agency set its campaign budget based on what we wanted to achieve with the promotion
objective and task method which is the most rational budget-setting method. The
first step of the method is to define the precise objectives; secondly, we must
establish the tasks that must be achieved
to accomplish these objectives; and finally, to approximate the costs of executing
these tasks. The sum of the expenditures is the recommended/ assumed promotion budget.  The problem with the objective and task method
is that, it is usually hard and unclear to distinguish which tasks will be
achieved from the stated objectives (Kotler and Armstrong, 2006, p.441).
