Changing Application Development Needs

With increase in development services, IT sector has seen a blossoming with new methodologies. Software development is a significant group that has a great impact in all walks of our life. IT sector is an evolving field that sees various developments each day. This model is actually an organized strategy. It helps in carrying out the steps in software application development life cycle in a conventional, efficient, and repeatable method. The methodologies that were successful earlier now seem outdated with the rise in demand for better functional software. Over the past years, a number of best practices have slowly been evolved among enterprise software developers. Majority of methodologies applied for application development are similar in one way or the other.

The earliest methodology is waterfall method that follows a sequential step-by-step method right from start of this process to maintaining the developed application. This model does not cater to changes that are sure to occur during the this cycle. Advancement to waterfall method is the spiral model that is more iterative methodology. This team starts with a small set of requirements for each phase of development. The spiral way helps them in adding the additional requirement that arise after each phase is complete. Spiral method is suited for projects that are large, expensive, and complicated. The hybrid model of software development is in fact a mixture of all methodologies appropriate for very large projects. With adaptive nature of hybrid methodology, it is easy to reduce over-budget and delayed schedule issues.

These were some of the conventional methodologies. The introduction of novel 'light-weight' agile model for software development was in view to adapt the rapidly changing business requirements. It is more adaptive that being predictive in matters of software development that are apparent to change with time. Agile methodology helps businesses to respond quickly to market changes. The time thus saved is utilized in developing features that will bring the most value to the business.

There are many things to be considered before adopting a methodology. The choice should not be based on 'it is always the same we have done', rather should look into the extent of project requirement, its flexibility, and the time for product and services to market including the cost effectiveness.
