| 27 | +## Step 1: Create a Project Instance |
| 28 | +Initialize a new project instance using the following code: |
| 29 | +```java |
| 30 | +Project project = new Project(); |
| 31 | +``` |
| 32 | +## Step 2: Create a Task Baseline |
| 33 | +Create a new task and set its baseline using the following code: |
| 34 | +```java |
| 35 | +Task task = project.getRootTask().getChildren().add("Task"); |
| 36 | +project.setBaseline(BaselineType.Baseline); |
| 37 | +``` |
| 38 | +## Step 3: Display Task Baseline Information |
| 39 | +Retrieve and display task baseline information such as duration, start date, finish date, and more: |
| 40 | +```java |
| 41 | +TaskBaseline baseline = task.getBaselines().toList().get(0); |
| 42 | +System.out.println("Baseline Start: " + baseline.getStart()); |
| 43 | +System.out.println("Baseline Duration: " + baseline.getDuration()); |
| 44 | +System.out.println("Baseline Duration Format: " + TimeUnitType.toString(TimeUnitType.class, baseline.getDuration().getTimeUnit())); |
| 45 | +System.out.println("Is it an Estimated Duration?: " + baseline.getEstimatedDuration()); |
| 46 | +System.out.println("Baseline Finish: " + baseline.getFinish()); |
| 47 | +``` |
| 48 | +## Step 4: Check Interim Baseline and Fixed Cost |
| 49 | +Check if the baseline is an interim baseline and retrieve any fixed costs associated with it: |
| 50 | +```java |
| 51 | +System.out.println("Interim: " + baseline.getInterim()); |
| 52 | +System.out.println("Fixed Cost: " + baseline.getFixedCost()); |
| 53 | +``` |
| 54 | +## Step 5: Print Timephased Data |
| 55 | +Print timephased data associated with the task baseline: |
| 56 | +```java |
| 57 | +System.out.println("Number of Timephased Items: " + baseline.getTimephasedData().size()); |
| 58 | +for (TimephasedData data : baseline.getTimephasedData()) { |
| 59 | + System.out.println(" UID: " + data.getUid()); |
| 60 | + System.out.println(" Start: " + data.getStart()); |
| 61 | + System.out.println(" Finish: " + data.getFinish()); |
66 | 62 | } |

| 66 | +## Conclusion |
| 67 | +Managing task baselines is essential for project management, allowing you to track deviations from the planned schedule. With Aspose.Tasks for Java, this process becomes streamlined and efficient, enabling better project control and delivery. |
| 68 | +## FAQ's |
| 69 | +### What is a task baseline in MS Project? |
| 70 | +A task baseline in MS Project is a snapshot of the initial planned schedule for a task, including its start date, finish date, and duration. |
| 71 | +### Why is managing task baselines important? |
| 72 | +Managing task baselines helps in comparing the planned schedule with the actual progress of the project, facilitating better tracking and decision-making. |
| 73 | +### Can I modify a task baseline once it's set? |
| 74 | +Yes, you can modify task baselines in MS Project to reflect changes in the project plan. However, it's essential to document any deviations from the original baseline. |
| 75 | +### Does Aspose.Tasks support other project management functionalities? |
| 76 | +Yes, Aspose.Tasks offers a wide range of features for project management, including task scheduling, resource allocation, and Gantt chart generation. |
| 77 | +### Where can I find support for Aspose.Tasks? |
| 78 | +You can find support for Aspose.Tasks on the [Aspose.Tasks forum](https://forum.aspose.com/c/tasks/15), where you can ask questions and interact with other users. |
