agile and waterfall methodologies

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.

we compare the benefits and drawbacks of using two well-known software development methodologies, waterfall and agile, and lay out when it might be more suitable to use one over the other – or combine practices of both – for your product initiative. the agile development methodology takes a collaborative approach to software development where requirements and solutions evolve through iterations. if you’re in an organization that has strict processes that they have to adhere to, trying to introduce agile processes cross-functionally could be challenging, and so the waterfall methodology will be more suitable.

it’s actually quite common for product teams to use some combination of both waterfall and agile development methodologies in order to deliver a solution in a way that optimizes the team’s time and resources and maximizes end user satisfaction. it’s important to note that the benefits of an agile development methodology can still be reaped even if your team is taking on a project that succumbs to strict regulation. at the end of the day, you need to evaluate the workflow, processes and structure of your collaborating teams, the budget that you have, and timelines to determine if either waterfall, agile, or a “wagile” hybrid works best for you.

the waterfall methodology. waterfall is a linear approach to software development. in this methodology, waterfall is a liner sequential life cycle model whereas agile is a continuous iteration of development and testing in the software development process. in agile vs waterfall difference, the agile methodology is known for its flexibility whereas waterfall is a structured software development methodology. the two main development methodologies are agile and waterfall. they are commonly applied to software development, and thus, project management as well. the main difference between agile and waterfall is that waterfall projects are completed sequentially whereas agile projects are completed iteratively in a cycle., waterfall methodology, waterfall methodology, agile methodology, agile vs waterfall methodology, waterfall model. 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. agile helps complete many small projects; waterfall helps complete one single project.

the key characteristic of the waterfall development methodology is that each step in the software in agile methodologies, leadership encourages teamwork, accountability, and face-to-face traditional waterfall project methodologies have been used for years to implement complex and large-scale enterprise,
