DR. Simon in in lecture mentioned us about the project objectives. He stated that the objectives should be achievable, understandable, and affordable.
What do you think the project objectives should be in any case.

According to me the main and basic project objective should be a successful outcome, that is the change or effect it is going to cause. In simple terms they are goals or can say buisness objective that you want to accomplish. Though there is slight difference between goal and objective, goal is a higher level statement and objective being lower level statement. Formulated Project Objective should have a description of projects outcome and effects, participatory process, it has to be accepted by stakeholders.
