METHODOLOGIES FOR SOFTWARE PROYECTS (Jesus Lopez)

1. TRADITIONALS

   • types
     • Waterfall
       • it uses a sequential order; each stage must be finished before next one can start. The project is reviewed in each stage to ensure is developed according to the requirements
     • Prototyping
       • It is based on construction of a software prototype that is built quickly for the users can try it and to give feedback
     • Incremental
       • In this model the requirements are classified into subsets, the model includes several development cycles, like a “ multiple waterfall”
     • RAD
       • The objective of this model is to develop systems faster and produce results with better quality to linear traditional model
     • Spiral
       • This model repeats all the stages for a certain period of time until the requested system is completed, the emphasis is to evaluate risks
   • definition
     • sequence of steps that requires Defining and documenting a set of requirements at the beginning of a development project.

2. AGILE

   • definition
     • These methodologies are highly flexible and agile, that allows to adapt the software to requirements that going to appear throught the development process
   • types
     • Scrum
       • This model is focused on projects where the initial planning is difficult. The software is developed by a team in stages called sprints
     • Kanban
       • The workflow is organized on a board or table, this shows every detail within the software project, when there is a new task for to do, a new “card” is created
     • Extreme Programming
       • This methodology allows frequent interaction between teamwork and the customer, his emphasis is on discovering the simplest thing that will work, all time small improvements are being includes
     • Lean
       • small work teams very trained do any task in short time. Learning, quick reactions and empowering the team are the fundamental aspects
     • Crystal
       • The focus of this methodology is on how the individuals interact Each other. The team have freedom to develop their own processes
