One Pager Cheat Sheet

• This tutorial offers a comprehensive overview of the Waterfall and Agile development methodologies, discussing each of their advantages and drawbacks as well as the types of projects for which each of them are best suited.
• The Waterfall methodology sequentially arranges distinct phases of software development from requirements to maintenance, provides estimations of the project's cost and effort, and is plan-driven with any changes requiring a restart.
• The Waterfall method is a plan-driven process that allows for the entire budget of a software development project to be estimated at the start, but any later changes during the course of the project would require a restart.
• The Waterfall methodology has straightforward planning and design, better design overall, and defined roles and scope of work, but can struggle with changes, customer engagement, and large-sized projects.
• One of the signficant advantages of the Waterfall methodology is the ability to provide clear roles and ensure better communication and collaboration, leading to successful projects.
• Agile software development provides an iterative and cross-functional alternative to the Waterfall method, where sprints of a fixed duration determine the deliverables and adjust to changes as they come.
• Agile software development involves breaking projects into sprints of fixed duration and prioritizing deliverables based on customer-determined business value.
• The Agile methodology can provide faster software development, increased customer satisfaction, and better communication, but requires strong commitment from the customer and can lead to additional costs.
• Customer involvement in Agile methodology can be beneficial but can also be a disadvantage when the customer is unwilling or unable to become actively involved.
• For choosing the right methodology for a project, it is dependent on the type of project, the organization, and the team; however, Waterfall is best for stable projects with a tight deadline, budget, or regulatory requirement, whereas Agile is the way to go for projects that are more flexible or require collaboration.
