A crisis is any event that occurs suddenly, which causes a destabilization of an organization (State, company..) and which is accompanied by a shortage of raw materials and/or components necessary for its proper functioning.
The price of raw materials or components increases sharply. This causes bottlenecks in the supply of factories and in some cases a depletion of stocks.
The consequences are exploding delivery times and prices, which are directly reflected in finished products such as cars or construction.
In extreme situations, factories can be shut down and companies can experience financial problems, most often with respect to cash flow.
