An alternative is to use a computer to display bar charts at several levels of detail. For resource planning and material ordering purposes the detailed operations required for each structure can be shown on one chart, and these can be summarized into one bar on another bar chart, which in turn can be used to represent progress on the project as a whole. Critical linkages between operations can be fed into the program as for network diagrams (see Section 14.5 ), and the resulting critical paths and ‘floats’ can be derived. Adjustment to a detailed bar chart – perhaps due to some delay or extra work – is automatically reflected in the overall summary bar chart display. Of course the operation of such software requires investment in the time and the use of skilled operators, so the cost may only be justified for a large complicated project. Another form of progress chart is to mark up the cumulative value of work done on a graph as illustrated in Fig. 14.3. However, to ensure that such a chart Fig. 14.3. Financial progress chart. The forecast line shows that the contract is likely to be completed about 3 months late at £0.3 million excess cost
