It is easy to get bogged down in details when discussing topics like engineering data management (AKA product data management or PDM). Sometimes it is good to step back and look at the big picture. For me, the details of PDM are the bricks in a building; the building is Time to Knowledge.
I define “Time to Knowledge” as the time it takes someone to get the specific accurate information needed to answer a question. The typical day in engineering has hundreds of moments which trigger a Time to Knowledge event. Such questions as “What is the status of yesterday’s engineering change request?” or “Which document is the right revision, and where is it?” are specific questions that require specific answers available in your existing engineering data. If the answer is quickly accessible, productivity is enhanced. If the answer is an uncertain quest away, the human tendency too often is to find an imprecise workaround or to avoid the subject completely.
