agile methodology and waterfall methodology

if this is not something you’ve worked with before, a definition of development methodology is in order; put very simply, it’s a way of organizing the work of software development. this is not about a style of project management or a specific technical approach, although you will often hear these terms all thrown together or used interchangeably. having been involved in software development projects for a long time, here are my thoughts on the strengths and weaknesses of each. there is also typically a stage gate between each; for example, requirements must be reviewed and approved by the customer before design can begin. rather than creating tasks and schedules, all time is “time-boxed” into phases called “sprints.” each sprint has a defined duration (usually in weeks) with a running list of deliverables, planned at the start of the sprint. if all planned work for the sprint cannot be completed, work is reprioritized and the information is used for future sprint planning.

agile relies on a very high level of customer involvement throughout the project, but especially during these reviews. first, we change the game a little (which is what most software development organizations do) by defining our own process. our modifications include use of prototyping where possible to provide the customer a better view of their finished product early in the design/development cycle. after the primary framework of the application is completed per high level requirements, we continue to develop and also to reach out to the customer for refinement of requirements. although we are starting to see mass adoption of various agile methodologies in the enterprise (even dod and federal agencies), there are still many organizations that are slow to make the change. it is also very common for organization to transition into more of a hybrid agile approach that combines aspect of both agile and waterfall. the project management institute (pmi) that developed the project management body of knowledge (pmbok) guide collaborated with the agile alliance to bundle the two guides in one offering to help organizations, managers and leadership increase agility in the development process.

the traditional waterfall methodology for software development is rapidly losing its popularity as agile methodology is now being increasingly adopted by companies worldwide for software development. on the other hand, agile development methodology follows a linear sequential approach while providing flexibility for changing project requirements, as they occur. very intuitive as an explanation between each as they apply to project development but in some instances, depending on the technology in which the project relates, i’m not sure agile can be used on all instances. i was always try to get clarification on the waterfall model and agile method of project management but unable to understand from other portal.but today i get my 100% understanding towards above methodology.

it is very useful and easy to understand… keep posting similar kind of articles for who new to this domain or wiling to learn new skills. turns out agile is far less secure than waterfall, in that the qa cycle leaves out much of what was tested in previous module sin order to get the code, whitehat security states “for every 100kloc (100 thousand lines of code), a monolithic application will have an average of 39 vulnerabilities whereas a microservice application will have an average of 180 vulnerabilities. the other piece left out above in the article, is that training and documentation are, from the experience of many – lacking or non-existent. but hey, you’ll save time, and only the customer will be less secure, not your problem anymore, on to the next startup gig i’d venture guess. users of this website are not authorized to redistribute, reproduce, republish, modify, or make commercial use of the information without the written authorization of flatworld solutions pvt.

waterfall is a liner sequential life cycle model whereas agile is a continuous iteration of development the waterfall methodology. waterfall is a linear approach to software development. in this methodology, the two main development methodologies are agile and waterfall. they are commonly applied to, agile vs waterfall methodology, agile vs waterfall methodology, waterfall methodology in project management, similarities between agile and waterfall, compare waterfall and agile software development methodologies. agile is an incremental and iterative approach; waterfall is a linear and sequential approach. agile separates a project into sprints; waterfall divides a project into phases. test teams in agile can take part in requirements change; test teams in waterfall do not get involved in requirements change.

the software development process is divided into different phases in the waterfall model while agile the key characteristic of the waterfall development methodology is that each step in the software agile method advantages. the methodology is focused on the client process. it makes sure that the client,
