The best thing about planum is that it comes with an excellent customer support team who guide you through every step of your project, from development to implementation stage till end-user acceptance! It has been very easy working in this tool since they provide all documentation needed as well help during installation process (even though I am not proficient enough). Nothing much so far but everything seems good at first sight which makes me feel comfortable using their product without any hesitation or doubt until now when i have used them couple months ago only then one problem came into my mind - They don't give license key after purchase unlike other tools like Teamwork etc where we just need some time before getting our own keys/license codes required by us while deploying application internally within organization!! Highly recommended if someone looking forward having user friendly interface & customization features along side strategic analysis capabilities than go ahead otherwise.
