The process is defined as a sequence of steps. When followed, it helps to achieve a goal. We consider it - the art of thinking through.


Before we even begin with the planning stage, the best tip we can give you is to take time and acquire proper understanding of app development life cycle. The planning stage (also called the feasibility stage) is exactly what it sounds like: the phase in which developers will plan for the upcoming project. It helps to define the problem and scope of any existing systems, as well as determine the objectives for their new systems. By developing an effective outline for the upcoming development cycle, they'll theoretically catch problems before they affect development. And help to secure the funding and resources they need to make their plan happen. Perhaps most importantly, the planning stage sets the project schedule, which can be of key importance if development is for a commercial product that must be sent to market by a certain time.


The analysis stage includes gathering all the specific details required for a new system as well as determining the first ideas for prototypes. Developers may: Define any prototype system requirements Evaluate alternatives to existing prototypes Perform research and analysis to determine the needs of end-users Furthermore, developers will often create a software requirement specification or SRS document. This includes all the specifications for software, hardware, and network requirements for the system they plan to build. This will prevent them from overdrawing funding or resources when working at the same place as other development teams.


The development stage is the part where developers actually write code and build the application according to the earlier design documents and outlined specifications. This is where Static Application Security Testing or SAST tools come into play. Product program code is built per the design document specifications. In theory, all of the prior planning and outlined should make the actual development phase relatively straightforward. Developers will follow any coding guidelines as defined by the organization and utilize different tools such as compilers, debuggers, and interpreters. Programming languages can include staples such as C++, PHP, and more. Developers will choose the right programming code to use based on the project specifications and requirements. ‍


Building software is not the end. Now it must be tested to make sure that there aren’t any bugs and that the end-user experience will not negatively be affected at any point. During the testing stage, developers will go over their software with a fine-tooth comb, noting any bugs or defects that need to be tracked, fixed, and later retested. t’s important that the software overall ends up meeting the quality standards that were previously defined in the SRS document. Depending on the skill of the developers, the complexity of the software, and the requirements for the end-user, testing can either be an extremely short phase or take a very long time. Take a look at our top 10 best practices for software testing projects for more information.


The SDLC doesn’t end when software reaches the market. Developers must now move into a maintenance mode and begin practicing any activities required to handle issues reported by end-users. Furthermore, developers are responsible for implementing any changes that the software might need after deployment. This can include handling residual bugs that were not able to be patched before launch or resolving new issues that crop up due to user reports. Larger systems may require longer maintenance stages compared to smaller systems. ‍
