Approach each question in an RFT by writing a headline that encapsulates the key benefit you are presenting in your answer. This will help you to focus your argument.
For example, in a question about customer service many people start by talking in generalisations about how seriously they treat it, their Customer Service Policy, or how they focus on TQM. The problem with this approach is that the benefits for the purchaser are not immediately obvious and busy evaluators will not bother searching for them.
Instead, think about Customer Service in your organisation - what do you do differently and it what ways do you add-value for your clients? This will give you your "headline" and the evaluators something they can score.
