fourstep

Fourstep is a term used to describe a process or framework that is organized into four sequential steps. It does not refer to a single standardized method, but rather to a generic four-stage workflow used across different fields. Because it is a naming convention rather than a fixed method, the exact steps and their labels vary by context, though the overall aim is to move from a starting point toward a defined outcome through four phases.

A typical four-step structure follows a progression from problem definition to planning, execution, and evaluation. Common formulations include Step 1 define or identify the objective and requirements; Step 2 analyze or plan, gathering information and designing a solution; Step 3 implement, build, or act; Step 4 review, test, or reflect to measure outcomes and identify improvements. In practice, the four-step pattern appears in problem solving, project management, software development life cycles, quality improvement, and instructional design, among other domains.

Variations exist in how the steps are named and emphasized. Some four-step models align closely with established cycles such as Plan-Do-Check-Act (PDCA). Others adapt the sequence to fit specific regulatory, industry, or organizational needs, while still maintaining four distinct phases.

Notes and cautions: because fourstep can be used as a generic descriptor or as a brand name for specific products or programs, it is important to clarify the exact meaning from context. When encountered, the term usually points to a four-phase approach rather than a unique, universal methodology.
