HI,
Difference between bottleneck & Constraint in my view
Bottle neck:
A resource with lesser capacity.
There may be multiple bottlenecks for a process or organization.
Improvising the bottleneck does not add value to the process.
Bottleneck is not always a constraint
Constraint :
It is a limiting factor to achieve the required target.
For any process or organization only one constraint will be there.
constraint can be called as a bottleneck.
Prioritize the focus on to the constraint to achieve the results, constraint act as a gate.
Thanks & regards
