Why every workplace needs a fishbone diagram

Ever sat in a meeting where everyone threw out reasons to why something went wrong, only to walk out more confused than when you walked in?

Maybe sales dropped last quarter, a big client suddenly left, or your team’s latest project blew right past its deadline. Everyone has a theory:

• “It’s the economy.”
• “It’s because our process is outdated.”
• “It’s because marketing didn’t do enough.”
• “It’s because Jim takes three-hour lunches.”

(Okay, Jim might still be partly to blame.)

The point is, workplace problems are rarely caused by just one thing. They’re usually a tangled web of people, processes, policies, tools, timing—and yes, Jim too.

That’s where the fishbone diagram comes in.

It’s a simple, almost cartoonish tool that helps you break down messy problems into clear, manageable pieces so you can see what’s really going on. Think of it like drawing a map to trace all of the little paths that led you into this mess.

It’s called a fishbone diagram because it literally looks like the skeleton of a fish (which may seem odd). But once you try it, you’ll realize it’s one of the most practical, no-nonsense ways to figure out root causes—whether you’re dealing with slipping sales numbers or why the air conditioner in Conference Room 4 isn't working.

In this article, we’ll dive into what a fishbone diagram is, how it works, and how you can use it at your workplace to solve problems both big and small. We’ll go through real examples, benefits, a step-by-step guide, and even give you some ideas for making your own (without feeling like you’re back in school drawing biology diagrams).

What is a fishbone diagram?

Now that we’ve agreed that workplace problems are rarely the fault of just one thing (or one person taking suspiciously long lunches), it’s time to introduce the real star of the show: the fishbone diagram.

At its core, a fishbone diagram is a straightforward way to figure out why something went wrong—or even why something went unexpectedly right. It’s called a fishbone diagram because, as already mentioned, it looks like a fish's skeleton. You’ve got a central “spine,” lines branching off like ribs, and at one end is the head, which is your main problem or effect.

It’s also known as an Ishikawa diagram, named after Kaoru Ishikawa, the Japanese quality control pioneer who introduced it back in the 1960s. (Imagine caring so much about fixing problems at work that you invent a diagram still being used worldwide decades later.)

How to create a fishbone diagram

Alright, let’s get to the heart of it. The diagram is simple, collaborative, and honestly a nice break from your daily routine (or should I call it office work?). 

Here’s how you actually build a fishbone diagram—without it feeling like a high school lab assignment.

1. Pin down the problem (the fish's head).

Start by writing out exactly what you’re trying to figure out. This goes at the head of your fish, usually on the right side of your page or whiteboard. 

Be specific:

• “Customer complaints have increased by 30% in two months.”
• “Projects are consistently missing deadlines by 2 weeks.”

Not just:

• “We have issues.”

Being clear helps everyone stay focused.

2. Draw the spine.

Next, draw a long horizontal arrow pointing toward your problem statement. This is the spine of your fish. In other words, the backbone that everything else connects to.

3. Identify main categories (the big bones).

Now draw diagonal lines coming off the spine, like ribs. These are your major categories—the broad areas where problems could be lurking.

For most workplaces, categories might include:

• People: Skills, training, attitudes
• Process: How work flows, bottlenecks
• Tools and tech: Software, equipment, systems
• Materials/resources: Inputs needed to do the job
• Environment: Physical workspace, remote setup
• Management/policies: Rules, leadership, priorities

Adjust these based on what makes sense. A marketing team may use “Campaign Strategy” or “Messaging” instead. A software team may add “Code Quality" or "Testing". 

4. Brainstorm possible causes under each category.

This is where the diagram fills out and where the magic happens.
Ask your team: “What’s contributing to this problem under each of these areas?”
Keep it open. No blaming, no shutting down ideas. Just jot everything down.

For example, under Process, you may get:

• “Too many approval steps delay work.”
• “Changing requirements mid-project.”

Under People, maybe:

• “New hires are still learning.”
• “Team morale is low.”

5. Keep digging deeper.

For each cause, ask “Why does this happen?”

Sometimes you’ll add smaller lines off the main “bones,” breaking causes down further. This helps you find the root cause and not just surface-level symptoms.

6. Review and highlight what stands out.

Once your fishbone is filled out, step back and look for patterns. 

• Are lots of causes clustered under “Process” or “Management”?
• Are there multiple issues tied to training or unclear roles?

Circle or highlight the biggest contributors. These are where you’ll want to focus solutions.

7. Turn insights into action.

The fishbone diagram by itself doesn’t solve the problem; it just shines a big bright light on what’s causing it. From here, turn these insights into a plan:

• Fix inefficient processes.
• Offer training where there are skill gaps.
• Adjust timelines if management’s expectations are off.

That’s it. You’ve built a fishbone diagram that turns messy conversations into a clear picture of what’s really driving your problem.  

Example of a fishbone diagram

Let’s make all of this talk of fish skeletons a little more real.

Because it’s one thing to keep saying, “Use a fishbone diagram to find the root cause!” and quite another to see what that actually looks like inside a workplace where people are juggling deadlines, dashboards, and too many meetings.

So here’s a simple, realistic example that almost any team can relate to, showing how a group ended up mapping out a fishbone diagram together.

The scenario: Why are our projects always late?

Picture this.

You’re in a conference room (or maybe a video call), trying to figure out why the last three big projects all missed their deadlines by weeks. The mood is tense. Clients are getting restless. Your team is overworked and under-caffeinated.

Everyone has a theory. 

• The developers insist it’s because the requirements keep changing halfway through.
• Marketing thinks the devs are too slow.
• Management, of course, thinks the team just needs to “hustle harder.”

