What is Getting Things Done (GTD)?

Allen’s starting observation is that the mind is good at having ideas and bad at holding them. Every commitment you keep in your head, from “call the dentist” to “rethink the pricing page,” takes up attention whether or not you can act on it. That is why an unfinished errand surfaces at 2 a.m. and why a long day can feel exhausting even when little got done.

GTD matters because it offers a complete answer rather than a tip. Capture gets commitments out of your head. Clarify turns vague items into concrete next actions, or into projects when more than one step is needed. Organize puts each action where you will see it at the right moment: a next-actions list by context, a calendar for hard appointments, a waiting-for list for delegated work and a someday/maybe list for ideas you are not ready to pursue. Reflect keeps the system current through a weekly review, and engage is the part where you actually do things, choosing by context, time available, energy and priority.

Twenty-five years on, most task apps borrow from GTD, and methods like Inbox Zero are direct descendants of its “process, don’t browse” rule.

GTD can feel heavy at first. A lighter path in:

• Do one big capture. Write down everything that has your attention, work and personal, into a single inbox. Expect a hundred items or more the first time.
• Clarify each item with one question: what is the next physical action? “Plan offsite” is a project; “email venue for availability” is an action.
• Apply the two-minute rule. If the action takes under two minutes, do it during clarifying.
• Organize by context. Group actions by where or how you can do them, such as at computer, on phone, errands or with a specific person, so the list you see matches the situation you are in.
• Keep a waiting-for list. Every delegated task and every question you have asked goes here with a date.
• Put only hard commitments on the calendar. Appointments and deadlines, not tasks you hope to get to.
• Run a weekly review. Once a week, empty inboxes, review every list, update projects and look at the calendar two weeks ahead. This is the step that keeps the system trustworthy.

Allen also recommends the Eisenhower Matrix style question of importance when choosing what to engage with, and the free weekly planner can draft the coming week from your next-actions list.

Fluidwave was not built as a GTD app, but its task model maps closely onto Allen’s lists. Capture is the “What would you like to do?” bar, which parses a sentence into a task with date, duration, recurrence, priority and reminder, plus a chat assistant and voice input for hands-free entry. Emails become tasks with one key from the Triage view.

Organize uses Fluidwave’s statuses and organizers. The Draft status holds someday/maybe items. Contexts are a first-class organizer, so you can group and filter actions by where or how you will do them. Projects hold multi-step outcomes, Schedules assign tasks to specific times for focused execution, and Lists and Categories cover the rest. The Waiting status is typed, waiting on a call, an email, a message or something else, and the Active filter hides waiting tasks until they are yours again. Delegate hands a task to a human assistant through the marketplace.

Reflect happens in the views: the assistant can jump you to overdue, upcoming, waiting, delegating and draft tasks, and the Gantt and calendar views show the weeks ahead. Engage is where auto-prioritization takes over, ordering the list by criteria you rank so the top item is the next action. A recurring task can hold the weekly review itself.
