> Not just search for truth and fact, but use these truths and facts to develop ways that benefit people.

Wait, when did "how to use these truths" become part of science?? How you use science to develop things that benefit people (or organizations) is normally called engineering! Science is normally concerned only with finding useful facts about the world. There are some exceptions, like when you're using the scientific method exactly to figure out what benefits people (or any living organism), for example, using pharmacology to develop drugs that help people. But I would argue that even then, the main concern of pharmacology is to figure out what kinds of drugs have what effects on humans in certain conditions - i.e. it fits perfectly into the definition of "searching for truth and facts".

How you apply that knowledge science gives you to solve problems that affect society is called policy - and policy, while can be analysed using the scientific method, is normally not itself science. It's hard to use the scientific method to study policy, though, because there are far too many factors involved in anything to do with large groups of people, and far too little room to do experiments on them.

Here you said it: "useful". The meaning of the word "useful" is a philosophical/political consideration.
