# Project Management Timeline and Milestones

## What is the Project Management Timeline?

The Project Management Timeline is a visual timeline view within each project that displays activities and milestones on a calendar-based Gantt-style chart. It provides a comprehensive view of your project schedule, helping you visualize when activities are planned, track progress, and coordinate team work.

## Accessing the Project Management Timeline

To access the Project Management Timeline:

1. Navigate to **Projects** in the main navigation.
2. Click on a specific project to view its details.
3. In the project view, click the **Project management** link on the right side menu, or select it from the project tabs.
4. The Project Management Timeline page opens, displaying all activities in a calendar view.

## Understanding the Timeline Interface

### Main Timeline Components

The Project Management Timeline consists of several key elements:

**Activity List (Left Side)**
- Shows all activities in your project as a scrollable list
- Displays activity names and links to edit each activity
- Can be sorted and filtered using controls at the top

**Calendar Timeline (Right Side)**
- Displays dates horizontally from the current date forward
- Shows a visual representation of when activities are scheduled
- Allows you to click on any date to create new milestones
- Activities appear as colored bars on the timeline

**Timeline Controls**
- Located at the top of the timeline view
- Include zoom levels (1, 2, 3) to adjust calendar granularity
- Edit, Sort, and Assign buttons for bulk operations
- Zoom slider to adjust timeline scale

**Timeline Scale**
- Shows date numbers across the timeline
- Displays weeks and months
- Can be zoomed in or out for different perspectives

## Creating and Managing Milestones

### What are Milestones?

Milestones are key dates or checkpoints on your project timeline that mark important events, deliverables, or decision points.

### Creating a New Milestone

To create a milestone directly from the timeline:

1. On the Project Management Timeline page, click **New milestone** button in the toolbar, or
2. Click any date number on the calendar timeline in the right section
3. The milestone creation dialog opens
4. Enter the following details:
   - **Milestone name** — A descriptive title (e.g., "Design Phase Complete", "Client Approval")
   - **Date** — Automatically pre-selected based on where you clicked
   - **Optional description** — Add context for the milestone
5. Click **Save** to create the milestone

Milestones appear as markers or indicators on the timeline at their specified dates.

### Editing Milestones

To modify an existing milestone:

1. Click on the milestone in the timeline or project view
2. Edit the name, date, or description as needed
3. Save your changes

### Deleting Milestones

To remove a milestone:

1. Navigate to the milestone's detail view
2. Click the delete option
3. Confirm the deletion

Milestones that no longer apply can be removed without affecting activities.

## Managing Activities on the Timeline

### Activity Timeline Display

Activities appear on the timeline once they have start and end dates assigned. Each activity displays:

- **Activity name** — The name of the work unit
- **Visual bar** — A colored bar showing the activity's scheduled duration
- **Date range** — The timeline bar spans from start to end date

### Setting Activity Dates

To define when an activity occurs:

1. Click on an activity in the list, or
2. Click **New activity** to create a new activity
3. In the activity edit form, set:
   - **Start date** — When the activity begins
   - **End date** — When the activity concludes
   - **Estimated hours** — How many hours the activity should take
4. Save the activity

The activity now appears on the timeline with a visual representation of its duration.

### Viewing Activity Details

To see details of an activity on the timeline:

1. Click the activity name in the left panel
2. Click the colored bar on the timeline
3. The activity details panel opens showing full information

### Adding Multiple Activities at Once

For complex projects with many activities:

1. Click **Add multiple activities** in the toolbar
2. A bulk entry form appears
3. Enter multiple activities with their dates and budgets
4. All activities are created and immediately appear on the timeline

This is particularly useful during initial project planning phases.

## Timeline Controls and Features

### Timeline View Levels

The timeline supports three different zoom levels for viewing your project schedule:

**Level 1 — Wide View**
- Click button **1** to show the broadest calendar view
- Best for seeing the entire project scope at once
- Shows dates compressed across a wide timespan
- Use when planning multi-month projects

**Level 2 — Standard View**
- Click button **2** for the default view
- Balances overview with detail
- Shows weekly or monthly granularity
- Recommended for most day-to-day work

**Level 3 — Detailed View**
- Click button **3** for the most detailed view
- Shows individual days clearly
- Best for week-level or sprint planning
- Use when coordinating tight schedules

### Zoom Slider

The horizontal slider at the top of the timeline allows fine-tuning the scale:

- **Drag left** — Compresses the timeline for a broader view
- **Drag right** — Expands the timeline for more detail
- The zoom level affects how many weeks or months are visible at once

### Edit, Sort, and Assign Controls

**Edit Button**
- Opens bulk edit mode for selected activities
- Edit multiple activity fields at once
- Apply changes to multiple activities simultaneously

**Sort Button**
- Changes the order of activities in the left panel
- Sort by name, date, owner, or custom criteria
- Helps organize activities for easier viewing

**Assign Button**
- Bulk assign activities to team members
- Assign multiple activities to the same person
- Set activity ownership for accountability

## Timeline Export

### Exporting Your Timeline

To save or share your project timeline:

1. Click the **Download** button in the toolbar
2. The timeline is exported in a visual format (typically PDF or image)
3. Save the exported file to your computer
4. Use the exported timeline for presentations, reports, or sharing with stakeholders

The exported timeline includes:
- All activities and their scheduled dates
- Milestones and key checkpoints
- A complete visual representation of the project schedule

## Using the Timeline for Project Management

### Planning Phase

**Initial Setup**
1. Create your project and add activities
2. Assign start and end dates to each activity
3. Define key milestones (major deliverables, approvals, client meetings)
4. Review the timeline visualization to identify conflicts or gaps

**Identifying Dependencies**
