It started with a phone call late on a Thursday. "We're bleeding money on support. Customers are churning. And that monolith is held together with duct tape and prayer. Can you help?". As a solution architect, this is the moment the real work begins. The system in question was a 15-year-old CRM built in a now-defunct framework, with business logic buried so deep even the original developers would need breadcrumbs to find their way back. But a full rewrite was off the table. Too risky, too slow. They needed a change that was incremental, controlled, and safe. That’s when we reached for a proven technique: the Strangler Fig Pattern.

A solution architect at a mid-sized fintech startup was wrapping up a Friday afternoon design review when an alert came in. The customer onboarding API was intermittently failing. Not enough to trigger a full incident, but enough to raise eyebrows in the compliance team. At the root of the problem? A background verification callout to a third-party KYC (Know Your Customer) service. When that service hiccupped, the onboarding flow stalled. And because it was a synchronous call in a tightly coupled microservice, retries weren’t consistent. Worse, the core service logs showed nothing. The failures were silent.

It was 08:47 AM. A coffee-fueled stand-up in a hybrid team where microservices were meant to be the new golden standard. Yet, a nagging pattern kept surfacing: services were tightly coupled, boundaries misaligned, and ownership blurred. The architecture diagram said one thing, but Jira tickets, team handoffs, and production logs told another.

“How do we know the architecture is still good?”I remember the question clearly. It was halfway through a large-scale microservices migration at a fintech I was consulting for. The CIO asked it in a steering meeting, eyes scanning the room. Silence. Until one engineer muttered, “We hope so…”. That moment stuck with me. It echoed a deeper truth: without feedback loops, architecture drifts. The elegant diagrams fade, entropy creeps in, and assumptions go stale. That’s when I started embedding Architecture Fitness Functions into every significant architecture I touched.

It was day one of a new strategic initiative at a European telco. The CIO had called us in a cross-functional team of enterprise and solution architects to "make sense" of the business transformation underway. The ask? Launch a new B2B digital marketplace within 12 months, tightly integrated with legacy billing and CRM systems. Before diving into cloud-native platforms, APIs, or integration middleware, we had to do the architect's equivalent of checking the map: define the baseline and target business architectures, and more importantly, identify the gaps.

The crisis didn’t start with a breach. It started with a routine audit. For the lead architect, the previous months had been spent immersed in crafting what felt like their most elegant solution yet. A new customer engagement platform, fully containerized, multi-region, API-driven, scalable to millions. They had solved for failover. They had solved for latency. They had modeled domain boundaries down to the bounded context. It was, on paper, nearly flawless.

Picture a soccer team stepping onto the field, full of talent and energy, but without a playbook. Everyone has their own idea of what the next move should be. Chaos ensues. There are moments of brilliance, but no consistency, no strategy, and ultimately, no win. This is what enterprise transformation looks like without architecture principles. These principles are not just corporate buzzwords or procedural fluff. They are your playbook, the guiding strategies that help every part of your organization move in sync toward a common goal.

It started like any other digital transformation project: a multinational client, a tight deadline, and the excitement of architecting a greenfield platform in the cloud. We had microservices humming in Kubernetes, event streams flying through Kafka, and pipelines buzzing in CI/CD. Security? Of course, we had it: identity via OpenID Connect, TLS everywhere, secrets in Vault. We had checked the boxes.

A colleague asked why we had chosen Kafka over RabbitMQ for a specific integration layer we implemented last year. I paused. I knew the choice had been debated, analyzed, and agreed upon in one of our architecture review sessions. But the details? The trade-offs? The alternative paths we explored and the final rationale? They had slipped into the fog. I found myself wishing we had a simple, structured way to capture architectural decisions as they happened, not just the what, but the why, and even the what-we-left-behind. That’s when I stumbled upon Architecture Decision Records, or ADRs.

It always started the same way: Bold visions, ambitious strategies, and the promise of seamless digital transformation. Yet, within a year, enterprise architecture efforts would crumble into fragmented systems, unchecked technical debt, and a battle between IT and business leaders. The reason? A lack of governance.

Imagine you’re a kid again, holding a red plastic View-Master in your hands. You pop in a reel, click the lever, and like magic, a new scene appears. Each click gives you a different perspective: Scooby Doo, dinosaurs, the Grand Canyon, space adventures. The magic lies not in the toy itself, but in how it delivers views tailored to your curiosity.

Every solution architect knows that systems aren't the only things with dependencies, people are too. The APIs we integrate are predictable. Stakeholders? Not so much. You're mapping domains, aligning systems to business capabilities, wrestling with legacy constraints, and just when you think you've nailed the architecture, a sponsor with high power and low interest torpedoes your roadmap with a casual "I don't see the value."
