Process as prototype: exploring complex knowledge exchange in the production of low-cost buoyancy aids in Zanzibar through the participatory design of a ‘workflow system’

This paper reports on an investigation into the role of experiential knowledge in growing capacity for producing low-cost buoyancy aids with soft goods manufacturers – tailors – in Zanzibar, set within complex knowledge exchange collaborations under academic-industry partnerships. In this study, the makers' practice of tailoring and their local environment knowledge had a formative role in designing a prototype ‘workflow system’ for local, small-batch production of low-cost rescue throwlines as part of a wider community-led water safety programme.

The study builds on a previous phase of the research that identified limitations with a human-centred design (HCD) approach to the creation of opensource instruction manuals for low volume production of rescue throwlines. We propose that the previously incumbent HCD approach through its problem-solving procedures obscured the importance of the local makers’ participation in the problematisation of the manufacturing process. By foregrounding the local makers’ knowledge of the whole manufacturing process, from sourcing materials in the market to making and testing the products, this study aimed to investigate how the local makers would devise and develop their own methodological approach to making the rescue throwline, examine what the findings would suggest for the design of the throwline, and explore how this knowledge might be exchanged with other collaborators in the project. A further and longer-term aim is to support the development and impact of local capacity building in end-to-end drowning prevention management by demonstrating the importance of experiential knowledge in existing local communities of makers.

A participatory making approach informed by design thinking underpinned the design of the study. An experimental participant-led approach to the generation of data draws attention to the different positions and types of knowledge negotiated. The study elucidates some of the barriers for exchanging this critical experiential knowledge with collaborators and exposes challenges for creating new social infrastructure within the community concerning drowning prevention. It concludes that managing complex knowledge exchange in prototyping in the Zanzibar context requires an iterative methodological approach to the co-construction of knowledge centred around the experiential knowledge and skills of the users of the ‘workflow system’.
