Overview

Software development has spurred over business objectives since technology took its place. Businesses began to realize that software can create an altogether new space to interact with other stakeholders. There are many ways for a developer to choose a particular path. But it’s also important to know the basics for the one who just wants the end product, i.e., software.

People usually are now ambiguous about selecting between waterfall vs agile. The developmental methodologies, specifically a way of organizing the process of software development. These are the most popular ones with a usable and mature methodology. This guide will help you to understand these two and decide which one is better for you.

Statistics

Before going into the subjective part, let’s get to know the facts and researched surveys agile and waterfall.

According to Ambysoft’s Survey, the agile method is 64% successful while waterfall has a 48% of success rate. The prior has a failure rate of 8% and the latter one has 18%.

Capterra concludes that 71% of companies are now implementing Agile. Harvard business review states that 60% of companies experience revenue growth and profits after incurring the Agile approach.

Understanding Agile Methodology

Understanding Agile MethodologyThe Agile methodology is an iterative process of managing projects. The agile model phases break up into several various phases, involving constant collaboration with stakeholders. It manages continuous improvement on every stage.

There are six parts of the Agile model stages.

  • Concept
  • Inception
  • Iteration
  • Release
  • Maintenance
  • Retirement

Further, the Agile iteration usually takes two to four weeks with an end date. The workflow of Agile iteration typically flows into five steps. Plan Requirements, Develop product, Test software, deliver iteration and incorporate feedback. Each stage mentioned above has several iterations.

Characteristics of the Agile Methodology

After getting to know the meaning of Agile Methodology, here is a list of characteristics that make Agile distinctive.

  • Before launching the product officially, the team scans the software for changes according to minimum requirements. The step is called MVP(Minimum Viable Product), this is tried by the customer by giving feedback.
  • The development is in various phases, also known as an iterative process rather than one linear sequence.
  • The teams using the Agile framework focuses on the deliverable value that is tangible to be measured and also check the feedback regularly.
  • Unlike many other methods, Agile allows the teams to have cross-functions with maximum possible interactions between them and with customers.
  • An agile team has its focus only on what’s needed to be delivered.

Reasons to Use Agile Methodology

Reasons to Use Agile MethodologyThe Agile Diagram follows a new era framework, with rapid technological advances. There are various reasons why companies widely use the Agile Method and why one should adopt the one. This is the list of reasons or advantages of Agile methodology.

Satisfied Customers

As we have seen, Agile involves the customers in its developmental process. Without assuming what users want, the Agile method understands how their demands can be met. This method values the opinions and ensures that the final product is what they need.

Agile results in tailor-made software delivery, which is likely to increase user interface and hence boost up customer retention.

More Adaptability

Due to its iterative process, the central theme of Agile is flexibility. The teams using this method are responsive to change and modifications, as its process allows the changes to be incurred without any disruption.

Nothing is rigid, the priorities and delivery can be adjusted without any chaos. More adaptability, suggests that the team can deliver accountability and manage clients’ changing demands.

Guaranteeing Quality and increased predictability

Using an iterative process for managing the projects allows improving the quality at every step. Consistent focus on improvement and quality management is the fundamental principle of Agile.

Agile teams work in a sprint, meaning a short period with a fixed duration. This process makes it easier to predict the outcome. Also, estimating costs is easier and efficient.

More predictability, lesser risk

Assessing the progress during sprints creates better visibility into the projects. Regular checking can help with spotting potential obstacles and tackling minor issues. It also facilitates effective risk management and gives the process a greater chance of software success.

Improved communication

Agile teams prioritize regular interaction with more face-to-face communication. Teams usually conduct daily meetings to ensure and check everyone’s progress. Through regular communication, they cease any type of confusion to successfully achieve their objectives.

Better communication helps in having a singular approach for the team and better teamwork invites better project delivery.

Possible fallbacks of Agile Methodology

Possible fallbacks of Agile MethodologyUnderstanding both Agile Advantages and Disadvantages is important. Being aware of possible fallbacks helps you in eliminating them while practicing the process.

Poor Resource Planning

With Agile it is difficult to predict required costs, time and resources because the teams don’t know when and how it will end. With consistent openness to changes, the teams won’t have any idea of their result.

Output’s fragmentation

Incremental delivery is one of the basic features of agile methodology. However, it helps to bring success in the market easily but also fragments the output due to different cycles. If not careful enough this can be a huge disadvantage of using Agile

No potential Project end

Agile requires minimal planning at the start as it allows modifications in between the process. Although, this minimal planning results in an unclear picture of the final product and can incur unexpected functionality.

