, Unlocking True Collaboration
The SCRUM Methodology
Each team should focus on the following five values, the Team Values:
• Focus: Break app development into smaller sprints to manage workflow effectively.
• Courage: Collaborate closely and tackle challenges together as a team.
• Openness: Regularly communicate with stakeholders and peers to foster transparency.
• Commitment: Strive for high-quality work and maintain transparency with stakeholders.
• Respect: Create an environment where team members feel safe to share and support each
other.
Agile methodology emphasizes small, cross-functional teams for rapid app development, unlike
Waterfall's large, long-term project teams. A typical Agile team:
1. Product Owner: Represents the customer and defines project requirements.
2. Lead developer/Scrum Master: Facilitates the Agile process and helps the team overcome
obstacles.
3. Developers / Team Members: Execute development tasks and deliver the product increment.
Additional roles may include:
4. Stakeholders: Provide feedback and prioritize features.
5. Subject Matter Experts (SMEs): Offer specialized knowledge for technical or domain-specific
aspects.
SMEs aren't responsible for product delivery, which falls on the core Scrum team. When scaling to
develop multiple apps, new developers may join existing teams for support and experience,
eventually forming smaller teams as they gain expertise.
Sprint 0 is a preparatory phase before the start of development in Scrum:
• Purpose: To prepare the team for development work by familiarizing them with the app,
organization, and team members.
• Activities:
• Kick-off Meeting: Formalizes agreements, clarifies responsibilities, and discusses
dependencies.
• Product Backlog Refinement Meeting: Identifies user stories for the first sprint and
ensures they are in a 'ready' state.
• Team Composition: Once team composition is clear, the Scrum Master identifies technical
challenges and books necessary Subject Matter Experts (SMEs).
• Role of Scrum Master:
• Identifies technical challenges (e.g., UX/UI, integrations, IoT, Big Data).
• Books availability of necessary SMEs, ensuring they are available for the particular
sprint where needed.
• Looks ahead several sprints and forecasts required capacity and skills.
• Outcome: Establishes transparency, clear collaboration agreements, and readiness for
development work.
The Agile process involves several events, each with specific goals and occurring in a specific order:
1. Sprint Planning:
• Preparation for the upcoming two weeks.
• Defining the Sprint goal and selecting user stories.
• Determining the Definition of Done.
• Identifying required effort and capacity.
2. Daily Stand-up:
• Daily meeting where team members share progress.
