AGILE DEVELOPMENT METHODOLOGY:

This approach is designed to accommodate change and the need to produce software faster.

Agile values individuals and their relationships and interactions over tools; it features customer collaboration throughout the development process; it responds to change instead of following a set-in-stone plan; and it focuses on presenting working software, rather than documentation.

Teams use the agile development methodology to minimize risk (such as bugs, cost overruns, and changing requirements) when adding new functionality. In all agile methods, teams develop the software in iterations that contain mini-increments of the new functionality. There are many different forms of the agile development method, including scrum, crystal, extreme programming (XP), and feature-driven development (FDD).

Advantages are:

• Agile methodology has an adaptive approach which is able to respond to the changing requirements of the clients
• Direct communication and constant feedback from customer representative leave no space for any guesswork in the system
• Allow users to realize software benefits earlier, with frequent incremental improvements.

Main principles of Agile software development methodology: face-to-face meetings, constant cooperation, early and continuous delivery of the working software, transparency. Whenever there are unexpected or frequent changes either from the client’s side or internal, this model becomes the perfect choice for managers and team leaders.

DevOps DEPLOYMENT METHODOLOGY:

DevOps is not just a development methodology but also a set of practices that supports an organizational culture. DevOps deployment centers on organizational change that enhances collaboration between the departments responsible for different segments of the development life cycle, such as development, quality assurance, and operations.

Six Aspects That Decide DevOps Success: We incorporate in our development practice.

1. Continuous Integration: Through this, we promise early problem detection, faster recovery from failures, quality assurance and less turn-around time before the product is released. It is a great way to avoid last-minute issues and helps in leveraging feedback instantaneously.
2. Continuous Delivery: We take this engineering approach to ensure software update releases in a phased and reliable manner. Through our service, we aim to reduce deployment risks and initiate the deployment process with accuracy. This helps bring down the new release timeframe, improve product quality and work on bugs in a timely manner.
3. Microservices: Through this, we offer a toolset to address any configuration or scripting issues that ensure effective deployment and scaling.
4. Infrastructure as a Code: We offer enhanced resource management through optimally priced implementation and real-time deployments. We aim to achieve improved consistency and also offer quality resource management through a variety of options.
5. Configuration Management: We offer code management and platform automation services which enable instant configuration, establishes a single tool to manage all operations, improve code quality and timely activity report management.
6. Policy as a Code: Codification of infrastructure and its relevant configurations with the cloud helps firms monitor, track, validate and reconfigure infrastructure in an automated procedure. In a cloud environment, this helps you control resources while monitoring their security and ensure compliance.

DevOps is a method for improved collaboration and tighter integration. It’s a practice that automates the processes between software development and IT teams.

Traditionally, people who wrote the code didn’t collaborate with the people who deployed that code. Developers and operations professionals had different objectives and worked on different floors or even buildings. What makes DevOps so brilliant is that it brings the two teams together.

Thanks to the collaboration between developers and operations professionals, the software can be tested faster and more reliably.

WATERFALL DEPLOYMENT METHODOLOGY:

When it comes to software development, Waterfall is the most traditional and sequential choice. Although it’s usually viewed as an ”old school” or outdated method, it’s helpful to understand the history and structure of Waterfall to better appreciate the flexibility of more modern methodologies.

Each stage of development has its own set of deliverables and review criteria. The process can only go forward like water in a cascading waterfall. The team moves one step at a time making sure their work is complete before going to the next phase.

The process is predictable and allows for accurate budgeting and scheduling. This makes Waterfall a perfect fit for fixed-price projects. In fact, lots of our first-time clients prefer to sign fixed-cost contracts in order to reduce risks from a new partnership.

What’s more, after heavy upfront planning and a lengthy discovery phase, the client doesn’t have to spend much time getting involved in the development process.

Some project managers consider Waterfall one of the best software methodologies for distributed teams and working from home.

Advantages are:

• Simple in management and execution.
• Requires less time from the client past the discovery phase.
• Ample documentation helps in onboarding new developers.
• A great fit for fixed-price projects.
• Easier to estimate the final budget/schedule for the whole project.

RAPID APPLICATION DEVELOPMENT (RAD) METHODOLOGY:

Rapid Application Development (RAD) Methodology is created to take the maximum advantage of the development software. It aimed to reduce the amount of construction needed to build a product. RAD is a condensed development process that produces a high-quality system with low investment costs. It’s possible due to the ability to quickly adjust needed things. It aimed at providing quick results.

The Rapid Application Development method is divided into four phases:

• Requirements planning
• User design
• Construction
• Cutover

The user design and construction phases are repeated until the user approves that all of the requirements are met.

RAD proposes that products can be developed faster and of higher quality by:

• Using workshops or focus groups to gather requirements
• Prototyping and user testing of designs
• Re-using software components
• Following a schedule that defers design improvements to the next product version
• Keeping review meetings and other team communication informal

RAD’s advantages are a quick and highly flexible team and a very close relationship with the customer. If changes are expected, RAD will be able to accommodate these much faster than waterfall. RAD is also never too attached to a prototype and is always willing to change it to suit the needs of the customer.
