An extensive analysis of RS measurement techniques for Ti6Al4V parts made by SLM.

Porous structures have been widely used in filtration, medical implants and aerospace field. In the filtration field, the study of permeability of the porous structures is of great importance. This paper aims to study the influence of selective laser sintering/melting (SLS/SLM) process parameters on porosity and permeability of stainless steels filters with gradient porosity (FGM).

AISI 316L stainless steel powder was used to manufacture FGM filters by varying the hatch distance while other process parameters were fixed. The relationship between porosity and permeability of such FGM filters was investigated by means of Archimedes’ and Forchheimer’s laws. The gradient of porosity was also analyzed by means of micro-computed tomography.

The results have confirmed the ability of SLS/SLM in controlling porosity of the final product by varying the hatch distance. Further, the results allow to assume that FGM filters will have particle retention capacity related to lowest porosity value (which in turn is associated with the lowest hatch distance value used), while it will work at lower pressure drops – or at higher flow rates for equal pressure drop – when compared to a filter without gradient porosity.

Some research found in recent literature has showed the relationship between SLS/SLM process parameters and permeability of stainless steel porous structures. However, this paper fulfils the need to understand the relationship between SLS/SLM process parameters, porosity and permeability behavior of functionally graded porous structures (FGM filters).

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The purpose of this paper is to propose a set of guidelines to be used for diagnosing and (re)designing organizational systems based on Hoshin Kanri – a management framework that is recognized for building the link between strategy and business execution.

A two-step approach was used in this research work. A systematic literature review (SLR) was used to find relevant references related to Hoshin Kanri that could serve as sources for recommendations. After completing the SLR, content analysis was used to define the recommendations and analyze them, deriving a set of guidelines.

A collection of recurring topics was identified through content analysis. These topics can be interpreted as central aspects for Hoshin Kanri application. Topics were eventually categorized and one guideline was developed for each one of the categories, which resulted in a total of 23 guidelines. Guidelines were grouped in two dimensions (context and process) and also according to their central aspect (organizational culture, capabilities, focus, alignment, integration and review).

Although Hoshin Kanri has been widely applied in Japan and also in large companies over the past 50 years, it is not as widely explored in research papers as other frameworks. Literature often focuses on Hoshin Kanri only as a process and not as an organization-wide holistic system. There are few empirical studies about its conceptual assumptions and practical implications and no systematization of the main aspects that ensure the effective application of Hoshin Kanri in a universal manner.

This conceptual paper presents a proposal for improving a performance measurement (PM) system implementation process based on enterprise engineering (EE) guidelines, which gives the process a sense of completeness.

This paper analyzes a well-known process for PM systems implementation organized in two phases: identifying, designing and implementing the top-level performance measures; and cascading the top-level measures and identify appropriate lower-level performance measures. The proposed improvements to the studied process derive from the EE guidelines, which establish a basis for the structure of an organizational management system, the formalization and synchronization of processes, performance expectations, exception handling and change management.

The study reveals that not all EE guidelines are covered by the analyzed process, with four of them having no evidence of being adopted: involvement of people in process design and implementation; ensuring interoperability between different systems in the information structure; addressing of all possible exceptions; coherence and consistency of semantics across all processes.

By the lens of EE guidelines, this paper advances a how-to-guide. This paper can support managers and researchers on PM system design and implementation, given the importance and relevance of EE recommendations having a consistent and well-structured procedure.

In the performance measurement and management research field, the applicability of performance measurement systems (PMS) in nonprofit organizations (NPOs) and public administration has been considered a challenge. The diversity of these organizations makes it difficult to define proper terminology and organizational characteristics. PMS evolution has not yet been able to capture all performance dimensions of a public administration and, especially for NPO considering its dynamic and multiple goals. The purpose of this paper is to provide a conceptual framework that identifies and classifies the factors that influence the design of PMSs in NPOs and public administration.

The study was developed through a systematic literature review (SLR). A set of 29 papers were intensely studied, and the results provide a multi-disciplinary and holistic set of factors.

A set of ten factors that influence the design of PMSs in NPO and public administration were found. They were categorized into three groups: factor related to purpose, stakeholders and management.

The study synthesized the literature and provided a conceptual framework of the factors that influence the design of PMSs in NPO and public administration. No individual paper collected in the SLR shows a similar organization of the factors as the present paper. The set of factors indicates the importance of this study for NPO and public administration, and how complex a PMS in an NPO and public administration can become. The conceptual model presented can further assist practitioners in developing design process observing the role that the identified factors play.

