Implementing Buffer Management
(Prioritizing and Managing Tasks)
|
As we discussed before, absence of task level priorities is a major shortcoming in traditional project management. Now that we can issue clear, uniform and stable task priorities using Rule 3 (tasks consuming the most buffer get the highest priority), what is the management process around them? This is the subject of this minute.

Remaining Duration Reporting
During execution, Task Managers provide daily estimates of how much longer it will take to finish their tasks-in-progress. With this simple information, we can calculate the ratio of buffer consumed for a chain of tasks compared to the work completed in that chain. This ratio is then used to calculate task priorities and provide Task Managers a report of all current and upcoming tasks in order of priority.
(Tendencies to procrastinate and not report early finishes are also curbed. When the buffer consumption ratio is high and visible to everyone, it reminds Task Managers to make and report progress.) |

Resource Assignment
Task Managers assign resources to current tasks in order of priority. If resources are not enough to handle even the red tasks (tasks that have crossed the threshold of acceptable buffer consumption), overtime and other such decisions are implemented. |

Task Preparation
After taking care of current tasks on their plate, Task Managers turn their attention to upcoming tasks. They make sure that all necessary preparations like getting approvals, drawings, materials etc. are made so that tasks can be executed without interruption when they arrive. |

Quick Issue Resolution
By interacting with resources for Remaining Duration updates, Task Managers discover unexpected problems quickly. They now have a chance to resolve them in a timely manner on an ongoing basis instead of fighting fires towards the end. |

Reminder: Don’t Pressurize Resources to Meet Planning Estimates
Otherwise you will soon be back to square one. |
