Fizzy is a new Kanban tool designed for tasks ranging from vacation planning to app development. It’s the first software-as-a-service (SaaS) product from the company that is also open-source, allowing users to run and improve it. The development process involved a small team—two designers and four programmers—and followed a new approach called “new product mode,” which emphasizes speed and flexibility rather than strict timelines or predefined scopes. Instead of relying on traditional methods like betting tables or fixed cycles, the team focused on quickly proving ideas and iterating based on real-world use. The development framework used was Shape Up, but the execution differed significantly from how established products are managed. The team didn’t commit to rigid timelines; instead, they prioritized optionality, allowing them to pivot quickly when new ideas arose. For example, when building the “Stalled” feature, developer Kevin completed it in just two days, enabling immediate feedback and adjustments before launch. The approach allows for a natural rhythm in the workflow, with kickoffs and heartbeats guiding the process without strict commitments. Skipping cool-downs—time allocated for reflection and planning after a cycle—was another tactical choice. The team felt it unnecessary given the small size and dynamic nature of their project. As they moved toward a version one launch, deadlines became more critical, pushing the team to make decisions and uphold higher standards. While this method can lead to pitfalls, the team’s experience with Shape Up gives them the intuition needed to navigate potential challenges effectively.
