A slideset presenting traditional software development vs agile software development

1. Software Development
Methodologies

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

3. Waterfall Model
&
Agile

4. Waterfall Model
- Traditional Software Development Life Cycle
- Cookbook Style
- Reflective of Manufacturing Processes
- Rigid timeline
P A D I M

5. Planning
Analysis
Design
Implementation
Maintenance

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

11. Planning

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
