What is Standardized Work?
Standardized work is one of the most powerful but least used lean tools.
By documenting the current best practice, standardized work forms the
baseline for kaizen or continuous improvement. As the standard is
improved, the new standard becomes the baseline for further
improvements, and so on. Improving standardized work is a never-ending
In my training about Standardized Work, SW means :
Work is a tool to make quality products, based on operator movement,
that is arranged with appropriate sequence without MUDA (non added
Standardized Work’s spirit is a TOOL
so that the function can be equated with other tools such as jig, mould,torque, impact etc.
Without Standardized Work we could not make good quality product
PURPOSE OF STANDARDIZED WORK
1. Describe the method of production to make quality product with safe, effective and efficient
By implementing SW, employees will maintain production, quality, and safe working environment.
2. First step to KAIZEN (improvement).
Standardized Work is the basic foundation for improvement (KAIZEN) and to evaluate and find MUDA, MURA, & MURI.
There will be no improvement without standardized work.
Basically, standardized work consists of three elements:
- Takt time, which is the rate at which products must be made in a process to meet customer demand.
Takt time, derived from the German word Taktzeit, translated best as meter, is the average time between the start of production of one unit and the start of production of the next unit, when these production starts are set to match the rate of customer demand. For example, if the customer wants to buy 10 units per week, and the units are produced during a 40-hour work week, then the average time between the start of one unit and the next should brs, which, given a steady flow through the production plant, will result in a unit being completed every 4 hours (which equates to 10 units per week). A common misconception is that takt time is related to the time it takes to actually make the product – whether it takes 4 minutes to produce the product or whether it takes 4 years to produce the product, the takt time should be 4 hours in this example (of course, the time it takes to produce the product will impact the magnitude of the number of units actually in production at any point in time).(https://en.wikipedia.org/wiki/Takt_time)
- The precise work sequence in which an operator performs tasks within takt time.
- The standard stock in process, including units in machines, required to keep the process operating smoothly.
There are 3 +1 Sheets in standardized work :
1) Production capacity sheet (PCS)
2) Standardized work combination table (SWCT)
3) Standardized work chart (SWC)
4) Standardized Work Instruction Sheet (SWIS)
