In the business world, there are always deadlines, and missing them can often have great consequences, such as losing clients, profits, etc. But even more importantly, deadlines, and whether you make them or miss them, reflect on your reliability. With a few strategies, you can make sure you always make the deadline.
Approach the deadline like the theatre. Theatre productions always have non-negotiable deadlines. No matter what happens, the job gets done and the show must go on.
Take in the whole picture. Assess the details, and give yourself the time and resources to make sure you can accomplish everything to the level of quality needed.
