This research aims to create a methodology that integrates optimization techniques into preliminary cost estimates and predicts the impacts of design alternatives of steel pedestrian bridges (SPBs). The cost estimation process uses two main parameters, but the main goal is to create a cost estimation model.

This study explores a flexible model design that uses computing capabilities for decision-making. Using cost optimization techniques, the model can select an optimal pedestrian bridge system based on multiple criteria that may change independently. This research focuses on four types of SPB systems prevalent in Egypt and worldwide. The study also suggests developing a computerized cost and weight optimization model that enables decision-makers to select the optimal system for SPBs in keeping up with the criteria established for that system.

In this paper, the authors developed an optimization model for cost estimates of SPBs. The model considers two main parameters: weight and cost. The main contribution of this study based on a parametric study is to propose an approach that enables structural engineers and designers to select the optimum system for SPBs.

The implications of this research from a practical perspective are that the study outlines a feasible approach to develop a computerized model that utilizes the capabilities of computing for quick cost optimization that enables decision-makers to select the optimal system for four common SPBs based on multiple criteria that may change independently and in concert with cost optimization during the preliminary design stage.

The model can choose an optimal system for SPBs based on multiple criteria that may change independently and in concert with cost optimization. The resulting optimization model can forecast the optimum cost of the SPBs for different structural spans and road spans based on local unit costs of materials cost of steel structures, fabrication, erection and painting works.

The authors developed a computerized model that uses spreadsheet software's capabilities for cost optimization, enabling decision-makers to select the optimal system for SPBs meeting the criteria established for such a system. Based on structural characteristics and material unit costs, this study shows that using the optimization model for estimating the total direct cost of SPB systems, the project cost can be accurately predicted based on the conceptual design status, and positive prediction outcomes are achieved.

As a strand in industrialization movement in architecture, engineering and construction (AEC) industry, prefabricated construction (PC) has gained widespread popularity due to high efficiency, energy saving, low environmental impacts, safety and other advantages of PC. Well-managed supply chain can further leverage the advantages of PC. However, there is a lack of more systematically overview of the prefabricated construction supply chain (PCSC). This paper aims to comb the current status and look into the future direction of PCSC by reviewing the existing research.

3D printing has been warmly welcomed by clothing enterprises for its customization capacity in recent years. However, such clothing enterprises have to face the digital transformation challenges brought by 3D printing. Since the business model is a competitive weapon for modern enterprises, there is a research gap between business model innovation and digital transformation challenges for 3D-printing garment enterprises. The aim of the paper is to innovate a new business model for 3D-printing garment enterprises in digital transformation.

A business model innovation canvas (BMIC), a new method for business model innovation, is used to innovate a new 3D-printing clothing enterprises business model in the context of digital transformation. The business model canvas (BMC) method is adopted to illustrate the new business model. The business model ecosystem is used to design the operating architecture and mechanism of the new business model.

First, 3D-printing clothing enterprises are facing digital transformation, and they urgently need to innovate new business models. Second, mass customization and distributed manufacturing are important ways of solving the business model problems faced by 3D-printing clothing enterprises in the process of digital transformation. Third, BMIC has proven to be an effective tool for business model innovation.

The new mass deep customization-distributed manufacturing (MDC-DM) business model is universal. As such, it can provide an important theoretical reference for other scholars to study similar problems. The digital transformation background is taken into account in the process of business model innovation. Therefore, this is the first hybrid research that has been focused on 3D printing, garment enterprises, digital transformation and business model innovation. On the other hand, business model innovation is a type of exploratory research, which means that the MDC-DM business model’s application effect cannot be immediately observed and requires further verification in the future.

The new business model MDC-DM is not only applicable to 3D-printing garment enterprises but also to some other enterprises that are either using or will use 3D printing to enhance their core competitiveness.

A new business model, MDC-DM, is created through BMIC, which allows 3D-printing garment enterprises to meet the challenges of digital transformation. In addition, the original canvas of the MDC-DM business model is designed using BMC. Moreover, the ecosystem of the MDC-DM business model is constructed, and its operation mechanisms are comprehensively designed.

This case study will allow students to learn about effective segmentation and how to choose an appropriate segment, analyse the attractiveness of the target market by using five-forces analysis and explore business growth alternatives by using Ansoff’s growth matrix.

The Left-Out Store was an online shop that sold products exclusively for left-handers. Maitri Wadher, the proprietor of the store, being a left-handed person and driven by her childhood experiences, started the store to help left-handed people find products for their use. She started the online-only store in September 2018, and in October 2022, she found that, despite the COVID-19 pandemic having abated, her store had not grown as expected. How, then, should she push for growth? Was the niche segment substantial enough? Was her target market attractive? Should she penetrate the market or go for market development? What should she do?

To understand how certain cultural dynamics play out in the case, the main attributes of Hofstede and Meyer’s work are first highlight. While Hofstede focuses on national culture, Meyer’s uses culture as a tool by which to gauge behavior within organizations, teams and individuals. Below the main elements of their work are highlighted. Hofstede’s cultural dimensions are detailed in IM Exhibit 1. Note there are six dimensions on a scale of 0–100. The higher the number, the higher that element of that dimension. For example, the individualism score for the USA is 91, whereas China’s score is 20, suggesting that Americans are much more individualistic, whereas the Chinese are much more collectivist. Students can find where the USA, France and China, the three countries discussed in the case, stand at the Hofstede’s website noted below. For reference, these are also noted in IM Exhibit 2.

All of the information in the case was gathered using publicly available secondary sources (i.e. news articles, annual reports and executive/employee interviews). All sources are cited at the end of the Case/IM.

On April 12, 2022, LVMH Moet Hennessy Louis Vuitton (LVMH), the global leader in the personal luxury goods, released first quarter earnings for 2022, highlighting their latest acquisition, the New York City-based Tiffany & Co (Tiffany). Tiffany had performed well due to growth in demand in the USA following two difficult years because of the global COVID-19 pandemic. This underscored the fact that Tiffany was still largely dependent on the US market, which was a cause for concern for CEO, Anthony Ledru, who was brought in by the parent LVMH to elevate Tiffany and exploit the high growth market for personal luxury goods in China and other parts of Asia-Pacific. LVMH’s acquisition of Tiffany had been completed on January 7, 2021, and LVMH was expecting the turnaround of the largely US-centric Tiffany to show results by shifting focus to higher-end and more iconic jewelry lines and greater expansion in China. Nonetheless, Ledru’s ability to address the China market for Tiffany was constrained by culture clashes between the company’s French owners and management team and its large cadre of US-based employees. Employees chaffed at what they felt was a rigid and autocratic management style and at the company’s insistence on limits to a work-from-home policy that was instituted in early 2020 because of the pandemic. Ledru and his top management team had to quickly overcome the internal clashes and employee issues to make significant inroads in the China market.

This case is appropriate for undergraduate and MBA courses addressing dynamics of global business, strategy and culture, such as cross-cultural management, international business, global strategy and organizational behavior. At both levels, its is found that the case will be valuable in generating a lively discussion on organizational and strategic challenges grounded in often lesser discussed issues around cultural fit. In most courses, the case should be positioned toward the end, mainly because it examines both cultural challenges (French ownership of a quintessentially American company) and strategic initiatives (how to grow the brand itself along with geographic expansion, i.e. China), assuming that the module has covered one or the other/or both at different points in the course.
