Our approach
Grounded in UX research, design and business communication principles.
The work is grounded in established usability and human-centred design practice, not opinion. Three lenses are used together: real user and customer research, principle-led design evaluation, and alignment with business goals.
Real user & customer research
The work begins by discussing whether to learn from your employees, your customers, or both. Real methods are chosen together — usability testing, interviews, concept and prototype testing — and the whole process, from planning to insights, is led by Sandstone.
Principle-led design evaluation
Experience reviews and business alignment are measured against usability heuristics first set out by Jakob Nielsen and Rolf Molich in 1990, and the human-centred design process defined in ISO 9241-210: understanding the context of use, specifying requirements, producing design solutions, and evaluating them against real needs.
Business goals
The work begins with your objectives, examining how the customer experience supports them: where people struggle, where opportunities are missed and which improvements matter most, so recommendations serve both people and your business.
The principles, and why they matter
Clarity
Nothing should compete for attention that doesn’t need to. People should immediately understand what something is, who it’s for and what to do next.
Consistency
Familiar patterns are used wherever possible. Jakob’s Law holds that people spend most of their time on other products, so yours should work the way they already expect.
Usability
Important tasks stay easy to complete: system status stays visible, people stay in control, and errors are prevented before they happen.
Accessibility
Design is checked against the full range of people using it, not just the easiest case.
A structured process
Each engagement follows a double-diamond structure, the model popularised by the UK Design Council: discovering the real problem through research, defining it clearly, developing possible solutions, and delivering clear, practical recommendations.
