Three things I keep coming back to

I love reading and collecting quotes. These feel right for right now.

Dieter Rams
"You cannot understand good design if you don't understand people; design is made for people."
Bill Campbell
"Leadership is not about putting greatness into people — it's about recognising the greatness that's already there and creating an environment where it can emerge."
Alan Cooper
"If we want users to like our software, we should design it to behave like a likable person: respectful, generous and helpful."

What I believe in when managing people

Meaning
& Purpose

Everyone should find meaning in the work they do. Meaning comes from understanding what you are doing, the problem you are helping to solve, the business need you are adding value to and what's in it for the customer.

The result is purpose. The team will feel they are contributing, that the work matters, that they can see the bigger picture. They will feel happier and fulfilled.

This is where I spend a lot of my energy as a manager making sure the team has context, not just tasks. Vision sets the direction. Direction is more important than speed.

Foster Curiosity
The desire to learn new things, have new experiences, meet new people. Curiosity is the engine that keeps a team from going stale.
Be Authentic
Be honest, transparent, present and genuine. People can feel when you mean it and when you don't.
Operate with Integrity
Have high standards. Integrity is the only path where you'll never get lost.
Be Decisive
People like to know what they'll have to do and when. Communicate what is important and what isn't.
Project Optimism
Optimism can inspire people. It's a choice, and one that compounds across a team over time.
Have a Good Laugh
"A day without laughter is a day wasted." — Chaplin.

Feedback I've received

What colleagues and collaborators have said.

"Flavio is a person full of passion, knowledgeable and funny. He is brave and persistent. He has strong empathy and really cares about the customer's experience."
"You encourage people to do what they love and provide them with the right environment to express their creativity. There's no such thing as micro-management with you."
"You protect us, your team. I know I can come to you with any challenge, no matter when or what it is, and you will listen, advise and support."
"The amount of effort you put into making sure those around you know where they stand, what to focus on, and how to get there is simply amazing."
"Flavio has a wonderful skill whereby he can listen to what people have to say, and only speak when he has something meaningful to contribute. I wish more people did this."
"Your ability to bridge the gap between detailed work and overall strategy really helps the team stay focused and motivated. Strategy can be ambiguous — when you present it, it just makes sense."

Seems boring, but I find joy in

01
Hiring

I like to balance a mix of questions about who they are as a person, as well as professionally. I try, through the conversation, to figure out if the candidate is a good fit for the team and the overall culture of the company.

Questions I love to ask
What brings you joy in life?
What are your superpowers?
What's the best advice you received?
What gets you excited about UX?
Why do you want to work for our company?
What is it that you love about the work you do?
02
End-of-year reviews

It's a celebration of the past year and a conversation about personal development, salary increase, bonus and career progression. Very special for both myself and my direct reports. Tough conversations happen too — but always with the certainty that I care about them personally.

Questions we learned the most with
When do you see me at my best? What are my strengths?
What are one or two things I did well? What would you like to see me doing in the future?
What is the one thing I should consider improving?

Case Study

1 million calls in a week is an expensive problem to have.

How a contact-centre crisis became a design vision — and what "great" looked like.

When Paramount+ launched on Sky Marketplace, we knew the account-linking journey had friction. Customers had to jump from TV → mobile → TV. Research had flagged the risk. The business accepted it due to contractual timelines. Then one million calls arrived in a single week.

We were already deep in the problem. Through usability tests and product analytics we mapped exactly where customers dropped off. We annotated every screen with verbatim quotes and cut a 3-minute video of the confusion triggers — so leadership could feel it, not just read about it.

Calls reduced to a couple hundred the following weeks. But it didn't stop there.

A C-level exec asked: "What does great look like?"

So we set out to find out.

We audited 18 apps to map the basic expectation for account creation and payment. We created four journey variants, each a step closer to the ideal. Our UI designer prototyped all variants in hi-fidelity, and we took them to a usability lab.

The Golden Journey — "Share and stay on TV" — outperformed everything. It validated our assumptions and confirmed it was the right design vision.

Data Guild Initiative

First you understand, then you design.

This is a love story about my relationship with data. I use it everywhere and try as much as I can to share it with everyone. For every project I've been involved in I'm always getting data from dashboards, data analysts, building relationships with key data people and self-serving.

At Sky I led an initiative called Data Guild with three purposes: support the Design team to surface data in a meaningful way; understand how to measure success across multiple areas; and align on goals.

Google Analytics Tableau Adobe Analytics
The problem with data
Data exists in every business. Most of the time teams won't consume it because it's not "translated" in a way that's meaningful to the work they do. The number one priority was to audit all the data points we were tracking and surface them in a way everyone could understand.
Connecting to what matters
We made sure everything we tracked connected to our north-star metric: NPS and CSAT. I put together a 66-page deck explaining what data we had, why it mattered, what caused CSAT to move, and every data point tracked for Entertainment OS.
Backlog prioritisation
Data also helps us calculate how much value to give a feature. Through analysis I found that one area of the interface drove 38% of viewing actions — and another contributed 0.4%. That context transforms prioritisation conversations.
Sharing the knowledge
We organised data talks by inviting the Head of Data and data analysts to share their work. The team loved it and felt energised. Data levels the playing field, removes subjectivity, and helps a business mitigate risk.
"It's really inspiring and refreshing to see designers and stakeholders making decisions based on evidence. Data levels the playing field, removes subjectivity and helps a business mitigate risks."
