If a single member of staff is assigned to four tasks that run at the same time then the Workload view predicts 32 hours to be worked on a single day, which is obviously not going to happen. What we are actually saying is that the member of staff will be working on four task during an 8 hour day.
Ideally, a task would be scheduled for a duration, say 2 weeks and then resources allocated to the task would be scheduled to take part for a fixed duration, eg. 40 hours (1 week). Ideally then the programme would also be levelled so that the standard 8 hour day is not exceeded unless the task duration (i.e. the 2 weeks) is a constraint, in which case the daily hours worked increase to accommodate this.
This is how MS Project deals with it (which I appreciate is intended to be more detailed) but as it stands, the resource/workload management aspect of Wrike is not effective for us.
Is this something you can help with?
