Pareto Chart: 20% causes are responsible for 80% of the results. This is one of the seven Quality Control Problem Solving Tools.

PDCA (Plan, Do, Check, Act): 

  • Plan: Top management should use the visioning process in the context of it Business Plan. Hosin Planning translates the Business Plans to action plans, meaningful to all levels of the organization.
  • Do: Answer the what, how, and who for the total number of tiers for your organization; remember, the fewer the number of tiers, the better. Also, this is the time to bring management together and provide them with a basic understanding of Hosin Planning mechanics.
  • Check: On a periodic basis, review the measurements and note what you´ve learned that can help in the future.
  • Act: Make the necessary adjustments to plans and priorities in order to ensure the success of the strategy breakthroughs.

Perfection: Always optimizing value-added activities and eliminating waste.

Planned Maintenance: Maintenance activities that are performed to a set time schedule.

Poka-Yoke: A mistake-proofing device or procedure to prevent a defect during order taking or manufacturing. An order-taking example is a screen for order input developed from traditional ordering patterns that question orders falling outside the pattern. The suspect orders are then examined, often leading to the discovery of inputting errors or buying based on misinformation. A manufacturing example is a set of photocells in parts containers along an assembly line to prevent components from progressing to the next stage with missing parts.

Process: The flow of material in time and space. The accumulation of sub-processes or operations that transform material from raw material to finished product.

Process Capacity Table: A tool for gathering information about the sequence of operations that make up a work process and the time required to complete each operation.

Process Delay: The time that batches or lots must wait until the next process begins.

Process Route Table: A tool that shows the machines and equipment that are needed for processing a component or completing an assembly process. Aids in grouping manufacturing tasks into work cells.

Process Kaizen: Improvements made at an individual process or in a specific area. Sometimes called "point kaizen".

Processing Time: The time a product is actually being worked on in a machine or work area.

Pull: A system of cascading production and delivery instructions from downstream to upstream activities in which the upstream supplier waits until the downstream customer signals a need. A pull system means producing only what has been consumed by downstream activities or customers.

Pull System: One of the 3 elements of JIT. In the pull systems, the downstream process takes the product they need and pulls it from the producer. This customers pull is a signal to the producer that the product is sold. The pull system links accurate information with the process to minimize waiting and overproduction.

Push System: In contrast to the pull system, product is pushed into a process, regardless of whether it is needed. The pushed product goes into inventory, and lacking a pull signal from the customer indicating that it has been bought, more of the same product could be overproduced and put in inventory.
