First Claim
1. A method for managing a project schedule, said method comprising:
- developing a float profile area chart having a float profile with a float gradient for at least one non-completed activity within the project schedule to pictorially assess schedule viability;
calculating a schedule risk index (SRI) score to qualitatively assess a risk level associated with the project schedule, wherein calculating the schedule risk index score includes comparing changes from a recent schedule update relative to a previous schedule update based on a plurality of weighted factors to tabulate the SRI score, the SRI score being indicative of risk the project schedule will miss a scheduled completion date;
measuring a plurality of schedule quality metrics and aggregating the values for the metrics to provide an indication of the project schedule being manipulated by a scheduler;
recording historical trends for the schedule quality metrics and weighted factors across at least two update intervals; and
measuring schedule performance by trending early starts and early finishes for the project and a relative slippage occurring from the previous schedule update to the recent schedule update.

Abstract
A project schedule is managed by developing a float profile area chart having a float profile with a float gradient for at least one non-completed activity within the project schedule to pictorially assess schedule viability. A schedule risk index (SRI) score is calculated to qualitatively assess a risk level associated with the project schedule. Schedule quality metrics are measured and the values for the metrics aggregated to provide an indication of the project schedule being manipulated by a scheduler. Historical trends for the schedule quality metrics are trended across at least two update intervals, and schedule performance is also measured, e.g., by trending early starts and early finishes for the project and a relative slippage occurring from the across schedule updates.

23. A tangible computer-readable storage medium having embodied thereon a computer program configured to, when executed by a processor, manage a project schedule, the medium comprising one or more code segments configured to:
-
develop a float profile area chart having a float profile with a float gradient for at least one non-completed activity within the project schedule to pictorially assess schedule viability; calculate a schedule risk index (SRI) score to qualitatively assess a risk level associated with the project schedule, wherein calculating the schedule risk index score includes comparing changes from a recent schedule update relative to a previous schedule update based on a plurality of weighted factors to tabulate the SRI score, the SRI score being indicative of risk the project schedule will miss a scheduled completion date; measure a plurality of schedule quality metrics and aggregating the values for the metrics to provide an indication of the project schedule being manipulated by a scheduler; record historical trends for the schedule quality metrics and weighted factors across at least two update intervals; and measure schedule performance by trending early starts and early finishes for the project and a relative slippage occurring from the previous schedule update to the recent schedule update. - View Dependent Claims (24, 25)

26. A system for managing a project schedule, comprising:
-
a processor; a display unit operatively coupled to the processor; and a memory operatively coupled to the processor, the processor being configured to; develop a float profile area chart having a float profile with a float gradient for at least one non-completed activity within the project schedule to pictorially assess schedule viability through the display unit; calculate a schedule risk index (SRI) score to qualitatively assess a risk level associated with the project schedule, wherein calculating the schedule risk index score includes comparing changes from a recent schedule update relative to a previous schedule update based on a plurality of weighted factors to tabulate the SRI score, the SRI score being indicative of risk the project schedule will miss a scheduled completion date; measure a plurality of schedule quality metrics and aggregating the values for the metrics to provide an indication of the project schedule being manipulated by a scheduler; record historical trends for the schedule quality metrics and weighted factors across at least two update intervals; and measure schedule performance by trending early starts and early finishes for the project and a relative slippage occurring from the previous schedule update to the recent schedule update.
