MetricStream sales showcase all html pages and create hallucinations in demos. Before you buy ask them to demo all the features that needed by your company. Also make sure at least some business users access their workflow for an hour. If the application works without crashing then you can buy, but I can guarantee that it will not hold for so long.
Most important, they use something called Appstudio and they tell you you can build your workflows on fly. If you believe and buy the tool your remaining life you will work on solving Appstudio problems than using MetricStream products.
Another item, they showcase their applications very responsive and every page loads within 3-5 seconds. First check volume in the system and then ask them to show 5 seconds.
