Where are you going to find the time to recruit? Do you have a full-time job without recruiting? Do you already work plenty of hours each week? Where is the extra time going to come from?
From the week(s) you lose when you have an opening and have no idea where to look. That is the worst vantage point to be recruiting from. We will call that the desperation approach.
From the time you spend working with, trying to fix and finally replacing the wrong people hired, because you did not have time to recruit according to a plan. Nothing is more expensive than hiring the wrong people and dealing with the consequences. Think about the last time you hired the wrong person and the time you wasted.
From the time you will save creating synergies as you implement the plan. You will not implement a plan merely because it represents good business sense. The day after you make the commitment, the fires will start and the plan goes on the shelf. The only way that you will follow through with implementation is if you receive short-term benefits that help you with other aspects of the job.
