what is the recommended hierarchy in agile scrum : Epic, Feature, User story, task ( real-world example )
(how to estimate these different levels using Story Points or hours?)  |Link|

In Agile and Scrum, the recommended hierarchy for structuring work moves from broad strategic goals down to specific technical actions.

The Standard Work Hierarchy

1. Epic: The highest level of work, representing a large, strategic initiative or a major body of work that cannot be completed in a single sprint. Epics often span multiple months or several releases.

2. Feature: A distinct piece of functionality or capability that delivers measurable value to the user. Features act as the bridge between broad epics and granular stories, typically sized to be completed within a few sprints.

3. User Story: The smallest unit of value that can be delivered to a customer within a single sprint. These are written from the end-user's perspective (e.g., "As a user, I want [goal] so that [benefit]").

4. Task: The technical or operational steps required to complete a user story. These are usually small enough to be finished in a single day by a specific team member.

Comparison Table

Many organizations also add Themes (or Initiatives) above Epics to group them under long-term organizational goals. In frameworks like the Scaled Agile Framework (SAFe), the inclusion of the "Feature" level is critical for coordinating large-scale releases.

Would you like to see a real-world example of how a specific project (like building a mobile app) would be broken down across these four levels?

In Agile, estimation typically uses story points for high-level planning and hours for low-level execution. The general rule is: the higher you are in the hierarchy, the more abstract and relative the estimate becomes.

The Estimation Hierarchy

1. Story Points (The "What" and "How Hard")

Story points are a relative measure of effort, complexity, and risk. Teams usually use the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21) because it highlights the increasing uncertainty as tasks get larger.

• Why use points? They don't change based on who does the work. A 5-point story is 5 points whether a senior or junior developer tackles it, even if they take different amounts of time to finish.

• Forecasting: By tracking how many points the team completes per sprint (Velocity), you can predict when future features will be finished.

2. Hours (The "When")

Hours are absolute units used for the most granular level: Tasks.

• Why use hours? During Sprint Planning, the team breaks User Stories into Tasks. Estimating these in hours (e.g., 2h for "CSS styling", 4h for "API integration") helps the team ensure they aren't overcommitting for the specific two-week window.

• Tracking: Hours help in daily standups to see if a specific task is "stuck" or taking longer than expected.

3. The "Hybrid" Approach

Many mature teams use a hybrid model:

1. Estimate User Stories in points to maintain a long-term roadmap.

2. Break those stories into Tasks estimated in hours for immediate tactical execution.

Important: Avoid the "Conversion Trap." Never say "1 story point = 8 hours." This destroys the benefit of story points because it ignores complexity and forces a rigid timeline that often leads to burnout.

These guides offer insights into Agile estimation techniques, differentiating between story points and hours and cautioning against direct conversion.

openproject how to use versions to keep track of sprints and releases   |Link|

1. Create and Configure Versions

Versions are managed within project settings.

1. Navigate to your project.

2. Go to Project settings -> Versions in the left menu.

3. Click the green + Version button.

4. Configure Details:

   • Name: Define the Sprint (e.g., "Sprint 1") or Release (e.g., "v1.0").

   • Start/Finish Date: Set the planned timeline.

   • Sharing: Determine if this version is used only in this project or shared with subprojects.

2. Managing Sprints

Sprints are typically listed in the left-hand column of the Backlogs view and represent chronological iterations.

• Create Sprint Version: Create a version and name it (e.g., "Sprint 1").

• Set as Backlog: In the version settings, ensure it is configured to show in the backlogs view.

• Backlogs View: Navigate to the Backlogs module. Drag and drop work packages (user stories/tasks) into the sprint version container.

• Task Board: Once a sprint has work packages, you can open the Task Board to visualize task progress (e.g., New, In Progress, Done).

• Burndown Chart: OpenProject automatically generates a burndown chart for the sprint based on story points or estimated hours to track progress.

• Sprint Wiki: Create a dedicated Wiki page per sprint to document planning and retrospectives.

3. Managing Releases

Releases usually refer to functional milestones or product versions, visible in the Roadmap module.

• Create Release Version: Create a version for a release (e.g., "Release 2.0").

• Roadmap View: Go to the Roadmap module to see a progress bar for the release, calculated based on the percentage of completed work packages assigned to it.

• Linking to Wiki: Link a Wiki page to the version to create a "Release Notes" page that is directly accessible from the Roadmap.

4. Version Workflow (Open, Locked, Closed)

Use version statuses to control the workflow:

• Open: Work packages can be added/removed, and it is visible in Backlogs and Roadmap.

• Locked: Work packages cannot be added or removed. Use this when a sprint or release scope is frozen.

• Closed: The sprint/release is complete. It is hidden from active backlogs and roadmaps, preserving the history.

5. Tracking with Boards

• Version Board: Create an Agile Board, selecting "Version" as the type. This creates a column for each version (release/sprint), allowing you to move tasks between them.

Key Tips for Success

• Hierarchy: Sprints can be nested within a larger Release version (e.g., Sprint 1, 2, 3 all belong to Release v1.0).

• Automatic Assignment: When working in the backlogs view, dragging a task onto a sprint automatically updates the target version of that task.

• Sprint vs. Release: Sprints are best for Scrum teams (Backlogs module), while Releases are best for project timelines (Roadmap module).
