Where time and knowledge leak away in service
The after-sales support team lives on tickets that arrive from everywhere - email, web form, phone, chat. Someone has to read each one, work out what it's about, and route it onward. A good share of them are the same questions with an answer that already exists somewhere - in a manual, in documentation, in the history of past tickets. But reaching that answer takes an experienced person who knows where to look.
And here's the crux. Diagnosing an issue from the customer's description, recognizing that a problem has already come up before, complete complaint documentation - all of it rests on the memory of specific people. As long as they're there, it works. Once they're gone, you start from zero. On top of that, there are tickets that nobody links together individually, but which together point to a systemic product problem - a signal that gets lost because no one aggregates the history.
What can realistically be built
A first-line assistant that answers recurring technical questions by pulling the answer from the plant's documentation and ticket history - and leaves the hard cases to a person. Diagnostic support that, based on a description of the symptoms, suggests likely causes and next steps, drawing on how similar cases were solved before. Ticket classification and routing, so requests land directly with the right person. Complaint documentation consolidated in one place. And pattern analysis - a tool that pulls a recurring product problem out of hundreds of tickets and flags it to the quality or design department.
At the core of every one of these tools is the plant's knowledge base. That's what you build first, and then you layer functions on top of it. The side effect is that knowledge stops being the private property of your best technician and becomes a company resource.
