“Institutions are the humanly devised constraints that structure political, economic, and social interactions. They consist of both informal constraints (sanctions, taboos, customs, tradition, and code of conduct) and formal rules”

“Whether computers are used for engineering design, medical data processing, composing music, or other purposes, the structure of computing is much the same. We are extremely short of talented people in this field, and so we need departments, curricula, and research and degree programs in computer science… I think of the Computer Science Department as eventually including experts in Programming, Numerical Analysis, Automata Theory, Data Processing, Business Games, Adaptive Systems, Information Theory, Information Retrieval, Recursive Function Theory, Computer Linguistics, etc., as these fields emerge in structure… Universities must respond [to the computer revolution] with far reaching changes in the educational structure.”

“Information systems, at any level of complexity above that of speech, necessarily involve technologies such as printing, telecommunications, or computers. However, to information science technical potentialities and constraints are of importance mainly in that they affect the social relations concerned.”

“As long as you can Houdini your way out of the Sisyphean constraints then originality happens.”

David Mitchell (1969) English novelist

“Institutions are the humanly devised constraints that structure political, economic, and social interaction. They consist of both informal constraints (sanctions, taboos, customs, traditions, and codes of conduct), and formal rules (constitutions, laws, property rights). Throughout history, institutions have been devised by human beings to create order and reduce uncertainty in exchange.”

“Negotiation is not an act of battle; it’s a process of discovery. The goal is to uncover as much information as possible.”

Chris Voss book Never Split the Difference: Negotiating As If Your Life Depended On It

“Q: Does the creation of Design admit constraint?
Design depends largely on constraints.
Q: What constraints?
The sum of all constraints. Here is one of the few effective keys to the Design problem: the ability of the Designer to recognize as many of the constraints as possible; his willingness and enthusiasm for working within these constraints. Constraints of price, of size, of strength, of balance, of surface, of time, and so forth. Each problem has its own peculiar list.”

“The presence of an enterprise reference architecture aids an enterprise in its ability to understand its structure and processes. Similar to a computer architecture, the enterprise architecture is comprised of several views. The enterprise architecture should provide activity, organizational, business rule (information), resource, and process views of an organization.”

“Decision making processes are aimed at finding courses of action that are feasible or satisfactory in the light of multiple goals and constraints.”
