2 SDLC METHODOLOGIES Introduction According to Russell Kay (2000), “Once upon a time, software development consisted of a programmer writing code to solve a problem or automate a procedure.” Nowadays, different SDLC Methodologies have been created to ensure that the requirements as well user functionalities are meant. These methodologies enforce different degrees-of discipline to the development of different software with the aim of making software development process more effective & predictable. For this reason, various companies around the world utilises different software development approaches in the development of software based on the requirements gathered from the users. This paper will mainly evaluate two types of methodologies i.e., Waterfall and Agile methodologies. Waterfall Methodologies According to the article, Agile introduction for dummies (2008) , waterfall methods refers to a “classically linear and sequential approach to software design and systems development” where every waterfall phase is allocated to a distinct team to guarantee greater project as well as deadline control. This is significant for on-time delivery of the project. Basically, a sequential approach as mentioned above, refers to stage by stage method for project/product building. Lisa Crispin (2014), says, “’I’m kind of sad that “Waterfall” has come to be a synonym for completely dysfunctional software development.” According to this author, waterfall methods are simply set of evidently well-defined phases useful in software development process, with “gates” amid every phase which determine whether the project would progress to the subsequent stage or not (Lisa Crispin, 2014).

3 SDLC METHODOLOGIES The waterfall methods are basically considered as one-of the most widely used direct approaches. These methods have the minimum costs as well as the shortest development times. However, waterfall methodologies does presume an unwavering target since the original stipulations/specifications cannot change. Once a phase is completed in this method, the phase is essentially closed & cannot be re-examined. This drawback has led to general criticism for using this methods in development of software. The process of software development comprises of discovery, as well as the diverse phases of software development which frequently overlap. Critics uphold that this methodology restricts the possibilities to correct mistakes for instance, in case a drawback of the specifications is revealed in the design phase, it cannot be corrected since it’s too late to correct it. Several variants of the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
