Software Development Life Cycle: Meet Your Design Goals

“All who have accomplished great things have had a great aim, have fixed their gaze on a goal which was high, one which sometimes seemed impossible.” — Orison Swett Marden.

Every piece of hardware or software goes through a development process that means a series of algorithmic strategies. SDLC is used to specify the phases and steps involved in creating a system in establishing a formal framework and structure.

SDLC stands for Software Development Life Cycle, a structured process that enables the production of high-quality, low-cost software in the shortest possible production time to produce superior software that meets and exceeds all customer expectations and demands.

What Are The 7 Phases Of SDLC?

There are seven phases of the Software Development Life Cycle: 

  • Planning – The project leader evaluates the terms of the project, and cleaning defines the scope and purpose of the application.
  • Analysis –  The team gathers & analyses required materials and how they would go together. 
  • Design – Software developers and architects define the technical details and high-level design of the software system to be able to deliver each requirement.
  • Development – Where the process of creating and building the project starts. If the project is large, the tasks will be divided between team members accordingly. 
  • Testing – Developers test the software multiple times before moving from this stage, as any mistake can completely complicate the project and devalue the company. Any errors or malfunctions are correct in this stage.
  • Deployment: It is when preparations, procedures, ownership transfer, and project deployment are made. 
  • Maintenance:  Finally, when the product is provided upgrades, repairs, fixes, monitoring, etc., after production.

Systems Development Life Cycle is very similar to Software Development Life Cycle. Still, it focuses exclusively on the software development life cycle, helping managers design, develop, test, and deploy information systems to meet target goals. 

Though it sounds simple, it is a complicated and lengthy process where specific programming languages, like Java, Python, C/C++, etc., are used for different software parts. It requires an efficient approach from the developer in the form of the Software Development Life Cycle (SDLC). 

SDLC outlines the task(s) to be complete by a software engineer/developer at various phases. It guarantees that the ultimate product can fulfill customer expectations and fit the total budget.

In which Phase of the SDLC is the feasibility Study Done to Determine?

Must be tested all aspects of the product before deployment. Thus, the Testing Phrase comes before Deployment Phrase and after Development Phase. Therefore, all the probable flaws are tracked, fixed, and retested at this stage. If necessary, we will make all adjustments at this stage. Tests performed by quality assurance (QA) teams may include systems integration and system testing.

Software testers usually break down software testing into four categories:

Unit Testing 

It concentrates on the tiniest component of software design. Thus, software developers test a single unit or a collection of related units. The software programmer generally does this task by examining the results of sample inputs and outputs.

Integration Testing 

The goal is to construct a program structure determined by design using unit-tested components. Integration testing involves combining several elements to generate an outcome.

System Testing

Consequently, developers only pay attention to the necessary input and output, putting less emphasis on internal functioning. Security testing, recovery testing, stress testing, and performance testing are all included in this.

User Acceptance Testing 

The customers do acceptance testing to check whether the delivered products perform the desired tasks, as stated in the requirements. 

Conclusion

In conclusion, the software development life cycle (SDLC) is a framework that helps guide developers through creating and maintaining software. By following the SDLc, developers can ensure that their software is delivered on time, on budget, and with quality.
