Web performance testing with tools such as Google Lighthouse is a common task in software practice and research. However, variability in time-based performance measurement results is observed quickly when using the tool, even if the website has not changed. This can occur due to variability in the network, web, and client devices. In this paper, we investigated how this challenge was addressed in the existing literature. Furthermore, an experiment was conducted, highlighting how unrepresentative measurements can result from single runs; thus, researchers and practitioners are advised to run performance tests multiple times and use an aggregation value. Based on the empirical results, 5 consecutive runs using a median to aggregate results reduce variability greatly, and can be performed in a reasonable time. The study’s findings alert to p otential pitfalls when using single run-based measurement results and serve as guidelines for future use of the tool.

Performance benchmarking and performance measurement are the fundamental principles of performance enhancement in the business sector. For businesses to enhance their performance in the modern competitive world, it is fundamental to know how to measure the performance level in business that also incorporates telling how they will performance after a change has been made. In case a business improvement has been made, the performance processes have to be evaluated. Performance measurements are also fundamental in the process of doing comparisons of performance levels between corporations. The best practices within the industry are evaluated by the businesses with desirable levels of the kind of performance measures being conducted. In that regard, it is fundamental if similar businesses applied the same collection of performance metrics. In this paper, the NETIAS performance measurement framework will be applied to accomplish the mission of evaluating performances in business by producing generic collection of performance metrics, which businesses can utilize to compare and measure their organizational activities.

In the present world, there is a rapidly growing level of awareness of social and environmental activities. Consequently, a company’s profile is not substantiated purely in relation to financial issues, rather, a need for the inclusion of environmental and social perspectives arises. This is known as sustainable performance. Hence, there is a persistent need for the practice of sustainable performance measurements (SPMs). However, despite the implementation of sustainable performance in developed climes like Europe, the US and the UK, the relevance of sustainable performance is still at a low in developing societies such as Malaysia. The main purpose of this paper is to determine the critical success factors that are attributable to sustainable performance measurement practices for Malaysian electronics and electrical (E and E) companies, as their success is subject to intense scrutiny from their developed competitors, with respect to compliance with social and environmental regulations. A self-administered questionnaire survey was conducted on 217 E and E companies. The path analysis and test of the hypotheses were carried out through structural equation modelling. This study has successfully unveiled a comprehensive SPM model with unprecedented scope, stretching from factors to indicators of a SPM model for Malaysian E and E companies. The findings indicate that pressure from stakeholders and globalization are the driving forces for E and E companies to be more proactive in sustainable practices. In this context, stakeholders, especially policy makers, should play the leading political and social roles in encouraging the adoption of SPMs in developing nations. It must be noted that E and E companies are likely to transform their learning culture and technology in terms of working towards sustainable practices once they have realized the financial benefits of adopting SPMs. With these benefits, a compounding effect due to SPMs will be created among E and E companies, where excellent performance can be achieved continuously. A major limitation of this study is the adoption of the contingency theory, which is yet to have a wide application in this area of study. Meanwhile, future research can be longitudinal in nature in addition to focusing on non-profit organizations.

Performance testing of components and subsystems of buildings is a promising practice for increasing energy efficiency and closing gaps between intended and actual performance of buildings. A typical shortcoming of performance testing is the difficulty of linking a failing test to a faulty or underperforming component. Furthermore, a failing test can also be linked to a wrongly configured performance test. In this paper, we present Building Metadata Performance Testing (BuMPeT), a method that addresses this shortcoming by using building metadata models to extend performance testing with fault detection and diagnostics (FDD) capabilities. We present four different procedures that apply BuMPeT to different data sources and components. We have applied the proposed method to a case study building, located in Denmark, to test its capacity and benefits. Additionally, we use two real case scenarios to showcase examples of failing performance tests in the building, as well as discovery of causes of underperformance. Finally, to examine the limits to the benefits of the applied procedure, a detailed elaboration of a hypothetical scenario is presented. Our findings demonstrate that the method has potential and it can serve to increase the energy efficiency of a wide range of buildings.

Abstract Good sample preparation is an essential first step to almost all laboratory analytical procedures. The procedures presented are intended to stimulate interest in generic methods for performance testing of various steps in fertilizer sample preparation, including initial reduction of unground sample, grinding, and mixing. Sample reduction quality is measured by 2 types of procedures, the first using 2 sizes of glass beads for a more theoretical approach, and the second using 2 common fertilizer materials for a more empirical method. Grinding performance is measured by recovery and carryover methods, followed by particle size and uniformity estimates of the ground material. Mixing after grinding is tested by measuring time-to-blend of a segregated mixture.

Urban Consolidation

Urban consolidation centers (UCCs) are presumed to provide more efficient goods distribution in cities and lead to decreased environmental impact and energy usage. There is, however, limited knowledge as to the actual performance of UCCs, and what roles and perspectives the involved actors have in the performance measurement. The overall aim of this paper is to investigate the roles and perspectives of involved actors when estimating and evaluating the performance of UCCs. The article is based on a study of one case that evaluates the performance of a UCC involving several actors. Interviews were triangulated with documents from the case. The results showed that actors have different roles in performance measurements and even if they share a mutual interest in conducting the measurements, they did not share opinions regarding factors such as system limits or performance indicators. The study provides a deeper understanding of the importance of inter-organizational interaction when conducting performance measurements. The study provides additional insights into the roles of the actors and their perspectives in logistics performance measurement that targets energy usage and environmental impact. These aspects are seldom addressed in less complex estimations or mathematical modelling estimations.

The ability to measure performance is both fundamental to and critical in successful product development. Previous research has focused on adding new measurements, not on evaluating those currently used. The performance measurement evaluation matrix (PMEX) is a tool to evaluate the performance-measurement system based on success factors in the development of software-intensive products. Three case studies have been conducted to test the PMEX and the results indicate that the PMEX enables managers to determine explicitly what is and what is not measured. Time, cost, and quality seem to be the focus of the performance measurements while technology and planning activities are absent.
