Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the product as a work order service line item in the mobile app.
The Field Service Mobile app allows technicians to add products as service line items directly to the work order, which can automatically update inventory if the product is tracked. Option B is incorrect: calling the dispatcher is inefficient and delays real-time updates. Option C is incorrect: asking the customer to add parts via the portal is not a standard workflow and does not ensure inventory accuracy. Option D is incorrect: manual recording and later adjustment risks inventory discrepancies and defeats real-time tracking.
