But that’s exactly what happened during David Stubberfield’s talk!
Director and Principal Consultant at Carter Consultancy, David, took to the stage with a humble prop, a slide filled with various shades of tea and delivered a masterclass on process improvement, customer satisfaction, and brand identity. Through the disarmingly simple metaphor of making a cup of tea, he brought to life some of the most critical challenges and opportunities facing businesses today.
It all starts with the brew
“Can you see your perfect cup of tea on this chart?” he asked the room. Some chuckled, others shouted out preferences such as A2, D4, milky, strong, green, peppermint. That was his point: everyone likes their tea a little differently.
The process may seem universal: boil water, drop a teabag in a mug, add milk or sugar, but we all make it our own. And just like making tea, businesses develop quirks, shortcuts and habits in how they serve their customers. These differences, David explained, are your brand, your systems, and your people in action.
David went on to explain that the point of all of this tea talk is that “if you want consistent quality, loyalty, and growth, then you need to understand your ingredients, standardise your process, and get the delivery right.”
The transformation triumvirate
David’s framework, what he calls the transformation triumvirate, consists of:
- Continuous Improvement
- Customer Experience
- Change Management
Miss any one of these, and your transformation risks falling flat. “You can’t improve what you don’t measure,” he noted, “and you can’t implement change if you’re not bringing people with you.”
He spoke passionately about real-life client stories, from reducing costs by over £7 million across businesses to helping one team increase customer retention by 29% and employee engagement by 26%. These weren’t hypothetical models; they were results and came from small changes done well over time.
Brand identity starts with the basics
Much like how Costa’s switch in milk providers caused a stir among loyal customers, David reminded us that small details matter. “A dirty delivery van affects how people view your brand,” he said. “Even if the product inside is flawless.”
Branding isn’t just the logo or the tone of voice; it’s how you consistently make people feel. We learned that consistency stems from aligning processes, systems, and people with one clear vision.
“Imagine being served tea in a paper cup at the Ritz…”
That one line brought laughter and a few winces from the audience. It perfectly captured how expectations and delivery must be aligned. It’s not just about what you serve, it’s how you serve it. “We all carry emotional black boxes,” David shared. “If you catch your customer in a bad mood and then deliver a poor experience, that moment could be your last chance.”
He challenged the audience to think about their businesses not from the inside out, but from the outside in. What do customers actually experience? And more importantly, how does it make them feel?
Don’t skip the human element
While David’s session covered data, systems, feedback loops, and KPIs, it always came back to the human element. “Employee engagement is critical,” he stressed. “Empowered employees fix processes, improve experiences, and embody your brand.”
Without that human touch, even the best strategies will fall flat. And that, he reminded us, is where many change initiatives fail. “Only 34% of change programmes succeed, often because leadership fails to back them properly.”
So, what’s the tea got to do with it?
Everything! The tea was the metaphor, but the message was transformation.
David asked everyone in the room to consider:
- When did you last revisit your processes?
- Are your KPIs measuring what really matters?
- How often do you seek feedback? Not just from customers, but your team?
- Do your values align with your brand experience?
- What one change could you start with today?
And most memorably, he closed with this:
“Rome wasn’t built in a day. Continuous improvement is a stair-step model. Take one step. Then another. Then another. That’s how transformation happens.”
The tea might have been PG Tips, but the insight was anything but basic. It was one of the most grounded, practical, and surprisingly moving talks of the day and a powerful reminder that growth isn’t about grand gestures. It’s about knowing your brew, getting the process right, and showing up with consistency and care… cup after cup.
