Agile vs. Waterfall: Which Methodology is Right for Your Project?

You’ve got a software project that you’re ready to bring to life. Awesome! This is an exciting time, and you may be chomping at the bit to get things rolling.

However, before you jump in, you’ve got to decide on something else—the software development methodology that will guide your project. Believe it or not, that decision could make or break your product in the end.

Software development methodologies are strategies for organizing teams around the goal of designing, building, testing, and releasing software. The methodology you use can make an impact on your costs, how easily you can adapt to changes along the way, how much input you can incorporate from other departments, early users, key stakeholders, and other factors.

Two very different approaches to software development are Waterfall and Agile. They’re great to compare and contrast because they’re very different. While many popular methodologies are variations on Agile these days, Waterfall (a top-down, linear approach) stands in stark contrast to Agile’s (flexible and iterative) approach.

Understanding the Agile vs. Waterfall divide will help you wrap your head around your options, and it will help you to choose a software development methodology that works for your project. This blog post will give you a high-level understanding of both methodologies, and it will help you decide which one will work best for your project.

What is the Waterfall Methodology?

Waterfall is a software development methodology that breaks down the entire development process into linear steps. Created in the 1960s (ancient history in the software world), Waterfall makes intuitive sense to people outside the software industry because it works the way you’d expect traditional projects to work.

For example, if you wanted to build a custom house from scratch, you’d first meet with an architect who would listen to your input and draw up blueprints. The architect would pass the plans along to builders who would lay the foundation, construct the frame, add electrical wiring, etc., all in straightforward, sequential steps. Once they’re done, you’d (hopefully) have the exact house you envisioned from the start. Barring any unexpected problems, it would fall roughly within the budget you set from the start.

Similarly, if you used Waterfall to guide your software project, you would follow a linear path that looks something like this:

  • Determine software requirements
  • Conduct a thorough analysis of all that’s required
  • Design the product
  • Write the code to build the project (implementation phase)
  • Test the product—Quality Assurance (QA)
  • Release the product (take it live)
  • Maintain the product (fixing errors and making improvements as needed)

Step-by-step project management seems pretty logical, right? Planning ahead and sticking to a rigid structure makes perfect sense when you’re building a house or manufacturing a physical product, that’s for sure. After all, if you’re halfway finished with a house and decide you want a bigger kitchen and a smaller guest room, you’ve got to tear down some of the work you’ve done and start over on those areas. It’s going to cost money and time to make that change.

When it comes to software, however, all bets are off. That’s because modifying one feature that will greatly improve the product won’t necessarily impact the others, and you can make changes on the fly (based on user feedback, input from other departments, and testing). That’s where Agile comes in.

It’s easier to make those changes if you choose a more flexible methodology like Agile. And there are some distinct benefits to remaining flexible, which we’ll cover below.

What is the Agile Methodology?

Agile is a software methodology designed for flexibility and adaptation. Agile development teams work in short sprints (usually periods of a week or two) to develop different elements of a software product. Small teams test the features and receive input from the client, other internal teams, and user testing to see what works and what they can improve.

Waterfall vs Agile Methodology: Pros and Cons

What are the Benefits of Agile?

Agile is a powerful methodology that has been used to produce countless software products you know and love. Here are some of its advantages:

  • Flexibility and Adaptability: The Agile approach is amazingly flexible, allowing software developers to incorporate input from other departments (Designers, Business Analysts, UX professionals, executives, etc.) along with users and clients (in cases where a client has outsourced their project to a dedicated software team.
  • MVP-friendly: Agile works well for developing a Minimum Viable Product that will evolve based on user feedback.
  • Customer-centricity: Thanks to its adaptability, it’s easier to deliver products that end-users love.
  • Cross-functional Alignment: By involving experts from different departments in each stage of development, Agile promotes shared ownership of the project. For example, unlike a Waterfall approach, where Designers hand the project over to the Engineers and largely let it go, Agile Designers can work with the Engineers to refine implementation. This promotes a shared commitment to creating superior products.
  • Greater Transparency: Agile’s iterative approach encourages greater transparency, with teams less likely to disappear down the rabbit hole until their deliverables are due.

What are the Disadvantages of Agile?

Of course, all that flexibility does come at a price. Here are a few of the disadvantages of Agile.

