What Is SDLC | Phases And Importance Of SDLC For Companies
As we have seen that business world has changed in the last 6/7 years. The business world is becoming more global day by day and there are several positive as well as negative impacts of this change on businesses. Everything nowadays is shifting towards online platforms from cooking to managing travel plans.
Indeed, almost every business company nowadays is following online platforms to run its business activities. Moreover, every company has software for the management of its activities like an advertisement, event planning, production, sales schedules, product distribution, management, and many more.

Most businesses are following Software Development Life Cycle (SDLC) to get some extra benefits. It's the system that assists in valuable planning before starting the actual work or development. Today we are going to discuss why companies are taking a real interest in SDLC and what the SDLC is.
What Is SDLC
Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high-quality software.
The SDLC aims to provide high-quality software that meets or exceeds customer expectations and reaches completion within times and cost estimates.
Importance Of SDLC For Companies
Software Development Life Cycle provides a simple, friendly, and reliable platform as well as a method to design software applications. As we know that the world is changing into globalization and everybody nowadays is using the internet to meet their needs.
Furthermore, SDLC helps the developers in analyzing needs related to the project. The unnecessary costs during development can be reduced using Software Development Life Cycle (SDLC). It simply provides an initial phase where developers can calculate every cost and can predict costly errors or mistakes.
In addition to this SDLC enables developers to plant everything about the development before its implementation. Moreover, it helps developers in designing and building high-quality software products. Likewise, by analyzing all the requirements and costs related, the developers can easily build the best software products.
Phases Of Software Development Life Cycle (SDLC)
The whole process of SDLC contains four phases which are as follows;
1-Definition Phase
In the first phase of SDLC, the developers mostly analyze the project which is known as Preliminary analysis. After that, they will go for a Feasibility Study and Information analysis. At the end of this phase developers or designers will go for System design which is mostly related to overall performance.
Preliminary analysis;
The process roughly defines the problem statement broadly, its intensity, and the required information for the project. It also defines the boundaries within available financial limits, using different recommendations.
Feasibility study;
If the project justifies being implemented then in this stage the developers will generate a valid reason or justification for the complexity of the project within the defined time and procedure for the implementation of the project. Data analysts, and users (information department) will define the said procedures.
Information analysis;
The step is based on preliminary analysis and a feasibility study. This is the stage that produces the detailed design for the upcoming steps. Functional specifications are defined in this stage in organizational readable languages.
System design;
It's the last stage of the definition phase where system designers are the responsible overall performance of the system. Definition of detailed programming specification within the boundaries of the system. The stage also contains procedures, rules, policies, and plans for training users.
2-Construction Phase
In the construction phase, we perform the implementation of our software. Here we would be fully aware of where and how our software will be implemented. In this phase, we minimize the risk and eliminate it. All the features and components are integrated into an application. In this phase, we perform strict testing, and process optimization is done.
3-Implementation Phase
It is the process of configuring the software for certain conditions of use, as well as training customers to work with the product. This stage begins after the system has been tested and accepted by the company. At the time, a program is installed to support the intended business functions.
4-Operation Phase
It is that phase during construction, in which the flow of the stresses in the medium through which the tunnel advances deviates. It proceeds hand in hand with the monitoring phase, in which the design and all the operating decisions are monitored and perfected.
