Software Application life-cycle - Research Paper Example It also depends upon the time and budget constraints of which of the life-cycle model will be appropriate to adapt. This paper will introduce and compare two of the life cycle models; the waterfall and the agile model. The models will be compared and analyzed in the context of the mobile software development project. This is to propose the most adequate model for a mobile software development project (Schach, 2010). Comparative Analysis of Life-Cycle Models The waterfall life cycle model is a sequential process model. It is a step-by-step development model starting from the initial design phase and ending to the completion phase (the maintenance phase) (Schach, 2010, p. 53). The phases of the model are interdependent on each other as the next phase begins only when the previous phase is ideally completed. Adapting waterfall model for the mobile software development project could be worth it as it may include the detailed stages of requirements analysis, design, and implementation, gi ving ideal completion to the mobile software (Munassar & Govardhan, 2010). Contrary to the waterfall model is the iterative incremental life cycle model, which is based on correspondence and integration (Bittner & Spence, 2006, p. 143). The iteration model leads a mobile project incrementally, which means that it has more compatibility that the waterfall method to adapt changes in the initial requirements’ stage. It is a reversible model looped to the adjusting and modifying code source requirements (Gomaa, 2011). The waterfall life cycle model is a more detailed and apprehensive model for mobile software development (Mall, 2009). It is a more comprehensive model than iteration to complete a mobile development project. However, it could be more expensive than the iteration model as it is less flexible to adapt changes. The rigidity of the model is what makes it a more complex model to adapt (Schach, 2010). Iterative incremental model is more flexible as compare to the waterfa ll model. More specifically, for the short term mobile projects, iteration model is supple to adapt. The mobile software development often requires changes in each development stage (Schach, 2010). Likewise, there are feedback inputs from stakeholders or users that could come at the beginning or at mid or ending stages of design and implementation. This requires incorporation of the design changes or requirements changes, on where iterative incremental model is more effective to adjust (Schach, 2010). Due to sequential rigidity, the waterfall life cycle model gives less space to the mobile clients. It gives less room to the customers to assert their initial requirements (Schach, 2010). On the other side, iterative incremental model gives much choice to users to put on their initial requirements. As the iterative model affords the low cost on changes or modification so it allows users to give major demands or requirements. This is how iteration model is more market oriented than wate rfall. It is a model which is customer focused than waterfall model (Gomaa, 2011). The waterfall lifecycle model can take more time than iteration model to complete a mobile software project (Munassar & Govardhan, 2010). Comparatively the waterfall model requires larger set of data than iteration in proceeding and completing a project. As each phase is more detailed and more apprehensive so it makes the waterfall model a time consuming model (Mall, 2009). Apart from all, iterative increme

Learning to swim at the age of 15 Essay Example | Topics and Well Written Essays - 500 words

Learning to swim at the age of 15 - Essay Example It was on a rampage to literally swallow me and end the basis of my life. Terrified, I buried my sharp, long nails into the back of my friend’s neck attempting to hold on, but when we thumped into the wet surface, the vicious coerce tore me away and inundated me into the deep, bleak, blue water. At that instant, a stream spurted rapidly up my nose and I began to dread. In the aspiration of reaching the surface, I hastily kicked my legs like a tantrum-throwing two-year infant. Regrettably, every time my head dashed up, the water immediately hauled me back down. I then had nothing else to do but wait for all I could. Seconds later, I caught a glimpse of my friend pacing towards my course. He withdrew me from the aqueous tank and expressed regret for what had happened by then. Then, I confessed that I was fifteen years old and did not know how to swim. I had made up my mind to learn how to swim. Period. Clock struck two o’clock – it was Thursday afternoon, my swim classes at the YMCA commenced. Pacing towards the building, I swiftly halted when I saw my classmates there. It shocked me in entirety. Neither of the swim class attendees looked more than eight years old nor was their physique disproportional with their age group. I nonchalantly entered the water, whilst attempting to blend in, but within seconds, the seven elf-sized heads turned to look at me. I did not know what to do at that point in time. For all the goodness that could have happened then, the instructor arrived and started the class. We embarked by learning how to cup our hands and rotate our arms. She even described the basis of our arms pretending to be made like the bus’ wheels that go â€Å"round and round.† Afterwards, she demonstrated to us as to how to place our bodies before diving as she held her hands above her head, palms touching, and her arms touched her ears all this while. She also gave us kicking advice in order to move quicker. She told us to do small quick kicks without
