Agile Methodology vs Waterfall Methodology: Which is better for your Project?

The popularity of standard waterfall techniques for creating applications is swiftly decreasing as newer Agile strategies are progressively implemented. So just exactly what are these techniques, and which is superior?

Waterfall Methodology

The waterfall method has each stage in a manufactured product’s life span occurring chronologically, so that development streams progressively down through each stage similar to a waterfall. The waterfall technique was passed down to business software programmers from other sectors where, after a specific stage of development was finished, it would have been very expensive or unrealistic to turn around and change things. The waterfall method was only systematized once people awakened to the fact that there were other viable project management techniques.

A number of popular waterfall techniques are utilized on IT jobs, which includes the UK-based PRINCE2 and PMI PMP, which carries more worldwide recognition. Generally speaking, these techniques have phases that cover what steps to take before beginning a job, during the starting stage, the planning stage, the implementation stage, and the finishing stage. They also include a sequence of procedures for handling job packages, exclusions, reports, hazards, and other problems.

Advantages of the Waterfall Process

  • Possible problems can be identified and addressed during the design stage if needed, before any code is generated.
  • The designing procedure is usually well-documented, as this technique puts more importance on recordkeeping of things like specifications and blueprints. A lot of companies are comforted by this.
  • As the waterfall method is a chronological process, it may be less complicated for non-programmers or those with little experience in software design to grasp. Teams typically prefer this strategy.

Downsides of the Waterfall Process

  • Many times the clients who are paying to have software built for them aren’t sure of precisely what they want ahead of time and are unaware of the possibilities of the available technologies. This style of operating is not a good match for this technique.
  • Strategy designers are frequently unable to predict issues that might develop after they’ve executed their designs.
  • Requirement changes (such as those caused by the implementation of new technologies, market fluctuations, or changes in company objectives) are difficult to integrate with the waterfall technique, and typically there are time-intensive change management processes to perform during these occasions.
  • The procedure lacks self-motivation.

Agile Methodology

Agile program development techniques (like Scrum) are those that do away with a straightforward, chronological strategy and replace it with a step-by-step, repetitive one. Rather than including large amounts of planning and designing ahead of time, Agile methods provide room for shifting needs over a period of time through the use of interlocked teams (made up of planners, developers, programmers, and testers) that work together on consecutive repetitions of a product over predetermined cycles of time (or time boxes). As it’s completed, work is listed in a stockpile that is categorized by its specific level of priority according to its user worth.

These cross-functioning teams are self-structuring and typically include a representative of the business (the product owner). The focus of the technique is on effective interpersonal communications and brief feedback cycles. The target of every successive repetition is to generate an operational product that is ready for demonstration to potential investors. Feedback is then provided for integration into upcoming repetitions.

Agile developed from a variety of open software techniques that gained ground during the ’90s as alternatives to more complex, rule-based techniques such as waterfall. The Agile Manifesto for Software Development, which was composed in 2001, is a testament to how much focus Agile puts on value.

Advantages of the Agile Process

  • Operational software is produced significantly faster, and consecutive repetitions may be provided regularly, at a steady rate.
  • There is more interpersonal collaboration among designers and the company.
  • Modifications to the project may be integrated at any stage in the procedure, even later on.
  • It provides the possibility of constant enhancement for live programs.
  • It is very unambiguous.

Downsides of the Agile Process

  • Agile techniques (such as Scrum, Crystal, Kanban, et al) in many cases are more challenging to learn than linear kinds, in the beginning specifically.
  • Due to the heavy amount of importance placed on producing operational software, there is sometimes a feeling that record keeping may be ignored. Proper attention should be placed on providing documentation to whatever entity requires it, but if the technique is improperly used, this doesn’t always happen.
  • If used poorly, Agile may cause additional shortcomings within large companies or contradict long-term company procedures.

When Agile is Superior to Waterfall

Many cutting-edge businesses today are major supporters of Agile software strategies, and that’s understandable. The fact is that technologies, companies, and market segments are constantly in flux today, and as a result software design has to be flexible first and foremost. Agile techniques are more adaptable than waterfall techniques, meaning that clients’ needs are more inclined to be fulfilled. Even during periods of change, the continuous emphasis on value ensures that whatever has already been provided should have at least been worth it. Plus, the flow that an Agile method like Scrum generates boosts the development of driven, enthusiastic teams in which output improves with time.

When Waterfall is Superior to Agile

There are still situations in which a waterfall approach can be more beneficial – for instance, simple projects where necessities never change and there is almost no ambiguity – although these situations are steadily becoming harder to find. Additionally, if a company and the employees working on the assignment are not developed enough for an Agile method, it may be better to employ conventional project control strategies.
