describe the responsibility of the Scrum team for turning PBIs in the sprint backlog into increments of value.

As a cohesive unit, they carry the responsibility of turning Product Backlog Items (PBIs) into valuable deliverables known as Increments. The PBIs, which constitute the Sprint Backlog, contain the functionality that needs to be developed during the Sprint.

Let’s start by breaking down the roles in the Scrum Team:

Product Owner (PO): The PO is responsible for the Product Backlog, including its content, availability, and ordering. It’s the PO’s job to ensure the team is working on the highest value PBIs at any given time.

Development Team: This group is composed of professionals who do the work of delivering a potentially releasable Increment of “Done” product at the end of each Sprint.

Scrum Master: They are servants-leaders and facilitate Scrum as described in the Scrum Guide, helping everyone understand Scrum theory, practices, rules, and values.

Once the roles we discussed are well defined, the PBIs are refined and turned into Increments of value via a process called a Sprint. Let’s delve more into how that happens.

Sprint Planning:

In the Sprint Planning, the Scrum team collaboratively decides what to develop in the upcoming Sprint from the Product Backlog. The selected set becomes the Sprint Backlog. The Product Owner discusses the objective that Sprint should achieve and the PBIs that, if completed in the Sprint, result in the desired outcome. The entire Scrum Team collaboratively decides on the functionality and technology for delivering the desired outcome.

Daily Scrum:

In the Daily Scrum, the Development Team inspects the progress towards the Sprint Goal and checks whether the Sprint Backlog is on track. They discuss their individual progress on the PBIs and adjust their plan to meet the Sprint Goal.

Development:

Throughout the Sprint, the Development Team develops the required functionality and technology to turn the Sprint Backlog into a done Increment. They adhere to agreed-upon Definitions of Done to ensure the quality of the Increment.

Sprint Review:

At the end of the Sprint, the Scrum Team and stakeholders attend the Sprint Review where the Development Team demonstrates the functionality they created during the Sprint. Based on this and the current Product Backlog, they collaborate and adjust the overall direction of the project.

Sprint Retrospective:

Finally, the Scrum Team participates in the Sprint Retrospective where they inspect the last Sprint and identify and plan ways to improve their process in the upcoming Sprint. The Scrum Master ensures that the team devotes enough time and focus to this continuous improvement practice.

To illustrate a clear picture, let’s suppose a team is developing a custom eCommerce application. During Sprint Planning, the PO decides a PBI such as “User can view the product detail page” as the value for that Sprint. The Development Team collaboratively decides the tactic to transform the PBI into an Increment. They utilize daily Scrum meetings to inspect their progress, adapt their strategy if needed, and collaborate on tasks. By the end of the Sprint, they deliver a functional product detail page. Their work is demonstrated to stakeholders in the Sprint Review and then strategies for improvement for the next Sprint are discussed in the Sprint Retrospective.

In conclusion, the responsibility to turn PBIs into a valuable Increment in each Sprint lies with the collaborative efforts of the whole Scrum Team. Each member plays a crucial part; the Product Owner decides what value to deliver, the Development Team builds that value, and the Scrum Master facilitates the process efficiently.
