Building A Minimal Viable Product (MVP)
February 18, 2016

A good example of the value of using a minimal viable product (MVP) is our pilot project funded by the Center for Child Injury Prevention Studies (CChIPS). Our team conducted a series of focus groups and a national survey to determine how best to use digital communication technology to improve child restraint system (CRS) installation.

This formative research served as the foundation for the development of a mobile, smartphone-based MVP to support parents in correctly installing CRS. This mixed methods research included focus groups with 25 parents from the Philadelphia area followed by an online survey to over 1,000 parents nationwide.

Survey Results

What we found out is that parents are:

  • unsure of when to move their child to the next level of car seat based on weight and age
  • find car seats physically difficult to install
  • confused about car seat check programs and other national resources
  • unsure of how to check if the car seat is being used correctly
  • interested in mobile tools to support installation in real time

All the parents and caregivers in the study owned a mobile device, and over 90% owned smartphones, with most using their phones to access the Internet. They told us that they would use a CRS installation application during each phase of their child’s transition. When asked for top suggestions for the tool, they recommended:

  • installation videos
  • troubleshooting tools
  • car seat check clinic finders
  • tools to find the right CRS for their child

Based on these insights, we developed a “clickable” prototype to gather additional feedback from parents and caregivers. Although it looks like an app on your phone, it’s a set of design pictures that show how the app would be organized and how it would be used. This MVP was a much less expensive approach to ensure we were creating an app that would be useful and valuable to parents and caregivers

Test and Then Test Again

The next steps in the project are to further develop and test the mobile tool in a randomized trial to evaluate its effectiveness in improving CRS installation and use.

There’s no magic formula for determining the “right” MVP for any given technology or tool; it’s something that the research and development team needs to agree upon. The ideal is to build just enough to obtain concrete feedback from the target audience and key stakeholders.

If you’re a researcher, program manager, or app developer, we encourage you build on your formative research findings, use a multidisciplinary team with expertise in behavior change, technology and user-experience design, and gather user input all along the development process, including the MVP. With this additional feedback and research, you can create a mHealth tool that is both usable and valuable for your intended audience.
