I am trying to describe a hierarchy, starting with a plan, which is composed of a set of goals. Each goal is also composed of a set of "steps" or things that need to be done to complete the goal. However, I don't want to use the word "steps" because that word has an implication that the "steps" have to be done in a particular order, which is not true in this case.
Can you suggest a word that is a sub component of a goal that doesn't have this implication of order?
For example, the plan might be "make the yard look amazing". One goal might be "fix the floral borders." One step of this might be "select flowers suitable for a north facing border", another might be "select flowers suitable for an east facing border", then other steps might be "Plant the north border" and "Plant the east border". Although there are some temporal relationships there, some are entirely independent, but all must be completed to finish the goal. So I am looking for a word for the sub components of the goal that is free of any implication of temporal (or for that matter topological) order.
