Searching a cell and setting another cell

I have a spreadsheet and on column A there are about 20 different project status (e.g - roadmap, mandate, startup, feasibility, definition....)

I want column B to be set to a vaule based on what was in column A.

For example - if column A is = to roadmap set column B to roadmap, if column A = startup or feasibility or definition then set column B to Planning. If column A = Build or deploy then set column B to Building.

Any idea how to acheive this?

Thanks!
