The Problem
Annual leave should be
simple. It wasn't.
Annual leave booking is one of the most fundamental HR interactions a colleague has — yet it was generating disproportionate frustration, helpdesk contacts, and manager overhead at Barclays. The experience had been built around process logic rather than human logic, and it showed.
Before we could fix anything, we needed to understand precisely what was broken, for whom, and why — across three countries with very different employment contexts, cultural expectations, and technical environments.
The Approach
Research that can't be acted on isn't research — it's theatre. Every design decision in this study was made in service of producing insights that stakeholders could actually use.
— Research principle that shaped the programme design
The programme was designed as a mixed-methods study — combining quantitative scale with qualitative depth. The quantitative layer gave us statistical confidence; the qualitative layer gave us the why behind the numbers. Neither was sufficient alone.
Global reach
Three countries.
One platform.
Key Findings
What the data
actually said.
Outcomes
From data to
decisions.
Reflection
What good research
actually looks like.
The thing I'm proudest of in this study isn't the sample size or the methodology — it's that the findings changed something. Too much research gets filed. This one got presented, debated, and acted on.
That happens when you design research with the stakeholder conversation in mind from the beginning. What decision are we trying to make? What would change our minds? What format will make the findings impossible to ignore? These questions shaped every choice in the programme design.
The navigation label finding is a small but perfect example. A contested, opinion-led debate — resolved in one study. That's what evidence-based design looks like in practice.
