Text of Standardized Work

  • 1. Production System Effiency STANDARDIZED WORKTRAINING

2. Definition Standardized Work

  • A timed description of the best possible succession of basic manual tasks for an operator.
  • It includes:
  • transformation and control operations
  • but also movements
  • other necessary steps included in the cycle time.

3. Objective

  • Achievement of safety, quality, productivity and delivery performance objectives through:
  • reduce dangerous movements
  • apply controls and ability to repeat
  • correct use of machines
  • identification and elimination of the 7 wastes
  • training and evaluation of the operators

4. Key Factors

  • Allows the repeatability of the sequence of basic tasks during each cycle with low variability of the process.
  • Work content may differ according to product options
  • Separate the man and machine
  • Reduce frequencial operations (reduce variability)
  • Quick and efficient treatment process of improvement ideas through the operator

5. Cycle Time and Takt Time Takt time is a rate that represents, in seconds, the number of parts the customer expect us to deliver Cycle time is a rate, in seconds, at which the product must be produced in order to offset waste in the system and achieve the Takt Time needed to satisfy the customer 6. Work Content Sum of the basic tasks carried out at each workstation to obtain a complete and good product (amount of work for a part) It is measured by timing the cycle of each operator using a cycle time measurement form.The measurement must be based on 20 consecutive cycle times (everything included).Time necessary for self-inspection has to be included. For each operator, we will show the minimum time,wait time excluded ,as well as the maximun and mean time. 7. FORMS

  • The standardized work goal is based on 3 forms:
  • Standardized Work Chart (FAU-F-PS-5006 )
  • Work Combination Table ( FAU-F-PS-5007 )
  • Standard Operation Sheet ( FAU-F-PS-0241 )

8. Standardized Work Chart

  • - describes the succession of basic tasks and the position of the operator for each of them.
  • helps to visualize easily the operator movements and to identify useless movements
  • determines the number of parts between each workstation.

9. Standardized Work Chart 10. Work CombinationChart

  • gathers all the basic identified tasks on the Standardized Work Chart and details each specific time.
  • helps differentiate times walking and waiting from working on the workstation.
  • allows to evaluate the difference between cycle time and takt time and to verify that operators do not wait for the machine.

11. Work CombinationChart 12. Standard Operation Sheet

  • details all the instructions to realize an operation at a workstation describing it by the safest, easiest and most efficient way.
  • contrary to the standardized work chart and work combination table relative to an operator, this document is linked to a process or a basic operation from the process.