  • Harder to Pin Down Budgets: All that iterating, rethinking, and rebuilding based on feedback is valuable, but it’s harder to predict how much it will cost in the end. That’s not to say Agile developers can’t keep costs under control—we use Agile all the time here at Net Solutions and we stay within budget—but if you want exact deliverables at a specific price, Agile might not work.
  • Client Involvement: Some companies that hire dedicated development teams want a hands-off approach, reviewing results only at key transitions. Others like being involved at every step, giving feedback along the way. Agile works great for the latter, not so great for the former.
  • Potential to Lose Focus: Agile’s iterative approach can lead teams astray without strong collaboration and communication.

What are the Benefits of Waterfall?

Waterfall may not be as popular as Agile these days, but it has its benefits. The advantages to using Waterfall include:

  • Budget Control: A top-down plan with clearly defined deliverables makes it easier to predict how much a project will cost. That’s often helpful for government institutions with strict deliverables and budgets.
  • Less Demand on Client: For those who outsource their development, a Waterfall approach might be ideal if they want to take a more hands-off approach.
  • Whole System Approach: Since a Waterfall approach outlines all the deliverables from the start, designers and engineers can develop every component to fit perfectly with the larger whole. This can lead to a more integrated product.

What are the Disadvantages of Waterfall?

The downsides to Waterfall include:

  • Rigidity: Waterfall’s inflexible structure doesn’t lend itself to suggestions for improvement from clients, other departments, and end-users. The only modifications typically come after testing, which takes place near the conclusion of the project.
  • Less Customer-centric: It’s difficult to adopt an MVP model when using a Waterfall methodology, which means software products are designed and built based on what companies think their customers want. Even if they have good Voice-of-the-Customer (VoC) data telling them what users say they want, it’s something else entirely to see how users respond to features in the wild.
  • Department Siloes: Without Agile’s cross-functional teams and inter-departmental communication, Waterfall can lead to a fragmented approach to product creation.

Lean vs Agile vs Waterfall | What is Lean | Difference between Waterfall and Agile

In this video you will learn the difference between waterfall and agile model, what is lean, lean vs agile vs waterfall differences in detail.

Why DevOps is important?

DevOps implementation is going through the roof with most of the largest software organizations around the world invested heavily in its implementation. The core values of devops is effectively based on the Agile Manifesto but with one slight change which moves the focus from creating a working software to one that is more interested in the end-to-end software service mechanism and delivery.

Identifying Non-Functional Requirements (NFR) As Part of Your Agile Project Inception


In addition to the customer value-adding Epics and User stories you typically brainstorm in story writing workshops, the team needs to consider & plan for how to meet critical non-functional requirements that are also essential to the success of the product. These include things like performance, security, reliability, etc. To truly differentiate your product from the competition, think about NFRs not merely as compliance must-haves, but as distinguishing factors and essential contributors to the value proposition of the product. A big part of why our product is superior to the competition could be because it is more secure, more reliable, faster, etc.

NFRs include things like performance, flexibility, usability, maintainability, audit, logging, data migration, availability, reliability, recoverability, traffic/user volume, security, globalization/localization, etc.

In practice, we need to look at each of these non-functional requirements and answer 3 broad questions:

  • What is our _Definition of Success _for this NFR? Exploring this question is critical in order to determine how much time and effort we need to dedicate to this NFR.

Let us take usability as an example: here is an excerpt of the Definition of Success for the Usability NFR from a team I coached recently:

  1. the system should be accessible remotely via a virtual desktop
  2. users should be able to customize the user interface
  3. users should be able to use keyboard shortcuts to access frequently used features
  4. response time for the system should be <n seconds
  5. user should be able to have multiple instances of the system open at the same time
  6. the system should have a usability score on the System Usability Scale (SUS) of 68 or higher.

Kick-Off Your Agile Team With A Working Agreement Workshop

The canvas, created by Avi Schneier and the Scrum Inc team [1], encourages the team to ask questions that go to the heart of team dynamics, from the norms and guidelines they agree to abide by, to the skills they bring to the table and the skills they want to learn from each other, to how they celebrate success and learn from failure. In this article, I will discuss how I adapted Avi’s original canvas to the needs of the teams I was coaching, elaborate on the different elements of a working agreement, and share with you a step-by-step guide to facilitating collaborative working agreement development workshops.

