The last two days, I researched my audience on the Internet. In my mind, I previously used to call them "professional trainers", i.e. people who give trainings, doing everything by themselves: from the idea for a new training until the training can be delivered. Hence, the product name is "trainer's joy".
However, during the research I learned that this process is usually called "instructional systems design" and that there are specialists called "instructional designers". OK, one more persona for this product.
And I learned that there are "teachers" at schools and universities who could also benefit from this product.
And I learned that in the e-learning space, there are "e-learning authors" who might benefit from the final output of Trainer's Joy!
Wow, suddenly I have 4 personas instead of one ... amazing!
