- top-down planning, where planning only takes place for project and maybe component,
- bottom-up planning, where plan figures for a project or component (only) arise from the plan figures for tasks and sub-tasks.

Time Planning Method
We distinguish a generic top-down time budget and a derived bottom-up time budget.
# Time Budget Category Description, Remarks
...
| Time Budget | Description | Remarks |
|---|---|---|
| top-down | planned time is set on this level |
...
| possible on the level of component and project | |
| bottom-up | time is retrieved from lower levels |
...
The logic is as follows:
...
This way you proceed - separately! - for every level. It is very important to understand that all derived results displayed are always results from all entries of exactly one level deeper.
However, technicall you might need to go through the whole tree. Recursive tree-search? We need to discuss the possible number of knots in the tree. Performance issues!
7.2.3.3 Examples
The following examples show the way we can enter generic time budgets and the way the derived budgets are calculated on every level:
