<\/span><\/h2>\nThe SDLC or <\/span>software development life cycle<\/b> can be best defined as a systematic process and protocols that ensure the development of a smooth working software with all the necessary and additional features and an intuitive user interface.<\/span><\/p>\nThe cycle ensures that the ultimate digital product fulfills the client’s & development team’s expectations by executing planned functionalities, speed, performance, etc., done during the different phases of the SDLC.<\/span><\/p>\nThe cycle starts with collecting ideas for the final product and ends with deploying the absolute software. However, the maintenance phase continues for the entire life to keep it updated with the latest technology and tools.<\/span><\/p>\nHave a look at the 7 Stages of Software Development Life cycle (SDLC)<\/b><\/p>\n\n- \u00a0 \u00a0 \u00a0 <\/span>Ideation\/Requirements Collection Stage<\/b><\/li>\n

\nLet us study each of these stages in detail.<\/span><\/p>\nStage-1: Ideation or Requirements Collection Phase<\/b><\/h3>\n
<\/p>\n
The first stage of the SDLC mainly involves a detailed discussion between the project leader and the investment firm. As a client, you must communicate your issues or pain areas in which you are investing. Based on the detailed discussion, a rough outlook of the final software gets developed.<\/span><\/p>\nThe project leader further communicates with the final users, industry leaders, etc., to gain insights into the software’s principle and additional features. A significant deal of research is done to find and add innovative features to the project in this phase.<\/span><\/p>\nThus, essential aspects of the software development project like the proposed features, functionalities, etc., are realized. However, the team finalizes them in the feasibility stage.<\/span><\/p>\nStage-2: Feasibility Assertion Phase<\/b><\/h3>\n
Once done with the stage of ideation, the project enters into the feasibility stage and is judged on the following factors to find its feasibility.<\/span><\/p>\n\n- Features Integration:<\/b> If the software involves new and innovative features integration,\u00a0 the team looks for compatible technology, stacks, etc., and realizes whether they can be achieved or has to be dropped.<\/span><\/li>\n
- Project Time:<\/b> Based on the complexity level, the panel of experts realizes the time frame within which it can be delivered to the client and conveys the same.<\/span><\/li>\n
- Project Budget:<\/b> Depending upon the planned features and expected total working hours, the project gets checked under the budget constraints.<\/span><\/li>\n
- Legal constraints:<\/b> As software caters to universal consumers, the offered features’ legalities are checked against concerned nations for which it is getting designed.<\/span><\/li>\n<\/ul>\n
Stage-3: The Designing Phase of the SDLC<\/b><\/h3>\n
<\/p>\n
This stage of the software development life cycle is all about preparing the framework or the software’s exterior designs. An experienced team of designers is handed over the task in the form of a document that contains all the required specifications (called RSD) either in HLD or LLD format.<\/span><\/p>\n\u00a0<\/span><\/p>\n\n\n\n\n High Level Design (HLD) document<\/b><\/p>\n<\/td>\n | \n Low Level Design (LLD) document<\/b><\/p>\n<\/td>\n<\/tr>\n\n\n It contains identity and description of all the modules.<\/span><\/p>\n<\/td>\n | \n It has a functional description of all the modules.<\/span><\/p>\n<\/td>\n<\/tr>\n\n\n Offers detailed relationship between diverse modules<\/span><\/p>\n<\/td>\n | \n Offer details focused on the interface.<\/span><\/p>\n<\/td>\n<\/tr>\n\n\n Employs architectural diagrams and technology details<\/span><\/p>\n<\/td>\n | \n Employs database tables for the designing team to understand and work.<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\u00a0<\/span><\/p>\nThe expert team of professionals carries out the daunting task of designing based on the RSD. The color combinations, font size, logo placement, CTAs (if any) are all accomplished such as they resonate with the investing firm and core features.<\/span><\/p>\nStage-4: Coding Phase of the Software<\/b><\/h3>\nThe coding phase of the SDLC is all about a team of experienced developers giving life to the designed product. The development team writes code either from scratch or relies on frameworks to speed up the process. The most prolonged phase of the software development life cycle gets done in the preplanned programming language.<\/span><\/p>\nStage-5: Quality Assurance and Testing of the developed product<\/b><\/h3>\n<\/p>\n Once the developer’s team completes the software’s coding, it gets checked for bugs and issues by a panel of testers. The quality assurance team ensures that the developed software successfully meets the promised features.<\/span><\/p>\n\u00a0In case of any detected issues, errors, bugs, etc., the quality assurance team conveys it to the concerned developers for debugging of the software. As testing is crucial for identifying the undetected bugs, let’s briefly look at the different ways in which it is performed.<\/span><\/p>\n\n- Unit Testing:<\/strong> Each module or group of interconnected modules gets tested for expected outcomes.<\/span><\/li>\n
- Regression Testing:<\/strong> IT is performed with the integration of each new module.<\/span><\/li>\n
- Alpha Testing:<\/strong> The developed software is tested for all possible bugs and errors.<\/span><\/li>\n
- Beta testing:<\/strong> The software is released for a limited number of users to check its real application performance.<\/span><\/li>\n<\/ul>\n
Performance testing, Object-oriented testing, etc., are also standard ways of detecting bugs in the software.<\/span><\/p>\nStage-6: Deployment of the final software<\/b><\/h3>\nWhen finally passed by the development team, the software is released into the user’s hand. Despite the quality assurance, the developed digital product may exhibit undetected bugs at this stage. Thus, the next stage is all about clients’ delight by improving the software performance.<\/span><\/p>\nStage-7: Maintenance phase of the software<\/b><\/h3>\nBased on the client’s feedback and software performance, the development team performs maintenance of the software in the following ways:<\/span><\/p>\n\n- Debugging any detected flaws.<\/span><\/li>\n
- Integrating additional features to improve the performance of the software.<\/span><\/li>\n
- Upgrading the software for the updated platforms.<\/span><\/li>\n<\/ul>\n
The maintenance of the software depends upon the development of firm policies and contracts signed. Ideally, investing firms should opt for a minimum of 3 months of maintenance time to avoid any additional charges for updating the software.<\/span><\/p>\nBy now, you must have gained good command over the <\/span>software development life cycle<\/b>. However, do you know about the popular <\/span>SDLC models<\/b> that a custom application development firm follows?<\/span><\/p>\n \n | | | |
