Introduction

• Agile and Waterfall are the two most
  prominent methods to develop software and a
  debate rages about which one is better. Well,
  heres a breaker. We have listed a clear
  description of these methodologies along with
  their strengths and weaknesses that will help you
  choose between the two.

Understanding Agile

• Agile is often seen as a solution to the
  drawbacks of the waterfall methodology. Rather
  than a sequential design process, the Agile
  methodology works on an incremental approach.
• Developers begin with a basic project design,
  and then work on small units. The work on these
  units is done on a weekly or monthly basis, and
  at the end of each week or month, project
  priorities are assessed and tests are done. These
  units allow for errors to be found, and customer
  feedback to be combined into the design before
  the next unit is run.

Strengths of Agile Methodology

• The Agile methodology allows you to make changes
  even after the initial planning. Re-writes to the
  program can be made whenever the client decides
  to make changes.
• It also allows you to add features that keep you
  updated with the advances in your industry.
• It also allows clients to give their feedback and
  makes sure that they get the product they
  desire.

Weaknesses of Agile Methodology

• If you use a less successful project manager, the
  project is likely to come in late and over
  budget.
• As the initial project lacks a stable plan, the
  final product can turn out to be different than
  what was intended.

Understanding Waterfall

• Waterfall methodology is a sequential design
  process. This means that everything is done step
  by step. The eight steps- outset, initiation,
  breakdown, design, construction, testing,
  implementation, and maintenance have to be
  completed one after another. Once a step has been
  completed, developers cant go back to a previous
  step without discarding the entire project and
  starting from the scratch.

Strengths of Waterfall Methodology

• The waterfall methodology allows for the ability
  to progress upon the existing program in the
  future as it stresses careful record keeping.
• The clients will have knowledge of the size,
  cost, and timeline for the project. They will
  have a clear idea of what their program will do
  in the end and theres no room for uncertainty.
• Its strong documentation allows for minimal
  project impacting the case of employee turnover.

11
Weaknesses of Waterfall Methodology

• Developers cant move back to a previous stage
  and make changes once a step has been completed.
• If initial requirements are faulty in any manner,
  the entire project is ruined as this methodology
  relies heavily on requirements.
• If a change is needed or a requirement error is
  found, the project has to be started from scratch
  with all new code.

Conclusion

• Both Agile and waterfall methodology have
  their respective strengths and weaknesses. The
  decision of choosing between the two relies on
  the context of the project. Will your project
  need frequent changes? If yes, go for Agile. And
  if you know exactly what you need, maybe
  waterfall is the better choice. If youre
  uncertain and confused, merging the aspects of
  both agile waterfall methodology is an effective
  way to develop the best possible software process
  for your project.
