Constantly changing scope can be frustrating and lack of a process to manage these changes and translate them into product requirements can cause challenges. It can also be very difficult to measure change and minimize it, especially in the initial stages of development. You can also plan better for future development cycles based on the data of past cycles, helping you use your resources much more efficiently. Accommodating for changes at the end of each short development cycle helps you respond to change faster and more efficiently.
Imagine a team is building an e-commerce project using an iterative development method. Following this method, the team will implement the primary functionalities of this e-commerce platform in the first iteration. Applying the iterative/incremental approach to your development process enables you to resolve issues sooner and thus accelerate the time it takes to achieve an optimal product. Furthermore, this mindset can give you early competitive advantage in your market, enabling faster adoption and, hence, product growth. Sometimes you don’t have complete information about your customers’ needs or are trying to find the right product-market fit.
The first increment is often the core of the product that addresses the basic requirements before supplementary features are added. Every increment builds upon the previous one to produce a working version of the software. Iterative development means releasing a product in phases, which are also called iterations. Developers can also evaluate progress in one stage before proceeding to the next. Iterations are time-boxed, so they must complete a particular development cycle and deliver working code within a certain period. These boundaries keep the project on track and help developers focus on product design and quality.
It also gives you a chance to assess product strategy and how the changes align with it and identify the need to pivot and change the strategy all together if need be. Like everything else, iterative/incremental development has its pros and cons and it’s important to understand the best use cases for it. Each of the phases may be divided into 1 or more iterations, which are usually time-boxed rather than feature-boxed. Architects and analysts work one iteration ahead of developers and testers to keep their work-product backlog full. Iterative and incremental development models are complementary in nature, which is why they are often used together to boost their efficacy and achieve project deliverables.

Roman Gun, Vice President, Product at Zeta Global, discusses his approach to formulating processes around the team’s goals and capabilities. Today, you can find Casper mattresses in retail stores, and this decision has significantly contributed to the company’s growth. Had it not established feedback loops with its customers, Casper’s sales would have continued to plummet and its technology would not have continued to https://www.globalcloudteam.com/ improve. When you’re in the product manager role, managing various threads of information and evaluating customers’ needs, it’s natural to make assumptions. You don’t always have the answers, so you have to make assumptions to make decisions, whether they work out or not. If documentation is not properly planned and baked into the process, you’re often left with little to no documentation through your iterations.
By developing and testing small parts of the product at a time, it’s easier to identify and fix any problems or defects. This can help ensure that the final product is high quality and meets user needs. Iterative and incremental development can help you build higher-quality products and better manage your resources.
Testing
The procedure itself consists of the initialization step, the iteration step, and the Project Control List. The goal for this initial implementation is to create a product to which the user can react. It should offer a sampling of the key aspects of the problem and provide a solution that is simple enough to understand and implement easily.
High-level requirements are defined but the specifics emerge through collaboration and prototypes during each iteration with the focus on responding to feedback through change. Large-Scale Scrum Canvas is a scrum tool built for every scrum team to plan, track and manage scrum projects through an intuitive visual canvas. Whether your software project involves a single team or multiple teams around the world, we keep everyone on the same page, the same canvas. The first step is to gather the initial set of requirements for the software.
Project is started with a comparatively small task or component and increments are made in each cycle of the iterations until desired product is reached. During this process, developers have advantage of evaluating and testing components at each stage and gaining information that would be useful at end stages as well. The team designs the architecture and framework for the software system, considering the requirements defined in the previous step. The planning phase involves identifying the functionalities to be implemented in the initial increment and defining the timeline and resources required for its development. Realistic timeboxes ensure that work is focused, progress is measured and deliverables are produced within the necessary timeframe.
This involves understanding the needs and expectations of the stakeholders and users, the development team works closely with stakeholders to gather and analyze requirements. The third increment is finally released with the customer reviews and favorite functionality, which will build on all the previous ones implemented. The team assembles the system tool and inspects it for design flaws, required features, and other significant elements. That is to say, primary functionalities like the user profiles, items page, shopping carts, favorite, checkout, and customer reviews will be implemented. The first iteration is then developed and tested, and feedback will be collected to refine the product. With most of the focus being on iterative/incremental process development, tech debt is often overlooked.
Incremental development resists changes to requirements once increments have been planned since this can delay the overall project plan and schedule. Incremental development is well suited for managing risk since risky or complex components can be isolated into separate increments that won’t block the entire project. This predictable approach works well when requirements are clearly defined upfront.
- Gather feedback from your team members regularly, embrace the changing landscape, and celebrate every little win.
- Since every new iteration is an improved version of the previous iteration, it’s easy to maintain discrete versions of the software along with team accountability.
- This way, the development team can provide value to users and stakeholders more rapidly while also incorporating their input into the development process.
- This step involves several key activities that help establish a clear direction and define the scope of work for each iteration.
- Iterative requires a highly experienced Agile team comfortable with ambiguity, rapid changes, prototyping, and soliciting constant user feedback.
- The team assembles the system tool and inspects it for design flaws, required features, and other significant elements.
Gather feedback from your team members regularly, embrace the changing landscape, and celebrate every little win. Using the agile methodology to build an end-to-end software platform helped the company pivot quickly and steadily to achieve high growth in a global market. With fast moving processes and changing scope, documentation often takes a backseat.
Iterative development can also be implemented effectively when project requirements are easy to understand or likely to change in future. More uncertainty suggests more iterations between incremental releases, while clearer requirements allow for longer increments. The incremental approach releases less frequently, typically when each major increment is complete and tested. This allows for rigorous quality assurance on each increment before releasing it. Iterative development takes a more flexible approach with less detailed upfront planning.
According to the dictionary, to iterate implies “to perform or utter repeatedly”. This identifies that the solution may be considered to have a number of architectural layers. The below figure used here relates to a business system development but the concept can also be applied to a non-IT project, such as a marketing campaign.
These cycles or iterations (also known as sprints) give the concept its name. With each iteration, additional features can be designed, developed and tested to add to the program’s functionality. These iterations continue until a fully functional software application is created and ready for deployment to customers or end users. The development team can start by creating a minimum viable product (MVP) with essential features and then release it to gather user feedback. Based on the feedback, subsequent iterations can add new features, improve performance, enhance user experience and address any issues or bugs.
