Topic 43 – Use of Net Promoter Score Measures to Evaluate MSLs

A couple of my clients have discussed the use of the Net Promoter Score lately so I thought I would address it in my blog.

Quick background:

The concept of the Net Promoter Score was introduced in a Harvard Business Review article in 2003 by Fred Reichheld of Bain & Company. The net promoter score is measured by asking a single question: “How likely are you to recommend the company/product/service to a friend or colleague?” and is usually measured on a 0 to 10 basis. Scores of 9 and 10 are called Promoters, scores of 0 to 6 are Detractors and scores of 7 and 8 are called Passives. The Net Promoter Score is calculated by subtracting the percentage of customers that are Detractors from the percentage of customers that are Promoters.

People like the net promoter score because it is a simple measure of loyalty and when it is paired with an open ended question that asks why the particular score was given, it provides insight into what is important to the customer.

So, does the Net Promoter Score (NPS) provide value to MA? My research has not been able to find a single academic or metric-driven study on the use of NPS in MA specifically related to MSL activity. Common sense says this approach should be helpful but for now anyone using this approach is in experimental mode.

In MA the NPS question is often modified to be:

• "How likely are you to recommend engaging with [COMPANY X] Medical Science Liaisons to your colleagues or peers?” OR
• “How likely are you to recommend working with [MSL NAME] from [COMPANY X] to your colleagues?

PRO’s of Using NPS in MA:

• Brief nature of survey makes it suitable for rapid deployment immediately following MSL interaction to avoid the “blending” affect that occurs when HCPs are asked about MSL performance on a standard survey often weeks after their last interaction
• Relatively inexpensive to conduct compared to other market research
• NPS can help gather insights into what an HCP value in an MSL interaction, if open ended questions are employed as well

CONs of Using NPS in MA:

• Message vs Messenger: When an HCP recommends working or engaging with an MSL is that recommendation based on the quality of the content of the interaction or the interpersonal qualities of the MSL herself or himself?
• Not comparative: NPS does not give insight into whether HCPs recommend your MSLs any differently than they recommend competitor MSLs. Perhaps HCPs in a particular therapeutic area simply recommend all MSLs the similarly regardless of company.
• Not clearly actionable: If your NPS drops from one month to the next, what action should be taken? Some insight might be provided by the open ended questions but those responses are often only provided by the most dissatisfied

Given the inherent challenge, it is my opinion that the NPS is still a worthwhile measure, but it needs to be gathered as a part of a broader market research effort to give it the context that can help tease apart the reason for the scores.

The most effective NPS is gathered as soon as possible after the last interaction. In the case of MSLs, a system should be established to seek this guidance directly after a contact has been noted in the company’s contact management system. And, like all market research with HCPs, participation is highly impacted by compensation, so sufficient compensation must be offered to ensure enough participation to make the measure meaningful.
