   • SDLC V-Model - Software Engineering

     The V-model is a type of SDLC model where the process executes in a sequential manner in a V-shape. It is also known as the Verification and Validation model. It is based on the association of a testing phase for each corresponding development stage. The development of each step is directly associated with the testing phase. The next phase starts only after completion of the previous phase i.e., for each development activity, there is a testing activity corresponding to it. 

     The V-Model is a software development life cycle (SDLC) model that provides a systematic and visual representation of the software development process. It is based on the idea of a “V” shape, with the two legs of the “V” representing the progression of the software development process from requirements gathering and analysis to design, implementation, testing, and maintenance.

     • Accurately define and refine user requirements.
     • Design and build an application according to the authorized user requirements.
     • Validate that the application they had built adhered to the authorized business requirements.
     • It is easy to manage due to the rigidity of the model. Each phase of V-Model has specific deliverables and a review process.
     • Proactive defect tracking – that is defects are found at early stage.
     • Where requirements are clearly defined and fixed.
     • The V-Model is used when ample technical resources are available with technical expertise.
     • Small to medium-sized projects with set and clearly specified needs are recommended to use the V-shaped model.
     • Since it is challenging to keep stable needs in large projects, the project should be small.

   • Software Processes in Software Engineering

     Software processes in software engineering refer to the methods and techniques used to develop and maintain software. Some examples of software processes include:

     • Waterfall: a linear, sequential approach to software development, with distinct phases such as requirements gathering, design, implementation, testing, and maintenance.
     • Agile: a flexible, iterative approach to software development, with an emphasis on rapid prototyping and continuous delivery.
     • Scrum: a popular Agile methodology that emphasizes teamwork, iterative development, and a flexible, adaptive approach to planning and management.
     • DevOps: a set of practices that aims to improve collaboration and communication between development and operations teams, with an emphasis on automating the software delivery process.

     Each process has its own set of advantages and disadvantages, and the choice of which one to use depends on the specific project and organization.

     Software is the set of instructions in the form of programs to govern the computer system and to process the hardware components. To produce a software product the set of activities is used. This set is called a software process.   

     Software Development : In this process, designing, programming, documenting, testing, and bug fixing is done.

     Components of Software :  There are three components of the software: These are : Program, Documentation, and Operating Procedures.

     • Software Specifications – In this process, detailed description of a software system to be developed with its functional and non-functional requirements.  
     • Software Development –In this process, designing, programming, documenting, testing, and bug fixing is done.  
     • Software Validation –In this process, evaluation software product is done to ensure that the software meets the business requirements as well as the end users needs.  
     • Software Evolution – It is a process of developing software initially, then timely updating it for various reasons. 
     • Size and Cost –Day to day growing complexity and expectation out of software. Software are more expensive and more complex.  
     • Quality –Software products must have good quality.  
     • Delayed Delivery –Software takes longer than the estimated time to develop, which in turn leads to cost shooting up. 
     • The term “software crisis” refers to a set of problems that were faced by the software industry in the 1960s and 1970s, such as:
     • High costs and long development times: software projects were taking much longer and costing much more than expected.
     • Low quality: software was often delivered late, with bugs and other defects that made it difficult to use.
     • Lack of standardization: there were no established best practices or standards for software development, making it difficult to compare and improve different approaches.
     • Lack of tools and methodologies: there were few tools and methodologies available to help with software development, making it a difficult and time-consuming process.
     • These problems led to a growing realization that the traditional approaches to software development were not effective and needed to be improved. This led to the development of new software development methodologies, such as the Waterfall and Agile methodologies, as well as the creation of new tools and technologies to support software development.

   What is SDLC in software development?

   • The goal of SDLC is to minimize project risks through forward planning so that software meets customer expectations during production and beyond. This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure. Why is SDLC important?

   How does SDLC work?

   • SDLC works by lowering the cost of software development while simultaneously improving quality and shortening production time. SDLC achieves these apparently divergent goals by following a plan that removes the typical pitfalls of software development projects. That plan starts by evaluating existing systems for deficiencies.
