The ©TREAT 1,2,3 methodology is a problem solving methodology used by Lean Strategies International LLC that when applied to processes (technical, methodological, philosophical) can effectively reveal root causes related to issues / problems or opportunities in a process and guide users towards solutions for a more stable, effective, efficient and value adding process.

  Takt time is a German phrase for the baton the conductor uses to set the tempo of an orchestra.  In Lean and Six Sigma applications Takt time refers to the rate at which products, information and/or services need to be completed in, to keep up with customer demand.

How to Calculate:

Takt time is calculated by dividing the available time per day by the customer demand.

If the available time per day is 7.5 hours and the customer would like to receive 350 parts per day, what would the calculated takt time be?

  Transportation waste is any unnecessary movement of people, products, materials or information.

Examples:

1. Moving parts across facilities.
2. Walk excessive distances to retrieve tools.
3. Retrieving or storing, information, files and data.

Caused by:

1. Functional or widespread equipment, poor layout.
2. Minnimal cross-training of work centers.
3. Queue points in and out of operations. 
4. Tools not prioritized by usage and located close to the point of use.
5. Information located in "storage" centers.

  Though the spelling of the word “team” does not include an I, the definition does acknowledge that each individual must do their part.  The word team is defined simply as: a group of individuals who come together for a common purpose or to reach a specific objective.​

  The Theory of Constraints is a philosophy that is used to identify the point in a process where constraints and bottlenecks prevent the process or system from achieving its highest level of performance.  To simplify the definition, the theory of constraints tells us that "the throughput of a system is determined by the systems biggest constraint (bottleneck).  
  The Philosophy was developed by Dr. Eliyahu M. Goldratt.  He covered the philosophy in many different books such as: The Goal and Theory of Constraints.  You can click on any of the links in this definition if you are interested in reading one of Dr. Goldratts books.  
  Dr. Goldratt taught that there were five essential steps used in the theory of constraints.  Those five steps are:

1. Identify the constraint.
2. Exploit the constraint.
3. Subordinate other process steps to the constraint.
4. Elevate the constraint.
5. Repeat or continuously improve the cycle.

  Throughput is the rate at which a process or a system reaches its objectives/goals.  The rate was first discussed and heavily analyzed in the book Theory of Constraints.  The metric is most often measured using "rates" or "monetary" measurements (meaning money).  Throughput is often referred to as manufacturing cycle time.

  The Traditional Yield is taken at the final step of a process to measure the effectiveness of the overall process.  This type of measurement does not take into account scrap, rework or any other inefficiencies in a process it only looks at what goes in and what comes out.

Example:
  John is machining 5 parts today.  During the machining phase 2 parts are oversized.  John goes back and machines the parts down to size and they pass inspection giving him 5 good parts.  His yield on the 5 piece run was 100%.

  Total productive maintenance is a maintenance strategy which focuses on achieving improved performance, reduced breakdowns and better quality through the preventative maintenance and effort of employees.  The strategy is based on 8 pillars:

1. Continuous Improvement
2. Autonomous maintenance
3. Planned Maintenance
4. Quality Maintenance
5. Cost Deployment
6. Early Equipment Management
7. Training and Education
8. Safety and Health

​  Target costing is defined as "a disciplined process for determining and achieving a full-stream cost at which a proposed product with specified functionality, performance, and quality must be produced in order to generate the desired profitability at the product’s anticipated selling price over a specified period of time in the future." This definition encompasses the principal concepts: products should be based on an accurate assessment of the wants and needs of customers in different market segments, and cost targets should be what result after a sustainable profit margin is subtracted from what customers are willing to pay at the time of product introduction and afterwards.
  The fundamental objective of target costing is to manage the business to be profitable in a highly competitive marketplace. In effect, target costing is a proactive cost planning, cost management, and cost reduction practice whereby costs are planned and managed out of a product and business early in the design and development cycle, rather than during the later stages of product development and production.
