As Memorial Day weekend begins, XSITE pauses to remember the service members who made the ultimate sacrifice in service to our nation. We honor their courage, reflect on the freedoms their sacrifice helped protect, and keep their families and loved ones in our thoughts. This weekend, and on Memorial Day, Monday, May 25, 2026, we remember and honor. #MemorialDayWeekend #HonorTheFallen #NeverForgotten #ServiceAndSacrifice #Gratitude #Patriotism #MissionDriven #XSITE

🚀📈 XSITEing News!🚨 XSITE is proud to share that we have been awarded a new $400,000+ IWRP prototype effort supporting AI-enabled model-based systems engineering workflows.

It was great to attend the first Space Force Association – San Diego event at the University Club last night alongside our CEO, Jack Turner. It was an energizing kickoff for the local space community—bringing together government, industry, and mission-focused partners all aligned on advancing capabilities in the space domain. Events like this are a strong reminder of how critical collaboration is as the mission continues to evolve. We appreciated the opportunity to connect with leaders across the ecosystem, hear perspectives on the future of Space Force priorities, and explore where XSITE can continue to support. Looking forward to seeing this community grow and contributing to what comes next. #SpaceForce #SFA #SpaceDomain #XSITE

XSITEing Innovation! 🚀 From Alignment to Impact: This month, our Systems Thinking XCOMP, led by Chase Rodriguez, explored a challenge many teams face: problems that begin long before the work actually starts. Chase discussed the SIPOC framework, which focused on how teams can create clarity early by aligning on objectives, defining inputs and outputs, and understanding the full system before execution begins. His insights were incredibly valuable and directly support how we drive mission impact at XSITE. 👉 Read the full article below. #ThoughtLeaderHighlight #SystemsThinking #SystemsEngineering #Innovation #Leadership #XSITE
