Numbered sequence of all scenes with location, time, and plot point — between treatment and beat sheet. Your shooting schedule blueprint.
You're sitting in the director's office, the script in front of you, and you need an overview: How many scenes? Which ones take place in the same location? Where are the logistical bottlenecks? The Step Outline is your tool for exactly this. It lists each individual scene numbered, noting the location, time of day, and the core plot in one or two sentences. No more than that: that's enough.
Unlike the treatment, which elaborates narratively and outlines dramatic arcs, here you maintain conciseness. Unlike the exposé, which only sketches the major turning points, you capture the complete scene structure — all transitions, all location dependencies visible on one or two pages. This is your roadmap for production planning: the Line Producer needs this list for locations and crew deployment. The Production Manager plans the shooting day blocks based on it. You yourself immediately recognize if three scenes take place in the same diner — shoot them together, save yourself the setup and teardown. The editing music will follow from this sequence later; now it's about physical feasibility.
In practice, you note the minimum: Scene 5 — Morning Gold (Kitchen) — Day — Anna prepares breakfast, finds the receipt. That's it. Some directing teams number differently than the original script (if scenes are combined or cut), which quickly leads to confusion. Therefore, use a numbering convention that everyone understands: either keep the original numbering, or create a separate production numbering and document the assignment. This is a constant point of friction, especially with multiple script versions.
You will refer to this list repeatedly during pre-production — scenes are dropped, scenes are added, locations change. Every change affects the Step Outline and thus the budget and schedule. Therefore, it is not a task of diligence, but a strategic document. Some directors create it in parallel with the treatment as a check: does the Step Outline tell the same story? If not — what is missing in the dramaturgy? You need this clarity before the first discussions with production. A poorly thought-out Step Outline means chaotic shooting days and budget shortfalls later.
