Paddling Estimates
Paddling estimates are conducted to either add more time or cost to a project due to the project’s lack of appropriate and exact estimates. It is implemented as a safety measure. Nevertheless, I do not agree with the assertion that it is conducted as a safety measure since it is inappropriate and unprofessional for project managers to have paddling estimates in their projects. Therefore, in my opinion, paddling estimates should not be used since they may add unnecessary time and costs to the project undertaking.
Project Buffer
As critical chain scheduling purports, adding a project buffer to the entire project is an additional estimate, including the effort and time used to generate the project schedule. The project buffer is normally set at 50% of the project critical chain duration (Kerzner, 2017). I don’t think that project is important. Critical chain scheduling is responsible for the resource constraints and purports to limit multitasking of the resources in making project schedules and accounts project and feeding buffers to ensure timely completion of the project.
Ethical Consideration Of The Slack And Buffer
Slack is the difference between the project’s current completion date and the latest date the project can be completed date. The latest date an activity can be completed without causing a slip to a critical path is known as Late Finish (Kerzner, 2017). Slack helps ensure that ethical responsibilities are met for the project.
A buffer is an activity or time strategically put in place on the critical path before the agreed completion date. The buffer helps maintain an agreement by allocating time in which no work is scheduled to take place, but it can be utilized if delays interfere with the critical path.
PMI Perspective
The PMI perspective in relation to paddling is that it ensures the additional time and costs are based on the PMI’s code of ethics. Thus, it ensures paddling occurrences are accounted for.
