![]() Because design is completed early in the development lifecycle, this approach lends itself to projects where multiple software components must be designed (sometimes in parallel) for integration with external systems.Except for reviews, approvals, status meetings, etc., a customer presence is not strictly required after the requirements phase.Testers can prepare test scripts from requirements documentation while coding is underway. For example, business analysts can learn about and document what needs to be done, while the developers are working on other projects. Throughout the development effort, it’s possible for various members of the team to be involved or to continue with other work, depending on the active phase of the project.Progress is more easily measured, as the full scope of the work is known in advance.This makes planning and designing more straightforward. Developers and customers agree on what will be delivered early in the development lifecycle.There are good things and bad about the Waterfall approach. There is also typically a stage gate between each for example, requirements must be reviewed and approved by the customer before design can begin. In a true Waterfall development project, each of these represents a distinct stage of software development, and each stage generally finishes before the next one can begin. In this methodology, the sequence of events is something like: Waterfall is a linear approach to software development. Having been involved in software development projects for a long time, here are my thoughts on the strengths and weaknesses of each. Agile: a specific type of Rapid Application Development and newer than Waterfall, but not that new, which is often implemented using Scrum.īoth of these are usable, mature methodologies.Waterfall: (ugh, terrible name!), which might be more properly called the “traditional” approach, and.The two basic, most popular methodologies are: 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. ![]() 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. One of the first decisions we face for each of our project implementations at Segue is “Which development methodology should we use?” This is a topic that gets a lot of discussion (and often heated debate). ![]()
