Recommended: Advantages and disadvantages of waterfall model

QUESTION 1:
Describe the traditional waterfall model. Identify and explain each of development phases. State the advantages and disadvantages of implementing this model.

1.1 TRADITIONAL WATERFALL MODEL

The waterfall model is a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards like a waterfall through the phases of system engineering, requirements analysis, design, construction, testing, installation and maintenance. Waterfall model also refers to a linear-sequential life cycle model. Each phase in a waterfall model must be completed fully before the next phase can begin. Basically, waterfall model is used for small project and there are no uncertain requirements. At the end of each phase in waterfall model, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. The testing phase starts only after the development is complete.
Waterfall model is used when the requirements are very well known, clear and fixed. Moreover, when product definition is stable, waterfall model will use. Waterfall model also will used when the technology is understood, no ambiguous requirements, ample resources with required expertise are available free, and the project is short.

Besides that, systems engineering also focused on the design and management of complicated engineering projects, across a wide range of engineering specialties. Not only that, systems engineering is a combination of technical and project management skills required to complete multidisciplinary projects. All tools such as modelling, simulation, requirements analysis, project management and building consensus is required to complete a complex

  • 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 system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.

    Most of the software development projects change just during the development is in process. This is the reason that agile methodology is best for these projects. There is a room for change in them. Software developers follow these methods and this is the reason that they have further modified these methods according to the different types of projects they confront in their development time.

    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.
