SDLC & its Key Points 

Software Development Life Cycle or SDLC is the process of development of information system based on analysis, design, implementation as well as maintenance. In simple words, it is the process or method that involves various mentioned processes for the creation of high-quality software. It is the second layer of open system interconnection or OSI model of network communication. It basically assures the flow of data properly from one channel to the other. SDLC is very important as it not only breaks down the entire life cycle of the software development and makes it much easier for the programmers to work on every phase and therefore evaluate all the parts of software development. During the period of the 70s and 80s, major software engineers had conducted multiple studies and research for better quality and reliability of various software products. It had a common motive, i.e. software development. The result of so much hard work was the introduction of SDLC and various other methods of development based on SDLC.

Secondly, SDLC is a process document and should never be considered as a technical document. Thus, it is not a technological topic and the readers would easily be able to understand its basic concepts along with its approach. Whatever time and effort you invest in understanding SDLC would surely be one of the best investments of your business.

What are the stages of SDLC?

SDLC follows the below steps involved in the method of software development as follows:

  • Analysis of actual requirement
  • Planning
  • Software design such as architectural design
  • Software development
  • Testing
  • Deployment

What is the most important stage of SDLC?

Planning and analysis is considered to be the most important phase of SDLC. The majority of the companies invest only 10-15% time in this phase and as a result, they fail because they did not plan and analyze the product needed to be invented. Therefore, it is highly advisable to spend the majority of the time in these two phases to reduce failure and expenses of producing a needy product or a service. This stage should never be ignored for the betterment of your business as well as the desired results.

Therefore, SDLC is an essential tool that offers many advantages. Few of such advantages that are beneficial for you are as follows:

  • Shares an exact view of the entire system & resources, timeline as well as goals.
  • Easy and proper evaluation of the cost and growth of the developed system.
  • It helps by sharing reviews for ensuring the reliability as well as the quality of the final product.
  • Not only involves comprehensive steps, but also helps to exercise control over the complex and large projects.
