Carousel and process strips

What this lesson covers

1. 01

   Segment the procedure, keep the order

   Mayer’s segmenting principle says learners handle a long procedure better when you present it in learner-paced pieces instead of one continuous stream. Production often hears “pieces” and builds a carousel. That is the wrong chrome when the pieces have a required order. Use a carousel only when each card is a peer: same weight, safe to read in any order. Use a process strip when swapping two steps would make the job wrong or unsafe. SAM’s sprint order belongs in Module 1; this lesson is about which layout encodes order.

2. 02

   Peer cards — equal weight, any order

   These four checks are peers. None must happen before the others, so a carousel is the right layout. A lockout sequence would not belong here.

   One job per screen: The learner can name the action before they click Continue.

   One primary layout: Do not stack a chart, a table, and a compare on the same slide.

   Source under the number: A magnitude without a citation does not ship.

   Arabic rebuilt, not flipped: Labels and focus order follow RTL reading.

3. 03

   Lockout belongs on a process strip

   These steps are not peers. Swapping “verify zero energy” and “apply the lock” is a safety failure, so a shuffled carousel is the wrong layout.

   1 · Notify: Tell affected people the machine will be isolated.

   2 · Isolate: Shut down and disconnect the energy source.

   3 · Lock and tag: Apply the personal lock and the tag with the owner’s name.

   4 · Verify zero energy: Try the start control. Only then begin the work.
