Motion Study Software: Eliminate Motion Waste and Lift Manufacturing Productivity

Manufacturers chase productivity through equipment, automation, and planning — yet one of the largest untapped gains hides in plain sight: human motion. Every unnecessary step, reach, bend, search, or reposition consumes time and energy without adding value. Repeated thousands of times a shift, these small inefficiencies become a serious productivity loss. Motion study software gives manufacturers the tools to find, measure, and remove that wasted movement — and to turn a video you already have into a decision about where the time really goes.

What Is Motion Study?

Motion study is a systematic method for analysing how work is performed — hand movements, walking, reaching, tool and material handling, posture, and repetitive actions — so the task can be redesigned for less effort and more output. The objective is simple: identify unnecessary movement and remove it. Reduce that motion and you improve productivity, ergonomics, safety, quality, and process consistency at the same time. It remains one of the most practical tools in industrial engineering and lean manufacturing.

From the Gilbreths to Software

Motion study began in the early twentieth century with Frank and Lillian Gilbreth, who broke work into elemental movements — the “therbligs” such as search, find, select, position, hold, and release. Their insight was that most waste hides inside how a task is done, not just how long it takes. The technology has changed completely since then; the principle has not. Modern motion study software automates the analysis that once required hours of manual observation and a clipboard.

Motion Study vs. Time Study

Motion study and time study are related but distinct. Time study asks how long work takes — cycle times, labour standards, and capacity planning. Motion study asks a different question: is this the best way to perform the task at all? A stopwatch can tell you a job takes forty seconds without ever revealing that ten of them are spent walking to a bin. The strongest results come from doing both on the same footage — measure the time, then attack the motion behind it.

The Hidden Cost of Wasted Motion

A single unnecessary reach or extra step looks trivial. But a manual operation repeats hundreds or thousands of times per shift, and every avoidable movement is multiplied by that volume. Walking, searching for tools, repositioning parts, and awkward postures quietly consume a large share of each cycle without adding any value to the product. Because the loss is spread across thousands of small moments, it rarely shows up on a report — which is exactly why it survives for years.

What Motion Study Software Does

Motion study software lets you record a real operation and then analyse it precisely: replay a cycle frame by frame, break it into work elements, label each element as value-adding or wasteful, compare operators doing the same job, and build an objective record of the current state. Instead of a single averaged number, you get a breakdown of where the time actually goes — which is the foundation for improvement everyone on the floor can see and agree on.

Why Video Changed Motion Study

A stopwatch gives you one number and misses the variation and the movement behind it. Video captures the whole cycle, so you can slow it down, tag each motion, and prove the current state without argument. It also makes analysis repeatable: the same recording can be reviewed by different engineers and revisited months later. This shift — from live observation to recorded video — is what turned motion study from a specialist craft into an everyday improvement tool.

How Yamazo Studio Approaches Motion Study

Yamazo Studio is offline, video-first work-study software. You import shop-floor video and label each work element with an activity verb and object, classified as value-adding, required, or wasteful (VA, NVA, IWR, IWA, or MUDA) — a practical time-and-motion analysis that needs no special hardware. Its Motion Memory feature recalls similar movements you have already analysed and lets you copy the improvement across them, so a fix found once is reused everywhere. The video never leaves your machine.

From Motion to Balanced, Standard Work

The value of motion study is what happens next. In Yamazo Studio the same study flows straight into a Yamazumi chart that balances each station’s work against takt, into line balancing, standardised work sheets, SMED setup analysis, and WERA ergonomic scoring — one integrated pipeline rather than five disconnected tools. Removing wasted motion shortens cycle times, lightens operator load, improves ergonomics and safety, and makes the process repeatable, which is the real foundation of standard work.

Where Motion Study Applies

Motion study pays off in any repetitive manual or semi-manual operation — assembly, packing, machine tending, inspection, kitting, and material handling — across automotive, electronics, appliances, medical devices, and food production. Anywhere people move to do work, there is motion to study and time to recover. It is equally useful for balancing a new line, qualifying a process change, training operators to a standard, and building the evidence base for a continuous-improvement programme.

Getting Started

You do not need a special camera or a cloud account to begin. Record one station on a phone, import the video, and see your first Yamazumi bar in minutes — completely offline. From there you can label the motion, find the waste, balance the work, and write the standard, all in one place. Motion study software simply turns a recording you already have into a clear decision about where your line’s time is really being spent.

Frequently asked questions

What is the difference between motion study and time study?

Time study measures how long work takes — cycle times and labour standards. Motion study examines how the work is done and whether the movement itself can be reduced. They complement each other: time study quantifies the task, motion study improves it. Yamazo Studio supports both on the same video, so you measure and improve in one pass.

Do I need special cameras or hardware for motion study software?

No. A standard phone or camera recording of the operation is enough — you import the video into the software and analyse it there. Yamazo Studio in particular needs no head-mounted rig, no sensors, and no cloud account; a normal shop-floor video is all it takes to start.

Is video-based motion study accurate?

Yes — arguably more accurate than a live stopwatch, because video can be replayed frame by frame and reviewed by more than one person. It captures the variation a single timed observation misses and creates an objective record of the current state that everyone can check, rather than a number that has to be taken on trust.

Does motion study software have to send video to the cloud?

Not with Yamazo Studio. It runs entirely offline after activation — your shop-floor video and analysis stay on your machine and never leave the plant. For manufacturers with data-sensitivity or air-gapped requirements, that on-device model is a core design choice, not an add-on.

Does Yamazo need a separate “therblig” module to do motion study?

No. Yamazo Studio performs practical time-and-motion analysis by letting you label each work element with an activity verb and classify it as value-adding, required, or waste, and by recalling similar movements with Motion Memory. You get the improvement value of motion study — finding and removing wasted movement — without a separate micromotion module to learn.
