A Methods Constraint is almost aways an Internal Constraint and is a logistic-based constraint of physical movement, process, or data transfer.
A few examples of Methods Constraints include:
Informational Pathway
Process
Interval
Training
Repair
Organization
Delay
Skill Set
Starting Point
These constraints represent and describe the methods you use, could use, or that could result from the way you run your business or process.
Hints:
Could the procedures and techniques that your organization uses result in actions that are incompatible with the goal?
Strict sequencing of tasks may artificially restrict your solution.
Methods Constraints are relative AND sequential. For example, this before that / this predicated on that / this if that.
