Follow these steps to add buffers to your project
1. Make sure your project has the status "Not Started"
The Project should not have been released yet. Make sure that the project has the status: "Not Started" via: Project Properties -> Status: Not Started.
2. Make sure that you know what buffers you would like to add
There are three types of buffers that could be used within Lynx projects:
- Project Buffers
- There is only one project buffer at the end of a project.
- Feeding Buffers
- There can be multiple feeding chains, which can have their own feeding buffer
- Milestone Buffers
- A deadline defined for a task is considered to be a Milestone;
- The chain leading to a task with a milestone will have a milestone buffer.
For this article, we have the following example project with a deadline:
As you can see, task 4 (End Prototype) has a milestone at the 14th of September. You can add a milestone yourself by selecting the tab constraint within the bottom of your screen and fill in the Deadline date at the right side.
3. Choose the CCPM configurations
There will be three buttons in the top right behind the text CCPM. The button that can be found at the far right side is to open the CCPM Property dialog. Within this dialog box, you can select the bufferpercentage that you would like to add ánd which buffers you would like to add via the checkbox. You can multiselect the buffers we described above: the Feeding, Milestone and Project buffer, see figure:
-- Note: If you have no deadline within your project, you can try to add a milestone buffer, but that will not appear. --
4. Add your buffers
There are two ways to add the buffers into your project:
- The Insert Buffers button at the screen that you just opened.
- Directly via the CCPM button with the '+' sign
Within this dialog, you find the same settings as within the CCPM Property Buffer Creation, but with an additional button: Create Buffers. Press the button and the buffers will be added to the project: Operation has completed.
Now you know how to add buffers to your plan. If you want to read more about the background of the theory behind prioritizing based on buffers, please read Understanding (CCPM) Priority Behavior.
