Systems Thinking and Theory of Constraints Flashcards
What is Integrated Decision Making
Big Picture Thinking
Thinking Globally, not Locally
What 2 premises is TOC Based on?
The Goal of a business is to achieve sustainable growth now and in the future
A system’s constraint determines it’s output
What are the layers of understanding?
The Thinking Process - What should we change? to what? and how?
Managing human behavior, policy Constraints, and physical constraints
What is the real cost of inventory?
Longer lead times and poor delivery
defects not being detected soon enough
increased cost due to obsolescence, storage costs, overtime
Cost Accounting Basics
Cost per Job
Variable Rate (Materials+revenue) * Jobs done
Variable Rate(1) + Variable Rate (2) … - Fixed costs = profit
What is the 5 step process to TOC
- Identify System Constraint(s)
- Decide how to exploit the constraint
- Subordinate everything to that decision
- Elevate the systems constraints
- if a constraint was broken, repeat
What is a physical constraint
tangible; easy to recognize.
machine capacity, martial/space availability
What is a market constraint
demand for a company’s products and services is less than the capacity of organization
what is a policy constraint
anything not physical.
usually system of measures and methods that governs decisions of the cmopany
What are the types of policy constraints
Mindset constraints
Measures constraints
methods constraints
what is a mindset constraint
a constraint of thought process or culture of the organization blocks design and implantation of measures and methods to achieve goals
What is a measures constraint
a constraint of the measurements system that drives behaviors that are not in line with organizational goals
what are methods constraints
constraints when procedures and techniques used result in actions incompatible with goals
How can we improve physical constraints?
eliminate idle time
reduce setup and run time per unit
improve quality
purchase additional capacity
What is the throughput world?
perspective indicates that we should first focus on producing product