The 8 Canvas Blocks In a Glance:

Team Name and Motto:

Having a team name that all team members can identify with is one aspect of establishing the team’s unique identity. A Team name should be created (and agreed on) by the team on their own. There are many anecdotal accounts[2] about how coming together under a common team name helps the team run much more smoothly and efficiently (Plus, it’s fun to come up with a great team name together!) In a recent working agreement canvas workshop I facilitated, and since there were so many Harry Potter fans in the group, they chose to be called _Team Slytherin. _You should’ve heard the laughs as they attempted to come up with that name!

The Motto is the team’s catch-phrase. Some teams opt for something that captures in a few words what they consider the essence of good teamwork, while others prefer something more tongue-in-cheek. I love to observe the dynamic of a team and how they learn more about each other’s personalities as they try to come up with a motto.

Android Projects with Source Code – Your entry pass into the world of Android

Hello Everyone, welcome to this article, which is going to be really important to all those who’re in dilemma for their projects and the project submissions. This article is also going to help you if you’re an enthusiast looking forward to explore and enhance your Android skills. The reason is that we’re here to provide you the best ideas of Android Project with source code that you can choose as per your choice.

These project ideas are simple suggestions to help you deal with the difficulty of choosing the correct projects. In this article, we’ll see the project ideas from beginners level and later we’ll move on to intermediate to advance.

top android projects with source code

Android Projects with Source Code

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project

Android Projects for beginners

1. Calculator

build a simple calculator app in android studio source code

Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.

To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.

Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.

Source Code: Simple Calculator Project

2. A Reminder App

Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.

To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.

In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.

3. Quiz Application

Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.

To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.

In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.

4. Simple Tic-Tac-Toe

android project tic tac toe game app

Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.

To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.

Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.

Source Code: Tic Tac Toe Game Project

5. Stopwatch

Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.

This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.

6. To Do App

Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.

So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.

Now for users, they will sign up and get access to the write section. Here the users can note down the things and store them permanently. Users can also alter the data or delete them. Finally, they can logout and also, login again and again whenever they like.

7. Roman to decimal converter

Android Project: This app is aimed at the conversion of Roman numbers to their significant decimal number. It’ll help to check the meaning of the roman numbers. Moreover, it will be easy to develop and will help you get your hands on coding and Android.

You need to use Android Studio, Java for coding and XML for interface. The application will take input from the users and convert them to decimal. Once it converts the Roman no. into decimal, it will show the results on the screen.

The users are supposed to just enter the Roman Number and they’ll get the decimal values on the screen. This can be a good android project for final year students.

8. Virtual Dice Roller

Android Project: Well, coming to this part that is Virtual Dice or a random no. generator. It is another simple but interesting app for computer science students. The only task that it would need to do would be to generate a number randomly. This can help people who’re often confused between two or more things.

Using a simple random number generator you can actually create something as good as this. All you’d need to do is get you hands-on OnClick listeners. And a good layout would be cherry on the cake.

The user’s task would be to set the range of the numbers and then click on the roll button. And the app will show them a randomly generated number. Isn’t it interesting ? Try soon!

9. A Scientific Calculator App

Android Project: This application is very important for you as a beginner as it will let you use your logical thinking and improve your programming skills. This is a scientific calculator that will help the users to do various calculations at ease.

To make this application you’d need to use Android Studio. Here you’d need to use arithmetic logics for the calculations. The user would need to give input to the application that will be in terms of numbers. After that, the user will give the operator as an input. Then the Application will calculate and generate the result on the user screen.

10. SMS App

Android Project: An SMS app is another easy but effective idea. It will let you send the SMS to various no. just in the same way as you use the default messaging application in your phone. This project will help you with better understanding of SMSManager in Android.

For this application, you would need to implement Java class SMSManager in Android. For the Layout you can use XML or JSON. Implementing SMSManager into the app is an easy task, so you would love this.

The user would be provided with the facility to text to whichever number they wish also, they’d be able to choose the numbers from the contact list. Another thing would be the Textbox, where they’ll enter their message. Once the message is entered they can happily click on the send button.

10 Writing steps to create a good project brief - Mobile app development

Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.

Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.

Why a Good Mobile App Project Brief Matters?


It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.

For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:

  • Clarity on what your mobile app project “is” and “isn’t” early in development
  • Point of reference for developers, project leads, and clients throughout the cycle
  • Smart allocation of available time and resources based on objective development criteria
  • Streamlined project data storage for further app updates and iterations

Writing Steps to Create a Good Mobile App Project Brief


1. Establish the “You” Behind the App

Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.
