This question already has an answer here:
What is the problem that is solved by Domain Driven Design?
I understand what Object Oriented Programming brought and see the issues it addressed and how, and in what aspect/scenaria, it made the live of a developer easier. But I so far failed to see the big picture of what DDD does bring us. For sure this is due to the fact that I am just starting with DDD and maybe it is something I will just know at the end (after working with it for some years). But if not and it is possible to summarize the big picture in some sentences please share them with me.
What I got so far:
DDD helps to define a common language to discuss a software project for example. To understand what is happening in a domain, e.g. how the business works, what operations are possible and under which conditions. What data has to be stored and how it should be grouped.
Is this the big picture? I think there is more to it but I cannot yet see it.
There exists a similar question What is Domain Driven Development in practical terms?. However this question has a different focus when asking what DDD is while I would like to learn to what problem DDD is the solution. One given answer to that is really excellent and does also include possible answers to my question. I cannot judge whether this answer includes the complete answer to my question but right now my intuition tells me it does not.
