What do you like best?
One stop shopping for Kanban, Gantt, File Sharing, Comments, tight integration with Planview (owner of Projectplace).
This was a quantum leap above the SharePoint lists and Excel project plans we were going to use before being introduced to this.
What do you dislike?
Had some problems with very large Excel documents (13mb) not coming through properly. Putting the Gantt view behind the highest paywall is a bit of a blatant money-grab, but that would only effect non-corporate users.
We tried to expand the use of this tool here, but it was not viewed as being favorable to other tools that more tightly integrate with the code/build/test cycle.
What business problems are you solving with the product? What benefits have you realized?
Projectplace was used to coordinate the rollout of a different tool into our corporate IT environment. By using a tool outside of our own network it made it much easier to collaborate with the vendor without having to invest in VPN connections so they could access our internal SharePoint sites.
