Good planning (and actually sticking to it) is something you always need. As we have seen, some implementations may require a lot of actions to be done, some of them before the new functionality is implemented, some during the implementation process, and some others right after the implementation process is completed. Some implementations can even be done progressively, so they could last weeks or even some months.
Everything has to be planned and scheduled so that all needed work for the implementation of the functionality is ready on the chosen date to go live.
Take the to-do list written in the previous section and determine the following for each action:
Determine when the action has to be performed:
Before the implementation date
During the implementation process
After the implementation process is completed
Estimate the time that will be needed to complete the action
Establish relations between actions (some actions have to be completed so that other actions can start;...
