Buyer's guide · checked November 13, 2026

Kaizen software for manufacturing, compared.

The idea board is full. Half the cards are from March, nobody knows which ones were done, and the plant manager wants to know what the program saved this year. Every tool on this page promises to fix that. They differ in who can submit, how ideas are scored and followed up, whether savings are checked, and whether you can see the price.

Below: when a board or a spreadsheet is still enough, ten criteria with the question to ask each vendor, seven tools compared from their own public pages, and where TeamGuru fits and where it does not. We make TeamGuru, so read our row with that in mind.

Is a board or a spreadsheet still enough?

A board is enough when

  • One area, one board, and a team leader who reviews every card at the daily meeting.
  • Ideas are small and done within days, so nobody needs to track savings.
  • Nobody above the area asks how many ideas came in or what they were worth.

Software pays off when

  • Ideas come from three shifts, and nobody can say which ones are waiting for whom.
  • Management asks what the program saved this year, and the answer takes a week of spreadsheets.
  • A good idea on line 1 never reaches line 4, or the other plant.

Either way, the method comes first. The kaizen guide covers the three lanes from quick fix to project and how to verify the benefit; the kaizen events guide covers the workshop. Whatever you agree there is what you will set up in any tool.

Ten criteria, and the question to ask

Ask every vendor to take one of your operators' real ideas through the demo, from the phone to the saving, not their sample case.

  1. Operators can submit without a desk

    The best ideas come from the people on the line. If submitting needs a full license, a laptop or an email address, most of them will not.

    Ask: How does an operator without a company email submit an idea, on what device, and what does their license cost?

  2. Stages you can name

    Every plant runs its own path from idea to standard. The tool should follow yours, with an owner at each stage, not force a generic flow.

    Ask: Can I name and order the stages myself, and who moves an idea from one to the next?

  3. A score the team agrees on

    Without a score, the loudest idea wins. A simple, agreed score such as impact and feasibility makes the choice visible.

    Ask: How is an idea scored, can I change the criteria, and can the score be locked once it is approved?

  4. Actions with an owner and a date

    An approved idea is a promise. It needs actions with a responsible person and a due date, or it waits forever in the approved column.

    Ask: Where do I see every approved idea whose actions are late, and who owns them?

  5. Before and after, with evidence

    A photo of the workplace before and after, and what changed, is what convinces the next team and the auditor.

    Ask: Can a kaizen hold before and after photos and text, and does it show up in the report?

  6. Savings someone believes

    Claimed savings that nobody checked lose the program its credibility with finance. Look for a savings figure per kaizen, over a period, that someone validates.

    Ask: How is a saving entered, over what period, and who confirms it before it counts?

  7. Totals across teams and sites

    Leadership wants the number of ideas, implementation rate and savings by area and plant, without merging spreadsheets.

    Ask: Can I see ideas, implemented kaizens and savings by team, site and year on one page?

  8. Connected to the daily system

    A kaizen program on its own island fades. Ideas should show up where the team already works, and the program's results should be KPIs the plant already reviews.

    Ask: Where do kaizens and their actions show up in our daily meetings, and can ideas and savings become KPIs on our dashboards?

  9. Contractors and suppliers can take part

    Some of the best ideas come from maintenance contractors, cleaning crews and suppliers who see the process from outside. A tool for employees only leaves them out.

    Ask: Can people outside our company submit and work on a kaizen, and what can they see?

  10. A price and a timeline you can plan

    Two of the seven tools below publish a price. For the rest, ask for it in writing, including the cost of operator licenses.

    Ask: What does it cost for my number of operators and sites, and how many weeks until the first ideas come in?

Where TeamGuru fits, and where it does not

TeamGuru runs kaizen as one part of the plant's daily system: operators submit on a light license, the actions sit with the rest of the team's work, and the savings and idea counts become KPIs the plant already reviews. It is the right choice when that connection is what you are missing, not when you want a stand-alone suggestion program with its own app.

What it does

  • Operators submit kaizens as light users, on a cheaper license with a simpler screen. Suppliers and contractors with an account can submit too.
  • Stages are yours to name and order, for example Draft, Go for implementation, Implemented, Published.
  • Each kaizen gets a score, by default impact, originality and feasibility at 1, 3 or 5 points, locked in the stages you choose.
  • Before and after text and photos, comments with @mentions and likes, and actions with owner, due date, % done and Gantt.
  • A kaizen event runs in the same record: the team, the actions as its schedule, the before and after, the impact.
  • An impact summary holds the type of benefit, the saving and its period, with the saving entered weekly or monthly. Once set up, totals by area, site and year show in dashboards and on the TV at the board.

What it does not do

  • No native app, QR code submission or anonymous form; operators use the web app on a phone.
  • No automatic sharing of a kaizen to other sites; a Published stage is how teams flag it. Roll-ups across sites are set up once, not automatic.

Kaizen and light users come with the Enterprise and Unlimited plans. See kaizen, projects and actions and KPI dashboards, or book a demo on your own improvement process from any page.

How we compared

We picked the tools that come up when manufacturing teams search for kaizen and continuous improvement software, read each vendor's own product, pricing and help pages on November 13, 2026, and wrote down only what those pages say. We left out review-site ratings, because we could not read them reliably. We also looked at iObeya and Lean Data Point, whose pages describe no idea workflow, and Gemba Academy, which sells training. If something has changed, or we got your product wrong, write to info@teamguru.com and we will correct it. For a closer look at one vendor, see TeamGuru as a KaiNexus alternative.

Frequently asked questions

What is the best kaizen software for manufacturing?

It depends on how your program runs. For a full operator suggestion program with points and prizes, LeanSuite. For the most complete idea-to-impact system with AI, KaiNexus. For ideas shared across many plants, Rever. For a CI project portfolio, Minitab Engage. For a free start with templates, Mitti. For kaizen in the same system as your KPIs, actions and tier meetings, TeamGuru.

What should kaizen software do that a board or a spreadsheet does not?

Show which ideas wait for whom, give every approved idea actions with owners and dates, keep before and after evidence, and add up ideas and savings by team and site without a week of spreadsheets. The board starts the conversation; the software keeps it from getting lost between shifts.

How much does kaizen software cost?

Most vendors publish no price. Of the eight tools on this page, two show a number: LeanSuite (free idea management for teams of up to 25, one facility from $499 a month) and Mitti (free for up to 10 seats, Premium $24 per seat a month, billed annually). TeamGuru's kaizen module comes with the Enterprise and Unlimited plans, on quote, with lower-cost light users for operators. Checked on November 13, 2026.

How do operators submit kaizens in TeamGuru?

As light users: a cheaper license with a simpler screen, used in the browser on a phone or a shared terminal. Anyone with a TeamGuru account can submit, including external partners such as suppliers. There is no native app, QR code or anonymous form.

Does TeamGuru track kaizen savings?

Yes, per kaizen: an impact summary records the type of benefit, the saving and the period it applies to, with the saving entered weekly or monthly. Totals across kaizens, sites and years are set up once in the metrics module and then shown in dashboards and reports.
