If you are a wise man, you always add holidays to the project plan. your national as much as holidays of your customer and your best-cost-country supplier. at least two weeks between X-Mas and next year, so that nobody expects you to deliver in that period.

Every summer I’m facing the summer vacation problem: how to plan if one – two – three – many people are on the beach, but customer still expects to have proper stand in and deliverables per schedule? may I add two to three vacation weeks to my project plan?

I need to think about. if you have any suggestions or experiences, please share!
