𝐓𝐡𝐞 "𝐈𝐭 𝐖𝐨𝐫𝐤𝐬… 𝐔𝐧𝐭𝐢𝐥 𝐈𝐭 𝐃𝐨𝐞𝐬𝐧’𝐭" 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 𝐢𝐧 𝐑𝐞𝐬𝐞𝐚𝐫𝐜𝐡 𝐃𝐈𝐘
When your perfect new creation betrays you:
You spent weeks designing it. You tested it a dozen times. Built to solve a very specific research problem, it ran flawlessly on the bench. The data looked clean, the signals were stable, and you finally breathed a sigh of relief.
Then, halfway through your most important experiment… it failed. No warning. No smoke. No obvious reason. Just silence from the device that worked perfectly yesterday.
Why Does This Happen? Here are some common reasons:
1 - 𝐓𝐡𝐞 𝐏𝐡𝐚𝐧𝐭𝐨𝐦 𝐆𝐥𝐢𝐭𝐜𝐡
Loose wires, cold solder joints, or power fluctuations can cause intermittent failures. What worked on your bench might fail in the field due to vibration, humidity, or temperature changes.
2 - 𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞 𝐆𝐫𝐞𝐦𝐥𝐢𝐧𝐬
A firmware bug might only trigger under rare conditions (e.g., after 72 hours of logging). Your code seemed fine—until it wasn’t.
3 - 𝐓𝐡𝐞 "𝐈𝐧𝐯𝐢𝐬𝐢𝐛𝐥𝐞" 𝐍𝐨𝐢𝐬𝐞
Electrical interference (from motors, Wi-Fi, or even fluorescent lights) can corrupt signals. Your setup was noise-free… until you moved it next to that incubator.
4 - 𝐄𝐝𝐠𝐞 𝐂𝐚𝐬𝐞𝐬
You tested for all the scenarios you could think of, but there is always something lurking out there to throw you a curve ball. A combination of seemingly insignificant factors that when combined provide a scenario you never considered.
5 - 𝐓𝐡𝐞 𝐇𝐮𝐦𝐚𝐧 𝐅𝐚𝐜𝐭𝐨𝐫
Maybe a lab mate borrowed your device, plugged it in wrong, and didn’t tell you. Or you forgot to recalibrate after swapping a component.

Lost time: Repeating experiments wastes weeks.
Lost trust: If your tools are unreliable, colleagues (and reviewers) question your data.
Lost sanity: Debugging without a clear cause is maddening.
Equipment: For effective testing and debugging, expensive equipment is needed and expertise
Consider these next time you are wrestling with the build vs buy decision
