I recently posted about how usability testing can slow down launch but speed up success. But usability testing is just one of many elements of user experience research, with others including the ethnographic field studies made popular by Ideo, the A:B testing becoming standard for web 2.0, customer feedback, focus groups etc. With so many tools at your disposal, which user experience research tools should you use and when?
Jakob Nielsen recently posted about this topic, and concluded that it depends on what phase of product management you are in. For startups, my summary of his work is below:
Ideation: At the very beginning of the process you are looking at new ideas and opportunities. In this phase, aside form the founders vision, ethnographic field studies, focus groups, diary studies, surveys and data mining of webwide behavior can all be useful. Most startups will not have access to proprietary user data of existing products to identify additional opportunities.
Pre-launch: Once you’ve settled on a product idea and are working towards (beta) launch, you want to improve design and functionality as much as possible to minimize risk and maximize the likelihood for a successful launch. In this phase rely on tools such as cardsorting, paper prototype and usability studies, participatory design, desirability studies and field studies (including closed alpha launches to “friendlies”) to improve the user experience.
Post-launch: Once you’ve pushed the product out you will have live data that you can use to compare the product both to itself and to its competition. In this phase, usability benchmarking, online assessments, customer emails, surveys and A/B testing will be your primary tools
Nielsen provides some additional frameworks to differentiate when to use different forms of user experience research in his post. The site is a good resource about user experience in general.
