Microsoft Project is the most-used software to organize, plan and manage your business job, increasing the efficiency of your work, people and cost management.
First define the working days and the all the personal and shared holidays, and then all your objectives, defining milestones, deadlines and constraints. Define all the people involved on these, adding name, contacts, email and additional data, and then assign to each one the most proper job.
Link different objectives if they have to be done in order. Once the plan is defined, Project helps you rearranging your organization, indicating overlapped jobs, deadline not respected, and all the people overloaded or on holidays for a determined period.
Project is indeed a great software for any business management.
