In extreme cases, a problem of this type may only come to light when the
system is commissioned. Clearly, this would not have happened if the initial
stages of the development model had been rigorously followed.
Steps (3) and (4) can be considered to be the 'design' phases. The first of
these (development of an algorithm) involves conceptualizing the means of
solving the problem. This is often done with the aid of a flowchart or a data
flow diagram and usually involves breaking down the problem into a number
of smaller steps (processes). Figure 4.5 shows the set of standard symbols that
are commonly used in flowcharts.
