Abstract

Purpose

The purpose of this paper is to shed light on the studies regarding the influential elements that contribute to the sustainability of continuous improvement (CI) programs. It aims to define the notion of sustainability and to identify and explore the influential elements that could encompass such a definition.

Design/methodology/approach

A comprehensive literature review was conducted to categorise various interpretations of sustainability into distinct dimensions. This approach also identified 16 influential elements that have the potential to sustain CI programs. A self-assessment survey involving 80 French companies was used to evaluate these elements through the Plan, Do, Check, Act framework. In addition, a maturity-benchmark model is introduced to help evaluate the degree of maturity of the most influential elements of CI programs.

Findings

The results highlight the inherent paradox in sustaining CI programs, where robustness and adaptability must coexist. The study identifies a relationship between influential elements and organisational maturity levels, offering actionable insights to help companies advance through these stages. Human-centered elements, such as leadership and employee engagement, have the greatest impact on CI sustainability, emphasizing the importance of fostering a people-centric culture. Conversely, operational elements are less influential, suggesting a need for balanced strategies.

Originality/value

This paper discusses a topic that is rarely addressed, namely, how to sustain CI programs within a CI framework. This paper provides a novel synthesis of influential elements and their relationships to organisational maturity within a CI framework, challenging traditional static views of sustainability. By emphasizing the dynamic and evolving nature of CI programs, it bridges theory and practice, offering organisations a practical model for continuous reassessment and adaptation.

Abstract

Purpose

This paper deals with the subject of “Lean Normalization.” The purpose of this paper is to propose a comprehensive methodology which combines the benefits of both International Organization for Standardization (ISO) standards and Lean Management. The application of this methodology leads manufacturing or service companies to certification without creating more documentation. It guarantees agility and flexibility in the day-to-day management of the company, and induces lower costs and reduced times. This methodology provides a new way of tackling the implementation of ISO standards in a company.

Design/methodology/approach

This methodology is based on the synergistic combination of both ISO standards (Quality Management System) and the key concepts of Lean Management. After a short presentation of ISO standards and Lean Management, the possibility of implementing a synergy between these two different approaches will be discussed. At this point, ISO 9001 standards will be focused on. The proposed methodology will be introduced step by step. Each step of the model will be formalized using the Structured Analysis and Design Technique graphic representation tool. Moreover, each step is associated with a key concept of Lean Management. In order to illustrate the proposed method, an example of implementation will also be presented.

Findings

To show the feasibility of this methodology, this paper finishes with a summary of the results achieved in a company and draws some interesting conclusions. Companies have the possibility of achieving certification in combination with a Lean Quality Management System (LQMS): a one-page quality manual, only ten records, no major non-conformities and no customer complaints over a two-year period.

Research limitations/implications

The methodology may have to be adapted to better suit the needs of companies seeking to implement the latest version of the ISO 9001 standards.

Practical implications

This paper presents the deployment of ISO 9001 standards whilst simultaneously respecting key Lean Management concepts. The practical results for enterprises are the implementation of an LQMS leading to a certification.

Social implications

This paper presents a new method combining both ISO standards and Lean Management concepts to achieve certification with an LQMS.

Originality/value

Due to its simplicity and the relevance of its steps, the proposed methodology can be applied to companies with a guaranteed success of certification.

Abstract

This paper reports on the development of a new method for suspended test reliability assessment and modeling. Reliability suspended tests are performed in order to accelerate testing duration and then to obtain information quickly on the life distribution of products. During suspended tests, products are randomly removed from initial samples before failure. The proposed method, which is an alternative to Johnson’s approximation, corrects the failure order number of failed products each time a product is suspended. The method is applied within a global approach carried out using the ADONIS software. The software developed for this purpose helps users to assess and model reliability for different test types (complete, censored, truncated, suspended, etc.). The proposed method is compared with the cumulated chance rate method and Johnson’s method. The three methods are then evaluated with reference to complete tests. Several simulations are carried out to validate this evaluation. The three main distributions (Weibull, exponential, normal) are used for reliability modeling. Reported simulations show that the proposed method provides better results than the two other methods in 80 per cent of the tests performed.

