The right first step is the one that makes the most other things possible
When several things are ready to start simultaneously, the instinct is often to begin with the most visible, the most urgent, or the one that feels most manageable. None of those is a reliable guide to the right first step.
The right first step is usually the one whose completion enables the most subsequent progress — the task that is a prerequisite for others, that removes the most uncertainty about what follows, or that other people are waiting on before they can begin. Starting there creates momentum that compounds through the rest of the sequence. Starting elsewhere creates the appearance of progress without advancing the part that matters most.
Pairwise comparison identifies the right first step by testing the candidates directly against each other — which of these two should come first, and why — rather than trying to rank a full list simultaneously, where the interactions between tasks make accurate assessment considerably harder.
What is making the first step unclear
The first step is usually unclear for one of a small number of reasons — identifying which one applies changes what the right response looks like
Different causes of uncertainty respond to different interventions.
Competing urgency is one of the most common causes. When multiple things have real deadlines or real stakeholders pushing for progress, the legitimate claims of different starting points can be genuinely difficult to separate. The question in that situation is not which is most urgent but which creates the most downstream value when completed first.
Avoidance is another. The task being avoided — the difficult conversation, the hard decision, the piece of work that requires the most concentration — is frequently the one that would unlock the most if it were done. Its apparent unreadiness for first position is often a symptom of the avoidance rather than a genuine sequencing reason.
Unclear goals are a third cause. When the overall objective is not precisely defined, the sequence cannot be optimised because it is not clear what the sequence is trying to achieve. In that situation, defining the goal is the actual first step — everything else follows from it.
Comparing the candidates for first position directly
The candidate that wins the most direct comparisons is the right first step
This is what pairwise comparison is specifically designed to establish.
The practical question for any candidate first step is: if this were done before the others, would the subsequent steps be easier, faster, or more certain? A task that scores consistently on that question across multiple comparisons is the right starting point — not because it is the most urgent or the most visible, but because its completion creates the most downstream value.
The comparison also surfaces avoidance. A task that keeps losing in direct comparison to less important items — that is consistently displaced by things that feel more manageable — is worth examining. The pattern of avoidance is itself a signal about where the real work is.
When multiple tasks have a legitimate claim to go first
When more than one task has a genuine case for first position, one criterion needs to dominate
It is possible for multiple tasks to have legitimate claims to first position at the same time — a prerequisite for downstream work, a task other people are waiting on, a decision that removes significant uncertainty, and a time-sensitive item can all exist simultaneously. When they do, trying to satisfy all of them produces paralysis rather than a starting point.
The criterion that should dominate is the one whose cost is highest if ignored. In most cases that is the task that blocks others — because leaving a blocker in first position costs time and effort across multiple subsequent steps, not just this one. But when all tasks are genuinely independent, the criterion shifts to whichever removes the most uncertainty about what follows.
Establishing that explicitly makes the starting point resolvable rather than a matter of continued deliberation.
The three principles that determine the right first step
One of these three principles will resolve the starting point for most sequences
Starting with the task that is a prerequisite for everything else means the sequence has a clear dependency structure and one task must precede all others. This is the most common resolution for sequencing questions — and the most reliable, because it is determined by the structure of the work rather than by judgment or preference.
Starting with the task that removes the most uncertainty means the sequence does not have a clear dependency structure, but one task would make the rest of the sequence considerably clearer or easier to plan. This is the right call when the work involves significant unknowns that are best resolved early rather than carried through the sequence as sources of ongoing ambiguity.
Starting with the task that other people need before they can begin means the sequence involves parallel workstreams or other people whose progress depends on an output from this one. Producing that output first removes the constraint for everyone waiting — which multiplies the value of the first step beyond its direct contribution to this sequence alone.
