I do follow a structure when it comes to my scenes, but only because my scenes tend to ramble and I can forget where I'm going with them. I go in 2 parts: first is the actual scene and the second is the sequel. I lay them out like this, in accordance with K.M. Weiland's book 5 SECRETS OF STORY STRUCTURE:
Setup: The POV, where it is, what the weather's like, a note about the previous scene, and whatever else is needed to remind me of where I am.
Goal: Character's goal for this particular scene. I've had goals vary from, "Stab the beast in its soft spot at the precise time" to "Get some sleep" so the goal can be as simple or complex as you want/it needs to be.
Conflict: What's preventing the goal from being achieved? Again, this could be anything: physical impediments (the beast is really damn fast), mental (my anxiety is going a mile a minute and I can't sleep), emotional (I feel really bad about killing the beast and don't want to do it), you get the idea.
Disaster: The fallout of the goal not being reached. Once more, this could be anything. It can be as big as missing the target and the character getting injured or as little as someone needing the character and sleep is not achieved.
The sequel is the immediate followup to the scene. Again, I follow Weiland's formula and lay them out like so:
Reaction: It's the character's emotional and physical reactions to the disaster and the previous scene. I use this as a springboard to lead into the next scene, with the reaction affecting not only the following categories of the sequel, but also what's going to happen in the next scene. So, if the character missed the hit and is injured, I would put here their emotional state (panicked, afraid, angry) and physical state (OWOWOWOWOWOW) as well as how they react to those states.
Dilemma: This is the decision the character has to make. For example, they can either attack the beast again or they can try a new tactic or they can run. The main idea is that there has to be a choice that the character grapples with for a moment (or more.)
Decision: Character chooses a side in the Dilemma and follows through with it.
I usually add a section for notes after this, about how the decision affects the end of the scene, or just to jot down ideas or things if I think of them later. I know that structure this rigid isn't for everyone, it just works well for me due to my personal issues with anxiety, perfectionism, and need for order. I can attest that it has helped me immensely in getting my book into a cohesive whole, as well as giving me opportunities to build tension/suspense by chaining several scenes together.
Hope this helps, Garmr!
