Abstract
Purpose
The purpose of this paper is to define the “fast evolving industry” (FEI) and its supply chain management (SCM) challenges. The authors review and structure the literature regarding integration strategies and implementation methods to develop a strategic decision-making framework for SCM in the FEI.
Design/methodology/approach
The authors conduct a review of SCM literature, including supply chain strategy, supply chain integration (SCI), agile and responsive supply chain and SCM for innovative and fast-changing industries. The authors develop a conceptual model and a decision-making framework and use four mini cases to provide support for the model and framework.
Findings
The FEI, characterised by a high level of innovation and differentiation, short products/services lifecycle and high variety, is yet to be fully defined. Inherent uncertainty in FEI supply systems makes SCM in these industries a complex but strategic task for their managers. The framework and the model offered in this study, which employ a core competency concept and provide risk management strategies, offer a strategic tool for managers and scholars in the field to optimise their integration strategies and to operationalise integration decisions.
Originality/value
Little research has been published on transferable and cross-industrial SCM in FEIs. This paper defines the FEI and its resource-related concerns and then offers a conceptual model and a strategic decision-making framework for SCI in FEIs.

Abstract
Purpose
The purpose of this paper is to investigate and understand the differences that exist between educational institutions in the methods and practices employed in the development and implementation of Lean projects. Whilst many Higher Education Institutions (HEIs) are now starting their journey towards effectively implementing Lean, Further Education Institutions (FEIs) have treaded this well worn path many years previously and so the aim of this paper is to find what key features and issues FEIs have put in place to assist them in implementing Lean projects and whether HEIs can learn from such institutions.
Design/methodology/approach
The paper applies two research methods in an attempt to understand the differences between the institutions and hence understand the key features that can be used to better implement Lean initiatives. First, through a series of focus groups, the authors employ a low-level form of Group Consensus Theory in an attempt to understand the organisational dynamics surrounding the adoption of Lean. This is used to understand whether Lean improvement teams within FEIs implement such initiatives with the autonomy and support from senior management. Second, the same group members, detailed interviews were held in order to identify further and more specific information around the tools and techniques employed in the implementation of Lean initiatives in both HEI and FEIs.
Findings
The study found that although FEIs had much more experience in the design, development and implementation of Lean initiatives, the organisational infrastructure and dynamics towards driving Lean in FEIs was less well embedded in to the culture of the respective institutions than first thought and, that Lean had been developed and driven initially by a consultancy-based approach and around a tool-driven mentality. It was seen that whilst HEIs were generally slower in getting off the mark, there seemed to be more enthusiasm and willingness to drive such initiatives forward and in a more systematic and holistic manner even though some of the projects were in their very early stages of implementation.
Research limitations/implications
Whilst this work provides key information on how Lean initiatives are implemented across different institution types, the work has only looked at a very small sample of two teaching focused HEI and two FEIs. The work will need to be extended much more widely to incorporate a larger set of HEIs (both research and teaching focused) in order to provide a more complete map of Lean development in HEIs.
Practical implications
The aim of the paper is to provide Lean project leaders in HEIs with some additional key insights towards the cultural and organisation dynamics that exist in educational institutions other than HEIs in order to assist them in developing further and more comprehensive Lean programmes.
Originality/value
This paper is the first of its kind to study the organisational and cultural dynamics that exist between differing educational institutions in their approaches towards the implementation of Lean and business improvement programmes. The key features highlighted in this work raise important issues regarding the need and importance of developing team dynamics around project implementation.

