Rapid prototyping can potentially accelerate the entire process of new product development (NPD), enabling a high level of customer involvement and hence new product success (NPS). This study aims to examine the relationship between prototyping and NPS, and the moderating effect of customer involvement, as well as the influence of speed of information dissemination on customer involvement.

Data were collected using the survey method through structured questionnaires. The key participants were management and team leaders from technology-based companies.

The results indicate that prototyping positively correlates with NPS, particularly when customer involvement is high. The speed of information dissemination, both from customers and on competitive products, has a positive impact on customer involvement.

The study was limited by the undefined development stage of the prototype when offered for customer feedback. Future studies could focus on how customer involvement at each stage of prototype development affects NPS through a moderating effect.

The study confirms that investing in prototyping equipment for NPD increases the probability of NPS. Information capturing customers’ views and on competitive products in the market should be shared among the NPD teams. This could encourage better sharing of opinions and perceptions with customers about whether new products meet their wishes and expectations.

This study demonstrates that customer involvement moderates the relationship between prototyping and NPS. The degree of customer involvement depended on the speed of response of the customers themselves and on how well competitive product information was disseminated within the NPD team.

To examine the service performance of a number of internet retailers and to identify differences (if any) in internet retailers' service performance across a series of attributes based on consumers' assessments.

To compare the perceived service performance across internet retailers with respect to several areas: core service performance, web site features, recovery service, consumer satisfaction and intentions. A structured questionnaire was used to gather the data. The internet retailers are two budget airline retailers, a book retailer, and a multi‐channel bank.

Internet retailers' service performance was generally at an acceptable level. The variation of their online service performance was dependent on industry factors and the effectiveness of online service management. Consumers' perceptions of the internet retailers' performance were significantly different on several service attributes. However, consumer online service satisfaction levels across internet retailers were similar.

Convenience sampling and the limited number of internet retailers do not permit results to be generalised to the larger population. Future investigation with a larger sample could provide a more comprehensive coverage.

Provide useful information for internet retailers who plan to improve their service performance. This study indicated that retailers' experience from managing the physical store‐based retail service might not contribute towards their online service performance.

This paper analyses service performance of different retailers in the same industry or across industries to provide valuable indication of online service performance and attributes that contribute to differential performance levels.

This study investigates consumer purchase behavior during the steady devaluation of currency, which led to increase in inflation rates in Egypt.

This study collected and analyzed numerical data to test the causal relationships found among the research model variables. Administrated questionnaires were distributed March 2023 in cross-sectional timeframe in several visits to hypermarkets, supermarkets and grocery stores in Cairo and Alexandria, applying nonprobability sample. Structure equation model path analysis was used to test the hypotheses.

This study shows compulsive buying, sense of anxiety, value shopping, attitude toward private label, attractiveness of local brands and materialistic behaviors impact consumers' acceptance of alternative brands; compulsive buying, sense of anxiety and materialistic behaviors impact the continuance of purchasing accustomed brands.

Retailers, government and policymakers can use this study as a guide to know how consumers react during times of high prices so to provide solutions to their needs. Policymakers should take into account the findings in managing the economy.

This study shows the effect of inflation on consumer spending to contribute to the body of knowledge in literature on the factors that influence consumer behaviors. A model was developed to frame the possible manners that might surface among consumers during times of high inflation; it reflected whether compulsive buying, sense of anxiety, value shopping, attitude toward private label, attractiveness of local brands and materialistic behaviors impact consumers acceptance of alternative brands and/or the continuance of purchasing accustomed brand.
