Abstract

A method of scheduling a multi-task project includes identifying critical and para-critical tasks of the project. The critical tasks are ranked in a chronological order and displayed. The para-critical tasks are displayed adjacent to the displayed critical tasks. Target finish dates are established for the displayed critical tasks and the displayed critical tasks are monitored. Actual completion dates of the displayed critical tasks are displayed adjacent to the displayed critical tasks. The target finish dates for all subsequent displayed critical tasks are adjusted to reflect any variance between the target finish dates and actual finish dates.

Claims

1. A method of scheduling a project consisting of a plurality of tasks, said method comprising the steps of:

identifying critical tasks of the project;

identifying para-critical tasks of the project;

displaying the critical tasks in a visually perceptible manner with the critical tasks ranked in chronological order;

displaying the identified para-critical tasks in a visually perceptible manner adjacent to the displayed critical tasks;

establishing target finish dates for the displayed critical tasks and displaying a target finish date for each of the displayed critical tasks adjacent to the respective displayed critical task;

monitoring performance of the displayed critical tasks to establish actual completion dates of the displayed critical tasks;

displaying the actual completion date of each displayed critical task adjacent to the associated displayed critical task upon completion thereof; and

adjusting the target finish dates for all subsequent displayed critical tasks to reflect any variance between the target finish date and the actual finish date of a displayed critical task.

2. The method according to claim 1 additionally comprising the step of notifying parties responsible for completion of at least one of the displayed tasks of the target start date thereof.

3. The method according to claim 2 wherein said step of notifying parties responsible for completion of at least some of said displayed tasks includes keeping said parties advised of any revision thereof.

4. The method according to claim 1 wherein said project is a construction project and wherein said plurality of tasks comprise tasks related to said construction project.

5. The method according to claim 1 wherein each para-critical task is displayed next to a critical task having a start date closest to the start date of the para-critical task.

6. The method according to claim 5 wherein said displayed para-critical tasks are ranked according to a preferred order of performance with respect to one another and with respect to displayed critical tasks, with each para-critical task being carried out on an as soon as possible basis.

7. The method according to claim 1 additionally comprising the step of adjusting target finish dates for said para-critical tasks responsive to adjustment of the target finish date of one or more of said displayed critical tasks.

8. The method according to claim 2 wherein said tasks are displayed in a visually perceptible manner on at least one scheduling sheet, said step of notifying parties responsible for completion of at least one of said displayed tasks comprising transferring selected information from said at least one scheduling sheet to a target start schedule and distributing said target schedule to a selected party or parties.

9. The method according to claim 1 wherein said critical tasks are displayed in a first column and said para-critical tasks are displayed in a second column alongside said first column.

10. The method according to claim 9 wherein said target finish dates are displayed in a third column disposed proximate to said first and second columns.

11. The method according to claim 1 additionally comprising the steps of recording and displaying the period of any variance between the target finish date and the actual finish date of a displayed critical task.

12. The method according to claim 1 additionally comprising the steps of recording and displaying the reason for any variance between the target finish date and the actual finish date of a displayed critical task.

13. The method according to claim 1 additionally comprising the steps of identifying and combining a plurality of overlapping critical tasks and displaying the combined critical tasks in a visually perceptible manner as a single compound critical task.

14. The method according to claim 1 additionally comprising the steps of identifying a plurality of overlapping critical tasks and accounting for the overlapping critical duration in schedule computation.

15. The method according to claim 1 additionally comprising the step of comparing a plurality of visually perceptible displays of target finish dates and actual finish dates of critical tasks at intervals over the period of time of said project for evaluating the performance of parties performing the critical tasks during said project.

16. The method according to claim 1 wherein said critical tasks and said para-critical tasks are displayed in a visually perceptible manner or typed or printed scheduling sheets.

17. The method according to claim 1 wherein said critical tasks and said para-critical tasks are displayed on a computer screen.

18. The method according to claim 1 wherein the step of adjusting the target finish dates for all subsequent displayed critical tasks to reflect any variance between the target finish date and the actual finish date of a displayed critical task is carried out by a suitably programmed computer.

19. The method according to claim 1 additionally comprising the steps of recording and displaying identification of those responsible for any variance between the target finish date and the actual finish date of a displayed critical task.

20. The method according to claim 1 additionally comprising the step of adjusting a project schedule by schedule off-set to facilitate accountability analysis.
