SAFe-POPM PI Execution

PI Execution Detailed Explanation

Content of PI Execution

1. Managing Incremental Development

   • What is Incremental Development? Incremental development refers to breaking down the overall work into smaller, manageable features (increments) and delivering them step by step. During the Program Increment (PI), the goal is to deliver these features continuously, providing value at each step.

   • Role of the Product Owner (PO) and Product Manager (PM): The PO and PM work closely to ensure that the teams are developing and delivering these increments according to the plan set during PI Planning. They must be prepared to make adjustments as new information or changing priorities emerge. For example, if a new business requirement comes up mid-PI, the PO may need to re-prioritize tasks to accommodate this change.

   • Example: Suppose the PI goal is to launch a new user registration process for a mobile app. The development would be broken down into increments such as creating the user interface, connecting it to the backend, and implementing email verification. Each part is delivered in increments during the PI, so progress is visible and measurable.

2. Tracking Progress and Adjustments

   • How does progress tracking work? Throughout the PI, the PO is responsible for monitoring the progress of each iteration. This ensures that all teams stay aligned with the larger objectives set during PI Planning. The PO regularly checks if the teams are on track and makes adjustments if necessary.

     If a team falls behind, the PO may decide to reduce the scope of their work for the iteration or shift lower-priority tasks to future iterations. For example, if one team is struggling to meet a deadline due to technical challenges, the PO might adjust priorities to focus on the most critical features.

   • Adjusting Priorities: The PO must always be ready to adjust priorities or modify the scope to ensure that the most valuable features are delivered. This might involve moving some tasks to the next PI or breaking large tasks into smaller, more achievable parts.

3. Delivering and Evaluating Value

   • What happens toward the end of the PI? As the PI approaches its conclusion, the PO and PM evaluate the work completed by the teams. The main question here is: Did the delivered features meet the business objectives? If yes, the PO and PM ensure the work aligns with the business goals set at the beginning of the PI.

   • System Demo: A key event during PI execution is the System Demo. In this demo, the teams showcase their completed work to stakeholders, such as business owners, product managers, and customers. The demo allows stakeholders to provide feedback and confirm that the features delivered meet their expectations. For instance, the user registration process for the mobile app might be shown to internal stakeholders to ensure that it meets user needs and technical standards.

4. Continuous Improvement

   • What happens after PI execution? After completing the PI, the PO and PM hold a retrospective to review the overall performance. This is an opportunity to reflect on what worked well and what didn’t. The retrospective helps the team identify areas for improvement so that future PIs can be executed more smoothly and efficiently.

     Key Questions in a Retrospective:

     • Were the business goals met?
     • What obstacles did the teams face?
     • What can be improved in the next PI?

   • Example: If the team faced delays due to communication issues between different departments, this could be addressed in the retrospective. The PO and PM could suggest improving cross-team communication for the next PI to avoid similar problems.

Summary

Program Increment (PI) execution involves managing the continuous delivery of features throughout the PI cycle. The Product Owner (PO) and Product Manager (PM) ensure that all development activities are on track, making necessary adjustments based on progress and priority changes. Toward the end of the PI, the PO and PM evaluate the delivered features to ensure they meet business goals, and retrospectives help improve future PI performance by identifying areas for improvement.

PI Execution (Additional Content)

Program Increment (PI) Execution is the phase where Agile teams develop, integrate, and deliver value within a Program Increment (PI), typically lasting 8-12 weeks. Effective PI Execution ensures that teams align with business goals, track progress, manage dependencies, and continuously improve.

1. Key Roles in PI Execution

While the Product Owner (PO) and Product Manager (PM) drive backlog prioritization and execution, several additional roles are essential for effective PI Execution.

1.1 Release Train Engineer (RTE)

• Ensures the Agile Release Train (ART) stays on track to meet PI Objectives.
• Facilitates ART-wide coordination to resolve impediments.
• Organizes ART Sync meetings to manage dependencies.
• Maintains visibility into progress and risks.

1.2 System Architect

• Provides technical guidance and ensures solutions align with enterprise architecture.
• Identifies and resolves technical dependencies between teams.
• Ensures code quality and technical feasibility across Agile teams.

1.3 Business Owners

• Evaluate whether delivered value aligns with business goals.
• Participate in System Demos to provide feedback.
• Assess Business Value Achievement at the end of the PI.

Why Are These Roles Important?

• The RTE ensures execution consistency across teams.
• The System Architect ensures technical soundness.
• The Business Owners validate business value delivery.

2. ART Sync Mechanism

ART Sync ensures that teams stay aligned throughout the PI Execution phase. It consists of:

2.1 Scrum of Scrums

• Facilitated by the RTE.
• Scrum Masters from each team discuss progress, dependencies, and risks.
• Bottlenecks are identified and escalated for resolution.

2.2 PO Sync

• Facilitated by the Product Manager (PM).
• Product Owners align priorities across teams.
• Ensures that iteration execution remains aligned with PI goals.

Why Is ART Sync Important?

• Scrum of Scrums resolves team-level dependencies.
• PO Sync ensures cross-team backlog prioritization.

3. System Demo

The System Demo is a critical event in SAFe's PI Execution process, providing stakeholders with visibility into the work completed across all teams.

3.1 Goals of System Demo

• Validate that delivered work provides business value.
• Gather feedback from Business Owners and stakeholders.
