Ahead of time...

Microsoft always plan ahead of time.. actually they have no choice, they have thousands of employee and their activities can't just stop like that..


the project manager must be having headaches all the time... that is why they need sebatica kind of vacation... human resource department also very important, as well as documentation department..

this also proves that when you have long term plan, the organization will then to be bigger because at any single time, not everyone will be off for holiday, someone must be working.
