Engineering product design and development
Published in Riadh Habash, Green Engineering, 2017
Iterative design is an approach based on a continual process of prototyping, testing, analyzing, and improving a product. Changes and modifications are carried out based on the outcomes of testing of the most recent iteration cycle. Iterative design can be used at any phase of the design process, including when the product has already been in the market and the manufacturer is aiming to improve it. Importantly, the earlier in a product’s life cycle to implement the iterative design, the more cost-effective the approach will be.
Prototyping Tools and Techniques

Iterative design involves multiple design-implement-test loops,* enabling the designer to generate different ideas and successively improve upon them. Prototypes support this goal by allowing designers to evaluate concrete representations of design ideas and select the best.
A Four-Stage Method for Optimizing and Standardizing a Crash Cart Configuration
Published in IISE Transactions on Occupational Ergonomics and Human Factors, 2018
Shaunna Milloy, Katherine Bubric
This work emphasizes the importance of involving front-line users of a crash cart in the design process from start to finish. Specifically, it is important that a group of clinical experts agree on the contents and quantities on the cart before any work is done on the design. Even if a site does not have human factors professionals available to develop recommendations for the design, human factors principles should always be incorporated into the design of the crash cart in order to mitigate human error and ensure the cart is easy to use. The current work also demonstrate the value of an iterative design process and collecting feedback at various stages of implementation. The design was refined based on feedback received from the clinical committee, usability testing, and front-line users prior to implementation. The methodology used here to develop the standardized crash cart and the template for the configuration of the crash cart, can both be adopted or adapted for use at any health care facility.
Enabling inner creativity to surface: the design of an inclusive handweaving loom to promote self-reliance, autonomy and wellbeing
Published in Behaviour & Information Technology, 2021
Annamaria Recupero, Patrizia Marti, Simone Guercio
This paper describes the human-centred design of an accessible handweaving loom for people with different disabilities. Through a series of weaving workshops, a commercial handweaving loom was modified and enriched with semi-automatic functionalities. Thanks to rapid prototyping using 3D printers, laser cutter, printed circuit boards and electronic components, the iterative design allowed us to experiment with small low-cost adaptations that were incrementally developed, tested and improved.
