Agile Methodology for mobile application development

 

AGILE methodology is a methodology which provide continuous iteration of development and testing  the software development lifecycle of the project. Development and testing of the software activities are opposite of waterfall model. There are various agile development methods  like scrum,crystal methodologies,dynamic software development method,feature driven development ,lean software development and extreme programming.

Scrum

Scrum is an agile development method which  focus  on how to manage tasks within a team . Scrum is use for empowering team and working in small team for improve software.
It consists of three roles, and their responsibilities are explained as follows:

  • Scrum Master
    • Master is responsible for setting up the team, sprint meeting and removes obstacles to progress
  • Product owner
    • The Product Owner creates product backlog, prioritizes the backlog and is responsible for the delivery of the functionality at each iteration
  • Scrum Team
    • Team manages its own work and organizes the work to complete the sprint or cycle

Product Backlog

This is a repository where requirements are tracked with details . It should be maintained and prioritized by Product Owner, and it should be distributed to the scrum team. Team can also request for a new requirement addition or modification or deletion

Process flow of Scrum Methodologies:

Process flow of scrum testing is as follows:

  • Each iteration of a scrum is known as Sprint
  • Product backlog is a list where all details are entered to get end product
  • During each Sprint, top items of Product backlog are selected and turned into Sprint backlog
  • Team works on the defined sprint backlog
  • Team checks for the daily work
  • At the end of the sprint, team delivers product functionality

Most of the company follow Agile methodology for mobile application development . We can provide early and ongoing delivery of the software and app modules to our valuable clients with the help of agile methodology. We have found that mobile application development  process becomes more quick, easy and efficient using agile technology. Agile technology provides lightweight development process and value to build applications in short cycles with quality check in every step.

Benefits of agile methodology :

  • Visibility
  • Cost Control
  • Simple design
  • Personalization
  • Ability to adapt to changes
  • Focuses on Business Value
  • Predictable Costs and Schedule
  • Even late changes in requirements are allowed

Waterfall Model

Waterfall development is  not allow much reflection or revision. Once an application is in the testing stage, it is very difficult to go back and change something that was not well-documented or thought upon in the concept stage.

      The major disadvantages of the Waterfall Model are as follows
  • No working software is produced until late during the life cycle.
  • High amounts of risk and uncertainty.
  • Not a good model for complex and object-oriented projects.
  • Poor model for long and ongoing projects.
  • Not suitable for the projects where requirements are at a moderate to high risk of changing. So, risk and uncertainty is high with this process model.
  • It is difficult to measure progress within stages.
  • Cannot accommodate changing requirements.
  • Adjusting scope during the life cycle can end a project.

Agile Methology

       The major disadvantages of the Waterfall Model are as follows
  • Rapid, continuous delivery of useful software is satisfied the customers.
  • People and interactions are emphasized rather than process and tools. Customers, developers and testers constantly interact with each other.
  • Working software is delivered frequently (weeks rather than months).
  • Face-to-face conversation is the best form of communication.
  • Close, daily cooperation between business people and developers.
  • Continuous attention to technical excellence and good design.
  • Regular adaptation to changing circumstances.
  • Even late changes in requirements are welcomed.

Step1 :  First Team will analysis requirement.
Step 2 : Designers will Design Application.
Step 3 : Developers will Build Application.
Step4 :  QA team will ensures excellent Quality for the application.
Step5 : We will take the feedback from our client if modifications or issues are there then
process will be continue
Step6 : If there is no any issues then successful Mobile Application will be delivered to the client.

Conclusion:

If you want to be agile, the first tenet is “Every project needs a slightly different set of
policies and      conventions, or    methodology.” People’s attitude toward communication, user
involvement, and frequent releases is more important than the specific process you use.
