We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

    Thank you for your suggestion. DSNI070I message has been extremely helpful for debugging the early stage of FTB issues. Now that the duplicate information has been recorded in the statistics trace, and also planning the improvement in display command, we will consider either reduce the frequency of the message or remove all together.

    This message clutters the MSTR making it difficult to see potential/actual issues, and fills up the job log. My preferences are #4 then #2. Thank you.
