Unit 6: Successive Approximation Model (SAM)
SAM Overview
Developed by Michael W. Allen, Successive Approximation Model (or SAM) is a collaborative framework that involves close collaboration between instructional designers (IDs), subject matter experts (SMEs), and stakeholders when designing and developing programs/courses that require frequent change.

Strengths & Limitations
Strengths
-
Stakeholder Transparency: frequent reviews eliminate content and learning outcome misalignment.
-
Agile: pivoting does not destroy or derail the project roadmap.
-
Functional Testing: catching issues in Alpha is cheaper than fixing them in Gold or Rollout.​
Limitations
-
​Resource Intensive: constant loops, iterative evaluations, and improvements require high SME and stakeholder availability.
-
Feedback Fatigue: repeatable revisions and 'messy' prototypes can cause teams to grow tired.
-
Budget Creep: iterations may cause extended timelines and constant PM oversight.
The Successive Approximation Model (SAM) is an excellent framework for cross-collaboration and catching errors via prototypes. This framework emphasizes frequent feedback and rapid prototyping and is best used in e-learning/distant learning environments across audiences (K12, higher ed, corporate).
​
Considering several factors, SAM could be beneficial for my minicourse. Including the following strengths:
-
Great for testing the "Digital Toolkit" learning tool
-
Formative evaluation, gaining immediate feedback for immediate improvements
-
For self-directed learners
However, the cons outweigh the pros.
-
Each phase requires too many components and stakeholders
-
Possibly too slow compared to Rapid Instructional Development (RID)
-
My minicourse doesn't require continuous prototyping
-
Constant testing
​
I believe other models that require less stakeholder input and testing may be more suitable for my minicourse.
