Igniting Innovation: Tips, Sparks and Ideas for Acting on Innovation

How Many People Should Be Responding To My Research Surveys?

Posted by Greg Lemmon on Nov 5, 2015 10:02:20 AM

When leading innovation, you’ll want to have a system for doing research. Research doesn’t have to be in the form of surveying customers, but asking a potential customer if they’d purchase a new offering is typically done at some point in the innovation process.

The question we get asked quite frequently is how many customers do I need to survey. My answer is that it depends.innovation and consumer researchI know, not the answer you’re looking for, but it’s the truth. The problem is that you need to plan and budget for future surveys about ideas that haven’t been created yet. It depends, isn’t helpful, so here are two things to consider:

  1. How confident do you want to be? The more confidence you want to have in the survey’s results, the more people you should survey.
  2. How much variance have you seen in past surveys? This can’t always be applied, because when leading innovation you will have to test new ideas with new customers. But the take away is that the more variance the questions have, the more respondents you want.

With estimates for confidence and variance you can use statistics to calculate the exact number of responses you should be collecting.

Bigger picture. I recommend having a system for testing ideas throughout the innovation process. With new ideas, test lots of them with small sample sizes. You don’t need a lot of confidence here, just enough to justify working on an idea. Systematize this testing, so there is always time and a budget to test new ideas. As ideas get more defined and are ready for development you can retest them with larger sample sizes. This takes more effort, but you’re doing this with less ideas and gaining the confidence you need to give the go ahead for development.

Your job as your organization’s leader is to create a system that enables your employees to collect the responses they need. Organizations that have a system for research surveys will also have the data needed to calculate sample size.
