Self-Checkout: Improving Scan Accuracy Through Design

In this unique applied research study, academics and designers partnered with four of ECR’s Retailer members to immerse themselves in the self-checkout experience, understanding from the perspectives of the shopper and self-checkout supervisors, their journey from entry to exit, and their design challenges and frustrations. Whilst some Retailers have taken strong design approaches, the design-research nevertheless found SCO machines ‘plonked’ wherever they can reasonably fit, and shoppers not always sure how to use the machines or smoothly navigate the SCO environment. In response to this problem context, the design researchers adopted a human-centred design-led approach and formulated key insights to reframe the challenges at self-checkout. Then generated a range of concepts, most of which amount to sketches of possible incremental design changes that might help reduce retail losses and improve customer and staff experiences.

Research findings overall suggest that there are no silver bullet design solutions for the complex challenges faced at SCO and instead an ecosystem of low-tech and high-tech design solutions will have a role to play in reducing customer frustrations and improving flow at self-checkout. While improved machine solutions (including future capacity for AI computer vision technology) can address some existing challenges, the key takeaway from this report is to show how refreshed “design thinking” approaches and small design interventions can make a big difference. The report highlights simple design methods that can be adopted and low-tech concepts that can be adapted and tested by Retail partners to improve upon a range of local problems, suggesting improvements that take a human-centred focus. It urges Retailers to engage with design thinking to better understand design context at SCO to help improve customer experience and reduce retail losses.

Two reports have been generated for this project: this ‘full’ report contains research insights, twenty design concepts, and includes a comprehensive account of DAC’s design-led approach, methodology and crime science thinking. The second ‘short’ report covers the research insights and the design concepts. We encourage you to review these in your business, with as many functions as possible, including those on the shop floor and in the critical role of the self-checkout supervisor.
