Question

the concept of a digital thread is most closely associated with which of the following? physical document storage reducing the complexity of product designs isolation of product teams a linear process of product development traceability of product data across the lifecycle question 9 (1 point) why is it difficult to implement and maintain a digital thread across the full product lifecycle? products rarely change after design, so continuity is unnecessary engineering and manufacturing data are rarely needed together most engineering teams already use fully integrated tools that require no further data alignment semantic interoperability and version control are only achieved through proprietary data formats the amount and complexity of data generated at different stages can vary

Explanation:

A digital thread is about connecting and tracing product - related data throughout its lifecycle. For the first question, physical document storage is not related to the digital concept. Reducing product design complexity, isolation of product teams, and linear product development processes are not the main ideas of a digital thread. The key is data traceability. For the second question, products often change after design, engineering and manufacturing data are frequently related, most teams don't have fully integrated tools, and semantic interoperability and version control are not just about proprietary formats. The varying amount and complexity of data at different stages make implementation and maintenance difficult.

Answer:

First question: Traceability of product data across the lifecycle
Second question: The amount and complexity of data generated at different stages can vary
