The choice of methodology is crucial for project success. Each approach has its own unique way of handling planning, execution, and delivery, with distinct advantages and challenges. Therefore, understanding the best methodologies for custom software development will help you collaborate more effectively with your development team and set realistic expectations for your project.
Agile Development Methodology
Agile is a popular software development approach emphasizing iterative progress, adaptability, and collaboration. It breaks projects into phases, allowing teams to prioritize and release the most valuable features first while continuously adjusting focus.
Implementation steps:
- Prioritizing Requirements: Rank features by their value and feasibility to ensure the most impactful and achievable elements are addressed first.
- Software Design: Create flexible and scalable architectural plans that can adapt to future changes.
- Software Development: Code the prioritized features using industry best
practices to ensure high-quality and maintainable software. - Developer & Stakeholder QA: Test the functionality thoroughly and gather user feedback to identify and address any issues or improvements.
- Iterative Step Release: Deliver working software in small increments to provide continuous value and allow for regular feedback.
- Continuous Improvements: Refine the product based on the feedback and reviews received to enhance its performance and user satisfaction.
- Launch: Officially release the product with all necessary support systems ready to ensure a smooth transition and ongoing assistance.
Agile methodology excels in projects with unclear or changing requirements, offering flexibility and potential for higher profits. However, it demands intensive engagement and ongoing communication from all participants.

Waterfall Development Methodology
The Waterfall method, also known as the linear sequential life cycle model, follows a rigid, sequential approach with distinct iterative phases called “waves” that must be completed before moving to the next.
Implementation phases:
- Analysis of Requirements: Gather and document all project needs to ensure a clear understanding of the objectives and constraints.
- Software Design: Create comprehensive system architecture plans that outline the structure and components of the software.
- Software Development: Develop the full system following the design specifications to ensure consistency and alignment with the initial plans.
- Testing & QA: Thoroughly verify the system’s functionality and quality to identify and fix any issues before release.
- Software Deployment: Release the completed product to users, ensuring it is fully operational and accessible.
- Continuous Maintenance: Provide ongoing support and system updates to address any issues and improve the software over time.
The Waterfall method prioritizes comprehensive upfront planning and documentation, with each phase requiring full completion before moving to the next.
This rigid, linear approach offers clear structure and predictability but lacks flexibility. While beneficial for well-defined projects, it struggles to accommodate changes or unforeseen issues that emerge later in development, making it less adaptable than iterative methodologies.

Minimum Viable Product
The Minimum Viable Product (MVP) approach is a software methodology that focuses on developing a basic version of a product with core features to quickly gather user feedback and validate ideas.
In custom software development, an MVP allows organizations to test their concept, collect valuable data on customer response, and iteratively improve the product based on real-world usage until a working product is completed.
This lean startup approach enables companies to minimize risk and resource allocation by releasing a prototype that addresses essential
user needs, rather than investing heavily in a fully-featured product upfront.
By employing the MVP method, businesses can make data-driven decisions to refine their software, ensuring it aligns closely with market demands and customer expectations.
This method offers several advantages, including quickly gauging customer interest and testing core functionality, saving time and resources by focusing on essential features first.
It’s particularly beneficial for budget-conscious projects and helps prevent wasted effort on unwanted products.
However, potential drawbacks include the need for clients to fully understand and accept the process, as the initial product will be simple and prioritize functionality over complex design. This approach may not be suitable for projects where a polished, feature-rich product is required from the outset.

Scaled Agile Framework
The Scaled Agile Framework (SAFe) is a set of organizational and workflow patterns that implement agile practices at an enterprise scale. It allows large businesses to achieve the agility of smaller organizations by integrating principles across multiple teams.
SAFe provides structured guidance on roles, responsibilities, and work management, promoting alignment, collaboration, and efficient delivery. It emphasizes a continuous learning culture, customer centricity, and built-in quality throughout the development process.
A key component of SAFe is the Program Increment (PI) Planning phase, which is a high-level event where all teams come together to plan and align on the work for the upcoming increment.
By scaling Lean and Agile methodologies from team to enterprise level, SAFe empowers companies to improve productivity, increase employee engagement, and accelerate product releases.
The framework incorporates concepts like Lean Portfolio Management and Innovation Accounting to extend agility beyond IT to the entire business, fostering a more adaptive and responsive organizational environment.
To implement SAFe, use these 12 steps:
- Reaching the tipping point – Bring your team to the ‘tipping point’ and recognize the need for change.
- Train lean-agile change agents – Educate key individuals who will lead the transformation.
- Train executives, managers, and leaders – Ensure leadership understands and supports the change.
- Create a lean-agile center of excellence (LACE) – Establish a group to guide and support the transformation.
- Identify value streams and ARTs (Agile Release Trains) – Map out the organization’s value delivery and define Agile Release Trains.
- Create the implementation plan – Develop a strategy for rolling out SAFe across the organization.
- Prepare for ART launch – Get ready to kick off the first Agile Release Train.
- Train teams and launch the ART – Educate all team members and begin the first ART.
- Coach the ART execution – Provide ongoing support and guidance to ensure success.
- Launch more ARTs and value streams – Expand SAFe implementation to other parts of the organization.
- Extend to the portfolio – Apply SAFe principles at the portfolio level for strategic alignment.
- Sustain and improve – Continuously refine and enhance the SAFe implementation.
SAFe is built on a foundation of core values and principles that guide strategic project management and shape organizational culture. It is particularly effective for larger organizations with multiple teams and complex workflows.
While SAFe may not be the most cost-efficient option, it excels in delivering high-quality products to market faster, making it ideal for enterprises prioritizing speed and quality over strict budget constraints.

