While speed is of the essence to remove the risk to your business, moving too fast can result in mistakes that will further extend the completion date.
Being able to prioritize your tasks and identify those that are interdependent will help facilitate a smooth implementation of critical controls. This is where listing pre-requisite tasks in your project plan will pay dividends.
Set appropriate milestones that account for delays and setbacks so as not to have to rush to meet unrealistic deadlines. It is better to make mistakes early in the project when you have accounted for enough time resolve it, rather than rushing and discovering it at a more critical time.
