The theory of constraints is a systems-based methodology that identifies and addresses the weakest link in a process or system.
Viability theory
Viability theory is an area of mathematics that studies the evolution of dynamical systems under constraints on the system state.[1][2] It was developed to formalize problems arising in the study of various natural and social phenomena, and has close ties to the theories of optimal control and set-valued analysis.
Institutions: abstract model theory for specification and programming | Journal of the ACM
There is a population explosion among the logical systems used in computing science. Examples include first-order logic, equational logic, Horn-clause logic, higher-order logic, infinitary logic, dynamic logic, intuitionistic logic, order-sorted logic, ...
Finite-Choice Logic Programming | Proceedings of the ACM on Programming Languages
Logic programming, as exemplified by datalog, defines the meaning of a program as its unique smallest model: the deductive closure of its inference rules. However, many problems call for an enumeration of models that vary along some set of choices while ...

If a system is to be stable, the number of states of its control mechanism must be greater than or equal to the number of states in the system being controlled.
The Architect of Constraints: Why Context Engineering Is the Human Skill That Matters
“If I had an hour to solve a problem, I’d spend 55 minutes defining the problem and 5 minutes solving it.” — Albert Einstein

Against optimization
One of the most inescapable edicts when leading a team is the order to optimize the system towards the organization’s goals.
Leverage Points: Places to Intervene in a System
By Donella Meadows~ Folks who do systems analysis have a great belief in “leverage points.” These are places within a complex system (a corporation, an economy, a living body, a city, an ecosystem) where a small shift in one thing can produce big changes in everything. This idea is not unique to systems analysis — […]
WRKSHP.tools | Cause-Effect Diagram
A cause-effect diagram is a visual tool designed to help you explore and identify possible causes for a problem or an observed phenomenon. This helps you to come up with possible root causes for the problem you observed, that you can then use to build experiments around.
Object-capability model
The object-capability model is a computer security model. A capability describes a transferable right to perform one (or more) operations on a given object. It can be obtained by the following combination:
