Any planning begins with an assessment of the availability of resources. The second step will be to calculate the necessary resources. Before the era of economic cybernetics, the first two steps were carried out manually. The collection of necessary information was based on statistical reporting. This led to unreliability and irrelevance of the information collected. Building a cross-sectoral balance on unreliable and irrelevant information devalued its value for evaluation and calculation. That is why the cross-sectoral balances necessary in strategic planning are not applied in the practice of public administration, if they are based on an outdated method.