Limited Documents

The agile method is less detailed as the documentation happens throughout the project rather than at the beginning.

Difficult to measure

The tracking process is about looking across cycles, a “see-as-you-go” nature. This means that one can not set many KPIs at the start of the project. This iterative process makes its measurement difficult.

Understanding Waterfall Methodology

Understanding Waterfall MethodologyThis one is the classic model used for system development to create a system with a linear and sequential approach. As the term suggests, the model develops systematically going from one phase to another with a downward flow.

Unlike Agile, this model employs a planned process. The Waterfall model phases are divided into different phases such as the output of one phase being used as input for the next phase. It requires that every phase should be completed before another phase, to avoid overlapping many phases together.

The waterfall model diagram works in sequential phases of 7 levels. These levels are: –

Requirement Gathering: All the required resources and demands are documented clearly at the time of planning.

Analyses Read: To define the schemas, models, and business rules, the listed requirements are analyzed carefully.

Designing System: Waterfall makes the team design the software architecture based on analyzed requirements.

Dividing the structure: Implementing, developing, and planning the software in small units with functional testing is part of the waterfall methodology.

Integration and testing: Integration here means creating a link between each unit of development with the previous phase. And when the integration is done, there is a test conducted for reviewing the whole planned test.

Deployment of the system: This step is about making the product live in production environments with all the planned steps after functional and non-functional testing is completed.

Maintenance: The final step is about fixing the issues and modifying the possible issues before implementation.

Why is the Waterfall Method a Good Choice?

Why is the Waterfall Method a Good ChoiceReleasing on a particular sequence of steps, with a phase initializing another phase, this structure proves itself to be the best choice for smaller projects. This section gives you an in-depth insight into why this methodology does the best.

Uses Clear Structure:

Unlike Agile methodology, waterfall focuses on a clear and defined set of steps. Teams must complete an entire step before moving to another one. This clear sequence eliminates any type of blocks and half-finished assigned months are likely to be sidelined. Also, a clear vision means intuitive project delivery.

Measurable End Result:

With proper planning, Waterfall allows the team to have a predictable end goal and having greater commitment. For small projects clear goals from the beginning are good. Waterfall keeps the focus on the end goal with a concrete plan.

Ability to transfer information nicely:

The waterfall is planned in detail. This method invites a clear transfer of information at each step. Each team for each phase has access to prior information.

Disadvantages of employing waterfall methodology

Disadvantages of employing waterfall methodology copyThe waterfall method has recently faced much criticism because of its rigid nature. It makes it outdated for contemporary technological demands. These limitations are what you can expect if you choose to go for a waterfall development process.

  • Modifications are difficult

With an entirely traditional form, this method is with no room for unexpected changes or modifications. This one is the most expected limitation of the waterfall. For small projects, the waterfall can be a good choice but larger projects need to be modified regularly.

  • Doesn’t involve the end-user

One of the worst fallbacks of the waterfall is that it eliminates the opinions of the end-user. The main objective is to help internal teams to move from one phase to another easily but avoid external factors. This can lead to lesser user satisfaction.

  • Delays the testing after completion

Unlike Agile, in the waterfall the testing and feedback are after the software is developed. This can make the procedure clear but also makes the required modifications chaotic.

Analyzing Agile vs Waterfall

As we have comprehended the basics of Agile and Waterfall, let’s now create a sense of their comparison.

The first step to compare the Agile vs Waterfall model is to understand when it can be used. For example, when one requires a high-priority core enterprise like a system of records, this system won’t require frequent changes. On the other side systems like accounting demand modifications. The level of frequency of required modifications differs in the areas in which these two methods can be used.

The second step is the core difference of their approach. The agile vs Waterfall approach works with the understanding that one is an iterative process and the other is a linear approach. Taking into consideration the agile framework, it includes gathering, designing, development, testing, and review. The application software development is done with incremental changes.

It can be different from waterfall in the way that waterfall’s requirements are baselined. The functional product is delivered in every phase after which another starts.

The Agile vs Waterfall analogy also differs in the degree of flexibility offered. The project’s requirements decide the level of flexibility it wants. As Agile offers more flexibility it is good for large projects and waterfall is suitable for smaller ones.

Further, they differ because of the types of teams working on it. The agile project works with a cross-functional team. There are interchangeable duties with great teamwork. On the other hand, Waterfall’s teams have people with different functional skills working together.
