Product manuals are always being chased by change
A single flagship product line can involve thousands of components, hundreds of drawings, and dozens of process documents. Every engineering change requires sales quotes, service manuals, and BOMs to be realigned.
Service knowledge is privately held
When a machine fails onsite, newer engineers often call the veteran who has seen it before instead of checking documentation. Once that veteran retires, the knowledge disappears.
Sales pricing falls behind reality
Pricing strategy and optional configurations may already have changed, while frontline sales is still quoting from a manual that is months out of date.
Cross-functional teams live in document hell
R&D, sales, and service each maintain their own version of product information. The same component can have three versions of truth, and nobody is confident in any of them.
