Good customer services: product knowledge

The idea

Product knowledge means staff understanding the features, benefits, uses, prices and limitations of what they sell, so they can match a customer's need to the right item. A sales assistant in a phone shop who knows battery life, storage and contract terms can ask questions, explain trade-offs and recommend confidently. Knowledge is built through induction, supplier training, manuals, shadowing experienced colleagues and using the products. It supports good customer service because accurate advice reduces returns, avoids misleading claims and builds trust, while poor knowledge causes wrong recommendations, frustration and lost repeat business. Staff should also know when to check with a colleague or manager rather than guess. Assessed through explanation of how knowledge improves service and analysis of consequences when it is missing.

• Use a named business context so your explanation is applied rather than generic.
• When analysing, state the consequence for the business, not just for the customer.