Abstract

Purpose

In spite of the large body of literature on success factors of enterprise resource planning (ERP) implementation, there is a need to explore its multinational dimension. The purpose of this paper is to explore the impact of the conflict between parent and subsidiary on the process of ERP implementation in a multinational enterprise (MNE).

Design/methodology/approach

Using an interpretive case study methodology, this paper analyses the theoretical frameworks of parent-subsidiary conflict and applies them to interpret an in-depth case study and generate a set of managerial prescriptions.

Findings

Theoretical analysis and case evidence suggest that managing parent-subsidiary conflict is a critical success factor of ERP implementation in MNEs.

Research limitations/implications

This case relates to a diversified multinational group producing a variety of materials through subsidiaries. The data collection includes multiple sources in the company, and strong theoretical development provides a high level of generalizability. The paper shows that managers should consider the impact of conflict from the planning stages of any multinational ERP implementation.

Practical implications

A detailed set of practical managerial prescriptions is derived from case and theoretical analysis. These prescriptions provide guidance to multinational managers planning a successful global ERP rollout.

Originality/value

Although parent-subsidiary conflict is clearly a major factor in multinational ERP implementations, this topic has never been analysed in detail in the literature. This paper breaks new ground applying grounded theoretical frameworks of parent-subsidiary conflict to an implementation case, and providing managerial guidance for implementation decisions.

Abstract

Purpose

The purpose of this paper is to consolidate the critical success factors (CSFs) as published in enterprise resource planning (ERP) implementation case studies. The authors perform the analysis and propose the final CSFs based on the reported ERP implementation process stages.

Design/methodology/approach

The paper follows the eight category coding steps proposed by Carley (1993) and utilizes only ERP implementation case studies to identify a distinct set of critical success factors. The 37 case studies used in this paper provide a reasonable sample from different countries and contexts. Two methodologies were followed, one for the literature review process and the other for the analysis and synthesis.

Findings

Out of 64 reported CSFs that were extracted from the literature and subsequent detailed analysis and synthesis the authors found a total of 22 factors that are distinct. These factors which encompass change management, are proposed with five ERP implementation stages.

Research limitations/implications

The final set of success factors proposed in this study gives a consolidated and unified view of the significant variables to be considered during all the stages of ERP implementation. The research is limited to case study literature and does not account for ERP implementation models and frameworks. Another limitation would be the scope of the literature searched which is that of the Management Information Community.

Practical implications

The proposed CSFs can be used by practitioners in five ways: assess implementation of an ERP; ex-ante assessment; comparative analysis with other implementation experiences; utilize CSFs from model as part of key performance indicators; and utilize the model to establish a concise strategy to project management process for the ERP implementation.

Social implications

ERP implementation is complex. The promise has not yet been fully realized. An ERP-enabled organization entails primarily strategy and change management. To that effect, all stakeholders are impacted by ERP implementation. This paper, identified CSFs extracted from cases of ERP implementation and proposes a model to support its project management, user satisfaction and sustainability. The results aim at reducing costs, maintaining timeline, reducing employee anxieties and with a successful implementation, better service to customer base.

Originality/value

This paper is the first attempt to present a consolidated list of CSFs and mapping them to the stages of an ERP implementation as reported from the industry. It originality is its focus on utilizing rigorous published case studies with the hope that future case studies would utilize the work to report on the same factors. The value is that as the case studies are increased, comparison and differentiation between is enhanced.

Abstract

Purpose

This paper proposes an integrated value stream mapping (VSM) for a complex assembly line to improve the leanness of a complex automotive component manufacturing organization.

Design/methodology/approach

This study depicts the application of VSM at the case organization, where top management is concerned about the challenges of higher cycle time and lower productivity. Gemba walks were conducted to establish the concept of “walk the flow, create the flow” along the assembly line. The multi-hierarchical cross-functional team developed the current value stream map to know the “as-is” state. Then, the team analysed the current VSM and proposed the future VSM for the “to-be” state.

