What was the essence of dual power? Why did it lead to disorganization of the country’s economic and political life?

1) In 1917, two parallel opposing centers of state power emerged in the country:
Provisional government
councils of workers ‘and soldiers’ deputies.
This political system is called dual power.
2) Both the provisional government and the Soviets tried to “take over” all the functions of power in the country by issuing orders that directly contradict each other. So, for example, the Petrosovet tried to introduce an 8-hour working day, control the supply and supply of food, interfered in affairs at the front. Of course, in such conditions, there was a disorganization of the country’s economic and political life.
