Missing milestones creates setbacks a lot of the time which can be harmful to a company rather than beneficial. I understand when you say that it might be beneficial to a company because your working on perfecting the device before it gets marketed. However, missed milestone in a company can lead to loss of money. My dad is a supervisor in New York City and he was the project manager of a year long project which had a deadline set for October 15th. If he was not able to get his team to complete the project by that deadline then the company he works for will have to pay another corporation $100,000 each day the project was delayed.Their was no room in that kind of schedule to miss milestones because the consequences were very harsh. When I worked on a year long project whenever we missed milestones it wasn’t a good news for my team. It meant that we had less time to complete other milestones.
