Hi Community,
I wanted to share a few practical lessons learned from a personal ServiceNow project I built in my Personal Developer Instance as part of my self-learning.
Rather than focusing on features, my goal was to understand how real-world ServiceNow solutions should be designed.
Key takeaways that might help others:
• Design before build – spending time on table structure and relationships saved a lot of rework later
• Avoid overusing Business Rules – Flow Designer made logic easier to maintain and debug
• Keep configurations simple – fewer scripts = easier upgrades
• Logging matters – even in small projects, logs and audit fields help with troubleshooting
• Document as you go – screenshots + notes helped me explain the project clearly later
This was a self-initiated learning project, not production work, but it helped me better understand how scalable ServiceNow implementations should be approached.
I’m sharing this in case it helps others who are learning or building projects in a PDI.
Question to the community:
What’s one lesson you learned the hard way while building ServiceNow solutions?
Looking forward to learning from your experiences.
