Structured Instrument
Net Promoter Score (NPS)
Customers rate their likelihood to recommend the product on a 0-10 scale, are categorized as promoters, passives, or detractors, and the net score is derived by subtracting the detractor percentage from the promoter percentage. The process includes a follow-up question to capture the reasons behind the rating.
