Scrum Journey, Lessons from a Bumpy Start

Why building one flow at a time helps you catch bugs early, test better, and ship with confidence.

We recently hit an important turning point in our product development journey. We were restructuring one of our products.

We picked the horizontal approach , over vertical approach. Building out the product in layers across the stack. The idea was to get everything in place and then bring it together. Sounds good in theory. But here’s what actually happened.

When everything finally came together, we didn’t have enough time for proper integration testing. Things were sluggish, some parts buggy, and the product didn’t feel cohesive. Since no one owned the end-to-end flow, fingers started pointing. Some team members even felt personally attacked.

At that point, as a Scrum Master I chose to focus on quality over blame.

Instead of asking “Who missed what?”. We asked, “What was missing?” The goal was clear, address the gap, not the people.

The conversations that followed were honest and much needed. We spoke about the need for a mindset shift. About ownership. About defining clear responsibilities — and holding ourselves accountable.

Here are the lessons we took away:

• Build vertically: Complete one user flow first. Test it. Gather feedback. Only then expand. Read my article on Vertically splitting stories

• Test early and often: Don’t leave integration testing till the end.

• Quality matters: It’s okay to reject work if it doesn’t meet agreed standards.

• Reiterate agreements: Don’t hesitate to go back to what we committed to.

• Ask the right questions: Surface the real risks, sooner.

This wasn’t an easy moment. But it was a defining one.

We now know that how we build matters as much as what we build. And sometimes, the best lessons come wrapped in a bit of discomfort.
