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. this approach emphasizes the rapid delivery of an application in complete functional components. 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.
using a gantt chart allows you to map subtasks, dependencies and each phase of the project as it moves through the project life cycle. let’s hypothesize a simple project, then plan and execute it with the waterfall phases that you just learned. a waterfall project is broken up into phases, which can be achieved on a gantt chart in the waterfall software. managing a project with the waterfall method is all about structure. you want a tool with the storage capacity to hold all your documents and make them easy to find when you need them.
all the documentation and requirements needed to address for the project can quickly become overwhelming. waterfall methodology is all about structure and moving from one phase to the next, so breaking your project into milestones is key to any waterfall plan. assigning is a major step in managing your waterfall project and needs to happen efficiently. having a means to quickly copy projects is helpful in waterfall methodology, as it jumpstarts the next project by recreating the major steps and allowing you to make tweaks as needed. the important difference to remember is that a waterfall project is a fixed, linear plan. using a project management software is a great way to get the most out of your waterfall project.
the waterfall methodology. waterfall is a linear approach to software development. in this in software development, it tends to be among the less iterative and flexible approaches, as progress flows in implementation: the implementation phase is when programmers assimilate the requirements and specifications, . much like construction and manufacturing workflows, waterfall methodology is a sequential design process. this means that as each of the eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are completed, the developers move on to the next step.
1. requirement gathering and documentation 2. system design 3. implementation 4. testing 5. delivery/ the waterfall approach to systems analysis and design wass the first established modern the steps include both the agile and waterfall methodologies carry their own set of implementation: in many cases,,
