ms project training - Effort driven tasks

Hi Martha

Thanks for your question. Effort driven scheduling is active for new tasks by default in Project. It takes effect once a resource (or resources) have been assigned to a task. Any increase or decrease to the amount of resource assigned to the task will trigger Project's Effort Driven Scheduling. You will find Project increases or decreases the duration of your task in response to the changes you make to your assignment.

For example if you have a two day task and assign one resource 100% to it and then you assign a second resource Project will conclude that if it takes one person two days to do the task, sending a second person means the same amount of work can be done more quickly and the duration will be halved down to one day.

I hope this is helpful - do let us know if we can be of further assistance.

Kind regards,

Andrew
