Accepted Answer

**Scrum** is one of the most popular frameworks for implementing *Agile*. Many people think scrum and agile are the same thing but they're not.

With scrum, the product is built in a series of fixed-length iterations called sprints that give teams a framework for shipping software on a regular cadence.

Question 3

Explain what is _Refactoring_?

Accepted Answer

* To **improve the performance or readability**, the existing code is modified; this is re-factoring. 
* During re-factoring the **code functionality remains same**.

Question 4

What is _User Stories_?

Accepted Answer

**User stories** are features customers might want to see in their software. They are written on index cards to encourage face-to-face communication. Typically no more than a couple days work, they form the basis of our Agile plans.

Question 5

Three essential roles for scrum success are:
* **The Product Owner** are the champions for their product. They are focused on understanding business and market requirements, then prioritizing the work to be done by the engineering team accordingly.
* **The Scrum Master** are the champion for scrum within their team. They coach the team, the product owner, and the business on the scrum process and look for ways to fine-tune their practice of it.
* **The Scrum Team** are the champions for sustainable development practices. Scrum teams are cross-functional, "the development team" includes testers, designers, and ops engineers in addition to developers.

Question 6

Accepted Answer

* **Epic:** A customer described software feature that is itemized in the product backlog is known as epic. Epics are sub-divided into **stories**.
* **User Stories:** From the client perspective user stories define project or business functions, and delivered in a particular sprint.
* **Task:** Further down user stories are broken down into different tasks.

Question 7

Accepted Answer

In the Scrum methodology a **Sprint** is the **basic unit of development**. Scrum sprints correspond to Agile iterations.

Each Sprint starts with 
* a **planning meeting**, where the tasks for the sprint are identified and an estimated commitment for the **sprint goal** is made.

A Sprint ends with 
* a **review or retrospective meeting** where the progress is reviewed and lessons for the next sprint are identified. During each sprint, the team creates finished portions of a product.

Accepted Answer

**Test Driven Development (TDD)** is also known as test-driven design. In this method, developer:

1. first writes an **automated test** case which describes new function or improvement and 
2. then creates small codes to **pass that test**, and 
3. later **re-factors** the new code to meet the **acceptable standards**.

Question 10

Explain difference between a Product and a Sprint Backlog

Accepted Answer

* The **Product Backlog** is an ordered list of everything that is known to be needed in the product. It is the single source of requirements for any changes to be made to the product.
