OP's question: Cash flow problems arise when more cash is flowing out of a business (e.g. for raw materials, wages, expenses etc) than is flowing in (e.g. from sales). In order that the business can survive/ meet its commitments, it will borrow, short term, from a bank
to cover the difference between income and expenditure.
please help.......how to draw organisational charts?
Adding on to furqan's answer, if the case study/question indicates the firm is "international" then it's possible you'll have to draw an organisational chart for 2-3 countries to get full marks.