It’s all swirling opinions, and no clear answer.
So instead of going around in circles, someone says, “Let’s map this out with a fishbone diagram and see where the real problems are.”

1. They build their fishbone diagram together.

They head to the whiteboard.
On the right side, they write their glaring problem in big, slightly frustrated letters: Projects consistently miss deadlines. That’s the “head” of their fish. From there, they draw a long arrow pointing back, giving them a spine to build on.

2. They fill in the major categories.

Next, the team throws out all of the big areas where they suspect issues might hide. They land on:

• People: Skills, experience, communication
• Process: Workflows, approvals, bottlenecks
• Tools: Software, hardware, systems
• Resources: Budget, staffing levels
• External factors: Clients, market changes
• Management: Priorities, leadership style

They sketch these out like ribs branching off the spine.

3. They dig into each area: the messy reality

Now you and the team brainstorm under each “bone.” This is where it gets interesting—and honest. For example:

People:

• Several new hires are still figuring things out, slowing progress.
• When key people take leave, the handovers are shaky.
• The whole team is stretched thin across too many simultaneous projects.

Process:

• Work has to pass through too many approval layers, causing constant waits.
• Requirements keep changing halfway through, sending developers back to square one.
• Clients aren’t given clear timelines, so they make late requests that derail plans.

Tools:

• Their project management software often has outdated data, so no one’s truly sure what’s on track.
• Reporting is mostly manual, taking hours that could be spent on actual project work.

Resources:

• Budget cuts earlier in the year mean fewer people than planned.
• There’s a hiring freeze, so no reinforcements are coming any time soon.

External factors:

• Clients take forever to give feedback or sign off on work, stalling the next phases.
• Vendors delivering key components have missed their promised dates more than once.

Management:

• Priorities keep shifting, forcing the team to drop one project for another.
• Unrealistic initial timelines are set without input from the people doing the work.

By the time they’re done, the whiteboard looks like the skeleton of a very stressed fish—covered in scribbles, arrows, and underlined frustrations. But it also tells a story that’s much clearer than before.

This isn’t just about slow developers. Or about client's changing requirements. Or about management pushing too hard. It’s about all of these things layering together:

• Inexperienced staff are still onboarding.
• Clunky tools waste time.
• Unclear processes let work bounce around aimlessly.
• Management sets overly ambitious deadlines without input from the ground.

The clarity that follows

When they step back, it’s obvious why the projects keep missing deadlines.
More importantly, it shows them exactly where to start fixing things like streamlining approvals, looping developers in when setting timelines, and pressing vendors for more reliable delivery schedules.

Instead of leaving the meeting with more heated opinions, they walk out with a shared understanding of what’s going wrong and a starting point for making real improvements.

The benefits of using a fishbone diagram

After seeing how that team finally made sense of their missed deadlines, it’s pretty clear: The humble fishbone diagram does more than just fill up whiteboard space.

It’s one of those tools that looks deceptively simple, but does much more when it comes to solving real problems. Here’s why.

1. It stops the blame game.

Let’s be honest. Without a structured way to look at problems, most team discussions turn into a low-key blame session.

• Marketing blames Sales.
• Sales blames the Product team.
• The Product team blames “market forces.”
• Everyone blames whoever set the original timeline.

A fishbone diagram forces everyone to step back and see the bigger picture. It lays out all possible contributing factors side by side, so the conversation becomes less about “Who’s at fault?” and more about “What’s really causing this?”.

2. It uncovers hidden causes.

Sometimes, the real reason for why things go wrong isn’t obvious.
Maybe your delays are partly due to new team members who are still learning. Maybe outdated software is quietly adding hours of manual work each week. Or maybe a complicated approval process is eating up days you didn’t even realize were missing.
Drawing it all out on a fishbone lays them clearly on the table.

3. It organizes messy thoughts into a clear picture.

Most workplace problems are a tangled knot of people, tools, timing—and sometimes, a bit of bad luck, too. A fishbone diagram takes that mental spaghetti and untangles it into a neat, visual map.
Instead of trying to keep track of everyone’s theories in your head (or a 42-page email thread), you can look at the diagram and immediately see how everything connects.

4. It brings the whole team into the solution.

When you build a fishbone diagram together, it stops being your problem or their problem. It becomes everyone’s shared project to figure out.
This is huge. It means more buy-in when it’s time to actually fix things because everyone helped diagnose what’s wrong in the first place.

5. It’s quick, cheap, and doesn’t require any fancy software.

No expensive consultants. No days lost building complex dashboards. Just a normal board (or an online board if your team’s remote) and some honest conversation.
In less than an hour, you can often spot the main roots of your issue—something that may otherwise take weeks of back-and-forth emails.

6. It works for literally any problem.

• Projects running late? Fishbone diagram.
• Customer complaints on the rise? Fishbone diagram.
• Employee turnover creeping up? Fishbone diagram.

The point is, this tool is incredibly flexible. If there’s a problem with more than one possible cause, the fishbone diagram is worth a try.

In short…

It’s not magic. It won’t fix your problems on its own.
But it will shine a giant spotlight on what’s actually driving them so you can stop guessing, stop blaming, and start solving.

Wrapping up: Your new favorite skeleton

What may have looked like a strange fish skeleton at first is actually one of the most useful tools for untangling problems at work.

Fishbone diagrams help teams move past scattered opinions and gut instincts. They make it easier to map out all of the moving parts, connect the dots, and figure out where things are really going off track. In a workplace full of cluttered spreadsheets and never-ending email threads, that kind of clarity is rare—and seriously underrated.

So the next time your team is scratching their heads over a stubborn problem, you’ll know exactly what to say: “Grab a marker. Let’s draw a fish!”
