Getting Things Done (GTD) is a productivity method, created by David Allen, that asks you to capture every commitment out of your head and into a trusted external system, then decide the next action for each one. The premise is that your mind works better for having ideas than for storing them. When every open loop lives in a list you actually trust, your attention is free for the work in front of you instead of the worry behind it.

GTD has stayed in print since 2001 because it solves a problem that predates any app: too many commitments, too little working memory. It does this without telling you what your goals should be, which is both its strength and its gap. This productivity guide explains the full method first, then shows where it leaves you on your own.

You will learn the five steps, the weekly review, the two-minute rule, and the Horizons of Focus. Then you will see why a capture system needs a goal layer on top of it.

Key takeaways

• GTD runs on five steps: capture, clarify, organize, reflect, and engage.

• Writing a vague commitment down as a concrete next action is what makes a list usable.

• Offloading reminders to an external tool cuts forgetting from roughly 45% to 5% in tested conditions.

• Griply links every task up a Life Area → Vision → Goal → Subgoal → Task chain, so each next action rolls up to a measurable goal.

What is GTD and why getting things done starts with capture

GTD treats your brain as a poor storage device and a good processor. Allen's fix is to move all of it into a system you check often enough to trust.

Capture works for a measurable reason. Unfinished tasks keep intruding on your thoughts, but making a concrete plan to handle them removes the intrusion before you do any work, as Masicampo and Baumeister showed in 2011. The plan itself does the calming, even before any work happens.

There is a practical reason to trust the tool over your memory. When people offload intentions to an external reminder, forgetting drops from around 45% to 5% in controlled tests. In GTD, a trusted system is the mechanism.

The five steps of getting things done

The method moves a commitment through five steps, in order. Each step has one job, and most GTD attempts fail when one is skipped.

• Capture: collect everything that has your attention into an inbox.

• Clarify: decide what each item is and whether it needs an action.

• Organize: put each action where it belongs, by project or context.

• Reflect: review your lists often enough to keep trusting them.

• Engage: pick what to do now and do it.

Clarify is where the two-minute rule lives. If an item takes less than two minutes, you do it immediately instead of filing it. Everything larger becomes a next action.

GTD also asks you to tag actions by context, the tool or place you need to act. A call list, an errands list, and an at-computer list let you act on whatever fits your current situation. Allen lays all of this out in Getting Things Done, the 2001 book that named the method.

The weekly review keeps the system trustworthy

Without a regular step back, your capture and organize lists go stale within days. The reflect step, run as a weekly review, is what keeps your lists current enough to trust. Allen structures it as getting clear, getting current, and getting creative.

You empty your inboxes, update every project and next-action list, then think ahead about what is coming. For a full walkthrough of the ritual, see what is a weekly review. A system you review weekly stays current; one you never review fills with stale items you stop trusting.

The Horizons of Focus name goals but don't make them measurable

GTD does have an altitude model. Allen's six Horizons of Focus run from ground-level actions up through projects, areas of focus, goals, vision, and purpose. The idea is that your daily next actions should ladder up to what you actually care about.

In practice the top horizons give you no concrete tools. GTD names goals as a horizon but gives you no way to make a goal measurable, no target value, and no progress you can check. Without a measurable target, a goal can't tell you whether your daily work is moving the number that matters.

GTD manages the list of next actions well but does not check whether those actions add up to anything. Building a complete system around this means pairing a capture method like GTD with a goal layer that tracks measurable progress.

Engage: choosing what to do now with goal context

The engage step is where GTD asks you to trust your judgment in the moment. You filter by context, time available, and energy, then pick. The weakness is that "important" has no anchor when no action is tied to a measurable outcome.

This is why many GTD users add time blocking on top. Scheduling a next action into a real slot forces a decision about priority that a flat list does not. The time-blocking method guide shows how to act on GTD's next actions with goal context attached, so the block you defend is the one moving a goal forward.

How Griply runs a GTD workflow with goals attached

GTD leaves the goal layer to you. In Griply the goal is a record with its own fields. Every task traces up a Life Area → Vision → Goal → Subgoal → Task/Habit chain, so a next action is never just floating on a flat list.

Capture and clarify map directly to Griply. The Inbox holds unprocessed tasks with no link, no date, and no deadline, and clarifying means giving an item a link, a date, or a deadline. Tags created inline with #newtag stand in for GTD contexts like calls or errands, the closest equivalent Griply has.

For the horizon GTD leaves aspirational, each Goal in Griply carries a metric: a start value, a target value, and progress you log over time. The Goal planner holds the measurable layer GTD describes but never builds. Today View runs your engage step with goal context, so each task on the list names the goal it serves before you decide what to do now.

Frequently asked questions

What does getting things done mean?

Getting Things Done is David Allen's productivity method built on capturing every commitment into a trusted external system, then defining the next physical action for each. The goal is a clear mind, because your attention is free once your commitments live somewhere you trust.

What are the five steps of GTD?

The five steps are capture, clarify, organize, reflect, and engage. You collect everything into an inbox, decide what each item is, file it by project or context, review your lists regularly, then choose what to act on now.

What is the two-minute rule in GTD?

The two-minute rule says that if a clarified task takes under two minutes, you do it immediately rather than tracking it. Filing and re-reading a tiny task costs more time than just finishing it.

Does GTD help you set goals?

Not really. GTD names goals as a horizon of focus but gives you no way to make one measurable or track progress toward it. Griply adds that layer by giving every Goal a start value, target value, and logged progress.

What is the best app for getting things done?

Any app with a reliable inbox and review flow can run GTD. Griply goes further by linking each task up to a measurable goal, so your next actions connect to outcomes.

Why a capture method needs a goal layer

GTD solved the storage problem: get commitments out of your head, define the next action, review weekly. That part holds up, and the research on offloading and plan-making explains why it feels like such relief. You can run a clean GTD workflow for years and stay productive.

What it cannot tell you is whether the actions you finish add up to the outcomes you wanted. The method's own Horizons of Focus name goals and purpose but give you no way to make a goal measurable. More discipline inside the list will not fix this. You need a measurable goal that your next actions connect to.
