Marvelous compared to piles and piles of on-paper checklists

We are still very happy with Epsilon3 two years later -- as the nature of our organization being an educational-oriented aerospace engineering team, its integrated approach to checklists, process management and multi-user collaboration features allows new members and students not familiar to this project before to be able to quickly get themselves up to speed and learn the real world of standardization of complex processes. We expect epsilon3 to continue being a critical centerpiece of our processes for the future to come.

Epsilon3 as a knowledge base

Refined Epsilon3 procedure runs with added time for familiarity do relay the steps that need to be taken clearly.

Epsilon3 Review

After using Epsilon3 for a good length of period, this tool has not improved for user experience. Interface of website is designed in the bad way. It is hard to navigate thru different topics that being added, especially hard to navigate to sub-categories or even narrowed sections as it redirects to the main topic page without any expanded answers. As well there are too many sub-sections on specific topic to research as it gets complicated each time to dive deeper to information.
