The SAM (Successive Approximation Model) is an agile, iterative approach to instructional design.

Unlike the traditional linear "waterfall" models (like ADDIE), SAM is all about rapid prototyping, frequent feedback, and constant improvement.

The SAM (Successive Approximation Model), developed by Michael Allen, is a nimble, iterative approach to instructional design.

It was created specifically to solve the "pain points" of the traditional ADDIE model—mainly that ADDIE can be too linear, slow, and prone to "analysis paralysis."

In SAM, you don't wait until the very end to see if a course works. You build a rough version immediately, test it, and fix it.

## The Three Phases of SAM

While there are different versions (SAM1 for small projects and SAM2 for large ones), the core logic follows these stages:

The Preparation Phase:

This starts with the "Savvy Start," a rapid brainstorming event where stakeholders and designers create initial prototypes.

Instead of long meetings, you start sketching.

The Iterative Design Phase:

This is a loop of Design → Prototype → Review. You create a "functional" prototype (not a pretty one) to see if the learning logic holds up.

The Iterative Development Phase:

Once the design is proven, you move into Develop → Implement → Evaluate.

You produce the final version through three "sweeps" (Alpha, Beta, and Gold).

FeatureThe SAM AdvantageThe Potential Risk

Speed

Moves to prototyping almost immediately.

Can feel chaotic to teams used to rigid steps.

Feedback

Errors are caught early in the "Alpha" phase.

Requires stakeholders to be available for constant reviews.

Flexibility

Easy to pivot if the learning goals change mid-project.

Budgeting can be tricky since the "final" path isn't set in stone.

Quality

Constant refining leads to a more polished user experience."Scope creep" is a risk if you don't define the number of iterations.
