SAM (Successive Approximation Model)
Definition
An agile instructional design methodology that emphasizes rapid prototyping and iterative development cycles. SAM enables faster course development through collaborative design sessions, early stakeholder feedback, and continuous refinement rather than linear sequential phases.
Where it fits in the SDI system
Turn a new process, system, role, or expectation into relevant practice, communication, job support, and evidence people can use in the work.
SDI practitioner lens
From definition to decision
SAM reduces late-stage surprise by putting rough, testable versions in front of learners and stakeholders early. The method earns its speed through focused iteration against a stable performance outcome, not through skipping analysis or review.
01 / Decision it should inform
Use SAM when requirements are uncertain, representative users are available, and the team can make frequent evidence-based decisions about small working increments.
02 / What to watch for
Rapid cycles become churn when feedback is preference-based, decision rights are unclear, or each prototype changes the outcome the project is meant to serve.
