Abstract

Purpose

The first purpose of this paper is the implementation of Lean Six Sigma (LSS) in a manufacturing company operating in South East Europe in order to understand the importance of critical success factors (CSFs) in LSS adoption and to find out the benefits that the company gained. The second purpose is to propose a standardized toolset based on DMAIC phases, for the application of LSS in small scale projects, in order to facilitate LSS adoption by more manufacturing companies.

Design/methodology/approach

This case study is based on the interlacement of the Yin's method about case studies and the DMAIC method for the improved deployment of LSS.

Findings

The analysis of this case study shows that the company attained to benefit financially, operationally and organizationally from the implementation of LSS. The already existing mentality of CI inside the company helped the project procedure and the application of changes and improvements fulfilling LSS adoption CSFs.

Practical implications

The paper constructs a toolset and studies the role of CSFs in order to achieve the desirable benefits in a manufacturing environment, constituting a guide for future LSS initiatives.

Originality/value

Abstract

Purpose

The purpose of this paper is the implementation of Lean Six Sigma (LSS) in a manufacturing small and medium-sized enterprise (SME) in Greece in order to understand the contribution of LSS in its process improvement and to identify the parameters playing a crucial role in LSS adoption by SMEs. The ability to achieve high-effect improvements without cost investment is also examined to cope with low investment margin that is a characteristic of SMEs.

Design/methodology/approach

This case study is based on the combination of Define, Measure, Analyze, Improve and Control (DMAIC) phases with the Yin's method for case studies for a complete and efficient implementation and presentation of the project.

Findings

The analysis of this case study revealed that by accomplishing specific critical success factors for the fulfillment of the LSS project, the company attained important benefits by utilizing only the working hours of employees. It was also found that the improvements of LSS projects can be measured using other metrics which can indirectly be translated into monetary terms.

Practical implications

The paper can be a useful guide of how SMEs can achieve high-impact improvements with low or no investment cost utilizing LSS initiatives in small-scale projects.

Originality/value

According to the literature, there is a need for more case studies concerning LSS implementation in SMEs. Examples of how low-cost/high-effect improvement initiatives can be implemented have not been adequately presented before. The assessment of the impact of improvement initiatives with non-monetary measures is also innovative.

Abstract

Purpose

The purpose of this paper is the development of a reference model contributing to the identification of the retail supply chain activities that can be improved by the implementation of Lean Six Sigma (LSS) initiatives, following DMAIC steps and using proposed tools, based on contemporary technologies and best practices.

Design/methodology/approach

The reference model was developed combining the existing literature knowledge about the areas of supply chain that LSS can improve and the data collected by two big retailers in Greece about their supply chain operation. The integration of two sources of information led to the modeling of the retail supply chain processes and the proposal of appropriate LSS initiatives for their improvement.

Findings

This paper aimed to detect the pain points of a retail supply chain, which can be achieved by following the steps of DMAIC and applying specific LSS initiatives as described in the reference model, to introduce the trends of the sector in terms of logistics and supply chain.

Practical implications

The reference model of this paper can be used as a comprehensive guide of LSS implementation in the retail supply chain and help the companies of such a significant sector for the economy.

Originality/value

The literature review revealed that there is a lack of publications concerning LSS implementation in retail supply chain and in the retail sector in general. The development of this model contributes to the filling of this gap by providing a complete reference model, which strives to overcome the barriers of LSS adoption in retail supply chain.

This study has been conducted by reviewing 58 papers, found in top journals, coming from European institutions that present studies of European companies and fulfill the selected inclusion criteria.

Findings

The analysis of the literature revealed the level of penetration of the LSS methodology in organizations of each European country. The study of the papers revealed the sectors and the size of companies that are more active in LSS application, the method used in each project, the tools which are deployed and the interconnection between LSS and other topics through the project implementation.

Research limitations/implications

The limited access provided by the authors’ institution only to three major publishers (Emerald, Elsevier, Taylor and Francis) and the focus of the search only in European organizations were the main limitations of this review.

Practical implications

This paper provides both academics and practitioners with valuable insights about LSS implementation in European organizations, presenting a complete analysis framework of the literature and highlighting gaps for further research.

Originality/value

An extended and detailed analysis of LSS adoption in Europe has not been conducted before. This review presents a clear view about how LSS projects in European organization have been applied so far and suggests ways of how the literature could be enriched to facilitate the LSS implementation.

