This paper aims to empirically analyze how adaptive collaboration in supply chain management impacts demand forecast accuracy in short life-cycle products, depending on collaboration intensity, product life-cycle stage, retailer type and product category.

The authors assembled a data set of forecasts and sales of 169 still-camera models, made by the same manufacturer and sold by three different retailers in France over five years. Collaboration intensity, coded by collaborative planning forecasting and replenishment level, was used to analyze the main effects and specific interaction effects of all variables using ANOVA and ordered feature evaluation analysis (OFEA).

The findings lend empirical support to the long-standing assumption that supply chain collaboration intensity increases demand forecast accuracy and that product maturation also increases forecast accuracy even in short life-cycle products. Furthermore, the findings show that it is particularly the lack of collaboration that causes negative effects on forecast accuracy, while positive interaction effects are only found for life cycle stage and product category.

Investment in adaptive supply chain collaboration is shown to increase demand forecast accuracy. However, the choice of collaboration intensity should account for life cycle stage, retailer type and product category.

This paper provides empirical support for the adaptive collaboration concept, exploring not only the actual benefits but also the way it is achieved in the context of innovative products with short life cycles. The authors used a real-world data set and pushed its statistical analysis to a new level of detail using OFEA.

Since Masaaki Imai coined the term Kaizen in the mid 1980s it has been regarded as a key element in the competitiveness of Japanese companies. However, even though Kaizen was defined by the author who created the term, writings by scholars and practitioners in the field exhibit a certain degree of ambiguity and inconsistency. Finally, there is a clear need to develop this theory in the field of operations management. The purpose of this paper is to analyse Kaizen in the academic and practitioner literature, in order to better understand it and further explore and contribute to its potential theoretical profile.

A literature review was carried out using Kaizen as a search term. Various databases were used for this purpose and books written by both scholars and by practitioners on the subject were also consulted. The literature concerning Kaizen was methodically analysed and categorised.

The findings of the study indicate that Kaizen is presently displayed under three perspectives or umbrellas, which include a series of principles and techniques. By comparing the three perspectives, a set of guiding principles and/or cornerstones for Kaizen have also emerged.

Analysis and classification is based on the literature that has been found and reviewed, along with the knowledge of authors on the subject, and may include other features as well as other angles of analysis.

The Kaizen literature review is very limited. In writing this paper a considerable number of articles and research related to Kaizen has been reviewed. This review resulted in an initial classification of Kaizen (three umbrellas) and four major topics, which may prove useful for managers or executives who are introducing or developing Kaizen in their organizations.

As far as the authors are aware, this is one of the first papers that proposes a literature review in an attempt to clarify Kaizen, both in academic and practitioner ambits.

This paper aims to present a structured and comprehensive review of relevant works, collected through a systematic methodology and clustered into nine meaningful categories on megaproject management systems and the current requirements for improved industrial megaprojects.

The methodology employed in this paper retrieves relevant works from available online citation indexes that are published in peer-reviewed journals and other reliable sources from 2000 to 2021.

It has been observed that the literature on megaproject management is still premature and requires further research to understand better the main gaps and effects of large-scale and typically complex megaprojects. Significant improvements are needed towards covering gaps to address the project management system holistically over the entire project life cycle. There are no clear guidelines for achieving a complete and conclusive project management system and enhancing future megaprojects' management capabilities.

This paper provides a clear picture of the existing literature on megaproject management systems, contributing insights for successful megaproject projects. Additionally, the holistic analysis identifies gaps in the body of knowledge, revealing avenues for future research.
