Application Lifecycle Management in SharePoint 2010

The exact way to develop design ,test and deploy the SOM application in share point.The article is taken from MSDN and may be helpful for sharepoint guys.

The following are the specific steps in the process illustrated in Figure 1 (see corresponding callouts 1 through 10):

1. Someone (for example, a project manager or lead developer) collects initial requirements and turns them into tasks.
2. Developers use Microsoft Visual Studio Team Foundation Server 2010 or other tools to track the development progress and store custom source code.
3. Because source code is stored in a centralized location, you can create automated builds for integration and unit testing purposes. You can also automate testing activities to increase the overall quality of the customizations.
4. After custom solutions have successfully gone through acceptance testing, your development team can continue to the pre-production or quality assurance environment.
5. The pre-production environment should resemble the production environment as much as possible. This often means that the pre-production environment has the same patch level and configurations as the production environment. The purpose of this environment is to ensure that your custom solutions will work in production.
6. Occasionally, copy the production database to the pre-production environment, so that you can imitate the upgrade actions that will be performed in the production environment.
7. After the customizations are verified in the pre-production environment, they are deployed either directly to production or to a production staging environment and then to production.
8. After the customizations are deployed to production, they run against the production database.
9. End users work in the production environment, and give feedback and ideas concerning the different functionalities. Issues and bugs are reported and tracked through established reporting and tracking processes.
10. Feedback, bugs, and other issues in the production environment are turned into requirements, which are prioritized and turned into developer tasks. Figure 2 shows how multiple developer teams can work with and process bug reports and change requests that are received from end users of the production environment. The model in Figure 2 also shows how development teams might coordinate their solution packages. For example, the framework team and the functionality development team might follow separate versioning models that must be coordinated as they track bugs and changes.
