INCOSE Webinar 157 Invitation

Clients and Customers often believe they know the solution they prefer but may not understand the problem they need solved. As a consequence, their requirements may be non-existent, incomplete, or incorrect. Requirements elicitation may be inadequate to actually realize a correct and complete set of requirements. This presentation explains how to generate requirements when there aren't any or they are not complete, consistent or correct. Checklists for engaging clients and customers are included.

We have moved to the ZOOM platform for INCOSE webinars. One significant change is that we recommend that attendees join audio now using the ZOOM platform audio (Voice over Internet). This worked very effectively for the recent (virtual) International Symposium.
