D - Tool

D-Tool has been created to help support New Product Development for Low Income Economies, by supporting design decisions. One of the primary methods is a product assessment spiderweb which consists of eight indicators derived from PhD research. The indicators highlight important design considerations which enable the evaluation of product concepts, product re-design and existing products. The assessment spiderweb is supported by the contextualisation cards, indicator cards, and product case study cards.

Contextualisation cards highlight factors which should be considered during the design process. These external factors influence how products are used and distributed.

Indicator cards can be used in conjunction with the product assessment spiderweb to help analyse a design. Each card has a primary question, followed by three supplementary questions. By considering and answering these questions it will facilitate informed design choices and ensure product are suitable for users.

Case study cards provide examples of best practice in the design of products for Low Income Economies. These examples are linked to the indicator cards with one case study per indicator. These cards provide a short description of a case study and reference link for find information.

Research Methodology

D-tool was developed from PhD research conducted by Dr Timothy Whitehead and supervised by Dr Mark Evans and Dr Guy Bingham. The aim was to support the design and assessment of products intended for use in Low Income Economies.

Research was carried out using a literature review, the analysis of 64 products, a survey, interviews with product designers, and a case study with a Social Enterprise in Myanmar (Burma). The data was thematically analysed and used to create a tool to guide designers and NGOs.
