The correct answer to this open question is the following.
Although there are no options attached, we can say that step in the IDEAL model that the beginners are neglecting is the Diagnosing step.
While beginners tend to jump right into proposing solutions, experts tend to spend time thinking about the underlying causes of the problem and interpreting it from different perspectives. This is because experts know that they need to spend some time trying to find the correct causes that originated a problem. This allows them to understand the origin of the problem, not only the symptoms. When experts understand different perspectives and view the issue through different angles, they will have more chances to make a better decision and act correspondingly.
After the Diagnosing phase of the model, it comes Establishing, Acting, and Learning.

The problem starts already earlier:wildlife experts can only estimate the number of species in the world generally!
This is the case because there are simply too many species, and it takes time to documents them; because some areas (ocean bottom for example) are very hard to access and because sometimes it's hard to know whether we're talking about a new species or a variation within the same species.
so if we even don't know how many species there are, it's even harder to know how many are endangered.
