Definition
An adaptive lifecycle, often referred to as agile, is a project management approach characterized by iterative and incremental development. It embraces change and uncertainty by breaking down projects into small, manageable cycles or iterations, allowing for frequent feedback and adjustments. This flexibility enables teams to respond quickly to evolving requirements and deliver value incrementally. In practice, adaptive lifecycles involve continuous planning, execution, and evaluation, with each iteration building upon the last. This approach is crucial for projects where requirements are not fully defined upfront or are expected to change significantly. For instance, developing a new mobile application often benefits from an adaptive lifecycle, allowing for user feedback to shape features throughout development. Unlike predictive lifecycles that rely on detailed upfront planning, adaptive lifecycles welcome change as a natural part of the process. This methodology is a core concept tested on the PMP, CAPM, and PMI-ACP certifications.
