Software development life cycle methodology Sample Clauses

Software development life cycle methodology. In software engineering, a system development methodology is regarded as a framework that is used to structure, plan, and control the process of developing an information system. To design and develop the colMOOC conversational agent module, the project research methodology was based on an agile software development life cycle model (SDLC), which is often used in the learning sciences to design technological or pedagogical interventions (▇▇▇▇▇▇ & ▇▇▇▇, 2015). Many alternative approaches have been developed in the past in order to counter the rigidness and lack of flexibility found in waterfall-like SDLC models. Along with the rise of the incremental and rapid application development (RAD) models, a manifesto for agile software development was introduced by software developers, aiming to bring together the best traits of other agile-like models into one framework. Following this, agile methods of development have become increasingly popular (▇▇▇▇▇▇▇▇ et al. 2009). Nowadays, there are numerous variations of the agile model sharing the same principles and traits, such as the emphasis on simplicity, the prioritization of user satisfaction, the frequent requirements updates and software deliveries, the existence of self-organizing project teams and the regular discussions that take place emphasizing team improvements. The agile SDLC was selected because of its strengths, such as the increased flexibility and development speed offered. In general, most agile methodologies have emerged from the increasing need to match the speed at which technology evolves. A key aspect setting it apart is its dexterity in developing software at high speed, with software products being deliverable in weeks instead of months. This is possible due to the model emphasis on collaborative efforts and documentation. Another main advantage of the agile model is its increased flexibility since it can be combined with other existing models. It has the capacity to deliver systems whose requirements go through constant changes while, at the same time, demanding strict time limits. Furthermore, the agile model is often praised for its high degree of user satisfaction and user- friendliness, reduced error margins, and the ability to incorporate solutions to address the needs of mutable requirements. In that manner, it is considered a client-centric model, which advocates “short iterations and small releases” in order to obtain feedback on what has been accomplished. With the feedback that is ...
