Calendar and time planning and time reporting: both on the personal and on the group level.
In concert with tasks, processes, projects, other activities. No separate time planning or reporting is required.
All these can be applied for an any number of employees, subcontractors, vendors, too, as well as for non-human resources.
Non-human resource management is new and important: you can manage all the important resources the same way you are managing human resources. And: you can allocate rates (internal or external), time (planned and actual), invoices (customer and supplier), documents to each event or resource usage.
Non-human resources can be buildings, equipment, rooms, vehicles.
And: all these are accessible anytime, from anywhere. Flexible, firm-level calendar including workdays and non-working days and periods.
