Why I Deleted a Feature That Took Weeks to Code


I constantly see founders struggle with the same problem: they meticulously plan features for months, ship them, and then discover that users simply don't use them. This isn't just wasted development time; it’s product clutter that eventually kills user experience.

There is a better way to operate. It’s a compressed Build-Measure-Learn cycle that swaps costly assumptions for high-confidence decisions. Watch the Youtube Video with a real example here:

The Problem: You're Operating in a Feature Mindset

The traditional approach involves planning big features (like "Zapier integration" or "Introduce AI chat") and spending a month or more designing and shipping them. By the time the feature goes live, you’ve wasted time, and you've wasted even more time waiting and hoping for adoption.

The fix is a fundamental mindset shift: Move from features to problems. You must identify the pain point first, before ever designing the solution.

My System: The Accelerated Confidence Cycle

To minimize risk and maximize confidence, we replace the long, risky development window with a fast, structured 4-week cycle:

Phase 1: Validate & Prototype (1 Week)

Instead of building a full feature, you dedicate the first week to gathering high-confidence data.

  1. Find the Problem: Start with a confirmed customer pain, not a suggestion. For our Padel App, we realized people didn't know what to do after they booked a session.
  2. Test Low-Fidelity: Create a simple prototype (no code required). For our app, this was a post-booking onboarding screen that addressed user uncertainty.
  3. The 15-Minute Interview: Show the prototype to 5-10 non-users and ask them simply, "What do you see here? What is this for?". This confirms the feature is clear and the problem is understood, all without a full day of research.

Phase 2: Build & Ship (1 Week)

Once you have confidence from your prototype, you write the code and ship the solution. Since this feature was more of a "fix" than a large addition, we skipped split-testing and focused on speed.

Phase 3: Measure & Learn (2 Weeks)

This is the most critical phase. You must quantify the business impact over a short, defined period (like two weeks).

  1. Set Your Metrics: Define the specific metric that proves the feature works. We tracked two metrics for the Padel App: The ratio of users who added the session to the calendar and the cancellation rate of booked sessions.
  2. Be Ready to Kill: After the two weeks of measuring, there are only three outcomes:
    • Keep It: If the metric improves (e.g., we reduced the cancellation rate), you keep it.
    • Improve It: If the metric gets worse, you need to adjust or kill it.
    • Kill It: If the metric doesn't change anything, you must consider removing the feature, because useless code just clutters your software.

By running this process, you gain confidence and ensure that every item you keep in your product actively contributes to your business goals. You can also run measurements simultaneously, increasing your speed.
