Celoxis vs WorkOtter PPM

Celoxis is a great option if you are looking for an affordable, easy to use, easy to integrate project manegement solution. It is very powerful for waterfall project management. I evaluated more than 15 platforms and could not find any with a close evaluation in terms of cost-benefit to Celoxis. Of course there are more powerfull tools, for 10 times the price. So far, for project management, there hasn't been a requirement I haven't been able to solve with some work.It really lacks features for Agile methodologies, even if it provides a Kanban view, so far it doesn't provide and additional agile artifacts. If an organization has already reached a very mature project management practice and needs to improve on program and portfolio management, Celoxis won't provide any useful feature. If the organization has the resources (skills and time mostly) to develop some workflows and customization, it might work but with a limit. Hopefully Celoxis addresses these features in the near future.

I know it works well for IT but not sure how it would work for construction. I think construction has a different set of needs.
