What do you like best about Epsilon3?

I like that Epsilon3 makes it easy to organize and update SOPs in a clear, structured way, which helps keep the team aligned. The interface is simple enough that new team members can get up to speed without much training. Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

I dislike that it has limited integration options with other tools we use, which sometimes adds extra steps to our workflow. It would be more efficient if it could sync more easily with our existing project management and communication tools. Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

Epsilon3 is solving the problem of scattered or outdated SOPs by providing a centralized place to create, update, and track procedures. This helps you maintain consistency across your team, reduce errors, and save time by making sure everyone is following the most up-to-date process. Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks for the feedback! We're always working to add more integrations, and we already support Jira, Slack, and more. Are there specific tools you want added?

What do you like best about Epsilon3?

I use Epsilon3 almost daily when deployed to our test site, and semi regularly when working from the office.

Compared to other test procedure writing/execution software I have used, Epsilon3 has the most functionality, smoothest operation (in terms of loading in a web browser and allowing steps to be executed quickly and easily), and most logical user interface (no hidden buttons, well labelled etc.).

We have also moved to version control of high level test and operational procedures, and the ability to suggest edits, add redline/blueline steps to procedures as they are conducted is a very effective way to save suggested changes without unapproved changes to the released procedures.

We also work at a remote test site which has limited network coverage. Epsilon3 has worked flawlessly, allowing us to continue testing and completing procedures even with intermittent network access.

The ability to have simple logic/numerical calculations built into run steps is also a great feature, eliminating the need for operators to do manual calculations in high stress environments.

Coming from our other software packages, procedures can be far more easily written and implemented, even for inexperienced users.

I can't comment on customer/technical support as I still haven't had to use it! Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

I don't have any notable dislikes of Epsilon3! Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

Epsilon3 has been invaluable for execution of testing activities which need to follow a defined procedure. When conducting tests, we need to be able to focus on the task at hand. Having an efficient, non laggy software package is critical for this to avoid unnecessary distractions and time lost while testing. Epsilon3 has provided this. Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks for the review! You can already add photos to any run step in the comment field or by dragging and dropping a photo or clicking add attachment and taking a photo from the camera directly. You can also use the attachment field input type to require a photo on a given step.

What do you like best about Epsilon3?

I really like how intuitive the tool is. I had to create new procedures during a launch campaign with only little time to spare. Althougth I only had little prior experience with epsilon I was able to create the checklists I needed without spending much time on learning to use the tool. I also like that the tool is web based. As long as you know your login data you can use it on any device anywhere. Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

The print function could use some refinement. At least in Firefox when you print a checklist epsilon only uses the standard print function of the webbrowser, which outputs non-ideal documents. Sometimes a workstep gets cut in halve at the end of the page and the rest is printed on the next page. This can be a bit confusing when you are working under pressure at the launch pad. Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

Helps me to quickly create checklists/procedures which keep me from making mistakes while working on fligth hardware. Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks! Sorry about the issues with print; we'll work to improve that!

What do you like best about Epsilon3?

Its intuitive interface makes it easy to follow procedures and coordinate across teams, reducing errors and time delays—critical benefits in industries where precision and efficiency are paramount. The platform’s integration capabilities with other data sources and tools help create a seamless, centralized place for monitoring processes and sharing updates. Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

One potential drawback of Epsilon3 could be its learning curve for teams who are new to digital procedure management or transitioning from traditional methods. Adapting complex workflows to the platform’s structure may initially require time and training, especially for teams unfamiliar with similar systems. Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

Improved Accuracy and Consistency: By digitizing procedures, Epsilon3 reduces errors that might occur with manual processes, ensuring that everyone follows the latest version of any given procedure.

Increased Efficiency: With faster access to procedures, an intuitive interface, and built-in tracking, teams can save time and focus on executing their tasks rather than managing paperwork. Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks for the feedback! We are working on some ways to make the new user experience and initial training easier.

What do you like best about Epsilon3?

Epsilon3 makes it very easy to create procedures by giving many options to build upon. The ability to assign reviewers, and give users different roles that they are allowed to sign off on are most helpful to me. There are many different ways to create steps for procedures with pretty much any form of user input - photos, checkboxes, user type input as well as more automated integration types. It has made what used to be printed out procedures to a much smoother, faster way of working Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

Repeating procedures can be sometimes hard to manage if something is being repeated many times. It would be nice if the old sections that are now being repeated could be hidden and not take up limited space on the side bar. You could have option to show them and of course see them when procedure is over but ultimately they are out of the way to not confuse where you are at the time of running them. Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

Constantly having to print out procedures is a hassle, editing them had no formal way of reviewing and ultimately was changing an excel sheet. Epsilon 3 allowed reviewers to be assigned and formarlized the release of procedures that had been reviewed for safety, and correctness Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks, Zachary! This is super helpful feedback. We're working on some improvements for how we handle repeats and the UI around that, so we will take your ideas into account.

What do you like best about Epsilon3?

We, in our company, use Epsilon 3 daily. I think Epsilon3 is a good knowledge base tool for procedures. It’s really helpful because it breaks down each article into clear, simple steps. This can be especially useful for new team members as it makes it easier to learn and follow the process. Review collected by and hosted on G2.com.

What do you dislike about Epsilon3?

I’m not a fan of the interface (it looks a little old) and the procedure titles with the codes can be a bit confusing which makes it harder to search for the right knowledge base and is a little time consuming.

While it can be helpful for new hires, it can be frustrating for senior team members. The procedure sections are not searchable until they are opened, so using ctrl+f doesn’t always work correctly unless each section containing the specific keyword is opened first. Review collected by and hosted on G2.com.

What problems is Epsilon3 solving and how is that benefiting you?

We use Epsilon3 as a knowledge base for our internal company's articles and guides. Some of these cover technical topics, which help me and others in the company find the right troubleshooting steps when needed, others focus on procedures - like resetting customer passwords or updating their account information on file. As I mentioned earlier - it's a great tool for the new hires as the procedures can be organized in step by step guides, making them easy to follow. Review collected by and hosted on G2.com.

Response from Max Mednik of Epsilon3

Thanks! We'll work to make procedure search inside procedures better!
