Through an eight-week Red Hat Open Innovation Labs residency, Lockheed Martin Aeronautics replaced the
waterfall development process it used for F-22 Raptor upgrades with an agile methodology and DevSecOps practices that are more adaptive to the needs of the US Air Force.
Perhaps the most significant change in the last decade has been the shift from
Waterfall development methods to Agile.
Some programs have implemented a "Water-Scrum-Fall" approach, where Agile sprints (short development cycles) are integrated into a
waterfall development method.
AFCU had been using a
waterfall development process, where programmers would create a long laundry list of changes over months, and possibly years, before implementing them.
During the certification process, SGS-TALV Saar evaluated the relevant parts of Express Logic's modified
waterfall development process for ThreadX SMP, with phase overlap and phase blending, to ensure that best development practices were followed during these phases:

This research has been presenting a model, Agile-Waterfall Hybrid Development Model which allows the characteristics of the
waterfall development model and agile development model.
Waterfall development is named so because of the linear flow of water in a waterfall.
Waterfall development, the traditional sequential process of design, is rapidly becoming antiquated, while agile development, characterized by self-organizing, cross-functional teams, has become mainstream.
Such rectification is impossible to achieve in
waterfall development process depicts weakness of traditional model.