This paper aims to investigate Lean Six Sigma (LSS) in the Brazilian context, seeking to identify its main characteristics and opportunities for future research.

This study focuses on a literature review in the area of production engineering and operations management, where 104 relevant scientific publications were identified.

The results show that the most important critical success factor for integrating LSS in Brazil is top management support and commitment. LSS integration occurs predominantly in large industrial companies, being incipient in small and medium-sized enterprises. In general, there is no structured way of applying LSS. A standard framework for LSS is still lacking.

This study is limited to a sample that only comprises Brazilian scientific studies.

Professionals and practitioners can understand the evolution of LSS through practical applications and the main LSS tools used in both the industrial and services sectors. It also points out the critical success factor for the implementation of LSS. The study highlights several roadmaps for LSS implementation adopted by large and modern Brazilian automotive industries based on a robust technological base. This study also contributes to expanding the evidence base of LSS application, both in Brazil and in other countries.

Some suggestions are proposed to clarify the structure and complexity of integrated implementation of LP and SS as well as expand the LSS application in small and medium-sized enterprises. This study is the first to discuss the current situation of LSS in Brazil and provide suggestions to expand LSS in the country. Comparisons of Brazilian LSS literature review with researches of others countries are also presented.

In this study, the performance assessment of credit unions is developed, seeking to demonstrate how the content of their operations strategy is present in the structuring of unique models of organisational performance assessment. The main objective is to compare sources of knowledge through the content analysis of the service operations strategy as proposed by the literature and validated by specialists.

This research is a qualitative study that uses the knowledge of specialists to frame a performance assessment structure applied to credit unions. The research strategy is based on multicriteria analysis, and the selected techniques are based on the MCDA-C procedure, that is, the processes of structuring, evaluating and recommending improvements.

The research results provided: a data set external to the context that serves as theoretical support for the comparisons made; the structuring of 4 unique organisational performance assessment models carried out through the MCDA-C procedure; conceptual interpretation using the lens of the operations strategy in the cognitive maps of the assessment models, which identifies the operations strategy carried out; and comparison of the result models that show their uniqueness.

The comparison between the origins of knowledge is highlighted, and the demonstration of the content was proposed by the literature and by specialists to evaluate the performance in operations. This was then compared with the content constructed with credit union managers in structuring models based on the singularities of the respective contexts. The theory was compared to practice, and it was demonstrated how the content of the operations regarding the performance could be used in decision contexts.

The purpose of this research is to examine the factors that influence the design of performance measurement systems (PMSs) in nonprofit organizations (NPOs) and public administration and explore inter-relationships among these factors.

Findings resulted through the identification of design factors from the paper portfolio of a previous systematic literature review on this topic and the construction of a factor co-occurrence network for the identified factors. 

The methodology helped to determine the relationships among factors and show how these factors influence PMSs in NPOs and public administration. It also helped to demonstrate how PMSs in these organizations are different from PMSs in traditional companies because of the impact of the factors on the complexity and dynamics of NPOs and public administration. The findings and discussion contribute to the performance measurement literature on NPOs and public administration by presenting a set of design factors related to purpose, stakeholders and management.

This paper presents practical implications for managers regarding the PMS design process and shows how some design factors can be particularly related to these organizations

The design factors are particular to the organizational dynamic and should be considered by managers involved with the design (or redesign) process of performance measurement systems.

The purpose of this paper is to present a theoretical discussion about the roles that a performance measurement system should perform. The enterprises' operations systems and environments, characterized by their complexity and dynamics, are challenging the strategic operations management models.

The developed theoretical construction is based on a literature review. The measurement system is studied in the context of a strategic operations management system.

The structures, processes and spaces were the lens used to study the performance measurement system and contributed to organize the concepts in tables, that is, roles statements were created based on these guidelines. These tables synthesized and identified the main roles that the system should perform, stating their definitions and related perspectives.

The generated framework is theoretical in essence and needs to be tested, although the theoretical exercise showed a common sense around the articulated main concepts.

The understanding of the performance measurement system roles contributes to improve design, implementation and use of the performance system.

The paper's main contribution is the theoretical underpinning used to develop the performance framework. The system design approach used will enable further research into strategic performance measurement application for the design and use of such a system. Continuous improvement, organizational learning and the management of change process will be required properties for the strategic management of the operations function.
