5 focusing steps
Identify the current constraint (the single part of process that limits the rate at which the goal is achieved)
Identify
Increase uptime
1. Run during breaks, mealtimes, off hours, and evenings
2. Bring in more community help
3. Hire outside workers
Make quick improvements to the throughput of the constraint using existing resources (i.e. make the most of what you have)
Exploit
Protect exiting uptime
1. Schedule or buffer for uninterrupted supply of parts or raw materials.
2. Maintain supply of backup tools and spare parts/
Review all other activities in the process to ensure that they are aligned with and truly support the needs of the constraint.
Subordinate
Increase efficiency of output
1. reduce setup time through SMED techniques
2. Combine operations
If the constraint still exists consider what further actions can be taken to eliminate it from being the constraint.
Elevate
Reduce demand
1. Offload part to other resources
2. Eliminate part
Once a constraint is resolved the next constraint should immediately be addressed
Repeat
Different types of constraint
1. Physical constraints
2. Policy constraints
3. Paradigm Constraints
4. Market Constraints
