US Classification:

717102, 717100, 717105, 705 8

Abstract:

A method on a computer for providing critical chain-based project management is disclosed. The method includes generating a list of sequential time periods for a project comprising a plurality of tasks and calculating a number of tasks for each time period. The method further includes generating a graphic that visually indicates the number of tasks for each time period and a priority of each task and providing the graphic to a user.

US Classification:

717101000

Abstract:

A method on a computer for providing critical chain-based project management is disclosed. The method includes receiving at least one project plan for a project comprising a plurality of tasks and calculating a task priority for each of the plurality of tasks based on the at least one project plan. The method further includes receiving at least one sub-task for a first task of the plurality of tasks and assigning the at least one sub-task a task priority identical to the task priority of the first task. In one alternative, the method further includes receiving a new task priority for the first task, assigning the new task priority to the first task and assigning the new task priority to the at least one sub-task of the first task. The method may also include an interface to allow starting of sub-tasks only when the parent task is started.

Appl. No.:

12/610209

Inventors:

Ajai Kapoor - San Jose CA, US
Ravi Shankar - San Jose CA, US
Xiangting Yuan - Pleasanton CA, US
Anthony H. Hoang - Milpitas CA, US
Prakash K. Pati - San Jose CA, US

Assignee:

International Classification:

G06Q 10/00

US Classification:

705301

Abstract:

Some embodiments provide a system for determining an aggregate delay associated with a task attribute value. During operation, the system can receive a set of projects, which include completed projects and currently executing projects. Next, the system can determine buffer consumption amounts associated with task chains in each project. A task chain can be a sequence of tasks in the project's task dependency network which ends in the project buffer. The buffer consumption amount associated with a task chain can be the amount of the project buffer that would have been consumed if the tasks in the task chain were the only tasks in the project. Next, the system can select a set of task chains based at least on the buffer consumption amounts. The system can then aggregate task delays for tasks in the set of task chains that are associated with the task attribute value.

International Classification:

G06F 9/46

US Classification:

718100, 715772

Abstract:

Some embodiments of the present invention provide systems and techniques for collecting task status information. During operation, the system can receive a status update for a task from a task manager through a GUI. Next, the system can determine whether the first status update for the task indicates that the task is delayed. If the status update indicates that the task is delayed, the system can request the task manager to indicate the help needed to resolve the task delay. Next, the system can receive a help needed descriptor from the task manager. Subsequently, the system can receive another status update for the task from the task manager, wherein the status update indicates that the help specified in the help needed descriptor is no longer required. Next, the system can determine an amount of delay associated with the help needed descriptor.

International Classification:

G06F 9/46

US Classification:

718100, 715772

Abstract:

Some embodiments of the present invention provide systems and techniques for determining a start delay and an execution delay for a task. During operation, the system can receive a status update for the task which indicates that the task has started execution. Next, the system can receive a second status update for the task which indicates that the task has completed execution. The system can then determine the start delay for the task by: determining an actual start time using the first status update; and determining a difference between the actual start time and the task's suggested start time. Next, the system can determine the execution delay for the task by: determining an actual execution duration using the first status update and the second status update; and determining a difference between the actual execution duration and the task's planned execution duration.
