Review, edit and certify a time study

Read the timeline, correct the AI's results, certify the study, and use findings, scenarios and comparisons.

Written by Angad Singh

Once the AI has analyzed your video, review its results, correct anything it got wrong, and certify the study. You can then use findings, scenarios and comparisons to improve the process.

Read the timeline

Each operator has a timeline of activities, color-coded by type and synced to the video:

  • Value-added (VA): work that changes the product.

  • Semi-value-added (SVA): necessary work that doesn't add value directly.

  • Non-value-added (NVA): waste.

  • Waiting and unobserved / off station: time the operator is idle or out of view.

Important:Gray (shaded) segments are skipped and not counted. Don't delete them expecting that to change the totals.

Edit the results

  • Double-click an activity to change its start and end time, description or classification.

  • Split an activity to give part of its time to another activity, or join activities together.

  • Add, copy or paste activities, or reassign one to a different operator.

  • Change the process an activity belongs to: double-click it and choose a different process.

  • Use the same wording every time for the same activity. The AI learns your terms.

After editing, click Recertify to recalculate the totals.

Focus on one operator

In the timeline, click Focus next to an operator's name to show only that operator's activities. A list of their activities, with times, appears below the timeline.

Note: The value-added and non-value-added totals at the top still cover the whole study, not only the operator you're focusing on.

Ask the AI to recheck part of the study

If the AI got a stretch of the video wrong, ask it to look again with your instructions instead of fixing every activity by hand.

  1. In the timeline, click Recheck this window.

  2. Set the start and end time of the window to recheck, up to 5 minutes.

  3. Select the operators to recheck.

  4. Describe what went wrong or what the AI should focus on, for example "Operator 1 was working, not waiting" or "Follow operator 3 closely".

  5. Start the recheck. You can keep working while it runs.

  6. Review the result, then click Apply proposal to accept the changes or Keep current version to discard them.

Tip: You can run rechecks on different operators at the same time while you correct others yourself.

Certify the study

Certify a study once you're happy with it.

Certified studies become the AI's reference for future studies of the same process, including your terminology and how you classify activities.

  • For long videos, certify at a high level: correct the VA / SVA / NVA classifications. You don't need to re-time every activity.

  • For each new process, certifying a 10–15 minute clip is a good start.

  • To benefit from new certifications, run older videos again.

Findings and scenarios

  • Findings suggest improvements (eliminate, combine, rearrange, simplify) with the time they'd save. Convert a finding into a Kaizen with one click.

  • Scenarios: save alternative scenarios and compare the minutes and cost saved, using an hourly rate.

Compare studies

  1. Select two or more studies and click Compare.

    Time and Motion Studies page with the Compare and New Study buttons and the Studies and Comparisons tabs above the study cards
  2. View by operator or for the full study. Choose Fit each study or Shared clock.

  3. Click a category in the legend, such as VA, to show only that category. Click it again to reset.

  4. Click Save comparison to keep it on your dashboard, where you can rename it.

Important: When comparing different cameras of the same area, make sure operator names match in each study.
