A bar-chart is a very popular scheduling tool. It is easy to prepare, easy to explain and easy to understand. It basically describes the amount of time (work-hour or work-day) needed to perform a task including the total time to complete the whole project.
Other than time, resources such as labor, material, equipment and cost can also be loaded into the bar-chart. This is called a value-added bar-chart. With this type of bar-chart, S-curve is usually used as an illustration of the resource usage or cost analysis. It plots the cumulative value of any point at the time of the analysis.
However, there are occasions where projects are monitored and controlled using work-day based or time-loaded S-curve only. This is especially true at the beginning of a project or in smaller scale projects as often being practiced in Malaysia. One of the reasons could be because of easy monitoring without the needs of checking and analyzing resource utilization and cost incurred.
The time-based S-curve planners or users often find it difficult to plot the S-curve directly in the scheduling software they are using. This is because there are no specific menu or feature in most scheduling software on how to create this time-based S-curve because most scheduling software were designed to track time and cost or resource together instead of separately.
Based on the great demand on this issue, I have written an illustrated e-book that describes the steps involved in creating a time-based S-curve manually, as well as directly plotting it in Primavera Project Planner® software.
If you are interested to buy the e-book, please read the instruction provided in the side column. Thank you.
