Query regarding possible status of submitted paper
I doubt that you are quite aware of the workflow of that particular journal. The related wisdom found on Academia SE appears incorrect too. AFAIK (from personal experience as handling editor for an elsevier journal), the editorial system here is a two-tier system: there is the editorial board and there are specialist/handling editors.

The handling editor deals with the reviewing and submits their decision to the editorial board (or the editor in charge), who in turn base the final decision (as communicated to the author in the decision letter) on the handling editor's suggestion. So, in your case


the handling editor has obtained the reviews and submitted their decision to the editor/editorial board; what this decision may be, you cannot know: it can be 'reject', 'accept without change', or 'revise' (most likely);
the editor(ial board member) in charge has not yet processed this case.


This is mostly likely because they are away on vacation or conference/work related leave. If you don't get a decision within a few weeks, you may inquire with the editor in chief or the clerk.

Note also that with this process the status always changes from 'under review' to 'decision in process', regardless of whether you will be asked to make revisions.
