Individuals and Interactions OVER Processes and Tools
Working Software OVER Comprehensive Documentation
Customer Collaboration OVER Contract Negotiation

What is rapid software development?
most important requirement for software systems nowadays. Software has to evolve quickly.
What are the 12 principles of agile methods?
- Satisfy the customer
- Welcome change
- Deliver working software frequently
- Work Together
- Trust and Support
- Face-to-face communication is best
- Working software
- Promote sustainable development

- Maintain simplicity
- Self-organizing teams

Should user plan-driven approach
plan-driven or agile: Is an incremental delivery strategy, where you deliver the software to customers and get rapid feedback from them, realistic?

plan-driven or agile: What type of system is being developed?
Plan-driven is possibly a must for systems that need a ton of analysis before implementation
plan-driven or agile: What technologies are available to support system development?
Agile methods rely on good tools to keep track of an evolving design
plan-driven or agile: how good are the programming skills of the developers?
Agile methods need higher skill levels when compared to plan-driven
What are the main characteristics of agile development?
- keep things small
- deliver partially-completed software frequently
- talk to the customer often

- everyone on the team learns together
What are some agile practices?
- short timeboxed iterations
- continuous integration
- daily unit testing
- regular retrospectives
- direct communication between devs and the cx
- a single list of features and tasks
- short-term estimation of dev tasks
- information radiators
- refactoring
There is ___ to do requirements in agile development
no standard way
Why is agile development important?
- large feature sets could increase the cost for the customer
- constant introduction of new technologies
- new players enter the market
- “small is beautiful”
- if we listen to customer, we reduce our chances of being blindside by smaller, more flexible competitors
- anything that helps reduce maintenance costs is awesome
