Six Sigma for improving cash flow deficit: a case study in the food can manufacturing industry

Abstract

Purpose Cash flow deficit situations and working capital control are major challenges for many companies, especially those whose suppliers and clients have strong bargaining power. This study aims to describe the application of the Six Sigma methodology for solving these problems in a large German food can manufacturing company. Design/methodology/approach This paper follows the qualitative methodology of case study research. During different define, measure, analyse, improve and control process phases, the problem and critical aspects are identified to improve the quality of the payment process and improvements are suggested and implemented. Findings The results provide evidence of how Six Sigma can be useful in administrative–financial processes that are carried out within a company. This result is particularly interesting because it is about processes that have not applied Six Sigma methodology. For the company studied, this methodology has balanced its cash flow and this meant large amounts of savings, especially in bank interest to avoid having to ask for bank credits. Originality/value This case can be extrapolated to other companies, regardless of the company size, that present similar symptoms of cash deficit, especially if their bargaining power with suppliers and customers is low.

Benefits of implementing Six Sigma in competitive tendering process

“…Customer focus related-benefit (B2) Improved customer satisfaction has been identified by researchers (S anchez-Rebull et al, 2020;Dalalah, 2019;Ambekar and Hudnurkar, 2017) as one of the key benefits of Six Sigma implementation. This usually reduces the complaints from customers (Aboelmaged, 2010) and the risk to customers.…”

“…Another category of benefit identified is that related to process improvement. Some researchers (S anchez-Rebull et al, 2020;Patel and Desai, 2018) identify the ability of Six Sigma to improve the efficiency, effectiveness and reliability of operations as a benefit. Others (Antony et al, 2016) relate Six Sigma's ability to reduce non-value-added operations as a benefit.…”

“…Researchers argue that the benefits of Six Sigma are immense and not limited to financial gains (Alkasisbeh et al, 2018;Bodke et al, 2017). This explains why Six Sigma has in the last three decades been applied to wide range of organisations (S anchez-Rebull et al, 2020;Swami and Kadiwal, 2020;Dalalah, 2019;Antony et al, 2018;Laux et al, 2017;Antony et al, 2016). Several researchers have established benefits of implementing Six Sigma in manufacturing (Antony et al, 2019;Ambekar and Hudnurkar, 2017) and services (Antony et al, 2018) sectors.…”
