Purpose The purpose of this paper is to explore the applicability of lean construction (LC) concepts and tools in necessary, but non-value-added activities (NVAA) in small and medium-sized enterprises (SME). The application of the lean tools in this way facilitates the flow of information and handling material, improving productivity, quality and performance. Finally, practical results motivate a discussion on the real potential of LC principles and on the challenges related to its implementation. Design/methodology/approach The methodology makes use of direct involvement in the environment under study. Some of the activities performed were the value stream mapping and time and motion studies of the company’s process selected, identification of wastes and the proposition of improvements to be implemented. Findings The main findings are related to the benefits of the application of LC not only in value-added activities but in activities that can influence the development and workforce planning, especially for SME businesses. This company should be able to achieve better management decisions and results after implementing the LC principles, overcoming the limited resources. Originality/value This proposed method helps in overcoming the lack of systematic procedures, enabling LC in activities that not add value properly. It has the advantage of integrating existing tools and models effectively, which not only improve the shortcomings of the conventional methods but also result in more convenient calculation and application.

PurposeThe purpose of this paper is to introduce a new methodology called overall greenness performance for value stream mapping (OGP-VSM). Using value-added concepts, this approach has the potential to integrate, measure, control and improve productive and environmental performance in accordance with a company’s context.Design/methodology/approachThe OGP-VSM approach was developed by reviewing and integrating the environmental aspects of existing lean thinking tools and approaches.FindingsThis research revealed the lack of practical integration between productive and environmental performance. Using OGP-VSM, managers can see that environmental practices have a direct impact on productivity. OGP-VSM allows a balance to be found between lean and green practices in order to achieve the simultaneous improvement of productivity and environmental performance.Practical implicationsThe proposed approach is applied to a case study in an automotive company in Spain and lays the groundwork for moving toward functional environmental sustainability in manufacturers.Originality/valueCompanies are increasingly implementing environmentally focused practices. Pursuing environmentally friendly (green) performance poses several challenges, but it also affords opportunities to create new methodologies for generating a competitive advantage for manufacturing companies. There are a limited number of approaches to drawing together the elements and attributes that are essential for a holistic, practical and long-lasting improvement of environmental performance in the manufacturing sector.

PurposeThis research develops value stream mapping (VSM) for L'Oreal's artwork process, to eliminate waste, reduce lead time and identify stages that can be automated, which makes the process less prone to human error and more responsive to fulfilling business-to-business customer requirements. In addition, amendments frequently occur slowing down the artwork process. In this context, VSM is applied to L'Oreal's artwork process to reduce lead time, human error and missed deadlines.Design/methodology/approachThis study uses data from L'Oreal's artwork tracker from 2018–2019, which is manually tracked by the launch team. The service level agreement and task time data have been collected from 12 employees representing the launch, factory and marketing teams working on the artwork process. Qualitative feedback was also obtained from nine employees to validate the VSM for L'Oreal's artwork process.FindingsVSM identified stages that can be streamlined and automated in L'Oreal's artwork process, which makes the process more efficient and responsive to changing scope of the artworks. 50% of the stages have been eliminated from the manual artwork process, resulting in a reduced lead time of 10.5 days and a reduction of 28% spent on the process. This allows the artwork process to be more agile to the requirements of business-to-business customers. The proposed VSM shows a 73% increase in value-added time for a renovation and a 75% increase in value-added time for new product developments.Originality/valueVSM has been specifically designed, developed and analyzed for L'Oreal's artwork process, in order to make the process more efficient and responsive to business-to-business customer’s requirements.

Purpose The purpose of this paper is to present a road map to implement Lean-Kaizen concept using value stream mapping (VSM) to identify hidden continuous improvement opportunities in a small and medium-sized enterprise (SME) located at the non-capital region of India. Design/methodology/approach From the collected data, a current state map was prepared that indicated the current operating situation of selected SME. The takt time was calculated and those processes which attained higher cycle time (C/T) than takt time were identified. The continuous flow processing was achieved by adjusting C/T of each process and supermarket pull system was developed to control the production at the workstations. Finally, a future state map was developed that served as a guide for future lean activities. Few problems were identified to realize the future state. The “5-why” analysis was used for identifying root causes of these problems and Kaizen events were proposed as solutions. In this case study, one Kaizen event was identified in which brainstorming technique was used to control the variation caused by unorthodox fixture design for clamping and de-clamping of case product and thus eliminated non-value-added activities performed by the operator on a milling machine. Findings Before and after implementation of value stream map, the data obtained were analyzed and eliminated rework time, reduced inventory level, reduced lead time and C/T, improved productivity and product quality are presented as finding. Lean-Kaizen provides a better chance for every individual of the industry to have a hand in achieving organization’s goals to attain continuous progress in productivity and quality of the product. Even good understanding of the concept of lean tools and techniques by SMEs, the employee willingness and motivation to identify and eliminate wastes are found feeble. Originality/value This study is among best practices to identify hidden improvement opportunities in the regular production of the product to increase productivity and improve quality using value stream map. The research paper gives useful understandings to the lean implementers, Kaizen identifiers, consultants and researchers.

