Benefits of Agile<\/p>\n

A student sent email to me: \u201cWhat are the advantages of Agile method over others? How do I compare this method with others?”<\/p>\n

 <\/p>\n

Answer: Please read my previous articles on Agile software development. As I have mentioned previously, Agile is very good for small project where requirements are not well-defined and may change often. With this method, you must break requirements down into small tasks that can be easily managed, and measured. Just like eating an elephant, you cannot swallow everything so you must eat one bite at a time.<\/p>\n

With Agile method, you develop software incrementally and release to customer one task at a time. By doing that you will not be late and customer will have something to use quickly rather than have to wait until the entire project complete. By having small release, you can only get late as much as few weeks, which can be easy to fix.<\/p>\n

Because you only estimate works required for each iteration, your estimation is more accurate. (most people can estimate the amount of works in two to four weeks) Because customers must involve in the project, developers can talk to them to understand their needs so change can be made quickly and effectively.<\/p>\n

Because the team is self-organized, everybody is equal so no \u201cego\u201d issue and no \u201chero\u201d issue in this type of work. The team divide the works among themselves so it limit any unfair distribution or any distractions from bureaucracy. Team members can concentrate on their works according to a commitment among themselves.<\/p>\n

With \u201cPair programming\u201d. Two people are better than one so when a something is needed, they can response quickly and more efficiently. With Agile, every day the team must meet for a short period to discuss progress and issues so things can be solve quickly and everybody know about the progress of the project.<\/p>\n","protected":false},"excerpt":{"rendered":"