Rapid App Development
Rapid Application Development (RAD) is based on the agile methodology and is a type of software methodology that prioritizes the swift delivery of functional software through rapid prototyping and continuous user feedback. This approach emphasizes creating multiple iterations over extensive planning, allowing teams to quickly refine products without starting from scratch.
By focusing on building and iterating prototypes, RAD ensures the final product aligns closely with user requirements. This results in high-quality, user-centric solutions that meet and often exceed client expectations.
There are typically four phases:
- Requirement Planning – Gather and define project requirements, scope, and objectives while conducting initial planning and feasibility studies.
- Prototyping – Create and refine prototypes and user interface designs through iterative feedback sessions with users.
- Construction – Develop the application through coding, integration, and continuous testing while incorporating ongoing user feedback.
- Deployment – Finalize testing, implement the application in the production environment, and transition to user training and ongoing support.
Rapid Application Development is ideal for small to medium-sized project teams, particularly when time and cost efficiency are top priorities. This approach shines when users are readily available to provide a continuous feedback loop and actively participate throughout the entire project lifecycle, ensuring the final product closely aligns with their needs and expectations.

Scrum
Scrum is an agile framework designed for complex product development. It employs iterative and incremental processes to help teams deliver high-quality products while adapting to changing requirements. Scrum emphasizes collaboration, flexibility, and continuous improvement through a set of defined roles, events, and artifacts.
Scrum operates in 1-4 week Sprints, each beginning with Sprint Planning and ending with review and retrospective meetings. Daily Scrums occur throughout, while product backlog refinement is ongoing.
These events structure the work, but Scrum remains flexible, allowing teams to adapt the framework to their specific needs and changing project requirements.
Key Events:
- Sprint Planning: Plan the upcoming Sprint work to ensure all team members understand their tasks and objectives.
- Daily Scrum: Conduct a brief daily sync and planning meeting to discuss progress, obstacles, and next steps.
- Sprint Execution: Work on the Sprint Backlog items to complete the tasks assigned for the current Sprint.
- Sprint Review: Demonstrate the completed work to stakeholders to gather feedback and validate the progress.
- Sprint Retrospective: Reflect on the Sprint and identify improvements to enhance future performance and processes.
- Deployment: Release the completed work to the production environment, making it available to users.
Scrum is a flexible framework best suited for complex projects with evolving requirements, ideal for teams of 5-10 members. It excels in situations where continuous improvement, frequent communication, and client engagement are priorities, allowing for quick releases and adaptability to changing needs without compromising budgets.
However, Scrum may not be the best choice for projects with tight timelines and fixed scopes, as its iterative nature accommodates ongoing changes. The framework’s success relies on clear role definitions, planned events, and a commitment to transparency and collective ownership throughout the development process.

Kanban
Kanban is a lean project management methodology that optimizes software development by visualizing workflows and maintaining consistent work streams. It uses boards with columns representing development stages and cards for individual tasks, allowing teams to efficiently plan, schedule, and track work.
Kanban focuses on creating customer value, improving processes, and enhancing productivity through clear workflow visualization and effective task management in custom software development. This methodology is often used as a project management method.
There are no specific steps with this method, but there are four metrics to keep in mind:
- Lead time: How long it takes for a task to go through each stage and be marked as completed.
- Cycle time: The amount of time that a team member actively spends working on a task.
- Throughput: Measures the number of completed work items at a specific time, such as a day, week, or month.
- Work-in-Progress (WIP): Measures the total number of tasks in progress at one time.
Kanban is ideal for teams seeking continuous improvement and waste reduction in their development process, especially for simpler projects with a specific timeline. It excels in environments that value visual management and can maintain constant collaboration and board updates.
However, Kanban may not be the best choice for complex projects with loose deadlines, as its flexible nature can lead to extended timelines if not carefully managed. Teams should also consider their ability to commit to regular board updates, as neglecting this aspect can hinder the methodology’s effectiveness.
