A tech support engineer at an EDA (Electronic Design Automation) company in the 1980s was asked to quickly verify a software update on a 9-track tape before it was hand-carried to a major defense contractor customer in Dallas. When the engineer installed the tape and found it caused the machine to fail, they realized the tape had never been properly tested. The engineer then confronted the test department, leading to a printed memo outlining the 'top ten reasons' the untested tape nearly shipped, and the shipment was ultimately halted.

Why it matters

This incident highlights the importance of thorough software testing, even for seemingly minor updates, to avoid catastrophic failures for major customers. It also shows how a proactive tech support employee can play a critical role in catching problems before they lead to lost business and damaged reputations.

The details

The tech support engineer, who specialized in application tools for printed circuit board design, was asked by their manager to quickly verify a bug fix on a 9-track tape before it was hand-delivered to a key defense contractor customer in Dallas. Despite initial resistance from the operations manager who controlled access to pre-release tapes, the engineer was eventually able to obtain the tape and install it, only to find the machine failed to boot. The engineer then tested the tape on another machine, which also failed, realizing the tape had never been properly vetted by the test department.

  • The day before a new software update was set to release, the engineer was asked to verify the bug fix.
  • The engineer installed the tape and found the machine failed to boot.

What they’re saying

“I've often thought about what I did next. I could have been diplomatic, gone to the test group and told them, 'Hey, you might want to test this tape before we ship it tomorrow,' so that they could handle it internally.”

— The Tech Support Engineer

“Instead, I went to the test group and said, '***, you signed off on shipping a tape you didn't test at all!?!?'”

— The Tech Support Engineer

“The operations manager stopped by my office to make sure I knew that she was 'only kidding' when she made me grovel to get the tape.”

What’s next

The test department was required to implement more rigorous software testing procedures to prevent similar incidents from occurring in the future.

The takeaway

This case highlights the critical role tech support staff can play in catching major software issues before they reach customers, as well as the importance of thorough testing protocols, even for seemingly minor updates, to avoid costly failures and lost business.
