Know more about Agile Methodology - What is Agile methodology?

What is Agile Methodology?
            
               In this model, the customer have direct communication with project team and they interact with each other to produce a software.As a result of such interaction the all ideas are exchanged the software will release in short span of time.

What is Advantage of Agile Methodology?

• The Requirement changes can be handle very easily.
• The delivery of software happens in a couple of weeks to a couple of months.
• The customer get Return On Investment(ROI) is good.
• The Business people and product development team will be having a meeting on day to day basic.
• The idle manner to have a communication with a product development team in to the face to face discussion.
• Testing is done frequently over here.
• The few rounds of testing is been carryout by the business analyst to identify to core issues with regards to the piece of software.

What is Disadvantage of Agile Methodology?

• As a document part is very less this is pretty challenging.
• When the customer is not clear in here project means it very difficult to produce product.

Using this agile methodology we have implement below methods that are:

1. SCRUM
2. Xtreme Programming(XP)

1. SCRUM

• SCRUM is an iterative,incremental methodology for project management. The SCRUM approach was originally suggest for managing product development projects.
• The delivery of software takes place with in the time standard from one to two months span of time.
• The customer wants to prioritize  what he wants 1st and what he want next.
• The customer is not ready to wait for the development team to complete the desire modules and have to collect the missing modules in the next level.
• The team is responsible for delivering the product is typically made up of 5-9 people with cross functional skills who do the actual work(analyze,design,develop,test,technical communication document etc).
• Scrum master is to protect the team and keep them focused on the task.
• Scrum focus on project management.

2. Extreme Programming(XP)

• The delivery of software takes place for 2-4 weeks span of time.
• XP to reduce the cost of changes in requirements by having multiple short development cycle.

XP workflow

They are different activities involved in XP work flow they are:

1. customer requirement
2. Test case acceptance
3. Test plan
4. code
5. Test
6. Refactor
7. Deliver

• During customer requirement the test engineer prepare a list of questions for creating a acceptance test case.In some case the customer themselves  prepare a acceptance test cases.Then next step to prepare a test plan.
• Before starting to work with code the test engineer work with the developers to prepare unit test cases.Finally they test the product to find the defect.
• Refactor is used to correcting whatever work product exists to reflect the current changes.

Agile software development

    It is a group of software development methodologies based on iterative and incremental development where requirement and solution evolve through collaboration between self-organising

and cross functional teams. They have some principles for agile methodologies that are:

• Customer satisfaction by rapid delivery like quick delivery.
• Welcome changing requirement even in late development.
• working software is delivered frequently.
• Daily co-operation between business people and developers.
• Project are built around motivated individuals who should be trusted.
• Continous attention to technical excellence and good design.
• Multiple iterations may be required to release a product.
• Business value is perceived at the beginning of the iteration.
