Overall Satisfaction with IBM watsonx Code Assistant Portfolio

We POC'd the product for IBM watsonx Code Assistant Portfolio for Z. The use is for Mainframe understanding and modernization. This was to understand how our mainframe components interact and how we can understand what the dependencies are within our different applications. It also provided visual representations that can document what is happening across our pieces. The last IBM watsonx Code Assistant Portfolio piece was done in VSCode to Transform code.

Pros

  • ADDI - Static Analysis
  • Query-able Data
  • Good integration with IDE (VSCode)

Cons

  • The other UIs of the different phases (Refactor and Transform)
  • The usability of the tool and how it can hook into our existing systems.
  • Time Savings from Understanding
  • Broader understanding
  • Impact to non technical users.
ADDI, the understanding phase. As mentioned in the other questions this is where we found the most value. IT was able to deterministically graph out all the dependencies for the specific mainframe components uploaded. With this the team was able to get a great understanding of how our components worked together and an inventory of our current pieces.
Fully graph out our mainframe components. We could do this with other tools in pieces but not at the scale of which this product could. This allows us to understand faster than before and allow us to do a lot more than we could from the understanding point of view. I would recommend this aspect of the tool .

I would recommend for understanding your Mainframe components not for the GenAI piece involved from just my experience. The explanations were not up to the quality we wanted but its deterministic side provided a lot of value for different members of my team. The visuals would be great. I am not sure where it currently stands.
