Introducing Delta Board

Delta Board is a lightweight tool for running retrospectives with small teams.

Problem

This project sits at the intersection of my personal aspirations and my professional life. I manage a team of engineers, and while I try to be careful about how much time we spend in meetings, one ceremony I consistently find valuable is the retrospective.

I have run retrospectives for years. I experimented with different formats such as Six Thinking Hats and Sailboat Retrospectives, but I always came back to the simplest version: what went well and what could be improved (the delta). That simplicity works especially well with mature teams that collaborate over long periods and run retros regularly.

The challenge is that while the ritual is simple, the tools often are not. Small teams need a lightweight space to reflect together, yet many remote collaboration tools feel heavy, noisy, or overbuilt for this purpose.

Process

When I worked in the office with my team, we would sit around a table with sticky notes. Everyone would write down what went well and what could be improved, then place their notes on a whiteboard. The facilitator would group similar notes and guide the discussion.

Over time I moved to fully remote work and my team became distributed. The ritual stayed the same, but the tools changed. Some were decent, some were painful. Most added more friction than the physical setup ever did.

Delta Board started as a weekend project to recreate the simplicity of sticky notes and a whiteboard, without the weight of enterprise collaboration software. I wanted something privacy conscious, minimalist, and intentionally in the background.

The tool should support the conversation, not become the focus of it.

Benefits

I am not trying to sell the idea of retrospectives here. For me, they create a space where a team can celebrate wins, voice frustrations, and surface issues that might otherwise stay unspoken.

I keep contributions anonymous, and Delta Board does the same. This tends to lead to more honest and thoughtful input than settings where comments are tied to identities.

I see the way a team works as something flexible and continuously evolving. Retrospectives are one of the main mechanisms that shape that evolution. Over time, teams find their own balance and can focus more on solving meaningful problems, building value, growing as individuals, and enjoying the work itself.

Introducing Delta Board

Delta Board is my attempt to build a tool that respects the simplicity of the retrospective ritual. It is intentionally small in scope and opinionated in design, built around the idea that good team conversations do not need heavy software around them.

Technical details and architecture choices deserve their own section, which I will cover separately.

The project is open source on GitHub, and a small public instance is available if you want to try it out.
