One of the few concerns I have had with Workfront is that, for larger projects, there is nothing that I see that relates to a project charter that should be created in the Initation process group or the project management plans that are major parts of the Planning process group. The intake and custom form has been helpful for projects that require less detail or planning, but not for the major initiatives. For those projects I try to keep to PMI (Project Management Institute) standards. Are you able to develop or account for those needs within Workfront? Also, if you don't have a PMP professional or PMI professional consultant, I would recommend that you have one be heavily involved/ consulted in Workfront development.
