What our users say

Marcus Thorne, Senior Mechanical Engineer

We had a recurring failure in one of our hydraulic pumps and couldn't pinpoint the source. I used this diagramming tool to map out every potential factor, from material fatigue to environmental humidity. The one-click beautify feature was a lifesaver because I had to present my findings to the board just two hours later. It made my messy brainstorm look like a professional report. We eventually found it was a cooling issue, and the visual layout helped the non-engineers understand exactly why we needed the budget for a fix.

Sarah Jenkins, High School Science Teacher

Teaching root cause analysis to teenagers can be difficult, but the templates here changed everything. I found a great fishbone sample that looked like an actual fish, which kept the kids engaged. We worked together on the whiteboard using the online version to figure out why a local pond's pH levels were dropping. Being able to export the final result as a PDF meant I could upload it straight to our classroom portal for them to study later. It is much more effective than just drawing on a chalkboard.

Elena Rodriguez, Operations Consultant

I spend a lot of time on the road, so having a tool that works on my tablet and my laptop is crucial. I was at a client's warehouse last week and used the touch interface to sketch out a supply chain delay analysis right there on the floor. Later that night at the hotel, I logged in on my laptop to polish the diagram and add more detailed symbols. The presentation mode is great for client meetings because I don't even have to leave the browser to show a professional slideshow.

FAQs About EdrawMax Fishbone Diagram Tools

What is a fishbone diagram?

A fishbone diagram, also known as an Ishikawa or cause-and-effect diagram, is a visualization tool used to identify potential causes of a specific problem. Its structure resembles a fish skeleton, with the main problem at the head and various contributing factors branching out like bones to categorize root causes effectively.
What are the "6Ms" commonly used in these diagrams?

The 6Ms are standard categories used to organize potential causes in manufacturing. They include Manpower (people), Methods (processes), Machines (equipment), Materials (raw goods), Measurement (data/standards), and Mother Nature (environment). Using these categories helps teams ensure they explore all possible avenues when investigating why a specific technical or production failure occurred.
How do I begin the process of creating a fishbone diagram?

Start by clearly defining the problem statement and writing it at the "head" of the fish on the right side. Draw a horizontal line extending left, then add diagonal "ribs" representing major categories of causes. Finally, brainstorm specific factors for each category and list them as smaller sub-branches.
How does a fishbone diagram differ from a standard mind map?

While both are visual tools, a mind map is generally used for broad idea generation and exploring general concepts. In contrast, a fishbone diagram is specifically focused on identifying the root causes of a single, defined problem. It follows a more rigid, hierarchical structure designed to facilitate systematic cause-and-effect analysis.
