In the case of two-week iterations, there will be some components of courseware that cannot be developed in a single iteration.
For example, it takes time to make a video. The person or object of the video capture session has to be scheduled and the video crew has to travel. Or consider the time involved in custom-programmed complex interactions with equipment that behaves like the actual equipment.
In these cases, we start in one iteration but do not get credit for the work item until an iteration or two later when we finish.
Lean-Agile meant that we did not have to plan out every detail of the video shoot months before the dates would be known. It saved overproduction waste on guessing when the person would have been available.
That flexibility allows the team to move more quickly through the planning phase and into designing and developing courseware.
