Gemba Walk Software: What It Should Do and What a Video Record Adds

What a gemba walk is for

Gemba is the Japanese term for the place where value is created: the line, the cell, the warehouse. The walk is not an inspection. Its purpose is to see the actual process, ask the people doing it what gets in their way, and come back with a few problems worth solving.

Three habits make walks useful: a fixed rhythm, a clear focus for each walk (safety, flow, quality or one specific station) and a follow-up on every finding. Software mostly helps with the first and the third.

What gemba walk software does

Most tools in this category share a core set of functions:

• Checklists and templates for each type of walk, editable by the team
• Walk schedules and reminders, so walks happen at the planned rhythm
• Capture on a phone or tablet: notes, photos, sometimes voice
• Findings turned into actions with an owner, a priority and a due date
• Follow-up and escalation when actions run late
• Reports on walk frequency, recurring findings and open actions

Some products are built only for gemba walks; others are general audit or form tools configured for the purpose.

What to check before you buy

• Offline capture: shop floors often have poor coverage. Does capture work without a connection and sync later?
• Editable checklists: can supervisors change a template without the vendor?
• Action tracking: does every finding get an owner and a date, and stay visible until it is closed?
• Speed on the floor: can a finding be logged in under a minute, with one hand?
• Links to other systems: can actions be exported or synced to the tools the plant already uses?
• Data ownership: where are photos and notes stored, and can you take them with you?

What a checklist cannot record

A checklist captures that something was seen: an operator walking to fetch parts, a station waiting, a fixture that is hard to load. It does not capture how long the walking takes, how often it happens per shift, or how much of the cycle it uses up.

That matters when the finding becomes a decision. "The operator walks a lot at station 4" starts an argument. "Station 4 spends 11 seconds of a 52-second cycle walking", to take an example, starts a layout change. The second sentence needs a measurement, and a fifteen-minute walk is too short to make one by eye.

Recording the gemba on video

A short video of the station turns an observation into something that can be measured, replayed and shown to others. A few rules keep it useful and fair:

• Agree with the people being filmed, and with employee representatives or the works council where one exists, before you record.
• Film the process, not the person: the point is the method, the layout and the waits.
• Record several full cycles from a fixed position, so the variation is visible.
• Keep the video inside the plant unless there is a clear reason to share it.

From recording to numbers

Once the station is on video, the analysis follows a fixed sequence:

1. Split each cycle into work elements and time them.
2. Classify each element as value-added, incidental or waste.
3. Compare the stations on a Yamazumi chart against takt time.
4. Write the improvement up as an A3 report, with the before measurement attached.

After the change, the same station is filmed again and the after measurement sits next to the before. The finding from the walk has become a measured result.

How the two fit together

Gemba walk software and video analysis do different jobs. The walk app keeps leaders on the floor, records what they saw and chases the actions. The video analysis takes the stations the walk flagged and measures them.

A plant that has only the first knows where its problems are but argues about their size. A plant that has only the second measures well but may measure the wrong station.

Where Yamazo Studio fits

Yamazo Studio is not gemba walk software. It has no walk checklists, schedules or action tracking. It is a video time study and work measurement product, used for the measuring step after the walk:

• Video time studies, element by element, with each element classified as value-added, incidental or waste
• Yamazumi charts and line balancing against takt time
• A3 reports for the improvement that follows
• Standard work documents once the new method is set

It runs on your own computer, so video recorded on the shop floor stays in the plant.
