  • Let's be honest: acronyms seriously suck. Acronyms slow teams down, make collaboration harder, and in high-stakes operations, they quietly introduce risk. In sectors where definitional precision means the difference between mission success and failure, creating a common operating language is crucial. We've built our Acronym Dictionary to solve that challenge. Learn more about our latest feature from our CEO & Co-Founder Laura Crabtree 👇

    If you've been here a while, you know that we don't like acronyms and are obsessed with the A.S.S rule: Acronyms seriously suck. And now, we've finally built our response to it. Introducing the Acronym Dictionary in Epsilon3. This one's personal. I once sent an email at SpaceX with three acronyms that triggered a company-wide response about how they create noise, slow teams down, and make collaboration harder. That moment stuck with me and I kept seeing and hearing from our customers how this problem is everywhere. Teams use hundreds of acronyms. Some are industry standard. Some were made up by one engineer five years ago and somehow stuck around. New people join and hit walls of text they can't decode. They either stop to ask and feel uneducated, or they don't ask and something slips through. Epsilon3’s Acronym Dictionary fixes that. Here's how it works for you and your team: you upload your acronym library once during setup. From that point on, anyone reading a procedure can hover over any acronym and see the definition instantly. You get clarity right when you need it without hunting through old documents or interrupting someone's day. The industry has lost missions over unclear communication. Acronyms create that same kind of silent risk, the kind that compounds when people assume everyone knows what things mean. This feature is available to everyone now. If you're using acronyms in your operations (and I'm sure you already are) this is for you. I'd love to hear how it works for your team, and if you have feedback, we're all ears!

    Last week, NASA announced a delay to the Artemis II mission after a technical issue during the wet dress rehearsal, one of the final integrated tests before the launch, in which the teams fuel the rocket in the same way that they would during launch. During the test, an inadvertent hydrogen fuel leak occurred, and in troubleshooting the problem, another leak was caused. This is on top of other known challenges involving the Orion capsule's communications connectivity. As a former Missions Operations engineer, I empathize with the Artemis II launch team. I remember the stress of ensuring everything went exactly right for a successful launch. The entire Artemis program is still in its operational infancy, with few true missions to learn and iterate from. We weren’t in the firing room. We don’t know what procedures and sequence of events lead to this unfortunate situation. What we do know is that at the core of this rehearsal sat a procedural playbook—built from years of component tests, simulation, careful choreography and experience. But for me, “inadvertent” is the key word: these dress rehearsals are demanding enough without preventable obstacles compounding the pressure. For these high-stakes missions, even the smartest experts still rely on strong operational processes to minimize risk and ensure mission success. Without a rigorous process built across missions on an iterative basis, underpinned by secure, purpose-built software, to support the entire lifecycle of the mission, projects are much more likely to run into unnecessary trouble. We built Epsilon3 because the stakes are critical in human spaceflight. We connect crews, processes, and systems to give teams clear, real-time visibility across the platform. Our mission is to enable teams with the information necessary and access to catch problems before they even become problems—ensuring missions are equipped to run on-time, smoothly, and safely. NASA pioneered human space flight. They opened the doors to generations that believe humanity’s next great journey is among the stars. As NASA has leaned on commercial space innovation leaders for the past decade to accelerate innovation, now more than ever, that collaboration needs to continue to deepen for us to reach higher and solve the even more complex challenges we face as we look towards the future of deep space exploration. We’re here to help, and ready to answer the call. https://lnkd.in/g28zwids

    The engineer who knew how to troubleshoot that critical system just left. And they never documented the process, critical edge cases, or the reasoning. Institutional knowledge is built through years of hands-on experience, trial and error, and lessons learned the hard way. But if it only lives in people's heads, it walks out the door with them. That's not just inconvenient, it's operational risk. The problem isn't that people don't want to share what they know. It's that most systems make documentation feel like extra work. So knowledge stays scattered across emails, outdated manuals, and whoever happens to remember. Here's what changes when you make documentation easy: it actually gets used. Take onboarding. You hire someone with solid experience, but they're new to your system. In most places, they'd spend weeks shadowing people, asking repetitive questions, and piecing together context from fragments. But if your procedures, past operations, comments, and decisions are all in one place? They can review everything before they even log in. They hit the ground running instead of spending their first month just getting oriented. At Epsilon3, we replaced the scattered mess of manuals, emails, and documents living in five different tools with a single integrated platform where all training and documentation is easy to find and actually use. When knowledge is accessible, confidence grows and errors drop. New team members contribute effectively from day one instead of ramping up for months. That's hundreds of training hours saved and faster time to productivity. Your systems should capture what people learn, not rely on them to remember it forever. How do you capture what your team learns so it doesn't disappear?

  • Manufacturing execution shouldn’t lag behind planning, but too often it does. In our latest blog, we break down what a Manufacturing Execution System (MES) is, how it bridges the gap between ERP and production, and why real-time visibility on the shop floor matters now more than ever. From guided work instructions to tracking every batch and quality check in real time, discover how MES drives efficiency, traceability, and compliance in complex operations.

    Teams evaluating tools often get stuck here: “Does it have every feature we want?” Fair question. Wrong priority. The teams hitting milestones consistently aren’t the ones with 100 features. They’re the ones who’ve eliminated: -Step drift -Missing part history -Untracked failures -Outdated procedures -Operator guesswork Epsilon3 covers the fundamentals that protect your schedule and your contracts. Perfect feature parity doesn’t win. Operational clarity does. Solve the big problems first; edge cases can always be built.

    I decided I wanted to work in space when I was in third grade. Not because someone told me to, but because I was always mesmerized and inspired watching the space shuttle launches. In the 1980s, every launch stopped the nation. Families gathered around televisions. Teachers wheeled TV carts into classrooms. (We also watched movies on VHS tapes.) When the launch director called liftoff, the entire country collectively held its breath. Space felt urgent, heroic and somehow both unattainable but yet possible, especially to a kid watching those solid rocket boosters ignite. Then we got good at it. So good that launch day became just another Tuesday. Even those of us inside the industry stopped watching every crewed mission (and I am guilty of it too). But it’s so easy to take this capability for granted. Until one launch made us remember. In 2020, the feeling returned. When Doug Hurley and Bob Behnken launched aboard Dragon, the world stopped to watch. Millions tuned in. It was the first time in nine years that humans launched to orbit from U.S. soil. In the middle of a difficult year, people called it the highlight of their year. The moment proved something critical: space can still capture global attention when we choose to highlight and celebrate it. That visibility matters. I see young people lighting up when they learn what we do. They ask questions and imagine themselves in mission control or on a crew headed to space (or even the moon / mars). But that excitement doesn’t sustain itself automatically. It requires effort from the industry, and the people working within it to communicate what’s happening right now, to share their experiences, and to celebrate the people doing the work. All the work we're doing today could end with this generation if we don't inspire the next one. Celebrating human space achievements isn’t about nostalgia or hype. It’s about making progress visible, showing that these achievements are real, and giving the next generation of engineers, mission planners, and astronauts something concrete to reach for. Spaceflight is still heroic. It's still hard. And it's still worth celebrating. Loudly. If you work in the industry, talk about it. Find someone who has no idea people are living and working in space, and tell them about the last launch you watched. The next kid who sees a rocket streak across their window won’t have to ask what it is. They’ll already know.
