App development process

The application (software) development cycle describes phases of the application cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the cycle. Overall the application development process is complex and requires multiple different tools and interactions with many different stakeholders. 
There are following six phases in the typical application development process:
1.Planning - This is the first phase of the application development life cycle. At this stage, you determine the basic requirements requested, make a feasibility work for the project and execute the project plan. It is the stage where the work is projected, the idea is revealed, and the idea is discussed.
2.Analysis - Business requirements are gathered in this phase. After requirement gathering, these requirements are analyzed for their validity, and the possibility of incorporating the requirements in the app to be developed is also studied.
3.Design - In this phase, the system and application design are prepared from the requirement specifications studied in the previous phase. 
4.Implementation - As the design phase of the implementation reaches a certain maturity, the development (coding) phase begins. This stage is the process in which the product to be delivered to the customer is developed.
5.Testing & integration - After the code is developed, it is tested against the requirements to ensure that the product is actually solving the needs addressed and gathered during the requirements phase. On the other hand, integration is the configurations and tests performed to enable the developed application to interact correctly with other products in the environment.
6.Maintenance - After successful testing, the product is delivered/deployed to the customer for their use. There are different activities in the maintenance phase, such as adding new features to the product, resolving errors, bugs and defects, and monitoring the application's performance. Based on the feedback from the users, new improvements can be made, and existing problems can be solved in the application.
Considering the need for agility and faster time to market for new products and services, the automation of the application development process becomes more and more important. Therefore, organizations need to improve collaboration between business and IT, design and develop applications using the principles from a component-based architecture to create autonomous and independent systems, and automate testing, infrastructure provisioning, and deployment processes to keep up for the continuing change.
