Reflections on Standard Work

Avatar photo By Jon Miller Updated on May 18th, 2023

Many companies lack documented standards and procedures, including Standard Work. As a cornerstone of the Toyota Production System, Standard Work is distinct from standardization. It is represented on a Standard Work Sheet, capturing layout, flow, people, inventory, quality, and safety. The Standard Work Combination Sheet outlines cycle steps and associated times.

Improving Manufacturing Processes with Standard Work

Standard Work is the optimal blend of manpower, materials, machinery, and methods in manufacturing. It is the foundation for continuous improvement, known as kaizen, as the standard evolves to become more effective.

There are three key elements to Standard Work in a repetitive process:

  1. Takt time
  2. Work sequence
  3. Standard work in process.

However, for processes that lack repetition or exhibit high variability, establishing Standard Work based on these conditions may not be feasible (due to variations in takt time, work sequence, and standard WIP). In such cases, the initial step in kaizen is to eliminate variability and standardize the process, creating a repetitive flow.

Understanding the profound Zen of Lean reveals that all work is fundamentally the same. Embracing this realization facilitates easier execution of tasks, although the perceived rate of change may appear slower in one’s enlightened state.

If you find yourself confused and uncertain about this concept, it indicates significant potential for improvement in your company through the implementation of Standard Work. As mentioned earlier, Standard Work is distinct from standardization, work standards, or standardized work instructions, although there are similarities.

Lean Principles in Action: The Role of Standard Work and Constant Improvement

The two requirements for working in a truly Lean enterprise are:

  1. Follow standard work
  2. Find a better way

Indeed, you are correct in thinking that there is more to it than just that. For those of us who do not have Standard Work in place, there are additional steps to consider. First and foremost, we must establish the standards. Once the standards are set, the next crucial step is to train people to adhere to these standards. Finally, it is essential to regularly audit and verify that the standards are being followed diligently.

Recently, there was an opportunity for reflection on the concept of Standard Work. This occurred during a visit to a client’s site, where two consultants from the company were observed diligently helping the client establish and document Standard Work procedures. However, while examining the developed documentation, an intriguing question surfaced – “Does Gemba have a Standard Work procedure in place specifically for its consultants?”

Despite the fact that many Gemba personnel have extensive factory experience, we must acknowledge that Gemba is not a manufacturing enterprise. Therefore, we can’t presume to fully understand our clients’ perspectives or the exact challenges faced when implementing Lean manufacturing. Nonetheless, we strive to incorporate as many Lean and Kaizen principles and disciplines as possible into our own operations.

Embracing Standard Work for Operational Excellence: A Reflection and Commitment

Implementing Standard Work is critical for any business aiming for ongoing improvement and growth. Regardless of the industry, Lean and Kaizen principles, including Standard Work, offer a path toward better operations. Understanding that all work has fundamental similarities can simplify tasks and foster continual progress.

Despite challenges in introducing Standard Work, especially in variable environments, recognizing the potential for improvement is the first step. By setting clear standards, training staff, and ensuring compliance, any organization can strive toward operational excellence.

    Standard work is something I write about frequently (I’m midway into a 20 part series). Designers -who can resent any workstyle other than an intuitive approach, thinking it impinges on their creativity- seem to have taken well to it. Since designers drive the product cycle, I can only think that more detail/specifics regarding the nature of what constitutes standard work, is what has helped with acceptance of the need to adopt it.
    While my background is manufacturing, I don’t manufacture either but I started to kaizen my shipping procedures to develop standard work and I’ve cut my order processing time by over half. I’m pleased.

    Hi my company has recently embarks on lean. i heard something about standard work. How do you document standard work? Is there any particular “standard” documentation format that is commonly used?

    What is the difference between standard work and standardized work?

    They are the same thing. It was called “standard work” by the Japanese consultants from the Toyota supply chain who were teaching TPS overseas long before Toyota made TPS popular, so many people who learned their lean terminology between 1988 and 2004 or so call it “standard work” and TPS consultants who come directly from Toyota tend to call it “standardized work”.
    Personally I think “standardized work” is an inferior translation of the Japanese term and that “standard work” is more accurate. “Standardized” means something has been brought into conformity with a standard, while “standard” means a norm or requirement. Standard work is not so much conformity against a standard time or method so much as an agreed basis for performing and improving a process.
    At English-speaking Toyota sites they call it “standardized work” and much of the recent literature references this term.

    How do you get your time values and how do you know that they are standardized? You sure can’t just take any observed time. There are all kinds of factors that have to be considered. I would think that MOST might work here, but I have not seen anything that supports this requirement for Standard Work in any article yet. I would appreciate someone’s comments.

    Hi Gary,
    That’s a very good question. I think there is a reason why MOST isn’t often mentioned in articles about standard work. You can find my reply to your question at Ask Gemba.

    The definition of Standard Work is “the most effective combination of manpower, materials and machinery” is simply perfect! Some people only take notes of the operations, and document them. I call it “documented work” only.
    Standardized work aims at the best practices. Moreover, whenever something changes, the documentation should be reviewed to reflect that change. Do not forget to get all people’s approval before going ahead.
    I like the formula: “STD Work = Continuous Improvement”. When I audit the production floor, a signal that the team members are practicing it is to check the initial date vs. the last revision date of the docs (it is a hint of CI).
    I do not have as much experience on STD Work, but I’ve learned form practice, that is a must to make small improvements before writing the documents.

    I love this article. In am currently a part of an organization implementing Kaizen… I am struggling with what appears to be a lack of “standard work” for facilitation in our current Gemba project led by our Sensai. Each meeting seems incongruent and difficult to follow from one day to the next. For someone with a strategic bent like me… I find this hard.

    I standard work –works–It is very helpful in staying organized . It make it a more cleaner area to work. If any thing changes from standard work or any improvements, documentation is updated
