Plan an Agile Release with a Forecast Range
Build a transparent release forecast using remaining scope, historical throughput, and explicit assumptions, then communicate a range instead of false certainty.
Define the release boundary first
A forecast needs a clear statement of what is being forecast. Identify the smallest useful release and its acceptance conditions. Separate required scope from optional improvements. If the backlog contains unresolved ideas, discovery tasks, and several sizes of delivery item, a single completion date will hide those differences. Use story slicing to make the remaining work more understandable before treating item counts as comparable evidence.
Start with a simple illustrative range
Suppose a stable team has 24 similarly sized items remaining and has recently completed between six and eight per iteration. A rough forecast suggests three to four iterations if scope, capacity, and completion rules remain comparable. This is a planning range, not a statistical confidence interval. A few observations cannot justify a claim such as “90 percent certain.” State the evidence window and avoid implying more precision than it supports.
Account for work the count does not show
Check holidays, specialist availability, external approvals, and integration constraints. A throughput calculation cannot make a supplier dependency disappear. Include release preparation and operational acceptance where those are outside the counted items. Ask whether historical completions used the same definition of finished work. The dependency mapping guide helps expose prerequisites that need their own forecast or contingency.
Update when evidence changes
Review actual completions, added scope, and new blockers at a regular cadence. Show why the range moved: scope grew, capacity fell, or a technical uncertainty was resolved. Avoid silently resetting the baseline so every update appears on track. Present choices when the required date and forecast diverge, including a smaller release or a different rollout sequence. The sponsor decision brief provides a format for those tradeoffs.
Keep the forecast separate from a target
A target expresses what the business wants. A forecast expresses what current evidence suggests. Both are useful, but confusing them encourages people to manipulate estimates. Track whether forecasts improve as uncertainty falls and whether decisions respond to them. Use the velocity guide if the team estimates in points, and avoid comparing point totals across teams. A trustworthy range is more useful than an exact date nobody believes.
