![]() ![]() ![]() After the product is delivered, ongoing maintenance and support take place to ensure that the product continues to work as designed. Often, a round of testing happens to ensure that the installation was successful. Release and maintenance: After testing and debugging are completed, the product is released to the client and installed.Defects are found, logged, triaged, and in many cases, fixed. Verification: After the implementation is complete, the software is tested by the testing or QA team to ensure that the requirements and design are met and that the desired level of quality is achieved.Implementation: After the design is approved, implementation or coding of the software according to the requirements and design is done by software developers.It is then reviewed and approved before beginning implementation. ![]() The physical architecture, component architecture, database design, detailed component, module design, and other aspects of design are documented by a software architect or designer. Design: After the requirements are approved, work commences on architecting and designing the product to meet the approved requirements.The requirements are reviewed and approved before exiting this phase. Requirements: In this phase, the expectations and goals of the project are defined, and requirements are analyzed and documented extensively, usually by a business analyst.The six life cycle stages of the original waterfall model are: The phases do not overlap and have specific entrance and exit criteria for moving from one phase to the next. The waterfall methodology (also known as the software development life cycle model (SDLC)) is a more traditional methodology where software development cascades from one phase to the next like a waterfall. Juxtaposed to that, we will cover the most popular frameworks that try to incorporate agile principles at scale–Disciplined Agile Delivery (DAD), Scaled Agile Framework (SAFe), Large Scale Scrum (LeSS), and Waterfall In Part 2, we will first dive into how project managers use the waterfall methodology, which is the most common framework for software development at traditional companies. However, complexity grows as projects and project teams become bigger and new approaches are needed to be agile at scale. These methodologies are usually deployed on a single team level. In Part 1 of the Project Management Blueprint we covered PM methodologies, such as Lean software development, Agile, Scrum, and Kanban, and how they all trace their roots back to Lean Manufacturing. ![]()
