PROJECT MANAGEMENT METHODOLOGIES

WATERFALL MODELAGILE MODEL

Page 3: Models in project management_Agile and Waterfall

WATERFALL MODEL• The waterfall model is a traditional model and the first model introduced

• The model develops systematically from one phase to other in a downward fashion, like a waterfall

• Follows Linear-sequential life cycle• Very simple to understand and use• Each phase must be completed before the next phase begins and there is no overlapping in the phases

• Waterfall model works well for smaller projects where requirements are very well understood.

AGILE MODEL

• Combination of iterative and incremental process models

• Process adaptability and customer satisfaction• Agile described as a freeform of software design• Software developers works on small modules at a time

• Customers feedback occurs simultaneously with development

Page 6: Models in project management_Agile and Waterfall

• Agile can be especially beneficial in situations where the end goals of projects are not clearly defined 

• Agile is an excellent option for experimental software design

• Agile follows the sprint mechanism

WATERFALL VS AGILE

WATERFALL

• Rigid & inflexible design model

• Planned approach• Fixed requirements• Adaptive approach• Best for static projects• Estimated timeliness & budgets 

AGILE

• Flexible design model

• Unplanned approach• Evolving requirements• Predictive approach• Best for smaller and unpredictable projects

• Unpredictable timeliness      & budgets 

Page 9: Models in project management_Agile and Waterfall

WATERFALL

• Impossible to make changes

• SDLC is followed as a whole once

• Linear – sequential 

• Customers are involved at early & delivery stages alone 

AGILE

• Changes are done at any stage

• SDLC is followed at each sprint

• Incremental – iterative

• Very high degree of customer involvement
