  • Finding the Joy of Building Again

    I haven’t written serious code in almost ten years. Not because I stopped caring about software. I moved into leadership, into strategy, into the kind of work where your output is measured in decisions made and teams unblocked rather than commits pushed. The tools changed. The muscle memory faded. The…

  • The Cost of Compromise

    We talk about compromise as though it is a virtue. The reasonable person finds the middle ground. The mature leader gives a little to get a little. The wise professional picks their battles. But nobody talks about what gets left on the table every time you do. Compromise has a…

  • 12 Biases that lead to bad decisions

    1. Loss Aversion What it is: We feel the pain of losing something roughly twice as intensely as the pleasure of gaining something of equal value. This asymmetry drives irrational risk-avoidance. How it manifests: Leaders hold on to failing projects, underperforming staff, or bad investments far longer than they should…

  • The CISO Evolution: From Firewall Manager to Culture Architect

    There’s a phrase making the rounds in security leadership circles right now that deserves more attention than it gets: “Cyber is 20% technology and 80% behaviour.” It sounds almost heretical from a profession built on firewalls, SIEMs, and zero-trust architectures. But the most respected CISOs in 2026 aren’t saying it to…

  • Your next direct report might be an AI agent. Are you ready to manage it?

    Something shifted quietly in the past few months, and most leaders have not yet caught up with what it means. AI agents are no longer a concept on a roadmap. They are being deployed into real workflows right now — triaging requests, updating records, drafting proposals, routing decisions, executing multi-step…

  • The hidden cost of AI productivity: we’re skipping the part where people actually learn

    Every organisation celebrating its AI productivity gains is also, quietly, depriving its junior people of the experiences that make them leaders. Nobody is talking about this yet. But they will. Here is what is happening. AI is extraordinarily good at handling the messy, repetitive, lower-order work — the drafting, the…

  • Marginal gains can transform team cultures

    You don’t build a great team culture in a town hall. You build it deliberate 1% improvement at a time. We tend to think culture change requires a big-bang restructure. New org charts. New leaders. A rebrand. A values reset workshop. Sometimes those things are necessary. But more often, culture…

  • Antifragile teams

    Antifragility is a word that stays with you once you truly understand it. It was introduced by Nassim Nicholas Taleb in his book Antifragile, and it challenges the way most of us think about strength. We are used to talking about resilience. A resilient system absorbs shock and returns to its original state.…

  • Reframing Cyber awareness as Digital Safety

    Phishing remains the most reliable entry point for attackers. Whether the lure is a fake invoice, a credential harvest, a business email compromise attempt, or a well-crafted impersonation, the common factor is human behaviour. A single click can bypass millions of dollars’ worth of technical controls. That is why awareness…

  • The Slow Normalisation of Mediocrity in Sri Lankan Cricket

    I grew up in Sri Lanka and played years of school cricket. I watched Sri Lanka win the 1996 World Cup and still remember the goose bumps. There was a time when the mere sight of the lion on the chest meant something. When teams didn’t just play against Sri…
