↩Back to Iterative Development Cycle

The Agile process starts with the manifesto values, follows the 12 principles, and cycles through iterative development, frequent delivery, and adaptation based on feedback.

Execution Sample

Software Engineering

1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan

These four lines represent the core values of the Agile Manifesto guiding software development.

Analysis Table

Step	Action	Description	Result
1	Start project	Project team begins work	Ready to apply Agile values
2	Apply Agile Manifesto values	Focus on people, working software, collaboration, and flexibility	Guides team mindset
3	Follow Agile principles	Use 12 principles like frequent delivery, welcoming change	Sets detailed behavior rules
4	Develop iteratively	Work in short cycles called iterations or sprints	Produces small working software parts
5	Deliver working software frequently	Release usable software every few weeks	Stakeholders see progress
6	Gather feedback	Collect input from users and team	Identify improvements
7	Adapt plan	Change priorities and work based on feedback	Keeps project aligned with needs
8	Repeat iterative cycle	Go back to development with updated plan	Continuous improvement
9	End project	When goals met or product complete	Project delivered successfully

💡 Project ends when goals are met or product is complete

Key Insights - 3 Insights

Why does Agile emphasize 'working software over comprehensive documentation'?

Because delivering usable software frequently (see execution_table step 5) helps teams and customers see real progress, rather than spending too much time on documents that may become outdated.

How does Agile handle changes in project requirements?

Agile welcomes change even late in development (step 7), adapting plans based on feedback to keep the project aligned with customer needs.

What is the purpose of iterative development cycles in Agile?

Iterative cycles (step 4 and 8) break work into small parts, allowing frequent delivery and continuous improvement through feedback.

Visual Quiz - 3 Questions

Look at the execution_table, at which step does the team first deliver working software?

A Step 4

B Step 5

C Step 6

D Step 7

💡 Hint

Check the 'Result' column for 'Stakeholders see progress' in the execution_table

According to variable_tracker, what is the team mindset after step 3?

A Undefined

B Focused on Agile values

C Aligned with Agile principles

D Ready for iterative work

💡 Hint

Look at the 'Team mindset' row under 'After Step 3' in variable_tracker

If the team skips gathering feedback (step 6), what impact would it have on the Agile cycle?

A Plan adaptation would be less effective or missing

B No impact, cycle continues as normal

C Working software delivery would stop

D Project would end immediately

💡 Hint

Refer to execution_table steps 6 and 7 where feedback leads to plan adaptation

Concept Snapshot

Agile Manifesto has 4 key values:
- People over processes
- Working software over docs
- Customer collaboration over contracts
- Responding to change over plans
Follow 12 principles like frequent delivery and welcoming change.
Work in short cycles, deliver often, get feedback, adapt continuously.

Full Transcript

The Agile Manifesto guides software projects by valuing individuals and interactions, working software, customer collaboration, and flexibility over rigid processes and plans. Teams follow 12 principles that emphasize frequent delivery, welcoming change, and continuous improvement. The process flows from applying these values and principles to working in short iterative cycles called sprints. After each cycle, teams deliver working software, gather feedback, and adapt plans accordingly. This cycle repeats until the project goals are met. Key moments include understanding why working software is prioritized over documentation, how Agile embraces change, and the role of iterative development. Visual tables track the team's mindset and project progress step-by-step, showing how Agile keeps projects flexible and focused on real results.
