Submit your papers, panel proposals, and tutorial proposals by going to the submission website.
Also, please use your network outside of INCOSE to encourage more submissions. In case you do not have it, here is the link to the official Call for Submissions
Remember, the initial submissions will be the ones reviewed by your INCOSE peers& fellows for acceptance or rejection. So it's important that you make them as close to final as possible before the November 3 deadline.
