PLAN. COMMUNICATE. LEAD.
Quite often when you run projects certain situations happen, which present a risk of not achieving the deadline. And often you have only one plan how to achieve that deadline. What happens then is that people end up in situations, when they have to explain why some things can not be achieved and how much delay is expected.
But life might get a bit easier if you have a Plan B – a kind of back up plan, which you can use and still be able to achieve your deadline and provide the promised deliverables. Your Plan B can be a temporary solution, which can be brought to life and serve until actual solution is being delivered. Or your Plan B can be a permanent solution which can be implemented and help meet the deadline instead of the one, which brings delay. Think about that and keep this in mind, so you are perceived as a creative and resourcefull PM, who finds solutions for complex situations and does not create more problems.
