Impact/Effort Matrix
Score each task on two things: what it’s worth, and what it’ll take. The four quadrants turn a long list into an order you can act on. What to do now, what to plan for, and what to let go.
The size of the list doesn’t matter. It works just as well on a weekend of chores, on the fixes your shop has been putting off, on a quarter of work with your team, or on a project with a hundred moving parts.
Free forever, and no account. Your team scores privately on their own phones, so the first opinion doesn’t set the tone for everyone else. Add tags and owners, filter the board, keep as many boards as you need, and export a PNG or CSV when you’re done.
Also called an action priority matrix, an impact ease matrix, or a PICK chart. Same grid, different names. You can switch the tool between the classic wording and PICK at any time.
tl;dr
Two questions will sort almost any list
Long lists are hard to prioritize because every item looks reasonable on its own. Held up one at a time, nothing is ever obviously the thing to cut, so the list just keeps growing.
A matrix makes you compare them instead. You ask two questions about every item, and only two: what do I get out of it, and what will it cost me. Plot those against each other and the list falls into four groups, and the conversation changes from “is this a good idea” to “is this better than that.” The second one is much easier to answer together.
People reach for it in three ways, mostly. Sorting a to-do list that got away from them. Going through a pile of ideas after a brainstorm, to see which ones are worth anything. Or laying out a quarter, a season, or a year of work with a team and deciding what actually gets attention.
The rest of this page covers what each group means, how to run the exercise so it holds up, and the ways it goes wrong.
Reach for it when any of these sound familiar.
- The list is too long to hold in your head.
- Everything on it is a priority, which means nothing is.
- Two people want different things and neither can say why.
- You need to drop something and want a reason you can defend.
- A new quarter, sprint, or season is starting.
Skip it when the work is already decided and you just need an order to do it in. That’s a calendar problem, not a prioritizing one.
Reading the board
What each group means, and what to do about it.
Quick Wins · High impact, low effort
Start here. These build momentum and give you something to show early. Teams tend to underrate them, assuming anything easy can’t matter much. Don’t be surprised if you only get a couple. Most lists don’t have many.
Major Projects · High impact, high effort
Worth doing, but they need real planning and real staffing. Load up on these with no quick wins in the mix and you’ll lose momentum before anything ships. Break the big ones into pieces and hand pieces out, or they’ll sit untouched for a year.
Fill-Ins · Low impact, low effort
Fine when there’s room, but they feel more productive than they are. Easy to start, easy to finish, and a comfortable place to hide from harder work. Fit them into the gaps, after the top two, not instead of them.
Thankless Tasks · Low impact, high effort
Cut them, automate them, or hand them to someone they’d be easier for. When one is unavoidable, do it as cheaply as you can and don’t let it become somebody’s week.
Running Lean Six Sigma? The same four boxes are called Implement, Challenge, Possible, and Kill on a PICK chart. There’s a switch in the tool to use that wording instead.
Running a session
Five steps, and what usually goes wrong at each one.
- 1
Agree on what the axes mean
Write down what impact and effort mean for this session before anyone scores anything. Impact might be revenue, retention, risk, or hours saved. Decide whether effort counts coordination, not just build time.
What goes wrong: Without shared definitions, everyone reads their own meaning into every score, and you spend the session arguing past each other.
- 2
Get every item on the list
Add them one at a time, or paste the whole list in. Be specific enough that two people would picture the same work.
What goes wrong: Nobody can score “improve performance.” Vague items get vague scores, and you end up with a board nobody trusts.
- 3
Score privately, before anyone sees the board
Everyone rates each item on its own. In a team session that happens on separate phones, and nobody sees a score until everyone has finished, including you.
What goes wrong: Once one item is on the board, everyone rates against it, and whoever went first has set the scale for the whole session.
- 4
Reveal, then go straight to the disagreements
Start with the items your team scored most differently. A wide gap usually means somebody knows something the others don’t.
What goes wrong: Average the scores and move on, and you throw away the most useful thing the session produced.
- 5
Turn quadrants into a plan, and run it again later
Schedule the Quick Wins now, staff the Major Projects properly, batch the Fill-Ins, and cut the Thankless Tasks. Export it so you still have it next week.
What goes wrong: Priorities move, so run it again each planning cycle. A board from two quarters ago tells you what you thought back then, not what to do now.
One more worth calling out: urgent isn’t the same as important. A loud request from a small customer can be urgent and still barely move the needle. If urgency is really the question you’re trying to answer, you want an Eisenhower matrix instead.
Everything’s on the board. Now what?
