A large computer task becomes manageable when its deliverable, inputs, and dependencies are visible. Splitting by arbitrary time blocks or app names can create a longer list without clarifying the work.
Begin with the deliverable
Describe the finished result in a form someone can inspect: a reviewed document, exported image set, deployed page, or reconciled spreadsheet. Record the acceptance checks that matter. Then list existing inputs: source files, approved references, account access, and any decision that must already be made.
Work backward through dependencies
Ask what must be true immediately before the final step. If publishing requires a verified preview, and preview requires an export, those are real ordered dependencies. If research and image selection can happen independently, do not force an invented sequence.
Write each step as an action with one primary output: “Extract the three approved figures from the source sheet,” then “Insert figures and captions into the draft.” Note which file or web resource each action consumes. If a step still contains several unrelated verbs, split it again.
Build the working set for the next step
Open only the material required by the current action and confirm it is the correct version. Keep source and output windows distinguishable. Under one Wallo goal, to-dos and existing windows can sit side by side, but each to-do is not directly bound to one window. Wallo does not provide subtask trees, dependency enforcement, automatic decomposition, or file storage.
