There are seven main phases in SDLC: Planning, Requirements Analysis, Design, Coding, Testing, Deployment, and Maintenance. By covering all these phases, the software goes from its initial stage to the continuous improvement stage, ensuring it is keen on successful software development.
Introduction
In the field of software development, the software development life cycle is like the blueprint or the methodology used when one wants to build a house. This is an important process that defines the methodology of development cycles which make it effective and high-quality software, from the idea and even launching and subsequently.
Now let’s see what those seven phases of the software development life cycle are and take a look at how a digital product or application moves from an idea to realizing a working application.
Phase 1: Planning
The first phase of software development, Planning, involves defining the scope and purpose of the software. Just like specifying the destination and the route to get there, we unravel the tasks in front of us at this stage and plan for smooth execution.
Phase 2: Requirements Analysis
Phase 2 of the SDLC, Requirements Analysis, intends to define and document the final users’ precise expectations. Therefore, at this point, the team is concerned with answering the, what are the expectations of our users from our software? This is called requirements gathering.
The project team collects information from stakeholders, including analysts, users, and clients. They conduct interviews, surveys, and focus groups to understand the user’s expectations and needs. The process involves not only asking the right questions but also accurately interpreting the responses.
Phase 3: Design
The Design phase is all about establishing the framework. The development team then goes on to do the software engineering and draft what the software can do and how it should look. This results ultimately in the software product. The emphasis lies on outlining the structure, navigation, user interfaces, and database design in the software. This phase ensures that the software remains user-friendly and performs its tasks efficiently.
What work therefore does the team do? Among key activities are creating data flow diagrams, generating entity-relationship diagrams, designing user interface mockups, and identifying system dependencies along with integration points. They define the constraints of the software in terms of hardware restrictions, performance measurement, and other system aspects as well.
Phase 4: Coding
The coding phase of the Software Development Life Cycle (SDLC) is where engineers and developers get to know the purpose of transforming the design of the software into code. The working environment created in this phase of development wants software to work effectively and be user-friendly. The developers then use either Java or any other relevant programming language to write the code according to the guidelines using the SDD. This document serves as a roadmap and ensures that the subsequent software development is guided according to the vision set in earlier phases.
Phase 5: Testing
The Testing phase of the Software Development Life Cycle (SDLC) can be viewed as an austere quality inspection in a production line. It is where vulnerabilities are revealed. IT testing is intended to bring about an exhaustive examination of the software for bugs or glitches that might have escaped from the process of coding. The task is to make sure that the software works like a dream for the end-user. It may also reveal opportunities for improvement.
Phase 6: Deployment
After carefully building the product, it was time to present that masterpiece to the users by pushing it to the production environment. The Deployment phase is now ready for the careful rollout of the tested and tuned software to end-user customers.
Phase 7: Maintenance
The maintenance phase in the Software Development Life Cycle involves continual support and improvement guaranteeing the software is kept in optimum condition and sustained. It also aims to fulfill the customer’s expectations. During the maintenance phase, this is primarily focused on adaptation to changing software needs. This means taking user feedback on board, unintended failures or issues that arise, plus the addition of features that meet ever-changing user requirements. The process is forever ongoing with adaptations and refinements, just like a gardener tending to his garden.
Conclusion
The seven critical stages of the Software Development Life Cycle have been painstakingly analyzed. Every stage, from planning to maintenance, adds value to the process by fulfilling user requirements with a solution that achieves stated objectives.

In this article, we will witness the seven phases of the software development life cycle and take a look at how a digital product or application moves from an idea to a working application.
Frequently Asked Questions (FAQs)
What is meant by a software development lifecycle?
Software development life cycle (SDLC) is a systematic approach to developing high-quality software it defines seven stages of its life cycle from planning and requirements analysis to design, coding, testing, deployment, and maintenance. This will ensure that software will be effectively created and that continuous improvement is made.
How does continuous delivery fit into the software development lifecycle?
Introduction to Continuous Delivery and its Role in the Software Development Life Cycle Continuous Delivery, or CD, is an SDLC practice that ensures software can reliably be deployed anytime. It consists of automating the deployment process, allowing a software product to receive small and frequent updates.
