Timeboxing is a Planning technique common in planning projects (typically for software development), where the schedule is divided into a number of separate time periods (timeboxes, normally two to six weeks long), with each part having its own deliverables, deadline and budget.

Although typically associated with software development, it seems an ideal model for me to use over the 4 week production timeline. While not taking the form of boxes, I have drawn up a time table for my sketchbook containing 2 goals (deliverables) per week, all clearly labeled with their due date. The budget does not factor in to my needs so I have omitted it.
This should ensure a tighter work pipeline by allowing me to see at a glance where I should be at any given time.
