“Incremental Delivery” is a common term in agile software development, but what does it really mean? 

Incremental Delivery is an approach where a large project is broken down into smaller, manageable chunks. Each chunk represents a complete feature or functionality, developed, tested, and delivered in shorter cycles called sprints. Each sprint results in a usable, valuable piece of the final product. 

Although some developers may worry about being overwhelmed, incremental delivery is designed to streamline the development process by focusing on delivering valuable features. This approach can lead to a more efficient workflow and reduced stress. 

This article addresses the common concerns about incremental delivery, helping those uncomfortable with the concept due to worries about time constraints or other fears related to the incremental approach. 

Myth #1: We’ll Get Stuck Revisiting Old Code! 

Fear: Developers are concerned that incremental delivery leads to a constant need to revisit and rewrite old code. 

Fact: Rewriting code isn’t unique to incremental delivery—it’s a normal part of software development. As software evolves, updates and changes are necessary to keep it functioning well and to add new features. Incremental delivery accepts this and helps make the process easier by breaking the work into smaller, manageable parts. 

In this approach, each module is small and well-documented, making it simpler to understand when changes are needed. Additionally, the use of continuous integration tools helps ensure that new code integrates smoothly with the existing codebase. This reduces the stress of merging changes and helps maintain a steady flow of progress, easing the fear of constantly revisiting old code. 

Myth #2: We’re Already Deep in a Big Module. Can’t We Finish It First? 

Fear: Teams working on large sections of a project might feel pressured to finish them before moving on to new features. 

Fact: It’s important to focus on what’s most important first. Incremental delivery helps with this by focusing on delivering high-value features early on, even if they are from different parts of the project. This way, teams get valuable feedback sooner and can adjust their approach if needed. 

Think about building a house. Wouldn’t you start by setting up the basic structure before worrying about the kitchen cabinets? Incremental delivery works the same way, prioritizing the key parts first, so you can be sure the foundation is solid before adding the details. This approach helps reduce pressure and makes the work more manageable. 

Myth #3: Breaking Tasks into Tiny Pieces Takes Too Long! 

Fear: Developers might be concerned about the time investment in breaking down large tasks. 

Fact: Upfront planning in incremental delivery saves time in the long run. Breaking down tasks into smaller, well-defined units improves clarity, fosters better communication within the team, and allows for easier identification and resolution of issues early on. A well-defined backlog with smaller, actionable tasks streamlines development and reduces the risk of getting bogged down in complex features. 

Myth #4: Clients Won’t Understand or Appreciate Small Updates. 

Fear: Some might worry that clients won’t be engaged with receiving frequent, smaller updates. 

Fact: Clients value transparency and progress. Incremental delivery keeps them engaged in the development process, allowing them to see tangible progress and provide valuable feedback throughout the project lifecycle. Regular communication and consistent check-ins are often more valuable than a single, large update that takes much longer to produce. 

Myth #5: We Can’t Accurately Estimate Timelines with Constant Changes. 

Fear: Traditional project management relies on fixed timelines, and there’s a worry that constant iterations in incremental delivery make accurate estimation difficult or impossible. 

Fact: Traditional timeline estimations are often inaccurate because they assume everything will go according to plan, which rarely happens in complex projects. Incremental delivery offers a more flexible approach by allowing teams to adjust timelines based on real progress and the insights gained from each iteration. 

Instead of sticking to rigid plans, incremental delivery embraces change and uses it to improve forecasts. When teams work in shorter cycles, they can learn from each one, gaining a better understanding of how long tasks really take and what challenges might arise. This leads to more realistic timelines, and when unexpected changes occur, it’s easier to adapt without derailing the entire project. Ultimately, this approach can lead to a smoother development process that aligns with the dynamic nature of software projects. 

Myth #6: Our Team Isn’t Cut Out for Continuous Collaboration. 

Fear: Teams with limited experience in collaboration might feel apprehensive about the constant communication required in incremental delivery. 

Fact: Collaboration is a cornerstone of successful incremental delivery. The constant communication, feedback loops, and collaboration fostered by this approach strengthen teams and make them more adaptable and responsive to change. 

Myth #7: Managing Frequent Releases Creates Too Much Overhead. 

Fear: Managing frequent releases might seem like a logistical nightmare. 

Fact: The upfront effort required to coordinate and plan incremental releases is outweighed by the benefits. Reduced risk, improved adaptability, and faster time-to-market lead to a smoother development process overall. Think of it as an investment that pays off handsomely in the long run. 

Myth #8: Quality Will Suffer with Smaller, More Frequent Releases. 

Fear: Some might worry that smaller releases translate to lower quality. 

Fact: Incremental delivery promotes a culture of continuous testing and quality assurance. Issues are identified and addressed early in the development cycle, leading to a more robust and higher-quality final product. 

Myth #9: Our Team Prefers the Comfort of a Fixed Plan. 

Fear: The comfort and predictability of a fixed plan might be enticing for some teams. 

Fact: The software development landscape is dynamic. A fixed plan often fails to accommodate the inevitable changes that arise. Incremental delivery offers the flexibility to adjust plans based on evolving project needs, resulting in a more responsive and successful development process. 

Myth #10: Incremental Delivery is Only for Small Projects. 

Fear: Some might believe that incremental delivery is only suitable for smaller projects. 

Fact: Incremental delivery scales effectively. In fact, its benefits are even more pronounced in larger projects. Teams practicing incremental delivery can predict future value delivery with greater accuracy and course-correct if needed, leading to a more successful project outcome.
