Recommended: Strengths and Weaknesses of Waterfall Approach for Software Development

Software Engineering Assignment Name: M Asif Razzaq Class: MIT-3 Roll No: mitm-f16-054 Submit To: Sir Usama Liaquat WATERFALL MODEL The waterfall model is the classical model of software engineering. This model is one of the oldest models and is widely used in government projects and in many major companies. As this model emphasizes planning in early stages, it ensures design flaws before they develop. The waterfall method does not prohibit returning to an earlier phase, for example, returning from the design phase to the requirements phase. However, this involves costly rework. Each completed phase requires formal review and extensive documentation development. Thus, oversights made in the requirements phase are expensive to correct later. The waterfall model has its weaknesses, it is instructive because it emphasizes important stages of project development. The waterfall model is a linear sequential (non-iterative) design approach for software …show more content…

Waterfall model cannot be tracked back. It is used for large projects. It was purposed by computer scientist Winston Walker Royce in 1970. Incremental Model Incremental model consists of following steps: Requirement, Specification, Architectural design, Implementation, Maintenance and retirement. It is combination of undeviating and iterative model. It can straightforwardly accept change. It was purposed by IEEE in 2003 due to defects in waterfall model. As waterfall is not suitable for all models.

    766 Words  | 2 Pages

    Agile project management is an iterative approach to the planning and monitoring of project processes. Agile projects are conducted in smaller tranches called iterations with each of these iterations closely reviewed and critiqued by the project team (employees, representatives of the clients etc.). The knowledge gained from this process is then used to ascertain the next steps of the

    The project is going I am working is almost in the finish stage it is going into the production phase means getting to the live so that the users can able to use the application. After the developing the total code it will go to the testing phase where the testers will check the code is working properly without any errors actually the testers task is to check the code and submit to the developers if they found any errors or mistakes or else they will send the code to the production phase to deploy in the server to check the application.

    Waterfall No. 1 Georgia O’Keefes painting Waterfall No.1 was one of three paintings she devoted to depict a waterfall near the Lao Valley in Hawaii. This one like the rest of them were all done on a white canvas with oil paints. The canvas came about when O’keefe visited Hawaii in 1939 and like the name suggests it is a depiction of a beautiful waterfall. This was new territory for O’keefe when she painted this, as she was most famous for depictions of the arid southwest. The lush tropical sights of Hawaii were a completely opposite compared to her previous pieces.

  • Compare And Contrast Waterfall And Agile

    1825 Words  | 4 Pages

    In the waterfall method, the steps have to be finished iterative, meaning the next step cannot be started until the previous step is completed. Once the current step is completed, then the next step can be started and so on. The customer does not get a working build during any of the steps and cannot make any changes in the scope at all. Once all steps are completed, the end result is given to the customer and then they can deploy and hope it does what they are needing it to do. If any of the steps need to be changed, then the whole process will need to be restarted from the beginning and the process began again. In agile methods, the process is more flexible. This method is flexible and can allow changes after each iteration. The goal of each iteration is to provide a working build so that the customer can give feedback on it and changes can be made, if needed, so that all requirements are met, or if requirements have changed since the initial build of the

  • Systems Development Life Cycle ( Sdlc )

    829 Words  | 2 Pages

    The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

    The projects in today’s world are given a lot of importance and it will continue to grow in the coming years. There are a lot of companies which do not have production, but all of them do have projects. There are a lot of books which have been published on which related to planning and managing the projects. The one of the most important one was published by the author Eli Goldratt in his book ‘Critical chain’. This book basically talks and shows how the application of theory of constraints in the field of project management. The novel is basically based on one of the MBA classes in America where a number of ideas are developed in discussions among the students and the lecturers. The lecturer is basically fighting for a tenure with the president of the university who expects a downturn in the executive MBA. The lecturer who teaches project management has a word with one the senior colleagues and project management was the right topic to teach.

    Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.
