Backward Planning Glossary: 12 Terms Explained

TL;DR: Backward planning (also called backcasting or reverse goal setting) means starting at your goal and working in reverse to identify every prerequisite step. Key terms include dependency tree (the visual structure of those steps), milestone (a major checkpoint), tree action (a GoalBranch operation like expanding a branch), and goal expectancy (a measure from a 2017 study showing why backward planners believe more strongly they'll succeed). Use this glossary as a quick reference when reading the other posts on this site.

This glossary defines the key terms used across GoalBranch's guides and tooling. It's a reference page, not a tutorial. Jump to any term you need.

Backward Planning

Starting at your desired outcome and working in reverse to identify every step that must happen before you reach it. Instead of asking "What should I do first?" you ask "What needs to be true right before I reach my goal?" Then repeat until you reach something you can do today. See the full guide: what backward planning is.

Backcasting / Reverse Goal Setting

Both are direct synonyms for backward planning. Backcasting is the older term, used in futures studies and urban planning since the 1970s. Reverse goal setting appears mostly in productivity writing. They all describe the same method: start at the outcome, work backward. For a full walkthrough with a forecasting comparison and a five-step exercise, see what backcasting is.

Forward Planning

Planning chronologically from today forward, the default approach most people use for to-do lists and project plans. It works well for short, known sequences (your morning routine, a weekly schedule) but tends to drift on ambitious, multi-month goals. Read the full backward vs. forward comparison for when each works best.

Dependency Tree

The visual structure GoalBranch generates from your goal. Each node represents one step, and each step is connected to the one above it: you must complete the lower node before the higher one is achievable. For example, "build a landing page" is a prerequisite for "collect email signups," which is a prerequisite for "launch to 100 users." The tree shows every dependency at once, so you never discover a missing prerequisite halfway through. A tree can expand up to six levels deep from a single goal, and you can drag nodes to rearrange the visual layout without affecting the dependency logic; the connections stay intact.

Branch / Node

GoalBranch-specific UI terms. A node is a single step in your backward plan: one concrete action or milestone. A branch is a node plus everything beneath it in the dependency tree. When you regenerate a branch, GoalBranch replaces that entire section of the tree with a new set of steps based on your feedback. This is the core interaction in the product: evaluate a branch, decide it doesn't fit, and regenerate it with different framing.

Milestone

A major checkpoint in your backward plan, usually 3-7 milestones covering the full timeline from today to the goal. A good milestone is specific and measurable, such as "$10k MRR," "300 trial signups," or "Product Hunt launch day," not vague ("get traction"). Each milestone becomes the anchor for a branch of sub-steps beneath it.

Tree Action

GoalBranch's billing unit. Every time you break a step into sub-steps, regenerate a branch, suggest alternatives, or adapt your tree, that's one tree action. The free plan includes 25 per month; Pro includes 500. For example, if a generated branch doesn't fit your approach, regenerating it with feedback like "make these steps more granular" costs one action. Tree actions reset monthly, and your trees and data are never affected if you run out. See pricing for full plan details.

Goal Expectancy

A term from the 2017 Psychological Science study (Park, Lu & Hedgcock). Goal expectancy measures how strongly someone believes they will succeed at a given goal. The study found backward planners reported higher goal expectancy than forward planners, and that this belief translated into better actual performance. For example, a participant who backward-planned a complex project felt more confident about completing it than one who planned forward, even though both had the same amount of work ahead. Read the study: Relative Effects of Forward and Backward Planning on Goal Pursuit.

Direction Drift

The failure mode where forward plans gradually wander from the original goal. Each day's tasks feel locally urgent (reply to that email, tweak that design, attend that meeting) but none of them move toward the outcome you actually wanted. Backward planning prevents drift because every step is derived from the goal, not from today's inbox. If a task doesn't appear in the backward tree, it doesn't belong in your week.

Goal Decomposition

The general concept of breaking a large goal into smaller sub-goals. It's the fundamental operation behind every planning method, not just backward planning. Forward planners decompose by time ("what can I do this week?"); backward planners decompose by dependency ("what must be true before that milestone?"). Backward planning is one specific method of goal decomposition: the one that starts at the outcome rather than at today.
