Study Notes
Agile Project Management
- Software project managers aim to deliver projects on time and within budget.
- Traditional project management follows a plan-driven approach, detailing deliverables and timelines.
- Agile project management adapts to incremental development with different practices.
Scrum
- Scrum is an agile method that manages iterative development.
- Three main phases: outline planning, sprint cycles, and project closure.
- Sprint cycles focus on developing system increments and finalizing project documentation.
Scrum Terminology
- Development team: A self-organizing group of up to 7 developers responsible for software and documentation.
- Potentially shippable product increment: A software version delivered at the end of a sprint, ideally ready for deployment.
Scrum Sprint Cycle
- Sprints last 2-4 weeks, starting with a product backlog for work organization.
- Team collaborates with customers to select features for each sprint.
- Team isolates from customers during sprints, communicating through a Scrum Master.
Teamwork in Scrum
- The Scrum Master facilitates daily stand-up meetings, tracks progress, and manages communications.
- Daily scrums provide updates on progress, obstacles, and plans for the next day.
Benefits of Scrum
- Projects are divided into manageable increments for better clarity.
- Unstable requirements do not hinder progress.
- Improved team communication and visibility promotes collaboration.
Contractual Issues
- Custom software contracts typically based on detailed specifications, limiting agile development practices.
- Agile requires contracts paying for developer time over predefined functionalities, posing risks for legal departments.
Agile Methods and Software Maintenance
- Organizations spend more on maintaining existing software than on new development.
- Key issues: maintainability of agile systems due to minimal documentation and evolving systems in response to customer demands.
Agile Maintenance Challenges
- Key problems include lack of documentation, customer involvement, and consistent development team continuity.
- Long-lifetime systems face issues when original developers are no longer involved.
Agile and Plan-Driven Methods
- Many projects use a mix of agile and plan-driven methods for flexibility.
- Detailed specifications are essential for complex projects; agile methods suited for smaller, co-located teams.
Agile Principles and Organizational Practice
- Customer involvement requires committed customer representation, which is challenging with stakeholder diversity.
- Embracing change while aligning with long-term business planning poses difficulties.
- Simplicity in development can be sacrificed under delivery pressure.
Large System Development
- External regulations often constrain development processes for large systems.
- Maintaining cohesive teams over long project durations is difficult due to staff turnover.
- Diverse stakeholders complicate the development process by making comprehensive involvement unfeasible.
IBM’s Agility at Scale Model
- Requires structured cross-team communication and coordinated efforts across multiple teams for successful agile practices in large projects.
Multi-Team Scrum
- Each sub-team has its own Product Owner and Scrum Master to manage components effectively within the larger project structure.
