Validating software estimates step by step process of carbon dating
However, the downside is that details might be missed without a detailed review by the project team.Let’s say you’re responsible for upgrading your application’s hardware and software layers.The risk is that the application software doesn’t work on an upgraded software layer due to a conflicting API or compiled library.The challenge is in all those pesky details that impact your project.All these tasks can then be logically grouped into categories that make up each work package.The bottom-up approach results in a more detailed schedule, but it’s also a time-consuming approach compared with the top-down task planning approach.
Project planning can rely on both top-down and bottom-up planning techniques.
And, it helps define the specific resource skills needed during key phases of the project in order to get a more accurate schedule.
The tradeoff of using a bottom-up approach is that it requires more time.
Then, the sum of these estimates and task dependencies within each work package determine the total cost and timeline for the project schedule.
This technique is useful for developing detailed project budgets, schedules and monthly forecasts.