Abstract
Purpose
The traditional front‐end‐of‐innovation (FEI) research and requirements engineering (RE) in software development have realized the opportunities for overall innovation process improvements by focusing on improving the front‐end activities. The purpose of this paper is to investigate and compare the managerial perceptions on the similarities and differences in the FEI concepts between software industry and the traditional industrial sector.
Design/methodology/approach
The research approach of this paper can be categorized as a case study. Causal cognitive maps are used as graphic tools for collecting and analyzing the perceptions of selected experts about the concepts of FEI, and for recognizing the perceived interrelationships between these concepts.
Findings
The paper presents the similarities and differences in the FEI concepts between the two industries. The most similarly assessed concept is that the quality of a product or software development project can be most often influenced by successful execution of detailed customer needs analysis.
Research limitations/implications
The selection of a purely academic interview group representing the traditional industrial sector has some limitations.
Practical implications
This paper provides viewpoints to managers and project team members on the most important factors in their front‐end activities influencing the success of product or software development projects.
Originality/value
The intersection between FEI and RE and its handling by causal cognitive mapping is a novel territory in academic research. In addition, this paper opens up a new strand for academic discussion by connecting these two domains previously unconnected in literature.

Abstract
This article provides a historical literature review and exploratory descriptive case study of one U.S. Federal agencyʼs efforts to design an appropriate government-wide leadership development curriculum for incumbent top or senior civil servants. The U.S. Federal Executive Institute was founded in 1968, it spans the 20th and 21st centuries, it illustrates changes in the compact that exists between government and its top civil servants over time, and it illustrates challenges this agency confronts addressing the task of interagency leadership development. The main findings are three continuities and three discontinuities between curriculum development then and now. Conclusions outline issues for future interdisciplinary research to inform the intellectual roots for 21st century curricula aligned to emerging roles and the challenges top career executives actually confront.

Abstract
Purpose
The purpose of this study is to investigate the performance of fire protective materials in protecting steel section. A new indexing system is introduced, named as fire endurance index (FEI), which can be used to evaluate the performance of fire protective materials.
Design/methodology/approach
In this study, experiments were carried out using W4 × 13 steel section. Eight samples were prepared; one was a bare steel section without any coating material, and seven were prepared using four types of materials such as vermiculite-gypsum plaster, gypsum plaster, concrete cover and glass wool-concrete cover for fireproofing of the sections. An enclosed electric coiled furnace was used for heating the samples for a certain period. The duration of protection was determined, and the FEI of the materials was calculated. The higher the index value is, the better the performance.
Findings
The results demonstrate that the glass-wool-concrete cover offered the best performance at high temperature among the four types of materials. In the experiment with glass-wool-concrete cover, the furnace temperature reached 750°C, whereas the steel temperature reached only 100°C. The FEI of the coatings were calculated. Among the eight samples, glass wool-concrete cover also achieved the highest index value.
Research limitations/implications
The experimental work was performed using a limited number of specimens. Furthermore, the robustness of the indexing system needs to be evaluated with other materials and a wide range of heating rate and temperature. This study sets the foundation for future work.
Practical implications
The findings of this research may contribute to a better understanding of the performance of the materials used as fire protective coatings. This might be helpful for the researchers and practitioners in their design and implementation of legislation of fire safety codes.
Social implications
Understanding the performance of the fire protective coatings will help in evaluating the fire resistance capabilities of the materials to use for the structural steel members, which may protect collapses and disasters of buildings.
Originality/value
This paper deals with the performance of four types of materials, that can be used as fire protective coatings for structural steel members. Furthermore, the FEI explicitly indicated their performance with numerical values. In this study, the heating of the specimens was performed using a non-standard fire curve based on the concept that naturally occurring incidents of fire do not follow the standard fire curves.

Abstract
This article explores the importance of accessible and focal information in influencing beliefs and attention in a learning-to-forecast laboratory experiment where subjects are incentivized to form accurate expectations about inflation and the output gap. We consider the effects of salient and accessible forecast error information and learning on subjects’ forecasting accuracy and heuristics, and on aggregate stability. Experimental evidence indicates that, while there is considerable heterogeneity in the heuristics used, subjects’ forecasts can be best described by a constant gain learning model where subjects respond to forecast errors. Salient forecast error information reduces subjects’ overreaction to their errors and leads to greater forecast accuracy, coordination of expectations, and macroeconomic stability. The benefits of this focal information are short-lived and diminish with learning.