Abstract

Purpose

The purpose of this paper is to describe and analyze the benefits of the application of a requirements engineering framework to assist Enterprise Resource Planning (ERP) development. This framework combines the technology-driven and the process-driven approaches for requirements analysis and implementation. Specific business process modeling methods enhance the framework and assist the formulation of the functional specifications of the ERP system and the management of requirements.

Design/methodology/approach

A case study strategy was chosen as the most appropriate method to answer the research question and test the theoretical propositions. The case study’s unit of analysis is a Greek manufacturing company and its ERP implementation project. A requirements engineering framework enhanced with business process modeling methods was applied and the results were evaluated using metrics for ERP implementation success. Data were collected using multiple sources of evidences, including interviews with various stakeholders, structured questionnaires, direct observations, vendors’ functionality papers and company’s documentation.

Findings

This study proves that the configuration of ERP’s reference models together with the adjustments of organization’s processes, provided through a structured requirements engineering framework can lead to reliable functional specifications, a smooth transition to an ERP system and, eventually, to successful ERP implementation, concerning its alignment with requirements.

Research limitations/implications

A single case study is conducted in a typical manufacturing company, providing opportunities for further research in other industries, testing in parallel well-defined requirements and other success factors for ERP implementation.

Originality/value

The paper fulfils the identified needs for applied methodologies and frameworks for requirements engineering which can assist successful ERP implementations.

Abstract

Purpose

The purpose of this paper is to investigate internet adoption of very small B2B firms in Greece. This study aims to construct a model which will classify companies according to internet activities undertaken and then to explore whether different adoption can be interpreted by business demographics and a limited number of perceived barriers.

Design/methodology/approach

This empirical research was carried out by the means of survey focussing on the Greek jewellery industry. Data were submitted to a sequence of statistical analyses resulting to a model of Internet adoption. The model was then bench marked to representative domestic and international adoption patterns.

Findings

Firms can be classified into three groups, ranging from non-adopters to relatively mature adopters, similarly to previous patterns of international B2B small to medium enterprises. Business size and type, international cooperation and knowledge with regards to internet proved to be significantly correlated to adoption status.

Research limitations/implications

The paper focusses on one Greek business sector and thus the applicability of its results to cross-type international micro-businesses remains questionable.

Practical implications

The findings of this study can assist company owners to plan their internet strategy, software vendors to target firms by offering tailored solutions and governmental authorities to implement initiatives aiming to confront the highlighted internet adoption disablers.

Originality/value

This is one of a few information and communication technology studies that focus on very small companies and perhaps the only one providing an empirical classification model of internet adoption for this business size.

Abstract

Purpose

This paper aims to construct an assessment framework to establish a maturity model for Web Electronic Services offered at a local government level and investigate the maturity of Greek municipalities in the E-Government field, trying to correlate how this is affected by demographic variables.

Design/methodology/approach

An original assessment framework regarding municipal Electronic Services was created based on the literature review. The assessment framework was included in a methodological approach supported by the PROMETHEE II method, as well as by selected statistical methods. The framework and the methodological approach were applied in the case of Greek municipalities.

Findings

The analysis revealed the low maturity level of Greek municipalities in Electronic Services sector. The Greek case study indicated that the proposed framework and methodological approach could provide useful insights to municipalities for the improvement of its E-Government Web services based on their strategic preferences.

Research limitations/implications

The assessment took place only in Greece, assessing all the country's municipalities and conducting research only in the municipalities’ websites. The proposed methodology suggests that the PROMETHEE II multi-criteria decision analysis method can support the assessment of the maturity level of local government entities. Moreover, the combination of the PROMETHEE II–empowered assessment framework with demographic statistical analysis can assist orthological decision-making concerning future investments in Web Electronic Services. The methodology could be a good option for future research efforts (assessments) in municipalities, in Greece and worldwide.

Practical implications

The framework is both easy to use and fairly complete. The fact that the assessment was conducted in all the Greek municipalities makes it much more reliable, as it provides the whole picture. The suggested methodology which includes the proposed framework could be used in the cases of municipalities in other countries to assist future actions concerning the investment in Web Electronic Services.

Originality/value

This study provided a medium-size framework, being both complete and easy to use during the evaluation process of all the municipalities in Greece. In addition, the statistical analysis received data from a decision-making tool to execute the clustering (Cluster analysis is usually performed based on the raw data).