PurposeThis research aims to improve the performance and productivity of low-level technology organizations using lean tools – value stream mapping (VSM). In order to investigate the application of VSM in low-level technology organizations, this study takes footwear manufacturing organizations as a case study.Design/methodology/approachIdentifying a suitable organization was the first step for conducting the case study, followed by product family identification. Time and motion studies are used to determine the cycle time and identify the value-adding and non-value-adding activities, respectively. After making necessary observations and calculations, the current state map was developed. Different improvement proposals were identified, and the future state map was constructed.FindingsAs a result, 56.3% cycle time reduction and 69.7% reduction in lead time were obtained, confirming its application in low-level technology organizations to improve their performance and productivity. This promising result indicates that a significant improvement can be achieved if VSM is applied in low-level organizations other than footwear industries, such as the clothing and furniture industries. Speed is investigated to be one of the parameters in motion study.Research limitations/implicationsThis study focuses on low-level technology organizations, specifically leather shoe manufacturing industries. But experiences gained from implementing this study are realistic and applicable in similar organizations.Practical implicationsPerformance and productivity improvement are critical issues to be addressed in low-level technology organizations, especially in the leather footwear manufacturing sector. This can be achieved through VSM by identifying and removing the wastes. VSM can be applied to low-level organizations as well. VSM is a powerful tool that helps managers and practitioners in identifying wastes and opportunities for improvement.Originality/valueThe paper addresses applicability of VSM in the production process of low-level technology organizations with an original industrial case study in Ethiopia.

PurposeThe assorted piece-wise retail orders in a cosmetics warehouse are fulfilled through a separate fast-picking area called Forward Buffer (FB). This study determines “just-right” size of FB to ensure desired Customer Service Level (CSL) at least storage wastages. It also investigates the impact of FB capacity and demand variations on FB leanness.Design/methodology/approachA Value Stream Mapping (VSM) tool is applied to analyse the warehouse activities and mathematical model is implemented in MATLAB to quantify the leanness at desired CSL. A comprehensive framework is developed to determine lean FB buffer size for a Retail Distribution Centre (RDC) of a cosmetics industry.FindingsThe CSL increases monotonically; however, the results concerning spent efforts towards CSL improvement gets diminished with raised demand variances. The desired CSL can be achieved at least FB capacity and fewer Storage Waste (SW) as it shifts towards more lean system regime. It is not possible to improve Value Added (VA) time beyond certain constraints and therefore, it is recommended to reduce Non-Value Added (NVA) order processing activities to improve leanness.Research limitations/implicationsThis study determines “just-right” capacity and investigates the impact of buffer and demand variations on leanness. It helps managers to analyse warehouse processes and design customized distribution policies in food, beverage and retail grocery warehouse.Practical implicationsProposed buffering model offers customized strategies beyond pre-set CSL by varying it dynamically to reduce wastages. The mathematical model deriving lean sizing and mitigation guidelines are constructive development for managers.Originality/valueThis research provides an inventive approach of VSM model and Mathematical algorithm endorsing lean thinking to design effective buffering policies in a forward warehouse.

Purpose – The aim of this paper is to investigate the relationship between corporate performance and Value Added Intellectual Coefficient (VAICTM) on the one hand, and the relationship between the variations in market value and the variations in VAIC on the other hand. Design/methodology/approach – Starting from the VAIC model, 23 Italian listed companies were examined with the aim of investigating the relationship between VAIC and the performance of the firms in the sample. The analysis was divided into two stages. In the first stage, eight models of linear regression were estimated to verify the presence of a positive and statistically significant relationship between M/BV and VAIC and between accounting performance indicators (ROE, ROI, ROS) and the VAIC. In the second stage, six other models were tested, considering as an independent variable the variations in VAIC and the variations in profitability indicators. Findings – The outcomes of the application stress the importance of VAIC in the explanation of the variations in MV and its role as “additional coefficient” in the analysis of equity performance. Originality/value – This methodology highlights some very interesting aspects. In particular, whereas the relationship between M/BV and VAIC and between profitability indicators (ROI, ROE, ROS) and VAIC is statistically insignificant, the subsequent analysis highlights the importance of VAIC as a variable capable of increasing the explanatory power of the regression in a cross-sectional perspective.

The importance of lean manufacturing concepts has been discussed many times over the few decades. The most important elements in lean manufacturing practices are value stream mapping (VSM), Kaizen events, load leveling (heijunka), etc. In this case study, a real-world clock assembly simulation has been used to study the performance improvement in terms of production flow and lead time after introducing lean concepts. In each round of simulation, the lean concepts have been introduced one by one and performance metrics were recorded. After implementing the concepts, the productivity was improved enormously. So, this simulation study emphasizes the importance of continuous improvement of production flow through lean concepts in a real production setting.