– The purpose of this paper is to explore the changes in managerial activities and challenges at different phases of innovative projects.
Abstract
Purpose
The purpose of this paper is to explore the changes in managerial activities and challenges at different phases of innovative projects.
Design/methodology/approach
Six NPD project managers were interviewed in three different project phases in a qualitative, longitudinal design. The resulting 18 semi-structured face-to-face interviews were content analyzed and categorized according to thematic similarity.
Findings
Altogether 19 categories describing managerial concerns in managing innovative projects were recognized. Task-oriented, rather than people-oriented, approaches were dominant throughout the projects, although the reported concerns clearly varied at each phase. The early development phase emerged as a transition point, where managers had to transform their roles, reported activities decreased, and reported challenges increased.
Research limitations/implications
Although based on a small number of participants in a single setting, the results highlight the need for longitudinal studies and differentiating between the various phases of the innovation process, as there was great variance in the concerns of each phase. Furthermore, domain expertise seemed to have a large impact on how the managers reformulated their role in transitioning from the front-end to the development phases.
Practical implications
The present study emphasizes the need to support managers in transitioning between different innovation phases and to recognize the need to adjust managerial roles. Further, it seemed crucial to establish the practices supporting successful teamwork in the front-end phase before the first phase transition.
Originality/value
The study is a rare example of a longitudinal research design examining the implications and transition between different phases of the innovation process within the same projects for project managers.

Abstract
Purpose
The purpose of this paper is to explore two dimensions of leadership practices (i.e. teaching and learning and sources of power) used by two exemplary principals in mainland China against a background of education reform and to identify how broader contextual factors have shaped these two dimensions of their leadership.
Design/methodology/approach
An exploratory case study was used that drew upon semi‐structured interviews, observations and document analysis. Interviews were conducted with two principals, six teachers from each of the two schools and a superintendent who was the supervisor of the two principals.
Findings
The findings reveal that there are some common elements in both of the leaders' practices but also some subtle differences. Both leaders emphasise teaching and learning. One sees herself as curriculum expert; the other delegate teaching responsibilities. While both uses a top down approach, one principal uses an adversarial approach and the other a more facilitative approach.
Research limitations/implications
The study used a small sample size. It explored the leaders' practices in the light of broader contextual factors rather than personal factors or gender‐based factors
Originality/value
Given the limited empirical research conducted on female principals in mainland China, this qualitative study provides insights into two dimensions of leadership used by two exemplary principals and explains their practices in the light of critical contextual factors such as contemporary and traditional Chinese culture and the school's organisational context.

Abstract
Purpose
This paper aims to reasonably quantify the radial deformation of turbine blade from a probabilistic design perspective. A probabilistic design for turbine blade radial deformation considering non-linear dynamic influences can quantify risk and thus control blade tip clearance to further develop the high performance and high reliability of aeroengine. Moreover, the need for a cost-effective design has resulted in the development of probabilistic design method with high computational efficiency and accuracy to quantify the effects of these uncertainties.
Design/methodology/approach
An extremum response surface method-based support vector machine (SVM-ERSM) was proposed based on SVM of regression to improve the computational efficiency and precision of blade radial deformation dynamic probabilistic design regarding non-linear material properties and dynamically thermal and mechanical loads.
Findings
Through the example calculation and comparison of methods, the results show that the blade radial deformation reaches at the maximum at t = 180 s; the probabilistic distribution and inverse probabilistic features of output parameters and the major factors (rotor speed and gas temperature) are gained; besides, the SVM-ERSM holds high computational efficiency and precision in the non-linear dynamic probabilistic design of aeroengine typical components.
Practical implications
The present efforts provide a method to design turbine besides other aeroengine components considering dynamic and non-linear factors base on probabilistic design for further research.
Social implications
Moreover, the present study provides a way to design dynamic (motion) structures from a probabilistic perspective.
Originality/value
It is proved that the dynamic probabilistic design-based SVM-ERSM could produce a more reasonable blade radial deformation while maintaining low failure probability, as well as offer a useful reference for blade-tip clearance control and a promising insight to the optimal design of aeroengine typical components.
