Computers and software are now an essential part of our daily lives and existence yet most of us do not know the technicality behind every software. They play a key role in day-to-day life but cannot answer all the questions we ask from them. The desire to get the best software has led to a number of custom software development services or solutions.
Many software development companies have a standardized development approach that is utilized in all stages of software development life cycle (SDLC). The fixed model follows specific steps that ensure every step is a success when developing software. Every phase in the development cycle has a significance depending on the product under development.
What is SDLC?
Software development life cycle is that process that a software development firm uses to develop a custom software with the best quality and within the shortest time possible. The idea is to utilize minimal resources within a small budget. SDLC involves an extensive plan on how to develop, maintain, change, and replace the software system.
SDLC is defined through various stages that include design, building, testing, planning, and deployment.
Competent software development firms will make sure the entire development team goes through the following phases during software development.
Data Gathering and System Analysis
To design the most efficient software development solutions information gathering is critical. Developers use this phase to analyze all the worries of the owners and eventual users of the project.
A meeting usually takes place between the managers and stakeholders and all other users in order to capture the needs of possible users. System analysts will use this data to get the best information about the likely environment and people who will use the system. As part of SDLC, the basic information gathered in this phase custom software developers will define input and output of the system.
The possible system and its software backend are finalized based on the information that was gathered earlier. The specific role of designing is the design of hardware and system needs as well defining the entire system architecture. In addition, testers will design system-testing strategies where they come up with a robust testing solution to make the final product strong.
They also define the testing strategy that will guarantee the best software in their category.
When the system design blueprint is ready, software companies that deal with software development solutions will identify several units and start the coding process. The coding phase usually takes more time than any other phase in software development life cycle.
After the coding stage, software developers will test against the expected system requirements to make sure that it works accordingly and to the needs of the client. Subjecting the product to all manner of testing at this stage is okay.
Start with unit testing, system testing, integration testing, acceptance testing, and all manner of non-functional tests to make sure it can withstand challenges.
Once the testing is satisfactory, the product is taken to the client for their use. With the software on site, the client will take it through beta analysis and testing. For the end user or owner of the software, make sure you make any recommendations for any change that is necessary.
Make note of any bugs and let the custom software development company know and fix it with the help of their professionals
System Support and Maintenance
When the software is in the hands of the user that is when actual real issues emerge and has to solve almost immediately. System design life cycle does not end the moment the client pays the last deposit, in fact that is when system maintenance takes effect.
How SDLC Works
The most important thing about SDLC is the lowering of the cost of software development while improving its quality using the most available resources. Through the SDLC divergent approach, all the usual bureaucracy is no longer part of the design and development process.
As indicated above, the idea is to start by identifying the system requirements of the proposed product. Developers will first look at the existing system and its deficiencies and thereafter define the requirements of the new system. Then it will follow through the SDLC developmental stages.
Benefits of Using SDLC
Software development firms that use SDLC gives its developers the highest level of freedom during documentation. The entire team will sit and agree on the best way to achieve their main objective. Everyone gets to know the costs and resources needed.
Failure to follow any of the SDLC implementation process means you have not taken into account the needs of the customers and all users. This mistake will lead to poor understanding of the system requirements the moment the system is launched.
We can now say that we have seen the relevance of having a team that faithfully follows the SDLC process; the final product should be as good as the intentions are the analysis stage. However, most technicians think of SDLC to be a technical aspect of software development whereas it is a process document.
