UX strategy follows your product development cycle timeline. A good rule is to always do research early and often. The cost of fixing a problem post-development can be up to 100x that of fixing it beforehand.^[1]

The tests you need to run will differ depending on the stage:

• Discovery: At this stage, you need to learn about the market for your product and its potential users. Consider using methods like generative interviews, diary studies, ethnography, field studies, and focus groups.
• Validation and testing: At this point, you typically have a prototype to test. The goal now is to understand if your design works for users. Key methods to test this include qualitative usability testing, tree testing, first click testing, task analysis, A/B testing, and accessibility testing.
• Post-launch: Once you've launched your product, it's important to keep the research going to ensure that your solution is still working. You can track it with surveys like NPS or your product's analytics.
