According to Andrew Walker and Paul Scott, authors of the book ‘Beyond Agile’, about half of all projects fail. Of these failed projects, 32% fail due to project requirements and 23% fail due to poor communication (Gitnux). Many CIOs have also said that limited resources and overly complex projects make it difficult for them to deliver reliable and bug-free software. This situation often leads to delivery delays and increased costs.
When work is done without a clear process and testing is done haphazardly, management problems become common. This is where the Software Development Life Cycle (SDLC) plays an important role. SDLC provides a step-by-step methodology that helps teams complete projects faster and improve software quality. The concept of SDLC originated in the 1960s when large companies were looking for ways to manage their complex software projects more efficiently.
This article explains why SDLC is so important in today’s software development world, where speed and reliability are paramount.
What is SDLC?
The Software Development Life Cycle (SDLC) is a clear, step-by-step methodology for creating software. It guides the process of planning, building, testing, deploying, and maintaining software. The SDLC helps teams develop software that meets business requirements, adheres to quality standards, and improves over time.
Companies that follow a proper SDLC complete their work much faster—often up to 70% faster—and have fewer bugs in their software.
1. Requirements Gathering
- Discussing with users to understand the problem.
- Collecting ideas
- Create a list of software
Objective: To understand what needs to be built and why.
2. Analysis
- Translate business requirements into technical requirements
- Define project goals, scope, and limitations
- Prepare a clear Software Requirements Specification (SRS)
Objective: To transform ideas into a clear plan.
3. Planning
- Decide on budget, timeline, and team members
- Identify risks and follow regulations
- Choose the right tools and technologies
Objective: To plan the work in a smart and cost-effective way.
4. Design and Architecture
- Create design and architecture documents
- Develop simple UI/UX designs and screen layouts
- Plan databases, APIs, and system integrations
Objective: To determine what the software will look like and how it will function.
5. Implementation and Coding
- Write clean and readable code
- Implement backend logic, APIs, and databases
- Set up tools and version control systems
Objective: To build the software step by step.
6. Testing and Quality Assurance
- Test every part of the software
- Test for speed, security, and bugs
- Use manual and automated testing
Objective: To ensure the software works well and securely.
7. Deployment and Launch
- Test the application in a staging environment
- Deploy the application using automated tools
- Prepare user guides and support documentation
Objective: To launch the software smoothly.
8. Maintenance and Support
- Add new features and updates
- Fix bugs and improve performance
- Perform regular system health checks
Objective: To keep the software up-to-date, secure, and functional.
Why SDLC is More Important Today Than Ever Before
Today’s fast-paced online world is moving at a rapid pace. If a product is slow, insecure, or of poor quality, it can hurt a business. A clear and repeatable SDLC helps create software that performs well, is secure, and launches on time – without wasting money. At SKAD IT Solutions, SDLC is more than just a step-by-step process. It’s how we think and act. Whether you’re creating a brand new concept or improving an existing system, we help you focus on tangible results rather than just getting the job done.
Understanding the Software Development Life Cycle (SDLC)
The Software Development Life Cycle (SDLC) is a step-by-step methodology that software developers use to plan, build, test, and release software. It helps developers work in a structured manner, ensuring that software is developed on time and functions properly. This process keeps the project transparent, simple, and well-managed. In this detailed blog, we have explained the various stages, phases, and types of the Software Development Life Cycle. This will help you understand how software is developed from start to finish in a clear and simple way.
What is the Software Development Life Cycle (SDLC)?
The Software Development Life Cycle (SDLC) is a clear, step-by-step method for creating and maintaining software. It starts with an idea and continues after the software is released. According to experts, the SDLC shows teams what to do and when to do it, and how to check the progress of the work. It helps save time, money, and effort.
In 2025, the SDLC typically divides work into simple steps such as planning, gathering requirements, designing, coding, testing, deploying, and supporting. These steps do not always follow a straight line. Teams often go back to previous steps and improve them as they learn new things. The SDLC works with different work styles, including fast and slow methods, and companies adapt it to their needs.
According to experts, some key characteristics of SDLC include:
- It is an iterative process, not something done only once.
- It encompasses everything from the conceptual stage to after the software is launched.
- It helps reduce costs.
- It decides role.
The names of the steps may vary, but the goal remains the same:
- Planning: defining problem
- Design: Planning for system architecture and data flow.
- Development: writing code step-by-step.
- Testing: Bugs can be solved by testing.
- Deployment: It reduces the software.
- Maintenance: It is the major point for SDLC.
Experience shows that the SDLC works best when it is flexible. Teams adjust the amount of writing, reviewing, and testing based on the level of risk in the project. For example, a small internal tool may require less documentation than a public or legal system. However, the steps of the SDLC are used in both cases to ensure clarity and organization.
