# Completeness Theorem of Information Precedence

From Cibernética Americana

## Preface

Verbatim HTML authoring of original §.

## Overview

The method of information precedence analysis had a fundamental property which makes it a very efficient tool: it is *complete* in a certain sense. An information system for management control has the purpose of making integrated management possible.

## Theorem

### Propostion 1

#### Corollary

### Proposition 2

### Theorem 1

Each information set in a management information system must be a precedent (of some order) of at least one operation station.^{[1]}

### Theorem 2

Completeness theorem. *Each and all relevant information sets in a management information system can be determined, and defined, by an information precedence analysis which starts at every operating station*.

## Discussion

## Notes

- ↑ We are talking here of
*operations*management. Strategic[al] planning systems, for instance, do not satisfy Proposition 1. Hence the theorems 1 and 2 do not hold for such systems.
