    The second method that will be proposed is the agile methodology. The agile methodology proposes alternatives to traditional project management. Agile development focuses on keeping code simple, testing often, and delivering functional bits of the application as soon as they are ready (TechTarget, 2014). One goal of agile development is to build upon small-client-approved parts as the project progresses, as opposed to delivering one large application at the end of the…

    Nt1310 Unit 5 Project Management Methods

    The waterfall method is one of the main planning techniques for a project. It is very important for every project to be planned well. If a project manager does not plan every part of the project before starting the project, failure is almost certain. The waterfall method is one of the simplest planning methods for software projects, or any project for that matter. It is comprised of five main phases where “the output of each phase becomes the input for the next.” 1 These phases are Analysis, Design, Implementation, Testing, and Maintenance. The analysis phase is a description of the software that needs to be developed. The design phase is the planning and solving of problems for your solution. The implementation phase is the actual implementing of your software. The testing phase is the verification of your software. This is the phase where you make sure everything is completed and all problems have been solved. The last phase, the maintenance phase, is when the team goes back in when needed to update the software implemented. This method is an easily implemented method that still goes over main objectives that other methods do. If a company follows the method correctly, they should decrease the amount of errors exponentially. The main problem most projects run into is not following their original plan.…

    Systems Development Life Cycles

    The systems development life cycle (SDLC) is also known as the waterfall model. The systems development life cycle is a SDM (systems development methodology) that consists of seven phases. The seven phases are in a specific order that is completed phase by phase. The first phase is planning. The planning stage is where an outline is drawn up for preparations. During this phase a systems analyst, who may work for the company or be an outside consultant, will outline a proposed system, develop a budget, and create a detailed development schedule. To help make the decision, the company will perform four types of feasibility analyses: (1) technical, (2) economic, (3) operational, and (4) schedule. The second phase of the waterfall model is system analysis. The systems analysis phase follows the planning phase. In this phase a systems analyst would work with a company to understand the problem fully and detail the requirements of an information systems solution. This phase uses many tools and techniques, including requirements gathering, structured…
