Cash flow forecasting

As important as estimating the overall costs and benefits of a project is the forecasting of the cash flows that will take place and their timing. A cash flow forecast will indicate when expenditure and income will take place (Figure 3.2).

Figure 3.2 Typical prrxluct life cycle cash flow.

We need to spend money, such as staff wages, during the development stages of a project. Such expenditure cannot be deferred until income is received (either from using the software if it is being developed for in-house use or from selling it). It is important that we know that we can fund the development expenditure either from the company's own resources or by borrowing from the bank. In any event, it is vital to have some forecast of when expenditure such as the payment of salaries and bank interest w ill take place and when any income is to be expected, such as payment on completion or, possibly, stage payments.

Accurate cash flow forecasting is not easy, as it generally needs to be done early in the project's life cycle (at least before any significant expenditure is committed) and many items to be estimated (particularly the benefits of using software or decommissioning costs) might be some years in the future.

When estimating future cash flow s, it is usual to ignore the effects of inflation. Trying to forecast the effects of inflation increases the uncertainty of the forecasts. Moreover, if expenditure is increased due to inflation it is likely that income will increase proportionately. However, measures to deal with increases in costs w here work is being done for an external customer must be in place - for example index linked prices where work involves use of raw materials - sec Chapter 10 on contract management.

Table 3.2 illustrates cash flow forecasts for four projects. In each case it is assumed that the cash flows take place at the end of each year. I'or short-term projects or where candidate projects demonstrate significant seasonal cash flow

patterns it can be advisable to produce quarterly, or even monthly, cash flow forecasts.
