With twice the product in half the time™ being a generic goal for industry, what exactly is going wrong in today’s industrial environment? What stops or delays improvements in product delivery, despite embracing practices from Lean and Six Sigma? Why does it take years to get a new product out of the manufacturing plant? This Advisor seeks to demystify one of the myths that surrounds Agile product development: the myth that one way to optimize people’s time is to have them work on large batches: design the whole product, build a full prototype, test a full prototype, and design manufacturing only when the prototype passes all tests. The thinking is that this will reduce task-switching, eliminate mistakes, and achieve the desired high utilization of people. By planning the work in phases, we believe we can prevent problems in the phases that follow.
