If you're in the Chicago area, you'll want to check out the Chicago Product Management group, organized by Bernhard Kappe.
ChiPMA, The Chicago Area Product Management Association, is all about helping Product managers and related fields to get better at designing, building and launching digital products and services. Modeled after the Silicon Valley Product Managers Association (SVPMA, www.svpma.org), ChiPMA's meetings expose members to current trends in innovation, product strategy, product marketing, development approaches and the latest tools and technologies.
On April 15, join them for Rapid Product Design: Six Visual Techniques for Quickly Creating and Communicating Innovative Ideas.
