Study Notes
Exploring Agile Development
- Team Assembly: Building a team requires assessing skills and exploring potential technologies.
- Playful Curiosity: Maintaining a playful and curious approach towards work environment, problems, technologies, and people is essential.
- Agile Planning Game:
- Maximizes the system's value.
- Simplicity is prioritized.
- Early production and customer feedback drive design.
- Story Cards are used to describe tasks, provide tracking, and facilitate communication.
- Players: Development Team and Business Customer are key players.
Iterations and Production
- Iterations: Cycles of testing, feedback, and change.
- Customer-Written Function Tests: Performed at the end of each iteration.
- Productionizing:
- Feedback cycles accelerate.
- Daily briefings are crucial.
- Product is released and may be improved with additional features.
Maintenance
- Regular Updates: New features can be added, riskier customer suggestions can be considered.
- Team Rotation: Team members can be rotated.
Importance of System Design
- Proper Planning: System installation without proper planning leads to user dissatisfaction and potential disuse.

- Method Specifications: Detailing method input, output, and processing.
Developing and Documenting the System
- Documentation Importance: Complete documentation helps with faster development and a more robust final product.
- Iteration Approach: Object-oriented methodologies often focus on small, quick iterations.
Choosing the Right Development Method
- Understanding the Organization: Thorough understanding of the organization's structure, culture, and needs.
- Budgeting Time and Resources: Developing a project proposal with allocated time and resources.
- Data Gathering: Conduct detailed data collection through interviews and questionnaires.
- Observing Business Processes: Direct observation of current business practices.
Method Similarities
- SDLC and OOAD: Require extensive planning and diagramming.
- Agile and OOAD: Allow for building subsystems one at a time.
- Agile and SDLC: Focus on data flow within the system.
Method Selection Criteria
- Systems Development Life Cycle (SDLC):
- Applicable when systems have a documented history using SDLC.
- Provides a clear understanding of each step in the development process.
- Appropriate for organizations that prefer a structured approach.
- Agile Methodologies:
- Ideal for organizations with a champion for agile methods.
- Enables rapid development in dynamic environments.
- Useful for rescue projects where time is of the essence.
- Object-Oriented Methodologies:
- Suitable when problems can be effectively modeled as classes.
- Supports organizations that are familiar with UML.