Findings

The integrated VSM shows different processes and work cells, various wastes, non-value-added activities, cycle time, uptime and the material and information flows for both products of the assembly line on the same map. The integrated VSM reduced cycle time, non-value-added activities, work in process inventory and improved line efficiency and production per labour hour for both the products, simultaneously.

Research limitations/implications

The limitation of the study is that the study focussed only on the application of VSM for one complex assembly only. Future research may be conducted using the developed integrated VSM approach in other complex production environments.

Practical implications

Managers can identify and reduce system waste by incorporating the concept of integrated VSM in a complex production or assembly environment where two or more products are being manufactured/assembled with low similarity.

Originality/value

The application of VSM for assembly lines is highly challenging because of merging flows, a large number of child parts in the lines and assembly of more than one product on the same line.

Abstract

Purpose

The present study aims to resolve the adjustment problem of cavitation bubble number density in simulations of the cavitating flows within the diesel injection nozzle holes using a two-fluid cavitation model.

Design/methodology/approach

The basic rule that determines the variations of cavitation bubble number density has been checked through the scaling analysis of a two-fluid model under the assumption of hydrodynamic similarity of the cavitating flows. Moreover, a phenomenological model for the number density of cavitation bubbles that takes the hydrodynamic effect into account has been developed through the combined analysis of cavitation bubble dynamics and internal flow characteristics of diesel injection nozzle holes. This new model has also been validated by the discharge coefficient measures in a wide range of injection conditions.

Findings

The values of cavitation bubble number density must rationally match changes both in liquid quality effect and in hydrodynamic effect corresponding to different cavitating flows. The validation results show that the two-fluid cavitation model together with this new cavitation bubble number density model predicts well both the cavitation content inside the diesel nozzle hole and the relationship between discharge coefficient and cavitation number, and the new cavitation bubble number density model has the potential to further expand the application range of the two-fluid cavitation model.

Originality/value

This study provides insight into hydrodynamic effect corresponding to cavitating flows inside diesel nozzle holes and presents an idea to model the cavitation bubble number density phenomenologically. The model idea and the developed model are useful to researchers and engineers in the area of nozzle internal flow and cavitating flow.

Abstract

Purpose

Lean construction (LC) consists of very effective techniques; however, its implementation varies considerably from one industry to another. Although numerous lean initiatives do exist in the construction industry, the research topic related to LC implementation is still unexplored due to the scarcity of validated assessment frameworks. This study aims to provide the first attempt in developing a structural model for successful LC implementation.

Design/methodology/approach

This study developed a Lean construction model (LCM) by critically reviewing seven previous LC frameworks from different countries, defining 18 subprinciples grouped into 6 major principles and formulating testable hypotheses. The questionnaire was pre-tested with 12 construction management experts and revised by 4 specialized academics. A pilot study with 20 construction units enhanced content reliability. Data from 307 Moroccan construction companies were collected to develop a measurement model. SPSS V. 26 was used for Exploratory Factor Analysis, followed by confirmatory factor analysis using AMOS version 23. Finally, a structural equation model statistically assessed each construct's contribution to the success of LC implementation.

Findings

This work led to the development of an original LCM based on valid and reliable LC constructs, consisting of 18 measurement items grouped into 6 LC principles: Process Transparency, People involvement, Waste elimination, Planning and Continuous improvement, Client Focus and Material/information flow and pull. According to the structural model, LC implementation success is positively influenced by Planning and Scheduling/continuous improvement (β = 0.930), followed by Elimination of waste (β = 0.896). Process transparency ranks third (β = 0.858). The study demonstrates that all these factors are mutually complementary, highlighting a positive relationship between LC implementation success and the holistic application of all LC principles.

Originality/value

To the best of the authors’ knowledge, this study is the first attempt to develop a statistically proven model of LC based on structural equation modelling analysis, which is promising for stimulating construction practitioners and researchers for more empirical studies in different countries to obtain a more accurate reflection of LC implementation. Moreover, the paper proposes recommendations to help policymakers, academics and practitioners anticipate the key success drivers for more successful LC implementation.
