

“…(Ku, 2007;Reid, 2007;Shoemaker & Reid, 2005;Taylor & Thomas, 2008) 3 Applying the Theory of Constraints in Services: a review TOC is a theory created mainly for industrial process optimization (Davies et al, 2005;Gillespie et al, 1999;Ku, 2007;Mabin & Balderstone, 2003;Motwani et al 1996a,b;Reid, 2007;Shostack, 1977;Siha, 1999;Spencer, 2000). The terminology used, its indicators, the tools for managing problems, the kind of thinking, their premises and, in general, all elements involved, were developed according to the specific characteristics of the processes to transform raw material into tangible products (Ellis, 2011;Shostack, 1977;Siha, 1999).…”

“…Although there is a stark shortage of the TOC developments specifically for the sector, compared to the vast number of existing studies in industry (Bramorski et al, 1997;Ellis, 2011;Ku, 2007;Motwani et al, 1996a,b;Reid, 2007;Shoemaker & Reid, 2005;Shostack, 1977;Siha, 1999), some studies related to the area have shown the relevance of and current interest in the matter, which deserves to be more fully explored from new and different perspectives, the main aim of this study. For accomplishing this main purpose, this study also aim at analyzing the literature, reviewing the different applications of the Theory of Constraints as well as the different concepts of each element of TOC: Inventory, Throughput, Operating Expenses and Constraints.…”

Theory of Constraints in the Service Sector: Characterization for Banking and Analysis of the Factors Involved in Its Adoption

“…The historical success of TOC and the tertiary sector's need to increase its productivity serves to highlight the importance of further investigations that combine these two areas. Although there is a stark shortage of TOC developments specifically for the sector, compared to the vast number of existing studies in industry [6][7][8][9][10][11][12][13][14], some studies related to the area have shown the relevance of and current interest in the matter, which deserves to be more fully explored from new and different perspectives, the main aim of this study. Actually, the TOC is providing a process of centering the attention on the critical areas' improvement [7], and thus has the potential for much faster improvement.…”
