SDLC<\/strong> describes phases that provide a model of software cycles and management. Each phase produces what’s needed for the next phase.<\/p>\n

The phases of SDLC are:<\/p>\n

    \n
  1. Requirement gathering and analysis:\u00a0<\/strong>This phase is about focusing on stake \u00a0holders and business. You must ask: who is going to use the program? how are they gonna use it? what data should be in the system?<\/li>\n
  2. Desing:\u00a0<\/strong>Based on the requirements from the previous phase, this one consists in defining the software architecture, such as the software and hardware requirements.<\/li>\n
  3. Implementation\/Coding:<\/strong> This is the most important phase and the longest one.<\/li>\n
  4. Testing:\u00a0<\/strong>In this phase you check if the product was made according to the requirements.<\/li>\n
  5. Deployment:\u00a0<\/strong>The project is delivered to the user. This is a beta testing, the user will evaluate the system and find any errors or bugs. Then\u00a0the developers will debug the program and finally have the official product.<\/li>\n
  6. Maintenance:\u00a0<\/strong>Taking care of the software.<\/li>\n<\/ol>\n

    The models of SDLC are:<\/p>\n

      \n
    1. Waterfall:<\/strong>\u00a0This is the traditional model, it consists in finishing one phase to being with the next one..<\/li>\n
    2. V-Shaped<\/strong>: Is similar to the waterfull, but focuses more in the testing phase.<\/li>\n
    3. Incremental:<\/strong> The cycle is divided in iterations. The software development begins in the first iterarions.<\/li>\n
    4. Prototyping:<\/strong> Consists in creating several prototypes of an application.<\/li>\n
    5. Spiral:\u00a0<\/strong>It combines the waterfall and prototyping models.<\/li>\n
    6. Extreme programming (Agile):\u00a0<\/strong>It uses the incremental model, also it is based on the collaboration of cross-functional teams.<\/li>\n<\/ol>\n

      I think developing software based on these phases is very important to create good quality projects.<\/p>\n