The board sorts the list. It doesn’t decide for you.
Start with Quick Wins, then Major Projects. That’s the whole recommendation, and it’s worth being blunt about it: those are the two high-impact quadrants, and anything you do from the bottom half is time you didn’t spend on the top half.
Take a couple of quick wins first, even if the major projects matter more. Finishing something early is what keeps people believing the plan is real. Then pick one major project, and only one. Two half-staffed big projects finish later than one properly staffed project, and they cost you the same quarter either way.
Write down what you decided and what you dropped, while the reasons are fresh. In six weeks somebody will ask why their idea didn’t make the cut, and “we scored it low on impact and here’s who was in the room” is a much better answer than trying to remember. Print the board or export it and keep it somewhere the team can find it.
Then run it again next quarter. The scores will have changed, and the ones that moved most are usually the interesting conversation.
When the board looks lopsided
A pile-up in one corner usually says more about the list than the work.
- Nothing in Major ProjectsThe list might be playing it safe. Nothing on it is big enough to change much.
- Almost everything in Quick WinsThe items are probably too small. Try grouping them into the outcomes they add up to.
- A long tail of Fill-InsOften a backlog nobody has pruned in a while. Ask what would actually go wrong if you deleted them.
- Almost everything in Thankless TasksImpact and effort likely got defined too narrowly. Go back and agree on what they mean.
- Everything clustered in the middleScores were hedged, which isn't about one quadrant. Force the calls apart: if two items tie, ask which one you'd cut.
Questions
What is an impact/effort matrix?
It’s a two by two grid for prioritizing work. Every task, idea, or project gets placed by how much value it delivers (impact) and how much time, money, and coordination it takes (effort). That gives you four groups: Quick Wins, Major Projects, Fill-Ins, and Thankless Tasks. Putting the trade-offs somewhere everyone can see them is what makes the conversation productive.
How is this different from a PICK chart or an action priority matrix?
An action priority matrix is the same tool under a different name. Same two axes, and even the same four quadrant names, so if you've seen it called that in a management course, you're in the right place. An impact ease matrix is the same thing again, just swapping effort for ease. A PICK chart is closer to a variant: it came out of Lean Six Sigma at Lockheed Martin and plots payoff against ease, so the grid matches, but the quadrants are named for the decision instead of the category. Possible, Implement, Challenge, Kill. Some people prefer that because "Kill" is a clearer instruction than "Thankless Task." You can switch between both sets of names in the tool, and it only changes the labels, never your scores.
How is this different from the Eisenhower Matrix?
That one's a different tool, not another name for this one. An Eisenhower matrix plots urgency against importance, so its quadrants are instructions about your time: do it, schedule it, delegate it, drop it. It's built for a calendar and an inbox, where the work is already yours and the question is what to touch first. Impact and effort is built for a list of options you're choosing between, where the question is what earns your attention at all. Plenty of people use both, one for the week and one for the quarter. If you catch yourself scoring something high because somebody is shouting about it, that is urgency, not impact, and Eisenhower is the better tool that day.
Is it really free?
Yes, permanently. No account, no trial, no card, no locked features, and no email needed to get your work out. I built it because I run this exercise with clients and the free tools I found were thin.
Why does this ask me to score items before showing the grid?
Because seeing the board changes how you judge things. Once a few items are placed, everything after gets rated against them, and whoever went first has set the frame. Scoring each item on its own first is the usual fix. You can still drag anything around afterward.
How does scoring with my team work?
Start a team session and share the link. Everyone scores on their own phone, one item at a time. Nobody sees any scores while that’s happening, including you, because the server won’t hand them over until you reveal. Then you get one combined board, plus a ranked list of the items your team saw most differently.
Where is my data stored?
Your boards live in your own browser, not on a server. Share links carry the whole board inside the link itself. The one exception is a team session, which has to store the list and the scores so several phones can reach it. You can delete that with one button whenever you want.
What should impact and effort actually mean?
Whatever your team agrees on before you start, which is why the tool asks you to write both down. Impact might mean revenue, repeat customers, risk, or hours saved. Effort usually means time and money, but decide up front whether it also counts the back and forth.
Can I use the keyboard instead of dragging?
Yes. Select any item on the grid and use the arrow keys to move it, holding Shift for bigger steps. Enter opens it for editing, Delete removes it. You can run the whole tool without a mouse, which most matrix tools can’t do.
Prioritizing is the easy half. Doing the work is the other one.
If your list keeps getting longer and nothing moves, scoring probably isn’t the problem. I help founders and small businesses sort that out, then actually build it. The first 10 hours are free.
