All SDLC Phases with Examples and Explanations
Also, deployment entails the implementation of cloud services, hardware, monitoring systems, the configuration of maintenance protocols of complex data, security measures, and data access restrictions. The importance of the software development cycle comes first in any software development process. The quality, lead time, and budget of the output product depend on properly-constructed cycles. This will save the team efforts of programmers, testers, and PMs while increasing the survivability of the product in the conditions of real user operations. Next, we will cover the main phases involved in the System Development Life Cycle to review what each entails.
One of the most important and useful ones in this regard is to develop and design the concept first. The waterfall is the oldest SDLC methodology used for the Software Development Life Cycle. And since the last 20 years, the waterfall methodology has been widely used by developers https://www.globalcloudteam.com/ and software engineers across the globe. Before the 1950s, computing was not elaborate enough to necessitate a detailed approach like the SDLC. However, as the complexity and scale of programming grew, the concept of structured programming emerged within the software industry.
Software development life cycle: process
Some methods work better for specific kinds of projects, but in the final analysis, the most crucial factor for the success of a project may be how closely the particular plan was followed. Synopsys enables you to add security testing to an existing development process, thereby streamlining security throughout the SDLC. Synopsys solutions help you manage security and quality risks comprehensively, across your organization and throughout the application life cycle.
The development team enters the coding phase of the software once the entire architecture, data structures, and functional software designs are ready. These steps remain the same in any software testing process, but their duration may vary as per project size and business requirements. Waterfall phases system development life cycle with example run sequentially, and every stage depends directly on the outcome of the previous phase (i.e., each step “waterfalls” into the next one). In a true waterfall model, the team never goes back a step after finishing a phase, so the model’s success rests on the team’s ability to avoid mistakes.
Different life cycle models may plan the necessary development activities to phases in different ways. Thus, no element which life cycle model is followed, the essential activities are contained in all life cycle models though the action may be carried out in distinct orders in different life cycle models. During any life cycle stage, more than one activity may also be carried out.
Owing to this, it is less preferred among all the models except for by smaller companies who use it in their comparatively smaller project outlines and software. The main point of concern in the Iterative model is the concentration on repetitiveness. In this, the top software developers who are using this particular version of the SDLC Example make it very quickly. This is the reason for its name, as there is a mini-plan for each of the phases, and they waterfall into their next after completion. However, like the identification of the requirements, you have to understand and plan the hand-off process beforehand. Later, after some months of verification and user testing, the support work is passed to a different support team.
What is system development life cycle?
Companies with lower maturity or in some highly regulated industries may require manual approvals during this SDLC stage. Most teams rely on automated tests to speed up this phase, but some manual examinations are also valuable (penetration tests are a good example). If you are considering a transition to DevOps, ensure the team has a firm grasp of SDLC strategies before you introduce radical workflow changes. While there are some drawbacks, SDLC has proven to be one of the most effective ways for successfully launching software products. While it is usually too expensive for the delivery of large projects, this SDLC methodology perfectly works for small or experimental projects. A more concrete vision of project completion is gained via delivering different system variations that may more accurately define the final output.
Intellectsoft works at the cutting edge of SDLC tech and can help you implement it in your organization. Having covered the major SDLC methodologies offered by software development companies, let’s now review whether they are actually worth employing. The Spiral model best fits large projects where the risk of issues arising is high.
Phase 1: Requirement collection and analysis
The beauty of software development is that methodologies can be combined to create a hybrid solution that distinctively addresses the unique needs of a project. Usually, organizations prefer to trust system analysts to make that decision and select the best-suited methodology or combination of models. The biggest difference between the lean methodology and the other methodologies is that the system’s full set of requirements is unknown when the project is launched. As each iteration of the project is released, the statistics and feedback gathered are used to determine the requirements. The lean methodology works best in an entrepreneurial environment where a company is interested in determining if their idea for a software application is worth developing.
Developers must follow the coding guidelines defined by their organization and programming tools like compilers, interpreters, debuggers, etc. are used to generate the code. Different high level programming languages such as C, C++, Pascal, Java and PHP are used for coding. The programming language is chosen with respect to the type of software being developed. Security is critical – especially when the purpose of the system development life cycle is to create software.
Closure, Hand-off, and Support
The internal design of all the modules of the proposed architecture should be clearly defined with the minutest of the details in DDS. For additional information, you can also check out a helpful system development life cycle PDF. The spiral model is a combination of the waterfall and iterative model. Software Development Life Cycle (SDLC) is the process of building software, using 6 phases – Analysis, Definition, Design, Coding, Testing and Deployment. The system analyst is a person who is thoroughly aware of the system and guides the system development project by giving proper directions. He is an expert having technical and interpersonal skills to carry out development tasks required at each phase.
- Crucially, the planning stage involves analysis of the resources and costs needed to complete the project, as well as estimating the overall price of the software developed.
- Different life cycle models may plan the necessary development activities to phases in different ways.
- This is an entertainment application, that is we are applying the computer to do a task (entertain you).
- The system development should be complete in the pre-defined time frame and cost.
- Once the requirement analysis is done, the next stage is to certainly represent and document the software requirements and get them accepted from the project stakeholders.
- In terms of what services to integrate the SDLC Example with, one name is the third-party providers.
It lacks the thorough requirements definition stage of the other methods. Popular SDLC models include the waterfall model, spiral model, and Agile model. The next phase is about to bring down all the knowledge of requirements, analysis, and design of the software project. This phase is the product of the last two, like inputs from the customer and requirement gathering.

Prototyping has different variants which are typically grouped as throwaway or evolutionary. STLC (Software Testing Life Cycle) is a series of activities performed during the testing of software. The purpose of this new UI was to create websites, mobile solutions, and intranets for companies and manage them in an efficient manner. This leads to the creation of more successful versions in the following line.
