JIT

Examples of JIT in the following topics:

• Special topic: just-in-time and lean systems

  • Just-in-time (JIT) is a management philosophy that originated in the 1970s.
  • Taiichi Ohno is credited with developing JIT and perfected it for Toyota's manufacturing plants in Japan.
  • The main goal of JIT is to eliminate anything that does not add value from the customer's perspective.
  • Non-value-added activities are referred to as "waste" in JIT.
  • There are three essential elements that contribute to the successful practice of JIT:

• JIT manufacturing principles

  • Front-line employees play a critical role in successful JIT practice.
  • There are several ways in which front-line employees contribute to JIT success:
  • Unlike a traditional "push" environment where line workers are relatively independent of one another in their work activities, JIT employees are connected by the "demand pull" discipline, where work is not produced unless the downstream work center needs it.
  • The JIT philosophy has evolved from a manufacturing-focused management approach to a set of management principles that can be applied to any organization.
  • "Lean operations" is a term that is replacing JIT, especially in service environments.

• Just-in-Time Technique

  • To meet JIT objectives, the process relies on signals or Kanban between different points in the process.
  • But JIT relies on other elements in the inventory chain.
  • Therefore, JIT is best implemented as one part of an overall lean manufacturing system.
  • This means firms favoring JIT are especially susceptible to flow interruption.
  • Discuss the benefits and disadvantages of using a Just-In-Time (JIT) inventory system

• Total Quality Management Techniques

  • Six sigma, JIT, Pareto analysis, and the Five Whys technique are all approaches that can be used to improve overall quality.
  • The Just-in-Time (JIT) method is a production strategy for improving business return on investment by reducing in-process inventory and associated carrying costs.
  • JIT focuses on continuous improvement to maximize an organization's return on investment, quality, and efficiency.
  • JIT programs often include a focus on Total Quality Control.
  • JIT must be organization-wide and consistent.

• Uniform plant loading, flexible resources, and line/cellular flow layouts

  • The successful practice of JIT means having the right quantities of the right products in the right place at the right time.
  • The enemy of JIT is uncertainty.
  • A JIT environment thrives on predictability in customer demand, production processes, suppliers, and workers.
  • Repetitive process layouts are perfectly suited for driving out non-value-added activities and transitioning to a JIT environment.
  • In contrast, cell layouts promote JIT goals by featuring unidirectional product flows, high visibility, and fast throughput times.

• Total Quality Management

  • In contrast, cell layouts promote JIT goals by featuring unidirectional product flows, high visibility, and fast throughput times.

• Demand-pull production system and quick setups to reduce lot sizes

  • In contrast to the push system, JIT espouses a "demand-pull" system that operates on the rule that work should flow to a work center only if that work center needs more work.If a work center is already occupied with work activity, the upstream work center should stop production until the downstream work center communicates a need for more material.The emphasis on maintaining high utilization is removed in a JIT environment.The focus of a JIT environment is on addressing the challenges that affect the overall effectiveness of the factory (setup time reduction, quality improvement, enhanced production techniques, waste elimination, etc. ) in meeting its strategic goals, rather than allowing excess inventory to cover up inefficiencies that reduce the factory's competitiveness.
  • Driving down setup costs and setup times are key to dramatically improving factory competitiveness in a JIT environment.

• Inventory Types

  • Just-in-time (acronym: JIT) production is a concept to reduce work in process with respect to a continuous configuration of product.

• Operations-Management Tools

  • Toyota (and the concept of kaizen) is a fantastic example of Lean manufacturing and what is called just-in-time (JIT) inventory management.

• Strategies for external relationships

  • Two common practices, Just-In-Time (JIT) and agile inventory approaches, are used to allow suppliers to react more quickly to changes in customer demand.
  • JIT began at Toyota Motor Company but it evolved into a system for continuous improvement of all aspects of the manufacturing operations.
