Why Product Leaders Should Stay Current in Marketing, Not Just Technology
A CIM CPD renewal is easy to file under housekeeping. Ian Finn argues it's actually a case for something rarely said aloud: staying current in marketing discipline isn't a detour from product leadership, it's foundational to doing it well.
I renewed my Chartered Marketer status with CIM this week. My CPD for the year has been assessed and approved, and CFCIM stands confirmed for another twelve months.
It would be easy to file that under housekeeping. I think it's worth more than that.
There's a common assumption that product leadership and marketing discipline are adjacent but separate: one builds the right thing, the other tells people it exists. In my experience that's a false separation. The best product decisions I've made have drawn on marketing fundamentals as much as technical ones.
Personalisation isn't just a feature to ship. It's a discipline built on genuinely understanding audience segments, how their needs and wants differ, not just having the data infrastructure to act on them. Segmentation thinking, knowing precisely who you're building for and why each cohort differs from the next, shapes better roadmap prioritisation than usage analytics alone ever will. And audience understanding, the ability to read what a customer actually needs rather than what they say they want, is a marketing instinct I've relied on as often as any product framework.
Staying current in these disciplines, through CPD, through active practice, and simply by not letting the fundamentals atrophy, has made me a more effective product leader, not a distracted one. The two disciplines were never as separate as they're often treated.
Grateful to CIM for the annual discipline of reflection this renewal requires. It's a genuinely useful exercise: an honest account of a year's learning, rather than letting it pass unexamined. It's also a habit worth recommending to any product leader who assumes marketing rigour is someone else's job. The ability to segment audiences, target them with personalised propositions, and build a coherent go-to-market strategy is fundamental to doing product well.

Eighteen years. Five principles. One book.
- Ian Finn on Product Leadership -
I'm genuinely excited to share that my first book, 'Product Truths: Five Principles for Building Products That Work at Scale', is now out in the world.
It distils eighteen years of product leadership learnings across a range of FTSE 100 companies, three Global 500 organisations, and three UK government departments into five principles for building products that survive contact with real-world complexity — not just the ones that look good in a deck.
Writing it required the same discipline I've used as a practitioner — finding the pattern under the noise, then simplifying until only the essential structure remains. Turning that lens on my own experience has been one of the most satisfying parts of it all.
One of the quotes that opens the book, from Lewis Hatchett, is the one that actually got me to start writing it in the first place:
"Make decisions your 8-year-old self would admire, and your 80-year-old self would be proud of."
It's not a bad test for a product decision either. Finishing this book certainly felt like one of mine.
