  2. Scrum Master: responsible for facilitating the Scrum process, and ensuring that the team is following the Scrum framework.

  3. Development Team: responsible for developing the software, and delivering working increments of the product.

The Scrum process consists of the following steps:

  1. Sprint Planning: the team plans the work to be done during the upcoming sprint (a short iteration, typically 2-4 weeks).

  2. Daily Scrum: the team holds a daily meeting to discuss progress, and plan the work for the day.

  3. Sprint Review: the team reviews the work completed during the sprint, and receives feedback from stakeholders.

  4. Sprint Retrospective: the team reflects on the sprint, and identifies opportunities for improvement.

Kanban Methodology

Kanban is a visual system for managing work, developed by Taiichi Ohno and Shigeo Shingo in the 1950s. Kanban emphasizes continuous flow, and limits work in progress (WIP) to maximize efficiency. Kanban is not a framework, but rather a set of principles and practices that can be applied to software development teams.

The core principles of Kanban are:

  1. Visualize the workflow: use a board or chart to visualize the workflow, and track progress.

  2. Limit WIP: limit the amount of work in progress to prevent overloading the team.

  3. Flow: focus on continuous flow, and delivering working software.

  4. Pull: pull work into the system, rather than pushing work onto the team.

  5. Continuous improvement: continuously improve the process, and eliminate waste.
