Agile methodology has Customer or Client as part of theirteam. In this type the whole product or the application is divided or categorizedintovarious modules, and eachmodule isdeveloped and tested and delivered in increments hence it is also termedto be incremental model. After eachmodule is developed and testedit gains feedback from the client and only when the client is satisfied itmoves on to next module. It has different approaches extremeprogramming, SCRUM, etcalways extremeprogramming is used (Below is allabout extremeprogramming)How Agile is processed: It starts up initially with therequirements phase, in this phase all therequirements are gatheredfrom theclient.

Once the module is decided, the Development teamstartswriting thecodes and develops the particularapplication, in the project environment(Please scroll down toknow the definition) After themodule is been developed, QA teamstartstesting themodule, if they find any issues they report it to Devteamand fix theissues before releasing it to client Once testing part is successful it is implemented on real time environment and delivered to theclient. After it is been delivered to client, Client has theirexclusive QA team who does theirtesting, and let the companyknows if they haveany issues, or if they need any modifications. Once the customer is satisfied with that particularmodule that particularmodule is signed-off(Client is satisfiedhence closing that module work) and we will move on to next module. If client is not satisfied we will work on same module until he says OK.Features:o Eachmodule separateuser story, the requirements in Agileis termedto User story.o Eachmodule is considered to be separateproject.o Developer and tester work in pairs for e.g. one developer writescodes and other verifies it, in similar wayonetester writes test case and other reviews it and execute it.When do we use Agile: When the customer does not have a clear understanding of the details of the new system. The developersinteract continuously with the customer, delivering small pieces of the application to the customer forfeedback, and taking corrective action as necessary. When the technology used to develop the system is new compared to other technologies. Frequent testcycles in Extreme Programming mitigate the risk of incompatibility with other existing systems. When you can afford to create automated unit and functional tests. In some situations, you may need tochange the system design so that each module can be tested in isolation using automated unit tests. When the team size is not very large (usually 2 to 12 people). Extreme Programming is successful in partbecause it requires close team interaction and working in pairs. A large team would have difficulty incommunicating efficiently at a fast pace. However, large teams have used Extreme Programmingsuccessfully.User Story:A user story is a short, simple description of a featuretold from theperspective of the person who desires the newcapability, usually a user or customer of the system.For Example: User story for login describesA user needs tologin to pay their bills online so that it makes easy mode of payment. Login appears in the right corner of the page. Login page looks something like this.

It is giving thisprojectto H2k Infosys Company.The requirements of this project are as follows:1. Customer should login with valid username and password.2. After logging in he has links called account summary, funds transfer, receivefunds, pay credit cardbills, etc3. He cantransfer $ 10000 per day.4. He canreceive $5000 per day.User story for Login:1. User Name: It should be alpha numeric containing one alphabet and numbers2. Password : It should be case sensitive It should contain one higher case, one special character, oneor more lower case, one more number. It should be minimum of 6 values and max of 10Module:After categorizing, since each performs different functionality each will be considered as modules. In this ABCBank the modules will be Login View summary Transfer Pay Bills Receive In this first login login is createdand testedin project environment i.e dummy environment and after testing isdone and making sure login is working fine, meeting all the requirements, all the scenarios mentioned in User storypasses, then it is implemented on realtime environment. After this process H2k will deliver this particularmodule to ABC Bankand gains feedback and make it sure whetherthey aresatisfied. Once the customer is satisfied the LOGINmodule is finalized and move on next module accounts summary.What is Dummy / QA TEST environment or / TEST BED/ project environmentand what is Real time environment?
