Four-Criteria Model

The Four-Criteria Model is a sequence for choosing what to do next: context, time available, energy available, and priority, in that order. Its significance lies not just in ranking tasks but in making action fit the actual conditions of the moment. A well-organized reminder system narrows the field before a person must choose, so a brief opening in the day, a particular tool, or a low-energy spell can become an opportunity to complete something appropriate rather than another occasion for searching and reconsidering.

Definition and Order

The model begins with the most immediate constraint: context. It then considers how much time is available, how much energy the person has, and finally the relative priority of the remaining options. The sequence matters. Priority is not assessed in the abstract or across every imaginable task; it is weighed among actions that can be performed in the current place, with the tools and time at hand, and at the person’s present level of energy.

The book presents this bottom-up approach as a way of making action choices usable in ordinary conditions. Someone may have many commitments, but only a subset can be acted on now. The model does not promise that every task will fit every moment. Instead, it identifies which constraints are decisive first, leaving a manageable choice among the actions that remain possible.

Context as the First Filter

Context asks what can be done where the person is, with the tools available and the people accessible. A phone, a computer, a store, or the presence of someone who needs to be consulted can determine which actions are possible. If an action requires a different location or tool, it need not occupy attention as a live option in that moment.

This first filter explains why the book recommends organizing reminders by context. Lists such as Calls, At Home, At Computer, Errands, or an agenda for a particular person make the available choices easier to see. If someone is stuck in traffic and can act only by making calls, a Calls list presents relevant work without requiring a fresh scan of unrelated tasks. The lists can effectively fold in or out according to what is possible at a given time.

Context-based organization also forces a useful decision earlier in the process: what is the next physical action? To place an item on a computer, phone, or errands list, the person must determine what doing it actually requires. A miscellaneous list can weaken that discipline because it permits an item to remain vague about both its setting and its next step. Processing incoming work into context categories, by contrast, grounds projects in actions that can move them forward.

Time and Energy

After context comes time. An action suited to a clear two-hour stretch may not be the right choice when a meeting begins in ten minutes. A complete inventory of reminders makes it easier to match work to available windows: a short interval can be used for a short action rather than lost because the list contains only large or important tasks. The book calls attention to the small, irregular gaps in the day, which can be useful when the actions have already been clarified and sized appropriately.

Energy is the third criterion because time alone does not determine what a person can do effectively. After a long budget-planning session, for example, the remaining energy may be poorly suited to calling a prospective client or drafting a performance-review policy. Changing an airline reservation, processing expense receipts, or skimming a trade journal may be more realistic alternatives. The point is not that low energy makes action impossible, but that the available actions should be matched to the kind of effort the moment can support.

A cleanly organized system helps preserve activity when a person is not at full strength. Disorganized reading material, scattered receipts, chaotic files, or a dysfunctional in-basket can make even finding the next task feel like too much work, encouraging avoidance. Having some straightforward actions ready to complete gives a person a way to keep moving without first rebuilding the system or solving a demanding problem. In this sense, the first three criteria depend on having next-action reminders prepared in advance: the choice can then be made from defined options even when the person is not in a mode to think through every project from scratch.

Priority, Preparation, and Completion

Priority is considered only after context, time, and energy have narrowed the field. The question is which remaining action matters most. This order offers a practical answer to the difficulty of having more to do than can comfortably be handled: it does not erase the need for hard choices, but prevents priority from being confused with immediate feasibility. A highly important action may not be possible in the current context or energy window; another suitable task may be the better choice now.

The tire-store example shows how preparation turns the model into action. Someone who needs new tires may have carried that concern for a long time and may repeatedly have had access to a phone, yet still not have called. The obstacle is not necessarily a lack of time; it may be that each moment requires reconsidering the whole set of projects and identifying what to do. Once the next action has been decided in advance, a fifteen-minute interval before a meeting, a phone at hand, and modest energy can make calling for prices a clear, manageable option. A large client proposal would not fit that same window, but the call can be completed successfully.

The resulting sense of progress matters. Completing a small action can provide a concrete win suited to the time and energy available, while the larger project remains intact as a series of next steps rather than an indistinct burden. The model thus links organization to motivation: prepared choices reduce the need to begin with difficult planning each time, and completed actions make progress visible.

From Personal Choice to Shared Responsibility

The same next-action emphasis applies to collaborative work. Meetings can end with a vague sense that something ought to happen, while each participant hopes the responsibility belongs to someone else. Asking what the next action is, and who will take it, makes the work and its owner clearer. The book treats that clarity as a form of practical respect: people should not leave a discussion uncertain about what has been decided or who is responsible.

Long-term projects are not exempt from this discipline. A distant deadline does not mean a project is merely for someday; it can still require action now, even if many steps remain before completion. Monitoring projects and open loops, and clarifying actions at the front end rather than waiting for pressure at the back end, supports operational responsiveness. The four criteria govern the choice among actions, while explicit next-action decisions ensure there is something concrete to choose from.

The model’s broader consequence is a shift from reacting under external pressure toward initiating change. The book associates that shift with a stronger sense of self-worth and control: defining the next move assumes that a situation may be changed and identifies a possible contribution to that change. Even a complaint can be brought back to the same practical question. If the condition can be changed, an action can help change it; if it cannot, it must be treated as part of the circumstances within which plans are made. The four criteria therefore connect moment-by-moment task selection with a larger practice of taking responsibility for what can be done.
