According to Dr. Dobb's Journal, "Agile software development methodologies are now used in over 40 percent of software development projects. The adoption of agile is driven by the fact that “over 70 percent of even rigorously managed waterfall method software projects fail to meet business objectives."
One of the most important differences between the agile and waterfall approaches is that waterfall features distinct phases with deliverables at each phase, while agile methods have iterations with each iteration delivering a set of working code that is evaluated and evolved based on user requirements.
Traditional waterfall projects are predicated on finishing distinct development phases of analysis, design, coding, and testing. The entire project goes through analysis, before any form of design can commence. Then, all the design must be completed, before any code is written. This cycle is followed, until all requirements are delivered and tested, which often drives a project to extend beyond agreed upon deadlines and budgets, given inherent change and ideation that happens throughout a project.
Agile Equals Fast Delivery
With agile methodologies, teams are formed and rally around the quick delivery of features that are expected to produce the most business value. All features follow the analysis, design, coding, and testing cadence – but in a much more accelerated cycle, allowing for quick promotion of features to users. One of the core concepts of agile project delivery, is the continuous feedback loop from business experts and users. This method of frequent verification of working software enables refinement much earlier in the development process and allows stakeholder to fine-tune the deliverables while they're still easy to change.
Agile Equals Quality
People often make the assumption, that faster delivery of software must mean quality is compromised. However, quality is often higher with agile projects given the focused nature of feature delivery. Development teams implement changes with the most minimally invasive code, and then integrate code often, so any defects introduced are caught much earlier in the delivery cycle.
Agile Meets Real User Requirements
While agile significantly speeds up software development, success still requires organizations to visualize the scope of the project and the project schedule, orchestrate the integration and testing process, and adhere to agile processes. For example, users must review and approve changes before they are merged into the baseline, developers must review each other's code, and code must undergo unit tests. These processes act as checks and balances leading to software that better meets real user requirements.
We are also experienced agile transformation guides. Far too often agile transformations only focus on moving software practices from Waterfall to Scrum delivery models. While important, it's only part of the evolutionary journey. Migrating software practices alone can help promote efficiency, but without full-scale Transformation, it can merely highlight and exacerbate pre-existing challenges.
