Answer:
effectiveness and efficiency
Step-by-step explanation:
The two main things that you should focus on are effectiveness and efficiency. When evaluating implementation you need to make sure that what you are thinking of implementing will actually solve the problem that the organization is having, which is the entire reason for implementing the solution in the first place. It needs to be effective as a solution. When selecting the proper algorithm you need to focus more on efficiency, you already know that it will provide the correct solution but now you need to see which solution would be the fastest and therefore most efficient choice.
