Show the math and assumptions

Each option receives a 1–5 rating for each factor. The tool multiplies that rating by your 1–5 importance setting, then compares the totals.

How to read this

The yellow result is the main planning answer. Change any uncertain input to see whether the answer is stable. Treat this as a starting point for a small real-world test, not a promise.

About the score

This is a relative fit score—not a predicted improvement or probability of success. You choose the importance weights; the Lab supplies the technology ratings.

Wireless light-directed

Flexible point-of-work guidance and confirmation without fixed wiring.

91/100

Paper / labels

Low entry cost; weak closed-loop control.

78/100

Wearable scan

Reduces scanner handling while preserving barcode confirmation.

74/100

Handheld barcode scanner

Strong product and location checks; occupies a hand and attention.

73/100

Voice

Excellent hands-free fit; noise and user acceptance require testing.

72/100

Fixed pick-to-light

Fast, intuitive fixed-location execution with wiring/infrastructure.

68/100

Mobile-robot assisted

Mobile robots can reduce travel; traffic, charging, fleet size, and software still require design.

64/100

Vision / projection

Powerful context; lighting, occlusion, calibration, and cost matter.

60/100

Voodoo disclosure: Voodoo Robotics sells wireless light-directed systems. The same rating method is applied to every option.

What to check nextTest the top two or three options with real noise, gloves, lighting, labels, software delays, common problems, and the manual backup process.

After the calculation

Test the answer on a small piece of real work.

Measure today’s result first. Write down what success means, what can go wrong, and how workers will continue if the new method fails.
