Purpose: Industry 4.0 technologies have the potential to improve the quality management performance of industrial companies. The paper analyses the influence of Industry 4.0 technologies on quality management aspects, but also the barriers that slow down the deployment of each Industry 4.0 technology and limit each impact.Design/methodology/approach: The impact of Industry 4.0 technologies on quality management aspects (QMAs) is a heterogeneous and multidimensional phenomenon dependent on the current context, a holistic multiple case study has been applied. Twenty-six case studies were carried out on eight Industry 4.0 technologies, with a minimum of two cases per technology. These cases were selected from the 168 projects presented in the four editions of the BIND 4.0 program, winner of the 14th edition of the European Enterprise Promotion Awards. The cases were selected based on a preliminary survey of 124 project managers. Subsequently, individual case and cross-case analyses for each technology were carried out. Finally, these results were confirmed by interviews with a minimum of two customers per Industry 4.0.Findings: Results show that the adoption of Industry 4.0 technologies positively affects QMAs. Specifically, the influences received by “process control” and “customer satisfaction” from all the Industry 4.0 technologies studied are medium to high. In addition, barriers from the “economic and legal” and “workers” categories exert greater influence than the barriers pertaining to “organization”, “lack of training and information” and “technology”.Research limitations/implications: The main limitation is the generalizability of the findings of qualitative studies (ergo the case study). In this sense, statistical generalizability, characteristic of a random sample, is not intended in this paper. Therefore, the use of multiple case studies has been chosen to reinforce analytical generalizations with corroborated evidence (literal replication).Practical implications: Managers interested in adopting Industry 4.0 technologies Ts should plan the implementation process to minimize the impact of these barriers and optimize the results for each stakeholder. In this sense, the barriers that concern the workers should be managed. It is the responsibility of managers to inform and explain how data will be handled, and how privacy concerns will be addressed.Social implications: It is essential to explain and convince workers about the need for a renewal of tasks. New types of jobs (i.e. the use of robots) will involve training for workers to enable their integration alongside the new technologies.Originality/value: This paper addresses two under-researched areas that are essential when defining strategies in the industrial business context. Firstly, the paper analyses the influence of each I40 T on each QMA. Secondly, it analyses the barriers to adopt that slow down the rollout of each I40 T and limits each impact.

The manuscript describes a simplified methodology with which to assess the economic level of apparent losses (ELAL) in a water utility. This economic point corresponds to the break-even point for which the marginal benefit of increasing the frequency of the apparent losses’ reduction activities equalizes the marginal cost of their implementation. For this calculation, each apparent loss component, as defined by the International Water Association, has been subdivided into two additional categories. These categories have been established depending on how periodic activities conducted by the water utility to reduce apparent losses—namely water meter replacement and customers’ connection inspections—may affect their magnitude. It has been found that the ELAL is influenced by intervention costs, the degradation rate of the accuracy of water meters and water tariffs. In addition, this work defines a set of performance indicators to benchmark the apparent loss’s performance relative to the minimum achievable and optimum levels of the losses. Finally, two case studies on how the proposed calculation should be applied have been added to the appendices.

Developing understanding of the economic value that communities ascribe to improved operations and maintenance (O&M) services has emerged as a key factor in achieving financial sustainability for rural water systems. The present study elicits household willingness to pay (WTP) for improved O&M services in eight gravity-fed water schemes in Idjwi Island (Democratic Republic of the Congo, DRC). A contingent valuation survey was implemented through an open-ended format questionnaire to 1105 heads of household and a log-linear regression model was employed to assess the factors influencing higher values. Findings show an average willingness to pay of 327 Congolese Francs (CDF) per month and 36 CDF per bucket. Results also indicate a significant WTP differential among studied schemes. The analysis of the conditioning factors reveals that the level of excludability, the participation in management meetings and the time employed in fetching water from an improved source are contingent with their WTP. The findings of this study are important for development agents trying to establish acceptable, affordable and practicable tariffs that help finance reliable rural water systems in Idjwi.

To assess the sustainability of rural gravity-fed water schemes on Idjwi Island, the association between four hypothesized drivers of sustainability – perceived sense of ownership, willingness to pay for maintenance, trust in the water committee, and household involvement in the project – and service reliability, the main outcome variable, was analyzed. Primary data were gathered through in-person surveys of 1253 user households. The results provide two significant insights. First, during the 5–10 years after implementation, in the presence of an external intervention, a lower perceived sense of ownership for the water system was associated with higher service reliability. This stands in contrast with much of the existing literature, which outlines a consistent positive association between sense of ownership and sustainability of rural water systems. Second, despite 77% of beneficiaries stating that they were willing to pay for maintenance service, such contributions were not forthcoming, due to lack of trust in the water committee. In this scenario, almost 42% of the water points are reported as non-functional, 5–10 years after completion.

For more than a decade, foreign aid-supported water interventions focusing on an increase in household private connections have been implemented in the small urban center of Wukro. However, little has been investigated about the effectiveness of these interventions in achieving equitable and inclusive access to water and sanitation for all, including the most vulnerable. With this purpose, a cross-sectional comparative analysis of service provision between the HIV-infected population (n = 199) and non-infected population (n = 199) was undertaken. Findings suggest significant inequalities regarding the primary water source, monthly expenditure in water, water consumption, and time employed to fetch water, as well as the type of toilet facility, number of users, and the time employed to access it. Results also show a reported feeling of discrimination with regard to service provision within the HIV-positive population. This study provides evidence on local-scale interventions increasing the number of household water connections but overlooking the pursuit of equity and inclusion for the most vulnerable. The study also presents recommendations on how to specifically target the needs of persons living with HIV/AIDS in order to achieve equitable and inclusive access to water and sanitation for all.
