Prioritization matrix: 4 models to decide what to do first
Contents
When everything feels important, your to-do list turns into a list of reproaches. A prioritization matrix does one job: it compares your options against two or three explicit criteria, so you can decide quickly and without guilt. There are several, and they don't answer the same question.
What is a prioritization matrix?
A prioritization matrix ranks your tasks against criteria chosen in advance, often two axes that form four boxes. Instead of asking "what do I feel like doing?", you ask "what ticks the most boxes?".
The value isn't the grid itself but the decision it forces. Putting a task in a box means accepting that another one waits. That is exactly what's missing when your inbox feels like an overload problem rather than a choice.
One rule applies to every matrix: keep it simple. If filling in the grid takes longer than doing the first task, the method has lost.
The 4 most useful matrices
1. The Eisenhower matrix crosses urgent and important. Four boxes: do now, schedule, delegate, drop. It's the best known and the best suited to daily work. Try it with our free Eisenhower matrix tool.
2. The impact/effort matrix crosses what a task brings and what it costs. You get quick wins (high impact, low effort) to do first, big projects to plan, small fill-in tasks, and the ones to forget. Ideal for sorting a list of ideas.
3. The MoSCoW method, from the DSDM agile framework, sorts each item into Must have, Should have, Could have and Won't have (this time). The Agile Business Consortium guide recommends keeping Must haves under 60% of the effort, to leave a margin. It even suggests using it for your own to-do list.
4. The RICE score, popularised by Intercom, multiplies Reach, Impact and your Confidence in those estimates, then divides by Effort. The result is a single score that compares very different projects. Heavier, it mostly serves product teams.
Which one should you choose?
For your day, use Eisenhower: two questions per task, a decision in seconds. For sorting ideas or workstreams, use impact/effort: it surfaces the quick wins people tend to forget.
For a project with a fixed deadline, use MoSCoW: it forces the team to say what can be dropped if time runs short. For a product backlog full of requests, use RICE: the score limits debates of opinion.
Whatever the matrix, add one last filter, the idea behind the Domino method: among what remains at the top, which task would make the others easier or unnecessary? That one goes first.
Applying a matrix to your email
Your inbox is a to-do list that other people write for you. Applying a matrix to it changes everything: every message goes through the same question instead of being handled in order of arrival. To start, drop your last ten unread emails into an Eisenhower grid with our free tool.
A pattern shows up fast: many "urgent" emails matter to no one, and one or two important ones have been sitting there for days. They're often follow-ups you're waiting on, or decisions only you can make. Whether you aim for Inbox Zero or Inbox One, that is where the leverage is.
Virtus Lever does this sorting for you. It connects to Gmail, Outlook or any IMAP address with read-only access, and its Domino algorithm shows you each morning the highest-leverage email, the one that unblocks the rest. Keep your matrix for your tasks; let Lever handle your inbox.
