↩Back to Change in Requirements?

Agile starts with initial planning, develops features in short cycles, reviews feedback, and adapts plans if requirements change, repeating this loop.

Execution Sample

Software Engineering

Sprint 1: Plan -> Develop -> Review
If feedback requires change:
  Update backlog
  Plan Sprint 2
  Develop new features
Repeat

This shows how Agile works in cycles, adapting to changes after each review.

Analysis Table

Step	Action	Feedback/Condition	Decision	Next Step
1	Gather initial requirements	Requirements collected	Proceed to planning	Plan Sprint
2	Plan Sprint	Sprint backlog created	Start development	Develop features
3	Develop features	Features built	Ready for review	Review & feedback
4	Review & feedback	Change requested?	Yes	Update backlog & plan
5	Update backlog & plan	Backlog updated	Plan next sprint	Plan Sprint
6	Plan Sprint	New sprint backlog	Start development	Develop features
7	Develop features	New features built	Ready for review	Review & feedback
8	Review & feedback	Change requested?	No	Continue next sprint
9	Continue next sprint	Project progresses	Repeat cycle	Develop features or finish

💡 When no changes are requested during review, Agile continues with the current plan until project completion.

State Tracker

Variable	Start	After Step 4	After Step 5	After Step 8	Final
Requirements	Initial set	Change requested	Backlog updated	No change	Finalized
Sprint backlog	Created	Needs update	Updated with changes	Stable	Used for development
Features developed	None	Partial	Updated features	Complete	Delivered

Key Insights - 3 Insights

Why does Agile plan in short cycles instead of all at once?

Because Agile expects requirements to change, short cycles let teams adapt quickly after each review (see execution_table steps 3-5).

What happens if no changes are requested during review?

The team continues with the current plan and moves forward to the next sprint or project completion (see execution_table step 8).

How does Agile handle new or changed requirements?

It updates the backlog and replans the next sprint to include changes, allowing flexible response (see execution_table steps 4-6).

Visual Quiz - 3 Questions

Look at the execution_table at step 4: What decision is made if change is requested?

A Stop the project

B Continue with current sprint

C Update backlog and plan next sprint

D Ignore the feedback

💡 Hint

Refer to the 'Decision' column in row for step 4 in execution_table.

According to variable_tracker, what happens to 'Sprint backlog' after step 5?

A It is discarded

B It is updated with changes

C It remains the same

D It is finalized

💡 Hint

Check the 'Sprint backlog' row and the 'After Step 5' column in variable_tracker.

At which step does Agile decide to continue without changes?

A Step 8

B Step 3

C Step 6

D Step 9

💡 Hint

Look at the 'Feedback/Condition' and 'Decision' columns for step 8 in execution_table.

Concept Snapshot

Agile works in short cycles called sprints.
Each sprint plans, develops, and reviews features.
Feedback after each sprint may change requirements.
Backlog updates allow flexible response.
If no changes, Agile continues smoothly.
This keeps projects adaptable and efficient.

Full Transcript

Agile methodology responds to changing requirements by working in short cycles called sprints. The process starts with gathering initial requirements and planning a sprint. The team develops features during the sprint and then reviews the work with stakeholders. If feedback requests changes, the backlog is updated and the next sprint is planned accordingly. This cycle repeats, allowing the team to adapt quickly to new or changing needs. If no changes are requested during review, the team continues with the current plan. This approach keeps projects flexible and responsive to change, avoiding rigid long-term plans that may become outdated.
