The best sequence is to start with a problem and find a solution. It's far less good to start with a tool and then find problems that more or less can be solved with it.
For managing budgets I recommend a bookkeeping program or (on a small scale) a spreadsheet. To achieve a goal you start working and organizing and lobbying, not making diagrams. That's a sure way of not reaching your goal.
