Software development methodologies include the waterfall model and agile development. The waterfall model follows a traditional sequential process of planning, analysis, design, implementation, and maintenance. In contrast, agile development is incremental, iterative, customer-centric and flexible, delivering working software in short sprints of 1-2 weeks to get early and continuous feedback. Both aim to structure the software development process through different approaches.

- 2. Software Development “It’s the process of developing software products in an ordered manner, usually following a certain methodology.” programming + testing + documenting + bug fixing
- 4. Waterfall Model - Traditional Software Development Life Cycle - Cookbook Style - Reflective of Manufacturing Processes - Rigid timeline P A D I M
- 6. - Identifying the Problem - Requirements gathering - Record and Observe - Propose solutions - Identify objectives - Creation of Project Plan Planning
- 7. - Hypothesis Formulation - Analysis of gathered data - Impact analysis - Internal impact analysis - External impact analysis Analysis
- 8. - Designing the Study - Identification of features - Business rules - Diagrams and Layouts - Entity Relationship Diagrams - Process Maps - Pseudocode Design
- 9. - Actual Development - Coding - Integration and Testing - Bug Fixing - Alpha and Beta Releases Implementation $ ruby > require ::File.expand_path('.. /config/environment', __FILE__) run Rails.application //= require turbolinks //= require_tree . require 'rails/all' ….. …..
- 10. - Support and Continuity - Evolution of software - Updates - Performance evaluation - Validation Maintenance
- 12. Agile - Incremental and iterative development - Flexible with changes - Customer centric - Blurs lines between development phases - Value-driven
- 13. Sprints - a Sprint is a work cycle of agile - 1-2 weeks long - iterative - each sprint produces workable product
- 14. Sprints - sprints are done per feature - customer/client is heavily involved - quality assessment at the end per sprint
- 17. Software Development Waterfall - Traditional Model - Sequential - Plan-driven - Focused Agile - Incremental - Value-driven - Customer-centric - Flexible
