Struggling to Model Data

I've got a s/s of data which is a list of risks that have 1 or more actions (1:m). However each risk can then be assigned to one or more goals and vice versa a goal can have many risks attached  - (M:N)
I've broken this using a bridge table with a combined key.
When I try link it back to the actions, this then becomes a M:N relationship.

I need to be able to drill grom goal, throguh risk into action.

I have no measurable facts as such so all teh tables are Dimensions but valuses such as target date, etc can change making them SCD.

Should I just be creating one big table with all the columns and then hvaing redundant data within it  (effectively mulitipl rows for a single action, linking it back to the risk and then the relevant goals). Effectively, a risk could have 4 actions and be attached to 3 goals, effectively creating 12 rows for the risk/goal/ action combination (if i've done my maths right)

Any ideas would be appreciated
