Hey everyone,
I was asked almost this very question yesterday: "What takes so long in the dev world?" It's a perfectly fair question, especially when a feature seems simple on the surface. This morning, I read an excellent article, "Hidden complexity in software development," that I think sums up the answer beautifully, especially in its "Foundations" section.
The best way to explain it is the classic iceberg analogy. 🧊
The feature a user sees and interacts with—the button, the form, the data on the screen—is just the tiny tip of the iceberg visible above the water. The real work, the vast, hidden bulk of the project, is the massive foundation it's built upon, submerged and out of sight.
The "Happy Path" vs. The Foundation
The code for the "happy path"—the scenario where everything works perfectly—is often the smallest and easiest part to write. The time-consuming part is building the foundation that accounts for everything else.
This foundation includes:
- Error Handling: What happens if a user enters text where a number should be? What if an external API is down? What if the database doesn't respond? Building robust error handling so the app doesn't just crash is a huge, invisible part of the work.
- Security: This involves everything from user authentication (making sure you are who you say you are) to authorization (making sure you can only see your data and not someone else's). It means sanitizing every input to prevent attacks.
- Resilience and Stability: A lot of my recent "invisible updates" to Market-Viewr are perfect examples of this. Adding caching, automatic API node retries, and better logging doesn't add a new button for the user to click, but this foundational work is critical to making the app stable, fast, and usable.
- Data Management: How is the data stored? How is it backed up? What happens when the structure of the data needs to change? This is another huge piece of the puzzle.
- Deployment & Tooling: The complex process of getting the code from a developer's machine onto a live server, setting up the build process, and managing dependencies is a whole world of its own.
So, when a seemingly "simple" feature takes a week or more to build, it’s rarely the feature itself that’s taking the time. It’s the 90% of the iceberg submerged underwater that ensures the feature is secure, stable, and reliable for you to use.
