Myth #3: It is impossible to predict the delivery of increments

Myth #3 contends that predicting delivery in Scrumban is impossible without fixed iterations and estimations, a notion that overlooks Scrumban's robust toolkit for forecasting. In Scrumban, predictability is achieved through:

  1. Task Granularization: Instead of using story points, tasks are broken down into smaller, similarly-sized items. The team decides the granularity, whether it's about a day or half a day's worth of effort.
  2. Work in Progress (WIP) Limits: These limits help maintain a steady flow of work and highlight bottlenecks for timely intervention.
  3. Key Metrics - Throughput and Cycle Time: Throughput measures the number of items completed in a set period, while cycle time tracks how long it takes for work to move from 'in progress' to 'done'.

With a granular backlog, the team's workflow becomes visible, allowing for accurate intervention and estimation of when parts of the backlog will be completed. Throughput indicates the team's delivery capacity within a timeframe, and cycle time offers insights into the duration each task requires to reach completion.

Tip: For teams with consistent throughput, forecasting can be refined using tools like Jira's version report, which projects task completion. In Scrumban, with uniformly sized tasks, assigning a consistent value (like "1 SP" for each item) enables the generation of such predictive reports, enhancing the visibility and predictability of delivery timelines.
