Starting with one of the broadest types of consulting, strategic consultants assist with the upper-level decision-making in a business.
This is definitely a big-picture-thinking type of job, generally advising at the highest level within a company (think C-Suite, Directors, and Senior Managers).
Since this is a broad role, it can fit in a variety of sectors. The more specific the role, the more the title will change. Some examples are:
-- Financial Strategy Consultant
-- Environmental Strategy Consultant
-- Business Strategy Consultant
