Just one bad patch can cause key systems to fail, disrupting your teams and, ultimately, your customer experience. While I was checking out at a supermarket self-service machine, the screen suddenly froze and then dreaded blue screen of death appeared. A nearby staff member quickly came over and, with a bit of a sigh, said it was the third time that day this happened. While I’ll never know for certain whether a patch was the only cause, businesses want to minimize these types of issues.
