When you open an app or website and instantly see the perfect video , suggestion or product? Or, as a developer , found the perfect tool that saved hours of work? Maybe you’re part of a business team turning raw, unstructured data into clear, actionable insights through a simple dashboard. These moments may feel smooth , but behind them lies thoughtful engineering , smart use of data and teams working together to build meaningful experiences.

Lets walk through what really happens — step by step — from planning, writing code to getting into the hands of customers. And along the way , we will look at how powerful platforms like Cloudsmith and expert teams like Hakkoda help make this journey smoother, faster and smarter.

‍

Phase 1: Requirement Gathering & Analysis

Accurate, Complete and measurable user requirements are core pillars for any successful project. Correctly understanding the use case leads to avoid reworks and meet the deadlines ultimately leading to customer satisfaction.

•  Team meet the client to gather expectations, discuss technical needs and review supporting documents. 
• The team reviews the requirements as it is necessary for software design and coding.
•  The Team collaborates cross-functionally bringing together project managers, UX designers, developers, data analysts to prepare detailed documentation and user stories. Tools like Confluence and Microsoft Word are used for documentation , while project management platforms like Jira, Monday.com, Asana and Trello are used to help streamline task tracking, sprint planning and progress monitoring.

Phase 2: System Design

In this phase data architects understand the business requirements and translate them into visual and logical data architecture. It includes ER Diagrams and data flow diagrams that depict complex relationships between tables, views and data sources. The architects ensure that future development ,  whether analytics , reporting or ML is reliable and aligned with business goals. The common tools are Miro board, Lucid Charts, Whimsical etc.

Increasingly, teams are embracing an API-First approach to guide this architecture. Instead of starting with the user interface or database, development begins with designing the API—viewed as the core product and service layer. This strategy simplifies integrations, reduces dependencies, and supports the shift from monolithic systems to modular, microservices-based architectures. API-First development encourages close collaboration across teams, including designers, developers, and stakeholders.The benefits of this approach are significant—greater code reuse, easier scalability, increased flexibility, and improved reliability. Poorly designed APIs can expose security risks or lead to tight coupling between systems.

Overall in this phase, teams work towards defining a high level structure laying a roadmap for quality implementation i.e. a system with good performance , secure and lies with business needs.

Phase 3: Coding

This is when developers sit down , write code , test logic and collaborate on features.

But writing good code isn’t just about syntax. It’s also about : 

•  Following best practices to write code like adding comments, using meaningful variable names
•  Performing Regular Code Reviews
• Keeping things modular and scalable
•  Using Version Control to keep track of code changes. Using branching strategies to facilitate parallel development like Trunk-based development for rapid, small changes with frequent merges into the main branch – for fast-paced teams and continuous delivery. Use feature-based branching or GitFlow for larger, isolated work that needs more review and structured release cycles. 
• Feature Flags/toggles/switches for enabling or disabling features without deploying new code. They are used when testing in production environments, Canary Releases, Rollback-kill switch and server side A/B Testing.
• Setting up CI Tools like Github Actions, Gitlab CI/CD to run a series of tests before merging the code into the main codebase ensuring code quality and preventing bugs.

Phase 4: Testing

After the development team has completed their work now it's time for the test to eliminate the phase. This phase ensures that the code is bug free , functions as expected and performs well under the real world conditions. 

Testing is performed at various levels:

1. DEV  -  stands for Development. This is the most basic level of testing performed at developer level. It is commonly referred to as “unit testing”. In this developers are compared their results with actual expectations. Tools like pytest are used for automating these tests.
2. SIT  -  stands for System Integration Test. At this stage QA Engineers write and run test cases for testing functionality, stability and verify expected results on various scenarios.
3. UAT  -  stands for User Acceptance Test. After the internal team has completed with testing. The application is sent to the client for testing user and overall functionality by a small group of users, generally internal testers.

Under these there are regression testing to ensure that new code hasn’t broken the existing features. Contract tests to check APIs and services meet agreed specifications. Performance testing to speed , responsiveness and stability under various situations.

At each level if some mistake or bug is found or some new functionality needs to be added the application is sent back to the developer for fixing , refinement and enhancement.

‍

Phase 5: Deployment

Developers use a Version Control System (like Git) to track changes and push their code to the Version Control Software like Github, Gitlab or BitBucket. GitOps is a terminology where system changes are tracked in Git, making deployments more reliable, consistent, and easy to roll back if needed. When a new change happens the code is manually deployed to different environments. Instead of deploying software manually, teams now use automated pipelines that handle building, testing, and releasing code.  The environments often have automated jobs scheduled which run at specific time intervals. The team has to keep track of whether the job has executed correctly or not. If some failure happens the team has to fix it. 

Various Deployment strategies such as Blue-Green deployments (where traffic seamlessly switched between identical environments) and canary releases (where updates gradually rolled out to a small group of users) are used to minimize risks , reduce downtown and ensure safer and controlled releases.

Tools like Docker are used to containerize applications, ensuring consistency across development and production. Terraform helps manage infrastructure as code, allowing teams to provision and maintain cloud resources in a version-controlled, repeatable way.

‍

Phase 6: Maintenance

Once the software is live, the journey isn’t over. The tasks include managing new releases, implementing patches and rollback. Alongside this providing user support and guidance through automated AI chatbots, clear documentation and dedicated customer care service is also important. 

Observability is crucial, tracking logs, metrics, and traces helps detect issues early. Tools like Datadog and Prometheus monitor system health and alert teams in real time.

The product is improved through feature updates and user feedback. If something breaks, a solid incident response process ensures quick recovery and minimal disruption.

Widely used Project Management Methodologies 

1. Agile Development Methodology

It is an iterative approach that emphasises collaboration and adaptability. The project is divided into small cycles called sprints typically 14 days. The teams gather feedback at the end of each sprint before moving forward. Scrum is an agile framework which focuses on fixed length sprints, regular meetings and clearly defined roles. The sprint consists of Daily Standup meetings (DSUs), sprint planning meetings and sprint retrospective meetings. 

2. Waterfall Development Methodology

It is a traditional approach where tasks are completed in sequential phases like planning, design, development and maintenance. It is used in projects which have well defined goals and requirements. The challenge with this approach is if some changes in requirements are made it is very hard to traceback and make changes. 

“The choice between 2 methodologies totally depends on the complexity of the project and timelines.”

3. Hybrid approach

Hybrid project management combines elements of different methodologies—most commonly Agile and Waterfall—to bring together the structure of detailed planning with the flexibility of iterative execution. It’s often used in real-world projects where teams plan upfront using Waterfall but execute using Agile practices. This approach is especially useful in enterprise settings where compliance and governance need to coexist with fast-paced development. While it offers the best of both worlds, it also requires strong coordination and clear communication to succeed.

Wrapping Up: Why it Matters

By following a proper development strategy and having a team which is properly trained companies can deliver high quality projects.  A good delivery can lead to increased customer satisfaction and experience , drive revenue growth , improve brand growth and encourage customer-driven innovation.
