What Is the Duration of an Activity?

A distinction is drawn in project management and consequently also in Merlin Project between two planning methods: resource-based planning and time-based planning. For the former, the fields "Work..." are responsible. In the latter case, permanent fields are used.

Time-based planning can be used in the following cases, for example:

• If the effort for a resource cannot be determined
• if external resources are used and no detailed financial calculations are performed for them
• if the workload is to be modified by different values for work and duration
