The following are all SDLC methodologies:
Agile
Lean
Waterfall
DevOps
1. Provide a brief description of each.
2. Provide a real life example of a company/ project that has use each of these methodologies.
Agile: Agile is a methodology that promotes adaptive planning, iterative development, and continuous improvement. It focuses on delivering value to the customer through working software in short release cycles.
Example: Spotify is a company that has embraced Agile methodology in its software development process. Spotify uses agile practices such as cross-functional teams, daily stand-up meetings, and iterative development to continuously improve its music streaming service.
Lean: Lean is a methodology that aims to eliminate waste and maximize customer value by focusing on continuous improvement. It emphasizes delivering the most value with the least amount of resources.
Example: Toyota is well known for implementing Lean principles in its manufacturing processes. By focusing on reducing waste and optimizing efficiency, Toyota has been able to produce high-quality vehicles at competitive prices.
Waterfall: Waterfall is a traditional linear sequential approach to software development, where each phase is completed before moving on to the next. It follows a fixed plan and does not allow for changes once the project has started.
Example: NASA used the Waterfall methodology in its development of the Apollo space program. NASA followed a step-by-step approach, completing each phase before moving on to the next, to ensure the successful landing of astronauts on the moon.
DevOps: DevOps is a methodology that combines development and operations teams to streamline the software delivery process. DevOps focuses on collaboration, automation, and continuous feedback to deliver high-quality software at a faster pace.
Example: Amazon is a company that has successfully implemented DevOps in its software development process. Amazon's DevOps teams work together to automate processes, improve efficiency, and deliver continuous updates to its e-commerce platform.
