The user interface could be improved. Because you can say it is not the best on the market. There are other products with better interfaces. It is not like the ERP (Enterprise Resource Planning) interface that you can create yourself. The product needs to be more flexible in creating a user-friendly interface for the customer.  

Making it flexible more in terms of integration with other products outside of IBM products would be a welcome addition. The product can already integrate and has flexibility, but there is opportunity for even more improvement in this way.  

We have a process flow and we have multiple applications using the same platform. For example, application A uses the PX 1.0 and another application has to use 2.0 or 3.0 because 1.0 has been used by application A. That's the reason that the user asks why they are using version PX 3.3. They want to use whatever they want. 

They need more monitoring capability. When the flows go through, a lot of what my clients are asking for is to be able to monitor a transaction from end-to-end. I have no way of monitoring the transaction inside the DataPower, so I have to start at the next step.

The solution needs to stabilize its UI capabilities and other features within the product. Lately, there have been big swings in UI. It started in 7.5 and 7.5.1. In 8.0 they completely changed the solution's UI capabilities and it threw everyone off. In 8.5 and 8.5.5 they introduced client-side and human resources. Now they seem to be returning back to the original UI capabilities.

The solution lacks acceptable stability.

The solution's technical support could be better.

It would be helpful if the solution was able to loop in the VPN as well within its general capabilities. Users should be able to implement their own choice of technology, be it Java or any other code.
