SDLC – Major Advantages and the Popular Models

  • November 21, 2023
  • 9 min read

The Software Development Life Cycle (SDLC) is an organized and well-defined methodology that aids in the production of high-caliber software by engineers. It also provides a number of phases, including designing, developing, testing, deploying, and maintaining. SDLC has numerous advantages. The SDLC model generally involves the procedure of developing the software as per the business understanding and current requirements.

To put it in clear terms, SDLC is a very practical, systematic, and scientific approach adopted by the development teams to design, develop, test, and maintain system software applications. It provides the developers with a framework to complete the design as well as the developmental phase.

Let us have a look in detail at the major advantages and the various models of SDLC.

Advantages of SDLC

Let us now decode the advantages of SDLC.

  • Structured Approach: SDLC offers an organized method for developing software. It helps developers plan and arrange their work more effectively. In addition, this method guarantees the timely delivery of software, boosts productivity, and reduces errors.
  • Risk Management: Risks related to software development can be organized and managed with the use of the SDLC. Moreover, developers can lower the risk of software development by taking action to mitigate such risks as soon as they are identified early in the process.
  • Consistency: The SDLC offers a standardized structure and approach to guarantee consistency in software development. Additionally, by maintaining consistency, the software is made of higher quality, and the client’s expectations are met in the final output.
  • Collaboration: By giving team members a uniform application structure and language for communication, the SDLC promotes teamwork. This partnership guarantees that the final product satisfies the client’s expectations and contributes to the general improvement of the software.
  • Cost-effective: By utilizing prototype tools like Figma and others to find possible problems early in the development process, the SDLC lowers development costs. Furthermore, developers can take action to lessen vulnerabilities by detecting them early. It lowers the development’s overall cost.

Types of SDLC Models

The heavyweight (predictive) and lightweight (agile) software development lifecycle models are the two main types. Heavyweight procedures suggest that the scope of work is predefined in advance. They are also known as predictive for this reason. They demand extensive documentation and a major input from the programmers. Historically businesses have opted for a heavyweight strategy when organizing and simplifying large-scale projects. However, these days, SDLC models of this kind are less common. Project efficiency is reduced as a result of the suggested needless bureaucracy.

These days it is replaced by lightweight or agile processes, also called adaptive. They are an excellent middle ground between an excessive amount of tight discipline and none at all. In terms of the Software Life Cycle, agile involves a lot less paperwork.

An adaptable method, for instance, takes into account different customer requirements, such as the necessity for constant application modifications. Meanwhile, as unanticipated changes arise, the complexity of predictive SDLC models only increases.

When working with big teams of specialists and well-defined requirements, heavyweight techniques make sense. Agile techniques function best when there are frequent changes made to the original plan and when teams are composed of up to ten members.

Predictive SDLC Models

Predictive (heavyweight) models include:

  • Waterfall
  • Iterative
  • Spiral
  • V-shaped

These are the most common models apart from some of the other ones. These models are pretty similar to each other.

Adaptive SDLC Models

When working with big teams of specialists and well-defined requirements, heavyweight techniques make sense. Agile techniques function best when there are frequent changes to the original plan and when teams are composed of up to ten members.

Realizations of Agile models include:

  • Scrum
  • XP
  • Kanban

NIRA Systems offers state-of-the-art SDLC models that are best suited for your business and operational efficiency.

To Sum Up

According to a study nowadays, more than 70% of organizations employ an agile approach. The top software development companies apply the best SDLC models that are easy to understand. At present the companies are using over 50 SDLC models for speeding up the development process and delivering exceptional results. If we take into account, the size of the engineering software market, it was valued at $20.95 billion in 2020. The product lifecycle management market size worldwide was estimated at $26.86 billion in 2021 and is projected to grow at 8.6% CAGR from the year 2022 to 2023. The global market size of software development tools is forecasted to reach US$9944 million by 2027.

We at NIRA Systems offer our expertise and help implement the latest state-of-the-art SDLC models to streamline your product development.
