Incorporating Global and Local Customer Needs into Early Stages of Improved Cookstove Design
by Christopher Mattson, K. McCall Barger, Kendall Thacker
Abstract: Improved cookstoves, despite their many potential benefits in the developing world, have been adopted at surprisingly low rates. In order to achieve better adoption rates, many researchers have recently emphasized the importance of more heavily focusing on user needs when designing improved cookstoves. This can be facilitated by the use of design methodologies that are tailored for a certain application. Unfortunately, methodologies intended for developed parts of the world don\'t account for the unique challenges associated with cookstove design. Current methodologies that are specialized in cookstove design primarily focus on later, more technically detailed stages of development, and don\'t provide sufficient details during earlier stages. This paper presents an early stage design methodology that has been specifically adapted to the unique challenges of improved cookstove design. This methodology highlights the most common design pitfalls that are encountered during each stage of the design process as well as provides tools and recommendations to overcome these pitfalls. To help offset any biases that may exist, a list of the most common customer needs from around the world is included. Importantly, there are needs that are both common to nearly all households (global needs), and needs that are unique to only a subset of users (local needs). This paper suggests that by following this methodology engineers are less reliant on and susceptible to their preconceived notions of what cookstove users need.

Relevance of Lifecycle Management to Smart City Development
by Ahmed Hefnawy, Abdelaziz Bouras, Chantal Cherifi
Abstract: Smart cities are complex ecosystems with interrelated systems or system of systems. Hence, management of smart cities is very important due to the big number of stakeholders, diversity of application domains, heterogeneity of data sources, and complexity of smart systems. Nevertheless, less studies have considered management aspect of smart cities compared to other technical aspects. Considering the different phases of smart city development, there is a need for comprehensive vision to manage smart city across lifecycle phases. This work proposes a smart city lifecycle-based approach which consists of two components. First, lifecycle-based representation of smart cities by adding the depth of Time as a new dimension. Second, interaction approach between lifecycle management system and IoT platforms. For this purpose, this paper examines the empirical relevance of lifecycle management to smart city development through a limited case-based survey.

Framework for improving universal design practice
by Ravindra Singh, Puneet Tandon
Abstract: Universal Designis currently being practised mainly for a limited segment of users and Specialised products. In spite of advancement in the field of Universal Design, it has not matured completely to deliver products that are designed for a wide set of users. The presently adopted approaches being divergent prohibit the generation of products meant for all user groups. In this work, Pareto analysis is used to identify the important elements, which contribute to developing true universal products. This paper proposes a framework where four key elements of universal design, i.e., functionality, usability, performance, and product attachment are identified, and their importance underlined to make the product more acceptable. Pugh selection method is used to validate the elements with the help of a case study. The framework leads to product designs that eliminate the prejudicial effect of being labelled to improve their accessibility and acceptability.
